Simple instructions for making the normal changes needed in the Q1:
Changing the parameters in the Q1:
The normal changes the user might need to change can be found in the menu P42. These include load and unload
pressures, VFD target pressure, time and date, Language and sequencing address, load and start source.
Menu pages are arranged sequentially starting with P00, and each menu contains additional menu page items. If a
particular feature is disabled, certain corresponding menu pages and menu page items may be intentionally omitted and
not displayed. The user profiles in the Q1 consist of the ‘Default’ user, an ‘ADMIN’ user, and ten additional configurable
profiles.
The ADMIN user has full edit access for all menus and because of the possibility of messing everything up, is reserved for
factory settings. Note that changing the wrong parameter can cause many others in many menus to change to new
values, and each would need to be accessed to change back. User profiles ‘USER’, ‘SERVICE’, and ‘SETUP’ are also
configured by default. The DEFAULT user only has access to menus P00 – P09, which are read-only menus. See Table
6.1 for a complete list of user menu permissions.
Changing parameter settings requires menu access permissions from a different user profile (i.e. not the DEFAULT user)
1. Press the ‘UP’ arrow to scroll to menu P09 (‘Access’).
2. Press the ‘ENTER’ key to enter menu P09.
3. Scroll to the desired user profile and press ‘ENTER’.
4. Enter the appropriate access code in the pop-up menu (‘USER’ = 0009, ‘SERVICE’ = 0100).
5. The menus with assigned permissions for the selected user will now be accessible.
6. Press ‘ESCAPE’ to back out of P09.
7. Now scroll up to the appropriate menu and ‘ENTER’ to access the menu containing the item you want to change.
See table 6.01
8. Scroll down and press ‘ENTER’ to access the parameter you want to change. A pop up box will appear to make
the change in, or a message that it is read only when running.
When changing a parameter in a popup box, press ‘ENTER’ to save the newly selected value. Pressing ‘ESCAPE’ will
back out of the selection window and not save any new values selected. Menu tabs are arranged sequentially and in a
continuous loop. The graphical interface inverts to identify the ‘on screen’ navigation location, and the navigation location
is indicated on the vertical scroll bar. Additionally the menu tab extends to identify the navigation location. For example:
Item Description
P19 Menu: Sensor configuration
P19.04 Main motor CT configuration
P19.04.01 CT Range
P19.04.02 CT Windings
P19.04.03 CT Measurement range
Note: menu content items are only visible when the compressor is appropriately configured! Above example will not
appear when the motor protection is not enabled in P14, and P19 is not enabled for your profile. Menu items are indexed
sequentially. If a menu item is not present it is most likely due to configuration! Use the ‘ENTER’ key and the clear key
(ESCAPE) to navigate between menu page navigation and menu content navigation. Entering the menu content area
navigates to the first item of the menu. Use the UP and DOWN keys to navigate between menu content items. Menu
content items are vertically assembled and in a continuous loop. To edit an accessible and editable menu item, navigate
to it and press the enter key. An edit menu popup window will appear. Use the Up and Down keys to select an available
option. Press and hold the Up or Down key to increase the speed at which a selectable value is reached. Press the enter
key to confirm a selection or use the clear key to exit without making a new selection. With the popup window displayed,
press and hold the ‘ENTER’ button to alternate between display text and display value.

Changing the real time clock:
Time can be changed to local time by scrolling to P42, and ENTER. Scroll down to time, and ENTER. Use the up or down
arrows to set the correct time. Check if it is standard time or daylight savings time as the daylight savings time function
makes it easy to change the clock by an hour when needed. ENTER the new time.
Daylight savings time can be easily changed by scrolling to P42, ENTER then scroll down to DAYLIGHT SAVINGS TME,
Press ENTER and move it by an hour. ENTER and it will change the time by an hour. This is a simpler change than
changing the clock when needed.
Resetting the service times after service:
The service timers are located in menu P16, Alarms. These are P16.01 Air filter Service, P16.02, Oil change service,
P16.03, Separator service, and P16.04, Oil Filter Service. These are count down timers, and the new hours before service
is next needed must be entered. Oil life is dependent on your experience and the type of oil you have in your compressor.
Separators are good for 4000 hours or your experience, Oil Filter is 1000 hours and Air Filter is 1000 hours, depending on
your environment. Perform your service and then enter the hours until service is next needed on the work you did.
Other service times may be set up in P16. There are 4 more service timers available to be set up. Consult the P16 section
of the service manual or the factory
There are also provisions for Annual service dates, Weekly service dates, and Biannual service dates. These can be
turned off and on in P11, and set in P16. By default, these are left off as we recommend service based on run time. An
annual service setting might serve to have a distributor service man come out to check the whole system if the customer
is doing their own routine service
Others alarms are set up in P16, but should not be messed with. They are limited by the shutdown fault settings in P17.
These are accessible with the set up menu permissions and not by the P16 service permissions. The service technician
can make some few changes to the alarms, such as moving them to lower values, but should restrict his settings to the
service timers. The serviceman cannot raise the alarms values much.
Setting up the run and pressure schedule:
These steps are outlined in detail in the P21 instructions. Set up is accessible to the user, and the pressure schedule is
turned off and on in P21 once it is set up there.
Setting up the sequencing and lead/lag functions:
P80 has the basic settings for pressure and timing which are user accessible. Sequencing and lead/lag is only turned on
in the master control machine. See P80 instructions. More detailed settings are reserved for the compressor set up
technician. P42 has the address set up for the Metacenter control, and the change in load source for the Metacenter use.
The Modbus symbol will be solid when there is good, uninterrupted communication between units. It will be
flashing slowly if there is not proper communications.

REMOTE START/STOP
When the remote start function is enabled (DI Remote Start), the compressor will do a normal start, as if the run button
was pushed, when the assigned digital input (DI7 by default) changes state from an open to a closed circuit. If closed, the
digital input must be opened and closed again to initiate a remote start. This situation can happen if the machine is
stopped locally with the stop button, or if it is stopped by a power failure and not automatically restarted, or a shut down
fault. Local controller start will be disabled, local stop is always enabled. The compressor will execute a controlled stop, as
if the control panel stop button had been pressed, when the remote start/stop input is open circuit. Should the local stop
be used, the remote stop needs to be opened and closed to reset the remote start
10
REMOTE LOAD
DI 5 closure transfers the load control to a remote contact on DI 6. Contact closure on DI 6 will load and unload the
compressor regardless of the load and unload settings in P42. Local over ride unload will happen at the alarm pressure
setting if the discharge pressure gets up to that point. See parameter P16-13. The alarm set point will always function as a
safety unload signal when there is any kind of remote load, as from the remote digital load, or remote Metacenter or
sequencing load signals.

3.4.2 CONNECTOR X12: 3 PHASE MONITOR

Connect the three phase line voltage to connector X12. This is used to monitor phase direction and phase imbalance on
non-VFD compressors. If the phase direction is connected backward, the Q1 will give an E:0090 (Phase sequence) fault
and prevent the compressor from starting. If there is an E:0090 error switch two of the incoming power lines connected to
the compressor. The connection to X12 and rotation are set at the factory and will be correct unless something has been
disconnected like the phase monitor wires or the motor leads. This is phase only, not a voltage monitor. Low voltage will
not show up.

4 DEFINITIONS & TERMINOLOGY

DEFINITIONS
4.1 SHUTDOWN FAULT
See menu P17. A shutdown fault (immediate stop) is a condition that may present danger or potential damage to the
compressor if the condition persists. A shutdown fault will cause the Q1 to stop the compressor immediately. A shutdown
fault code is displayed that must be manually reset locally to clear once the condition has been resolved or no longer
exists. On power up, if the Q1 finds any conditions which would cause an issue, it will fault out and not run.
4.2 ALARM
See menu P16. An alarm is a warning condition that does not present an immediate danger or potential damage to the
compressor. Alarm states will not shutdown the compressor, nor affect normal operation. An alarm fault code is displayed
that must be manually reset to clear once the condition has been resolved or no longer exists. It serves notice that the
compressor is in need of attention.
4.3 RUN INHIBIT FAULT

See menu P15. A run inhibit fault is a condition that may present a danger or cause damage to the compressor if the main
motor is started while the condition is present. Run inhibit faults are self-resetting and do not prevent the compressor from
running when the condition goes away. A Run inhibit will hold the compressor in a standby state, and will allow the motor
start when the condition is no longer present. A Run inhibit fault code is displayed when triggered, but is not recorded in
the fault log. Run inhibits include low oil temperature and high sump pressure.
13
4.4 UNLOAD PRESSURE
See parameter P42.02. The unload pressure is the delivery pressure level (adjustable) at which the controller will de-
energize the load solenoid output and the compressor will unload. The terms ‘unload’, ‘or ‘off load’ in the Q1 software all
have the same meaning and can be used interchangeably.
4.5 LOAD PRESSURE

See parameter P42.01. The load pressure is the delivery pressure level (adjustable) at which the compressor will energize
the load solenoid output and the compressor will load and make air. If in the standby state, the compressor will start and
load automatically. Any load signal can cause the compressor to start and load automatically, from the run schedule,
sequencing, metacenters, or remote load signal. Remote load signals are inhibited by the compressor local alarms.
4.6 MAIN MOTOR START SEQUENCE

The controller will energize the Star contactor output followed by the Main contactor output 200 ms later. After the
Star/Delta timer (adjustable in P11.01, 2.8 seconds by default) expires the controller will execute an automated Star to
Delta contactor output changeover with a 50ms star to delta transition time. If a Stop command is received during the start
sequence the controller will continue to execute the start sequence before stopping. This action is intended to limit the
break current of motor starter contactors. In a normal across the line start, the main contactor will start when the main
contactor relay is energized. The star and delta relays will be active, but nothing is connected. The Delta relay can be
used as another run relay if needed, considering of course the star delta time delay.
4.7 LOAD DELAY TIMER

See P11.03. The star to delta output transition is immediately followed by a load delay time (adjustable) that will inhibit the
load solenoid output from energizing until the load delay time expires. This is intended to allow the main motor speed to
stabilize and other pre-load functions to occur.
4.8 RELOAD DELAY TIMER

See P11.04. The reload delay time (adjustable) is a period of time immediately following a load to unload event during
which the load solenoid output is inhibited from energizing again to prevent rapid loading and unloading.
4.9 BLOWDOWN TIMER

See P11.07. The blow down time immediately follows a main motor stop. During the blow down time a start is recognized
but is not initiated until the timer expires. P11.07 is primarily used when only one pressure transducer is used. If the sump
pressure (P00.08, AI2) transducer (P18.21) is enabled, then the restart inhibit is also dependent on sump pressure falling
below the ‘start inhibit pressure level’ (P15.04). Sump pressure is optional but included by default. It can be disabled if
need be. If disabled, the blowdown timer should be set for about a minute to allow the sump pressure to fall below 7 psi.
4.10 STANDBY RUN-ON-TIME

See P11.05. When running unloaded, the standby run-on-timer will start. If the compressor remains in an unload condition
and the timer expires, the compressor will stop and enter the Standby state. The compressor will automatically restart and
load as required. This function is intended to improve efficiency during low demand periods and to limit the number of
motor starts. The remaining time in seconds is show on the screen. If it is not desired to have the compressor stop and
standby, set the P11.05 to 0 seconds. The standby run on time will be automatically extended if the starts per hour are
met to prevent the motor from shutting off and restarting too often.
4.11 STOP RUN-ON-TIME

See P11.06. When stopped, the compressor will unload and the main motor will continue to run for the stop run-on-time
before stopping. This function is intended to allow for internal pressure blowdown and to limit lubrication oil aeration prior
to the main motor stopping. The remaining time in seconds is show on the screen. Immediate emergency stops, such as a
shutdown fault, will not have the run on time.
4.12 STARTED STATE

The unit has been started (through the start button, or other start command), and is ready to respond to load commands.
The unit is started and waits in the standby mode until it receives the load signal. It then will go through the load sequence
as if it had been running and unloaded for a while. The motor does not run until there is a load signal. It must be in the
started state for the sequencing or other load control to be effective as they use the load command to start the
compressor out of the stand by state.
14
4.13 RUNNING STATE
The unit is in the Started state AND the main motor is running.
4.14 LOADED STATE

The unit is in the Started state AND running state AND the load solenoid output is energized.
4.15 EMERGENCY STOPPING

Pressing the emergency stop, or allowing the compressor to fault out on shutdown fault, bypasses the stopping sequence
of operations. This is only used to stop the compressor in an emergency, and should never be used for normal non-
emergency stopping.
4.16 OTHER KEY TERMINOLOGY

The Q1 is set up to monitor one temperature reading (‘OIL TEMPERATURE’) and two pressure readings (‘DISCHARGE
PRESS’ and ‘SUMP PRESSURE’) through input X03. These terms are used in the Q1 software.
 The compressor (airend) discharge temperature (‘T1’) is indicated by ‘OIL TEMPERATURE’ (P00.06) and
measured in Analog Input 3 (AI3) on the Q1. In the Q1 software, the term “COMP OUT” refers to the airend itself
and not the whole compressor. The discharge temperature may also the called the ‘COMP OUTLET TEMP’
 The “outlet” pressure is indicated by ‘DISCHARGE PRESS’ (P00.07) and measured in Analog Input 1 (AI1) on the
Q1. This pressure is shown at the top of the screen as the main pressure display, and it is also set as the default
load source in P42.08. It represents the pressure at either the customer connection point (Pressure P2) or at the
Minimum Pressure Valve pressure going into the cooler.
 The compressor discharge (“Sump or internal”) pressure (Pressure ‘P1’) is indicated by ‘SUMP PRESSURE’
(P00.08) and measured in Analog Input 2 (AI2) on the Q1. It is measured at the sump tank (wet side).
 “Device” is a general term which refers to the compressor itself

5 MACHINE STATES & GENERAL OPERATION
5.1 GENERAL COMPRESSOR OPERATION
In general operation, the measured equipment outlet (DELIVERY PRESSURE) regulates the compressor once the
‘START’ button has been pressed. The Q1 will perform condition checks and start the compressor if no condition inhibit
exists.
 If a run inhibit condition exists, the compressor will enter the Started state, but a main motor start will be inhibited.
The compressor will remain in the Standby state and a run inhibit condition message will be displayed.
 If it is started but no load command exists, it will enter the Standby state and wait for the load command, either
from the pressure signal, a remote load command, or a Metacenter control system command
 If a load request exists, the main motor is started in a star/delta sequence and the compressor goes through the
load sequence of events and delays..
When running, after the Wye/delta transition time (P11.01) has expired, the load inhibit time (P11.03) prevents loading for
a period of time to allow the motor speed to stabilize. When the load inhibit time has expired, the load relay output is
energized and the compressor will load. If the unload pressure setting is reached or a remote unload command is
received, the load relay output is de-energized, and the compressor will run unloaded for the unload run time (P11.05)
before the main motor stops and the compressor enters the Standby state. The compressor will load once more if
pressure falls below the load setting before the unload run time expires. From the Standby state, the whole motor start
sequence is performed once more.
When the motor stops, a blow down time (P11.07) is started. If a start request is made during the blowdown time, the
compressor will enter the Standby state until the blowdown time expires. If already in the Standby state and a load
request is present, the compressor will remain in the Standby state until the blowdown time has expired. For units with
sump pressure detection enabled (P18.21), a minimum sump pressure is set to prevent a motor start while the sump is
under pressure. If after 2 minutes, the sump pressure does not fall below the set minimum, a fault condition occurs and
the compressor will not start until it is reset manually. This can be caused by a leak back to the sump from the system, a
faulty blowdown system or plugged blowdown lines. After it unloads, a re-load inhibit time (P11.04) is started that will
prevent immediate re-loading.
Normal automated operation is ended by pushing the ‘STOP’ button, a remote stop command, or in the event of an
immediate stop fault condition. When stopped manually, or by a remote command, the load relay is de-energized. The
main motor continues to run for the stop run time (P11.05).

Control
Description
Mode
Compressor runs load / unload between compressor start and compressor stop. When running
unloaded for longer than the “unload run time” the compressor will stop, go to ‘standby state’
Modulation and automatically restart when requested. The load and unload commands may come from the
discharge pressure, a remote digital command, or from a Metacenter or other sequencer.
The variable speed regulation function provides PID control of a variable speed drive (VFD)
using a 4-20mA speed signal through analog output X01 in order to maintain a steady target
pressure level (VFD Target Pressure P13.02 or P42.18).
In most variable speed applications, however, Sullivan-Palatek utilizes special Modbus
communications between the Q1 and the Yaskawa A1000 drive on the main motor to control
the speed and monitor the drive’s operating parameters. In this case, the analog output is
instead used to send the temperature signal to the fan drive to regulate the cooling fan speed.
Speed regulation is used to maintain package delivery pressure at the VFD target pressure
value (P13.02 or P42.18). If pressure rises to the unload pressure set point, the load solenoid
is de-energized and the compressor unloads. While in the unload state the equipment will
maintain speed at the set unload speed (P13.06) value. After the run on time expires, it will
stop and go into standby mode.
Variable If pressure remains above the load pressure value for longer than the set unload run time the
speed main motor will stop and the equipment will move to the standby state. When pressure falls
below the load pressure set point, the main motor is restarted, the load solenoid output is
energized, and full range speed regulation is then applied.
If connected to a Metacentre™ system controller, or sequenced via the Q1 controller, and the
compressed air system consists of more than one VFD air compressor, only one VFD will
operate as a VFD, varying speed. Other VFD’s called up to load will operate at the optimum
speed (P13.05) setting. In addition, the target pressure of each VSD compressor is
automatically referenced to the Metacentre™ system controller to maintain exact pressure
control regardless of pressure differential between equipment. In this way, up to 24 VFD and
standard modulated compressors in 2 locations can be controlled as a single coherent system
with full efficiency capacity matched management, utilization and single pressure set point
control. With the Metacenter and associated additional equipment, other brand of compressors
can be also controlled for a simple systematic plant pressure source.

When configured, the Blowdown state precedes a compressor running state, and Blowdown
time is a measured period of time used to ensure that the does not start with the presence of too
high of a sump pressure.
5 Blowdown Sump pressure has reached a sufficiently low value to permit the compressor to physically start.
NOTE: Compressor pressure blowdown is a mechanical function performed independently by
the compressor itself. For maximum safety, the time required to vent pressure should never
exceed the Blowdown time configured.
Other conditions can prevent the compressor from physically starting. When this condition
occurs, the display will indicate that the compressor has started.
Physical starting of compressor will occur when condition(s) preventing physical start is
Standby or Started, removed. These include run inhibits, or no load called for. These conditions can occur during
6 normal operation. For example if the start button is pressed when the pressure measured by the
motor not running
compressor pressure sensor is greater than the load pressure setting; the compressor will
remain in standby until pressure falls to the load pressure setting. This is common in sequencing
when all the compressors need to be started to function as a unit, but not physically running. The
display will show standby or started.

6 MENU STRUCTURE
Chapter 6 provides a discussion of the Q1 menu structure and an overview of the available parameters. Menu pages are
arranged sequentially starting with P00, and each menu contains additional menu page items. If a particular feature is
disabled, certain corresponding menu pages and menu page items may be intentionally omitted and not displayed.
The user profiles in the Q1 consist of the ‘Default’ user, an ‘ADMIN’ user, and ten additional configurable profiles. The
‘ADMIN’ user has full access to all menus. User profiles ‘USER’ and ‘SERVICE’ are also configured by default. Table 6.1
provides an outline of default access permissions for each user profile. Menus P00 – P09 are read-only for all users.
To switch between different user profiles, scroll to the desired user in menu P09 (Access) and enter the appropriate
access code (‘USER’ = 0009, ‘SERVICE’ = 0100). See section 6.11 for more information on user access functionality.
While the menus are all sequential in the Q1, certain menus have been moved around or left out of the manual you are
reading if they don’t pertain to you.

The differential pressure in P00.09 is a calculated value, and is represented in the following ways:
00.09 2 1
00.09 00.10 42.05
If the outlet pressure (P00.07) is ever momentarily higher than the sump pressure (P00.08), P00.09 will round to zero, and
no negative values will be displayed.
6.00.10 OIL/AIR SEP DP (P00.10)

P00.10 is a calculated value. It indicates the differential pressure across the oil/air separator, and is represented by the
following calculations.
00.10 00.09 42.05

00.09 00.10 42.05
The Cooling DP (P42.05) is configurable and is used to calculate the Oil/Air separator pressure differential based on the
known measured values of P00.08 and P00.07 (see 6.00.09) and the assumed pressure drop across the cooler as set in
P42.05. From the sump (P00.08), the air must take a path first through the separator, through the minimum pressure
valve, and then through the cooler to reach the outlet of the compressor (P00.07).
P42.05 is utilized whenever the outlet pressure (P00.07) reading is measured after the cooler (P2). For compressors with
a remote cooler (or if the outlet pressure P00.07 is measured at the Minimum Pressure Valve), P42.05 should be set to 0
psi. The ideal value of P42.05 (i.e. pressure drop across the cooler) is dependent on the cooler itself. The default is 3 psi,
but P42.05 can be adjusted as needed per the cooler specifications. On a VFD compressor, this is set to 1 because of the
variation in flow, and thus pressure drop.
6.00.11 Main MTR Current (P00.11)

P00.11 is the current through the main motor of the compressor. In the setup, 2 CT’s are installed to provide the reading.

6.01 SERVICE TIMERS (P01)
Service timers provide a method of managing compressor service condition and preventative maintenance programs that
begin from the compressor commissioning date (i.e. when the compressor was first put into service). The parameters
displayed in P01 are read-only.
Service hour parameters and functions are set in menu P11 under P11.14 – P11.24 (see section 6.11). The
corresponding hour counters in P01 (P01.06 – P01.16) will only be displayed if enabled in P11.
Service hour warning alarms can be accessed and reset in menu P16 under P16.01 – P16.11 (see section 6.16). The
hours set in P16.01 – P16.08 will count down in accordance with P01-06 – P01.13 as the compressor is run. To reset a
service timer, increase the remaining time in P16-01 – P16.08 back up to its original value, or set to values determined by
your experience with this compressor. (See Table 6.16)

the compressor. We will want to know these in working on service issues
The VFD averages will help us know if the compressor was properly sized as well, and helps in dealing with heating and
oil issues.

6.03 ERROR (FAULT) LOG (P03)
Menu P03 is the fault log which provides a log of error conditions. Error conditions can be grouped into 3 categories:
warning conditions, immediate stop (or shutdown) conditions, and run inhibit conditions. Each error condition consists of
an error code and condition text. See menu P08 (section 6.08.1) for a complete list and explanation. When
communicating faults to us for troubleshooting, please give us the fault number, as well as any explanation.
When an error condition occurs, the error is immediately logged and stored in the internal memory of the Q1. In addition to
the error condition being logged, additional key data is simultaneously logged and stored. The error log stores the
previous 50 errors in chronological order beginning with the most recent error condition at menu location P03.01. To view
additional data relating to any error condition, navigate to the error condition in the error log and press ‘ENTER’. Then use
the ‘UP’ and ‘DOWN’ keys to view the data relating to the selected error condition.
Because inhibits are only temporary delays, they are not logged. Alarms do not shut off the compressor, but are logged as
they can be important in troubleshooting issues. Faults take effect a half second after they occur, alarms after 2 seconds.
Thus you may see a fault before the associated alarm happens if the issue was a rapid occurance.
Alarm condition prefix letters:
A: = Warning, E: = Immediate stop (shutdown), R: = ‘run’ inhibit, S: = ‘start’ inhibit. Please note that run and start inhibits
are not recorded as they only are temporary inhibits but will show on the screen and might generate questions.

6.04 EVENT LOG (P04)
The event log provides a log of event conditions. Event conditions include START, whether by button pressed, remote
start, or scheduled start and stop. Also, STOP, parameter adjustment or reset of parameter to default, and USER
ACCESS. When an event condition occurs, the event is immediately logged and stored in the internal memory of the Q1.
In addition to the event being logged, additional data is simultaneously logged and stored with the event. The event log
stores the previous 200 events in chronological order beginning with the most recent event at menu location P04.01. To
view additional data relating to any event, navigate to the event in the event log and press ‘ENTER’. Then use the ‘UP’

Service provider (P05), Q1 controller (P06) and equipment data (P07) are menus that retain specific data regarding the
compressor and the compressor service provider. Note that these menus cannot be configured from the Q1 keypad.
Menus can be configured via a browser (e.g. Internet Explorer) and accessing the menu parameters can be done via an
installed Q1 ECO option card when available. Right now we have Sullivan Palatek information for the service provider as
the card is not available yet. When it is, additional instructions will be provided to retrofit if desired.

6.08 MESSAGE CODES (P08)
ERROR CODE LIST
Message codes are used to annunciate equipment alarm conditions in message code form. Message codes are used to
allow information to pass more freely where language restrictions may exist. Message codes are supported by message
text and condition symbols left and right of text. A flashing symbol to the right of the message code indicates that a
software hard coded delay offset exists (i.e. the offset timer must decrease before the error is annunciated). Menu P08
provides a user reference of all error codes. When calling for service, these codes can be helpful in understanding what
the issue is. Please give the service people both the code and the text description of any alarms or faults, as well as all
errors from the error log, and the events from the event log.

6.09 ACCESS (P09)
The Access menu is used to both manage access and administer access rights to all Q1 users. The user profiles in the
Q1 consist of the ‘Initial’ or ‘Default’ user, an ‘ADMIN’ user, and ten additional configurable profiles. The ‘ADMIN’ user is
the only user profile which has the ability to modify user profile settings, access codes, and menu access permissions.
See Table 6.1 for a list of default menu access permissions for each user profile. There is only one user account active at
a given time. To change to a different user profile, Scroll to menu P09, and ENTER. Scroll up or down to the desired user
and press ‘ENTER’. The pop up menu for each user profile will ask for the access code for that profile. ENTER it and you
will have all the rights and views given to the profile. Press the ESC button to get back to the top so you can scroll out to
other menus. The different profiles will allow access to specific functions but not others. You may give the customer a new
profile and the user code so he can go in and make some minor changes to the operation, such as the load and unload
pressures, time and units, or the service code if he is doing his own service so he can reset the service timers, but he will
be limited as to what he can change and will not be able to make changes to more critical parameters which were set up
by the set up technician. . If in ‘ADMIN’, first select the default user temporarily and then proceed to select the other user
profile as when you are in ADMIN you will be able to make changes to the other user profiles instead of just getting in
them when selected from the ADMIN profile
The unit settings (P09.XX.03 – P09.XX.07) for each user (including ‘ADMIN’) are accessed in P09 and will take effect
whenever that user profile is active. The unit settings in menu P42 (P42.09, P42.11, P42.14, P42.16, P42.17) will be in
effect only when the ‘DEFAULT’ user is the active user. All other settings are global for all users.
The three users we have set up by default are User, Service, and Set up. These cover most all uses and restrictions that
you may need. Admin is reserved for the factory set up here as some of the settings will make a number of other settings
change, and can lead to issues and unintended consequences. Let the factory screw things up, not you! Additional users
can be set up if the 3 already set up are not enough. Additional users can be set up with other access, or with other
languages already set up.

6.10.01 CONTROL MODE (P10.01)

CAUTION: Changing the control mode changes a number of parameters. Changing it back will
NOT restore the original settings that may have been changed. They will go to the default for
the control mode.
The available control modes for the compressor are: ‘Modulation’, ‘Variable speed’. Continuous run is available if the Run
On timer is adjusted to OFF. The active control mode is also displayed in P00.02. See Table 5.2 for a detailed explanation
of each control mode.
NOTE: when selecting ‘Variable speed’, ensure that all parameters in menu P13 have been configured accordingly (see
section 6.13). When in VFD MODE, menus P13, P40, and P41 will be visible. P13 is where the control for the VFD is set,
P40 will monitor the readings off the A1000 when the Yaskawa A1000 is the chosen VFD, and P41 looks at the motor
settings in the Yaskawa A1000. See the sections on these menus for more information.
Some parameters are configured differently by default for “Modulation’ and ‘Variable speed’. This allows the use of one
software version to cover both VFD and non-VFD compressors. The default control mode is ‘Variable speed’, and P10.01
35
can be set to ‘Modulation’ when the Q1 is to be set up for a non-VFD compressor. Upon initial setup, the parameters in
Table 6.10.01 will automatically be adjusted as P10.01 is alternated between ‘Modulation’ and ‘Variable speed’. If certain
parameters are manually changed, the new setting will remain in effect and override any new changes made to P10.01
(indicated by ‘Manual Override’ = YES). The fact that changing from VFD to Modulation and back will reset most
parameters to default is the reason we restrict this menu. The table only shows the main differences in defaults, not the
return to all defaults.

Table 6.10.01, CONTROL MODE DEFAULT SETTING DIFFERENCES
For VFD compressors:

 Drive parameters (RPM, current, and power) are displayed in the home menu (P00) by default for quick
reference. These parameters (P00.03 – P00.05) are not displayed in menu P00 for non-VFD compressors or for
VFD’s which are not Modbus controlled (non Yaskawa A1000). These can be modified here to show other views
of operating parameters on the top of the display.
 Main motor protection (P14.01) is disabled by default. The VFD provides protection.
 Fan motor protection (P14.02) is turned on. The fan motor is protected by the fan VFD, but the fan current is
available for the fault log.
 Incoming phase detection (P16.17 & P17.11) is disabled by default because the drive will always maintain the
proper phase direction to the motor. However, checking for proper phase direction is necessary at factory setup or
if the leads from the drive straight to the motor are ever disconnected for service or installation of the motor.
The “MTR OVLD” function (P18.14) on DI8 is utilized to detect a motor overload trip. On non-VFD compressors, the
normally closed contacts on both the main motor overload and the fan motor overload (if applicable) are wired in series
from C-DI into DI8. If one of the overloads trips, the immediate stop (set in P17.24.01) will stop the compressor
immediately. On any VFD other than that which has Modbus communication, this would be signal a drive fault and be
active. It is also active for soft start as a soft start fault or a fan motor fault. Any of these fault conditions will stop the
compressor and record the operating conditions at the time of the fault for proper troubleshooting.
6.10.02 FORCE UNLOAD (P10.02)

When active (ON), this allows the operator to force the compressor from the load state to the unload state. Once active, to
force unload, press and hold the ‘START’ key and then press the ‘DOWN’ key. The compressor will unload. The
compressor will remain in the unload state until you press the same buttons again. If the run on time expires during the
force offload condition the compressor will blow down and move to the stand by state. This basically allows you to unload
the compressor manually, and keep it unloaded for an extended time without having the load pressure run up until you are
ready to allow normal operation.
6.10.03 COOLING DP (P10.08 or P42.05)

The Cooling DP (P10.08) is configurable and is used to calculate the Oil/Air separator pressure differential based on the known
measured values of P00.08 and P00.07 (see 6.00.09). From the sump (P00.08), the air must take a path first through the separator and
then through the cooler to reach the outlet of the compressor (P00.07).
36
P10.08 is utilized whenever the outlet pressure (P00.07) reading is measured after the cooler. For compressors with a remote cooler (or
if the outlet pressure P00.07 is measured at the Minimum Pressure Valve), P10.08 should be set to 0 psi. The ideal value of P10.08
(i.e. pressure drop across the cooler) is dependent on the cooler itself. The default is 3 psi, but P42.05 can be adjusted as needed per
the cooler specifications by the compressor set up technician. On a VFD compressor, this is set to 1 because of the variation in flow,
and thus pressure drop.
6.10.04 X04 RS485 CONFIGURATIONS (P10.09)

This is configurable for any of the three RS485 uses. X04 is set to Airbus485™’ which is the proprietary setting for all metacenter sequencers.
The only variable in this configuration is the address. The address allows many compressors to be used in different control schemes.
6.10.05 X05 RS485 CONFIGURATION (P10.10)

This is configurable for any of the three RS485 uses. X05 is set to Modbus Master, which is used for communication and control to the Yaskawa
A1000 VFD. As a Modbus communication port, it can have various settings changed if one knows what they are doing. However this works fine for our
use and should never be changed.
6.10.06 X06 RS485 CONFIGURATION (P10.11)

This is configurable for any of the three RS485 uses. X06 is set to Modbus Slave, which is used for accepting new software at the factory. As a
Modbus communication port, it can have various settings changed if one knows what they are doing. However this works fine for our use and should
never be changed.
6.10.07 START SOURCE (P10.12 or P42.07)

Start source is commonly associated with pressing the keypad ‘START’ button. In addition to the keypad ‘START’ button,
the Q1 features configurable alternatives for start source. In this menu, you may configure for ‘Keypad’, ‘Equipment DI’ or
‘Communications’.
Notes:
 Only the selected start source method is active. When selected, all alternative start source methods are inactive!
 Any ‘start’ command merely signals the compressor to move to a started state. A compressor in a started state may
not necessarily start running (e.g. running, loaded). Inhibit functions, timers and the load source configuration will
continue to influence operating characteristics following a ‘START’ command.
 When configured for ‘keypad’ the keypad ‘START’ button functions as the start source. The keypad ‘STOP’ button
functions as the stop source.
 When configured for ‘Equipment DI’, digital input is normally open, close to start, but this can be programmed to be
the opposite. Always, the state must be changed to stop or to restart if stopped by a fault or something else.
Carefully consider the characteristics of the digital input circuit during all operating conditions to determine the
appropriate ‘normal’ state.
 When configured for ‘Equipment DI’, an available digital input must be appropriately configured for ‘COMP start /
stop’. By default, DI 7 is so configured.
 When configured for ‘Communications’ an appropriate RS485 card must be configured for use.
 The local stop button continues to function as a stop. However, if stopped with the stop button. The digital input
must be cycled to the off position in order for it to function as the start again.
6.10.08 LOAD SOURCE (P10.13 or P42.08)

Compressor load source configuration. Select between ‘EQUIP OUT PRESS’, ‘Equipment DI’, or ’Communications’.
Notes:
 When configured for ‘Equipment DI’, Available digital inputs must be configured for Remote load enable AND
Remote load / unload. By default, DI 5 and 6 are so configured
 Remote load enable purpose: Manages compressor master or local control. Can be used to return the
compressor to local if the remote load / unload signal is lost.
 Remote load / unload purpose: Loads the compressor from a remote signal. It allows the compressor to be
controlled by a plant management PLC. When unloaded, it will time out and shut the motor off regardless of the
compressor pressure.
 When configured for ‘Communications’ an appropriate RS485 option must be configured for use. X04 is used for
sequencing which is basically a remote load or unload signal, shut down by timing out the unload run on time
(P11.06). This must be so configured for any sequencing, and appropriate address set.
 Should the pressure rise to the pressure alarm set point, P16.13, it will unload regardless of the load signal from a
remote source.

6.11.02 MIN MTR RUN TIME (P11.02)

The minimum main motor run time is used to fix the main motor minimum run time following a main motor start. Load /
unload state is independent of minimum main motor run time setting (i.e. irrespective of compressor state, the minimum
main motor run time is fixed). Also note that compressor state timers (e.g. Unload run time) remain active and can
influence the total main motor run time. We don’t use this feature.
6.11.03 AUTO RESTART INH (P11.08)

Automatic restart inhibit is used to inhibit automatic restarting of the compressor or to return the compressor to the started
state following a power failure. Once the power has been restored, the compressor will count down the automatic restart
inhibit time period and then return to the started state, be it running loaded or standby unloaded. For standard machines,
5 seconds is a good number, for a VFD unit, it needs to be 30 seconds to allow for the VFD to power up and clear itself of
any power faults. Any faults that were not cleared on power up will remain in effect and must be cleared manually, and
the compressor started again locally.
Note: The automatic restart INH function can only restart a compressor that was in the started state prior to the power
failure. A compressor configured for auto restarting that was not in the started state prior to the power source failure will
not automatically restart. It can restart from stand by or from running, and can return to running or stand by. This is
valuable when using a Metacenter or ISC Sequencing to control multiple compressors and to have them all return to
control when power comes back on.
6.11.04 CONDENSATE DRAIN OPERATION (P11.09 – P11.11)

The condensate drain is the component employed by the compressor to collect and eject condensed water from the
compressor. The drain is typically energized and de-energized using a relay output. Before proceeding to configure drain
open, drain interval and off load drain times, be sure to assign a relay output to ‘Drain’. Sullivan-Palatek utilizes Relay 6
(R6) as the default relay output for the drain.
P11.09: Condensate drain load open time
P11.10: Condensate drain interval time (interval time between condensate drain opening)
P11.11: Condensate drain off load open time (only active during all compressor off load running or other no load times.
Configuring the condensate drain off load open time to ‘OFF’ (default) will disable the condensate drain function during
unload running or other no load started state.
Note: Compressor state influences how the condensate drain interval times are used!
When in the load state, the drain cycle in accordance with P11.09 drain open and P11.10 drain interval times. When the
compressor is running unloaded, any elapsed interval time is stored in memory and the remaining interval time is applied
when the compressor returns to the loaded state..
40
The unload drain time setting can be used to allow minimal air to be lost when the compressor is running unloaded, or has
timed out and shut the motor down.
6.11.05 Starts per Hour (P11.12)

Main motor starts per hour inhibit is the maximum permissible main motor starts in any one hour.
Note: The ‘main motor starts per hour inhibit’ function only influences the unload run time. It will not prevent the main
motor from starting. If a main motor start is performed after the maximum permissible number of main motor starts have
been it will take into account the new start, causing the unload run time to increase. The result of this is you may see the
unload run on time extended to a long time.
6.11.06 DP INHIBIT TIME (P11.13)

Differential pressure inhibit time. This measures the differential pressure between the outlet pressure (AI1, P00.07) and
the sump pressure (AI2, P00.08). Used to filter (ignore) instantaneous or short periods where the differential pressure
alarm or trip levels are exceeded. It prevents nuisance alarms or shut downs.
6.11.07 SERVICE HOURS (P11.14-21)

Service countdown timers are turned on and set up here. Once set up and configured here, they are set in P16. By
default, we set P11.14-17 and the rest are set to OFF. We set none of the timers we use to shut the compressor down if
the clocks run out, but they can be configured to give a warning that the compressor will shut down, then to shut the
compressor down if service in not done in a timely manner.
6.11.08 SERVICE TIMERS (P11.22-24)

Service weekly, annual and biannual timers are turned on here so they can be set in P16. The alarms can then be used to
signal a call out for service on a time or calander basis instead of a compressor run hours.
41
Equipment settings have been arranged over a series of equipment setting menus. Menu items are grouped together,
allowing administrators menu access to equipment setting menus as appropriate. The EQUIP SETTINGS 3 menu allows
users with access to configure critical operating parameters. Some parameters in P12 are not editable while the
compressor is running. Because of the sensitivity of some of these parameters, this is a restricted menu and parameters
we want accessible to users have been duplicated in menu P42. This is also restricted to the factory set up as is P10.

This creates a new configuration file, replacing the existing configuration file. Press ‘ENTER’. Use the ‘UP’ key to select
‘YES’. Press ‘ENTER’. The current parameter values have been saved as the configuration file.
Understand how the Sullivan Palatek Q1 manages parameter data…
 Each Q1 controller is delivered complete with a hard coded environment and configuration file containing the
specific parameter values for this compressor.
 Parameter default values are defined by the application software configuration file.
 Current parameter values are parameter values configured for normal operation and are set in the testing
process. Current parameter values can differ from the original configuration file.
 Saved parameter values are the then ‘Current parameter values’ and saved by the Sullivan Palatek Q1 following
power down. The current parameter values are instantly recovered and re-instated by the Sullivan Palatek Q1
following power up.
 Following a parameter reset the current parameter values are replaced by the original or previously saved
configuration file.
 If the working parameters are saved as a configuration file, then a soft reset will recover these. This can help
when someone has been playing with multiple parameters and you need to get back to a known set of good
values and eliminate and other values or settings.
6.12.02 USE CUSTOM SENSOR (P12.03-05)

The Q1 can accept different pressure ranges besides the standard 0-16 bar (0-232 psi). When used for high pressure
machines, the pressure ranges of both the discharge and sump sensors must be changed. To do this, first they must be
unlocked by setting P12-03 to ON.
Next, you can change the range to the new sensor range. It is always 4-20 ma for the new pressure. The next standard
range is 0-25 bar (0-369 psi). It might be easier to change the units to bar from psi for this as the range on the sensor is
usually called out in bar.
Set the new range in P12.04 for the compressor outlet sensor and P12.05 for the sump pressure sensor.
Once done, reset P12-03 to OFF to lock this in.
6.12.03 RESET AND SET HOURS (P12.06, 07, 09, 10, 11)
This might be used in the event that you replace the Q1 with a new one. The old event and error logs can be erased, and
the hours off the old Q1 can be put in as the new hours to start from.
6.12.04 EI SENSOR ACTIVE (P12.14)

The Q1 can operate with only one pressure sensor. The sump sensor can be turned off. You may need this in the event
one sensor has gone bad and you need to wait for a new one. The blowdown time (P11.07) will need to be increased to
prevent the compressor from trying to start before the sump has blown down. We found in most applications 55-60
seconds is fine.
43
6.12.05 ISC AVAILABLE (P12.15)
The internal sequencing control is often sold as an added option, and when sold is then just turned on. Sullivan Palatek
chooses to make it available as a part of our microprocessor controlled compressors at no additional cost. It is defaulted
ON, making available the internal sequencing feature.
6.12.06 FAN TEMPERATURE CONTROL (P12.17, 18, 19)

When a relay output is chosen for “FAN CONTROL” it uses these settings to determine when to turn the cooling fan on,
how long it should run for a minimum time, and at what temperature to shut the cooling fan off. By default, in
MODULATION MODE, the fan is controlled with these setting in relay R5. In VFD mode, the fan is turned on by the VFD
when the compressor is running at any temperature so as to get some cooling in the after cooler prior to the oil
temperature rising..
6.12.07 BOOT SCREEN BMP (P12.20)

The boot screen can be turned off for a faster boot, or turned to full boot screen for a fancy display of the Q1 capabilities.
We choose a custom boot, with only one simple graphic.
6.12.08 P00.03, 04, 05 CONFIG (P12.21, 22, 23)

These are the user defined display of parameters on the P00 screen. They are inserted near the top of the P00 menu.
These display lines can be set to read any of the reading in the Q1. They can be turned off and just push the lower display
lines up, or set to anything you want the screen to show. We choose to use these in the VFD mode to show some of the
VFD operating parameters, and in modulation, we chose to show the sump pressure and main motor current in the main
screen to provide the user pertinent information at a glance.

6.13 VFD SETTINGS (P13)
Menu P13 manages the relationship between the main VFD and compressor motor. Note that the abbreviations “VFD”
(variable frequency drive) and “VSD” (variable speed drive) can be used interchangeably. Menu P13 will only be
accessible if P10.01 is set to “Variable speed” for VFD operation. Some parameters in P13 are not editable while the

Table 6.13.01, VFD SETTINGS MENU (P13) OVERVIEW
* This parameter is read-only while the compressor is running
6.13.01 VFD CONTROL MODE (P13.01)

The operation of the VFD can be set to operate as a VFD, varying the speed to maintain the target pressure, or it can be
set as a fixed speed compressor, set at a different speed than just across the line. When operating as a fixed speed
compressor, it will run at the optimum speed (P13.05) or if unloaded, at the unload speed (P13.06). When it is operated as
a second VFD called up by a sequencing method, it will run as a fixed speed at the optimum speed until it unloads and is
shut down.
6.13.02 VFD TARGET PRESS (P13.02)

This is the discharge pressure the VFD will try to maintain by speeding up and slowing down as needed. It must be less
than the unload pressure by 3 psi, but other than that it is independently set. It can be over road by pressures set in the
run schedule or sequencing, or by external Metacenter sequencers. For these, their load setting or mid-range setting will
substitute for this target pressure.
6.13.03 VFD MAX SPEED (P13.03)

When running the VFD via communications, this set the maximum speed the compressor can go, but limited by the
maximum speed set in the VFD itself. When running any other VFD not by communications, this has no control, but rather
reads the speed for 20 ma speed signal to the VFD. It is a reference speed reading only.
45
6.13.04 VFD MIN SPEED (P13.04)
When running the VFD via communications, this set the minimum speed the compressor will go. When running any other
VFD not by communications, this has no control, but rather reads the speed for 4 ma speed signal to the VFD. It is a
reference speed reading only.
6.13.05 VFD OPT SPEED (P13.05)

Variable speed drive optimum speed (P13.05) is used to set the speed a VFD will run when it is loaded, but not operating
as a trim machine. This would be the case when there are multiple VFD’s in a compressor control system utilizing a
MetaCentre control system, or using the internal ISC controls in the Q1. This might be around 75% of the maximum
speed, but is determined by the operation within the control scheme, and should be set up as needed when it is needed.
Consult the factory if help is needed with sequencing control.
6.13.06 VFD UNLOAD SPEED (P13.06)

When running the VFD via communications, this set the speed the compressor will run when it is unloaded. This will not
be less than the minimum speed, but may be higher for various reasons. It is normally, however, set to the minimum
speed. When running any other VFD not by communications, this has no control, but rather reads the speed for the ma
speed signal to the VFD. It is a reference speed reading only.
6.13.07 VFD RPM AND CURRENT (P13.07, 08)

These are read only parameters. The RPM is the output speed to the VFD. The current is the analogue output which is
irrelevant if doing control via communication, butif by analogue output this is the 4-20m ma signal to the drive.
6.13.08 VFD CONTROL SETTINGS (P13.09, 10, 11, 13)

These settings are the proportional, integral and derivative settings for the speed control (see diagram below). These can
be set from 0 to 100 %. The ramp rate is a % of the speed which the VFD is allowed to change over time, independent of
the PID factors. It is set between 5 and 100 %. The values we have chosen for the defaults seem to work fine, but are
available for those who want to tweak in tighter pressure control. These are standard instrumentation grade control as
used in many applications in the plant.
6.13.09 VFD SKIP SPEEDS (P13.25-30)

There are a total of 3 skip frequency ranges that can be configured. These can be set to skip a small band that has some
physical harmonics or vibration that is small enough to skip over. This should be limited to about a 3 Hz spread.
When skip frequency 1 low set point (P13.25) is adjusted to a value greater than OFF, skip frequency 1 high (P13.26)
menu and skip frequency 2 low (P13.27) menus are revealed.
Similarly, when skip frequency 2 low (P13.27) set point is adjusted to a value greater than OFF, skip frequency 2 high
(P13.28) menu and skip frequency 3 low (P13.29) menus are revealed.
46
The low and high settings for the skip band are set. The drive also has this capability, and often if a skip frequency is
used, it is set in the drive instead of the microprocessor. However, the Q1 has better capabilities to skip than the drive
has.
Normally, with auto tuning we find there are no skip frequencies needed, but if your installation has the need due to some
interference or harmonics due to the installation, it is available. These are also available in the VFD, but not quite as
detailed or adjustable.
6.13.10 VFD VIA COMMS (P13.31)

This enables A1000 drive control via Modbus. The analog output signal from X01 can also be monitored in P13.08, but
this signal is only used as needed for a VFD without this communications. Also reference Table 5.2 and Table 6.10.01.
The VFD speed is controlled by communications, and the drive communicates back to the Q1 the drive information. This
allows more information to be stored and communicated in the Q1. It also allows the analogue output to be utilized for
other things. Typically, we use output to communicate the oil temperature to the fan drive to control the temperature.
This is only available on the Yaskawa A1000 drive, which is the main one we use. This is the feature which gives
feedback on the operation, and in the event of a fault compressor fault, will record many operating parameters off the
drive to make it easy to relate operation with faults.

6.14 MOTOR PROTECTION (P14)
Motor protection is part of Q1’s Advanced Power Monitoring feature. Advanced power monitoring is provided in two ways.
First, frequency and phase protection is provided via the high voltage phase connection (X12). Secondly, phase angle,
under current detection, rotor lock overload and phase imbalance protection is provided. Combined, Advanced Power
Monitoring offers protection equivalent to Trip Class 10A for the main motor and fan motor overload protection equivalent
to Trip Class 10A, as well as current sensor and/or wiring error protection.
Main motor protection

P14.07 Fan MTR NOM CURR Amps 0.5 Fan motor nominal current (SFA)
P14.08 Fan MTR OVLD INH Sec 5 Fan motor overload inhibit time
6.14.01 Main MTR Protect (P14.01)

Turn on the main motor protection. This enables use of the CT’s to monitor the main motor current. When the VFD is
used, this is disabled as the VFD will supply its own protection. However, if we are not using the Yaskawa A1000 main
drive, we will turn this on and use CT’s to monitor the main motor current.
6.14.02 Fan MTR Protect (P14.02)

Turn on the fan motor protection. This enables use of the CT’s to monitor the fan motor current. On an updraft VFD, we
use a VFD to run the fan motor, and although the drive will give the fan motor protection, we use the CT to monitor the fan
current as added information in the event of a fault. It is turned on here, and set up on P14.07 and 08.
6.14.03 Main MTR NOM CUR (P14.03)

Current sensor or wiring error protection. If the measured current is lower than 20% of the nominal current (P14.03) when
the respective motor is running, the Q1 will assume there is a current sensor defect or that there is a wiring fault. Set
P14.03 to the service factor amps (SFA) of the main motor, or if it is a VFD, to the FLA. The default is 5.0A to force
configuration to the proper amp rating of the motor.
48
Overload protection characteristic:
Table 6.14.01
6.14.04 Main MTR SDTTF (P14.04)
Rotor lock and overload protection are never active simultaneously!
During a motor start, rotor lock protection is active for a factor of time determined by the star delta transition time factor
parameter at P14.04. Following the aforementioned period of time, rotor lock protection is deactivated and overload
protection is simultaneously activated.
6.14.05 Main MTR ROT LOC (P14.05)

Main motor rotor lock protection level (providing enhanced motor start event protection):
Rotor lock protection will immediately stop the main motor if the starting current is too high. The protection has a delay
time of 2 seconds to allow current peaks that occur when the main motor is initially started and / or during a main motor
wye-delta transition event. The following method is provided for guidance only! It can be used to establish a parameter
value for the main motor ROT lock parameter at menu P14.05. If in doubt, contact the factory engineers.
Table 6.14.02
49
The above chart illustrates with an 8 second Wye to delta transition time. Typical parameter values are between 4 and 7.
A simple method of establishing a parameter value is to gradually lower the parameter value until a main motor ROT lock
immediate stop event occurs. The motor should be COLD when using this method to establish a parameter value. Once
established, set the parameter value higher (for example... add 1.0) to compensate for performance variation due to
general wear and tear, filter blockages and lower compressor oil temperature. The values, once established and set here,
will be fine for the life of the compressor. If a change is needed, let us ask why, and work with this accordingly. More than
likely the issue is not the settings, but the operation.
Rotor lock and overload protection are never active simultaneously! During a motor start, rotor lock protection is active for
a factor of time determined by the star delta transition time and a factor parameter at P14.04. Following the period of time,
rotor lock protection is deactivated and overload protection is simultaneously activated.
6.14.06 Main MTR PH IMB (P14.06)

Main motor phase imbalance protection:
The value measured in each phase should be equal. Main motor phase imbalance measures any deviation in the phase
value of the incoming power on X12. If the measured value in any of the three phases deviates by more than the
configured value of P14.06 (configured as a percentage), an immediate stop event will occur.
Main motor phase angle protection:
No configuration is necessary! The Q1 monitors the sequential use of Phase 1, 2 and 3 (see P20.34 – P20.36) and the
corresponding phase angle.
L1 = 0°
L2 phase angle = 100° and 140°
L3 phase angle = 220° and 260°
If a phase angle error occurs and the immediate stop condition is configured, an immediate stop event will occur.
6.14.07 Fan motor protection (P14.07, 08)

The fan also has available CT’s for measuring the motor current and providing protection. In the event of a compressor
fault, the fan motor current is recorded in the fault log. The setup is the same as the main motor set up.
50
6.15 INHIBITS (P15)
The Q1 features configurable inhibits that restrict the compressor from starting or from running until they are cleared. They
will self-clear when the issue is resolved with no additional operator input needed. When cleared, the compressor will go
ahead and start on its own (run inhibit). These are not stored in the fault log.

Table 6.15, INHIBITS MENU (P15) OVERVIEW
6.15.01 OPERATOR (P15.01)

The operator inhibit is intended for operators to intentionally inhibit the compressor from operation. A digital input must be
assigned for this. This might be used in service shutdown when you want power but to prevent a remote start for example.
6.15.02 DOOR OPEN (P15.02)

Some rules require the device enclosure door(s) to be closed or no starting. To prevent running when the device
enclosure door(s) are open, the Door Open inhibit can be used to prevent the compressor from starting. The Door open
inhibit uses an assigned digital input. A digital input must be configured to ‘door open’ for the door open inhibit feature to
function. If a digital input has been assigned to ‘door open’ (see P18), then the door open inhibit can be used to prevent
the compressor from starting.
6.15.03 LOW TEMPERATURE (P15.03)

To prevent starting during extreme ambient conditions, the Low temperature inhibit is used to prevent the compressor
from starting. The “Oil Temperature” (AI3, P00.06) sensor value is used as a reference condition. This can be used with a
configured relay output to turn on a heater until the temperature rises to 2 degrees above the set point. It also alerts the
user that there may be ice in the lines, and thus pressure sensor readings may be off and unsafe to operate. If started, the
compressor will run when the temperature rises above the set point by 2 degrees.
6.15.04 SUMP PRESS HIGH (P15.04)

To prevent starting with excessive sump pressure, the SUMP PRESS high inhibit is used to prevent the compressor from
starting. The SUMP PRESS high inhibit uses the SUMP PRESS sensor (AI2, P00.08) value as a reference condition. If
started, the compressor will run whe the pressure falls below the set point.

6.16.01 SERVICE HOURS (P16.01-08)
Note that the service functions (‘Air filter SERV’, for example) are assigned to the individual service hours timers in menu
P11. If no service function is assigned in P11, the corresponding service hour parameter in menu P16 will be disabled.
These are countdown hours, and when service is performed, they need to reset for the next cycle. Experience will tell you
what this time should be for this function on this compressor.
6.16.02 SERVICE HOURS 2 Oil Service Life (P16.02)

The default service time for P16.02 (Oil service) is 4,000 hours, which is used for P-45 and food grade oil. P16.02 will be
set at the factory for other oils allowing a different service time: 8,000 hours for P-32 and 10,000 hours for Pal-Extra.
Experience will tell you if this is too long or not long enough.
6.16.03 SERVICE TIMERS (P16.09-11)

These timers are enabled in P11 and dates set here. These are interval service alarms, set for weekly, yearly or every 2
years. They can serve as a not for the customer doing his own normal service to have the distributor in annually or so to
check everything out.
6.16.04 DIFF PRESSURE (P16.15)

DIFF pressure is a calculated value (reference 6.2.09, P00.09). Must exceed set value for more than 10 seconds for
warning to occur. DIFF pressure warning monitoring is disabled when the temperature (COMP OUT TEMP, P00.06) is
below 50°C (122°F).

The separator differential pressure is a calculated value (reference 6.2.10, P00.10). Compressor pressure warning
monitoring is disabled when the temperature (COMP OUT TEMP, P00.06) is below 50°C (122°F).
00.10 00.09 42.05
known measured values of P00.08 and P00.07 (see 6.00.09) and the assumed pressure drop across the cooler as set in
P42.05. From the sump (P00.08), the air must take a path first through the separator, through the minimum pressure
valve, and then through the cooler to reach the outlet of the compressor (P00.07).
P42.05 is utilized whenever the outlet pressure (P00.07) reading is measured after the cooler (P2). For compressors with
a remote cooler (or if the outlet pressure P00.07 is measured at the Minimum Pressure Valve), P42.05 should be set to 0
variation in flow, and thus pressure drop.
6.16.06 PHASE DETECTION (P16.17)

The power source phase detection warning alarm is utilized for non-VFD compressors. If ‘ON’, this parameter will warn if
a loss of phase occurs or if the frequency is lower than 40Hz or greater than 70Hz for more than 500ms (or 25 cycles).
The phases are monitored on X12, the high voltage phase connection. Also see P17.11, SHUTDOWN FAULT. This is set
in test so that the phasing is correct throughout the system with no alarms if connected to the proper phasing. If a motor
has been disconnected, rotation and phasing needs to be verified again and corrected.

Table 6.17, IMM STOP ALARM MENU (P17) OVERVIEW
* Parameters P17.12 – P17.26 require a corresponding digital input assignment in menu P18 (see section 6.20).
** If ON, this parameter will immediately stop the compressor of a motor overload (determined by menu P14 configuration)
or if a main motor overload digital input registers a fault condition.
54
The shutdown faults are set very similarly to the alarms. These might need a similar digital input to be dedicated to the
fault, or a setting which is set higher than the corresponding alarm setting in P16.
Digital inputs can be used for either the shutdown fault, or the warning alarm. You can have both alarms and shutdown
faults with the same name, but each would need a separate digital input and separate contact to set each off. Digital
inputs are set up in P18, named function and normal state (Normally open or normally closed). Assignments is then made
for the shutdown fault here in P17.
Unlike our other microprocessors, raising the alarm set points will not raise the corresponding shutdown fault set point.
For example, if we set the shutdown faults for the sump pressure to 150 psi, and the alarm pressure at 140, the
serviceman can raise the alarm to 147 psi, but no higher. While we set the shutdown for what is safe, the serviceman
may want the alarm at a lower value to give a high warning earlier so action can be taken.
We allow a lower level of access for the alarms than we do for the shutdown faults so the serviceman can work with
these, but are limited by the shutdown faults. Because many companies do their own service, access to the service timers
and hence all the alarms in P16 would end up with the user.
The motor overload is set only as a shutdown fault. See the set up for this in P14 to set the levels for this. The shutdown
fault in P17 is only to turn it off and on, not to change the settings. The motor overload uses the CT’s for the current
readings. There is also a motor overload shutdown in many of our compressors using an overload off the contactor. This
is to DI8 and is a normally closed contact on the overload.

6.18 I/O CONFIG (P18)
The Q1 features a variety if input / output configuration options. Note: When configuring I/O assignments in menu P18, the
associated menu item(s) in the respective menus must also be configured. For example; if it is desired to configure digital
input 2 of menu item P18.02 for ‘Oil filter DP alarm monitoring’, the user must also enable the Oil filter DP alarm function
by navigating to the Oil filter DP alarm menu item at P16.19 and select ON. In summary, remember to enable a function
that is required and assign it to an input or an output.
The Q1 features one menu configurable Analogue output. Selectable options are tabled below.
Parameter Name Description
AO function Analogue output function. Press ENTER. Select from function list. Press ENTER.
OFF Feature disable
Delivery Press Outputs Equipment output pressure value via 4-20mA output signal

Fan Motor current Outputs Fan motor current value via 4-20mA output signal
Main Motor current Outputs Main motor current value via 4-20mA output signal
Table 18.01 Analogue output selections
The analogue output may be dedicated and not available in certain instances. One example is when in VFD mode and
not communicating via the Modbus communication. In this case the analogue output is taken for the speed output to the
VFD. It is unavailable for any other use.
Another case is an updraft VFD. The output of temperature is often used for the VFD fan temperature control. This is not
locked in, but is used by the compressor and selecting a different use will screw up the temperature control. The
temperature signal is 14-296 degrees Fahrenheit for 4-20 ma.
Other outputs are based on the range of the pressure transducers, or range of the current transducers.

P18.21 may be used to disable the sump pressure transducer if needed. We would only do that is the sensor is defective
and awaiting a replacement and you need to run. In this event, the blowdown time, P11.07 must be set up to about 60
seconds.
We use the KTY (rated 2000 ohms at 25 degrees C) temperature sensor for the oil temperature. It has a range of 14 to
296 degrees F. The PT100 and PT1000 have lower and higher temperature limits and would be used for other than oil
temperature.

Never change the pressure sensor without first verifying the range. We use 16 bar (232 psi) for our standard
compressors. A higher range will read much lower than the actual pressure, and will cause unsafe operation and safety
issues. You will think it is 125 psi when it really is over 200 psi. Always double check to match the range and configuration
of the Q1 to the sensor.

Connect current sensors in the following manner. CT1 and CT2 are for two phases of the power to the main motor. CT3 is
for one phase of the three phase power to the fan motor. These have different outputs and cannot be interchanged. When
facing the CT connector, terminal 1 is on the right. When installed in a Wye Delta configuration, each goes on a motor leg
directly. In the programming, it is specified if this is one part of a Wye Delta or a full current leg. CAUTION! Never
disconnect the CT when the compressor is running. If there is no drain for the induced power, these can explode! Always
work on a dead line, or take the measured leg out of the CT. We learn from experience!

6.21 RUN SCHEDULE (P21)
CAUTION! Be aware of this operation. The compressor can start from a stop
automatically with this feature turned on.
Stopping or removing power from the compressor will not stop this feature from restarting the
compressor from a dead stop or even from a power up condition when you walk away. This is
so different from the old pressure schedule.
The run schedule (also referred to as ‘pressure schedule’) provides an internal diary feature that schedules the
compressor controlled by the Q1 to start or stop, or run at a configured load and unload pressure at specified times on
specified days of the week, or, to just do something once and forget it. The run schedule achieves this by associating the
configured load and unload pressure values with the run schedule entry. Any changes made to a given schedule entry
must be saved with P21.XX.09 in order to take effect. It will also shut the compressor off and restart is when scheduled to
do so or simply put it in standby so it is ready to run. Stand by and scheduled off operate the same, but have different
legal implications.
The run schedule cycles through the settings on a weekly basis; beginning 00:00 hours on day of the week 1 (Monday)
through to 23:59 hours on day of the week 7 (Sunday). The day of the week and the time of day can be specified for each
setting along with desired load and unload pressure set points. The specified pressure set points from the set time and
day of the week will be used until the next chronological setting modifies the pressure set points, or the pressure schedule
is disabled or a remote override is activated. Different days and times may have different load and unload pressures,
individually set, or simply return to the default settings in P42.
The run schedule can be over road by closing the remote load contact without enabling it ( C6 to C+ by default). It cannot
be over road by simply shutting the compressor off, or stopping the compressor, it must be turned off either by a manual
over ride signal to C6 or by turning it off in P21.1. The schedule will keep working, and the next scheduled change will
take effect even if that is to turn on and run at a different pressure.
Temporary over rides are possible. For example, if you are scheduled to shut off on Friday evening, and not come back
on until Monday morning, you can override this if you come in on Saturday by pressing the start button. When done, press
the stop button. If there is a chance of this happening often, and people leaving with the compressor running, set a
second stop in the schedule for later in the day on Saturday when it should be off. This will assure someone doesn’t start
the compressor and leaves it on until Monday. Stopping the compressor will not prevent it from starting next scheduled
time. Also be aware the compressor will stop the next scheduled time, even if you need the air.
There are no limits to the number of settings that can be assigned to any particular day of the week, limited only by the 28
schedule point’s total. The Q1 will immediately operate in accordance with the schedule settings when the pressure
schedule is activated and the compressor is started. The pressure schedule entries need not be entered in the order
desired for it to operate. It will operate based on which scheduled event is next in time, not next in order in the schedule
entry. Any entry may be deleted or changed in any order. The schedule will automatically group and rearrange the events
chronologically for ease in troubleshooting and viewing.
Note: The pressure schedule will start and stop the compressor when scheduled, but, the compressor must be started
before pressure schedule functionality will operate. It will stop the compressor motor through the scheduled stop function.
The compressor will then be in a standby state, and will restart as needed. Use caution, as it can restart by itself as
scheduled with no prior warning!
The pressure schedule can be remotely suspended, and normal pressure set point control resumed, by activating the
remote load digital input (DI6 by default) without activating the remote load enable input. This can be used to temporarily
override the pressure schedule, with a single switch, during unexpected or non-routine periods, such as someone coming
in to work on a scheduled shut down or reduced pressure time. The ‘pressure schedule control’ symbol will flash during an
override situation. This will stop the action of starting and stopping automatically.
Pressing the STOP button will stop the compressor until the next scheduled change, and when stopped, pressing the start
button will start the compressor until the next scheduled change, but it will start up at the last scheduled pressure settings,
not the default settings.
In the event the schedule gets overwhelming, the total settings can be reset back to OFF and a new start to the schedule
can be made. In setting this up, it is helpful to write out a list of the settings you will want to make, and follow the list.
Stop means the compressor stops as though you pressed the stop button, and it will restart normally, Standby means it
will unload, run through the unload time, and go into stand by. It will start the same either way.

6.24.03 COOLING DP (P42.05)

known measured values of P00.08 and P00.07 (see 6.00.09). From the sump (P00.08), the air must take a path first
through the separator and then through the cooler to reach the outlet of the compressor (P00.07).
P10.08 is utilized whenever the outlet pressure (P00.07) reading is measured after the cooler. For compressors with a
remote cooler (or if the outlet pressure P00.07 is measured at the Minimum Pressure Valve), P10.08 should be set to 0
variation in flow, and thus pressure drop across the cooler..
6.24.04 X04 RS485 ADDRESS (P42.06)

X04 is set to Airbus485™’ which is the proprietary setting for all Metacenter sequencers, including the internal sequencing
of the Q1, T1 and S1 microprocessors we use.. The only variable in this configuration is the address. This address may
need to be set when this compressor is being used in any kind of sequencer application
65
6.24.05 START SOURCE (P42.07)
Start source is commonly associated with pressing the keypad ‘START’ button. In addition to the keypad ‘START’ button,
the Q1 features configurable alternatives for start source. In this menu, you may configure for ‘Keypad’, ‘Equipment DI’ or
‘Communications’.
Notes:
 Only the selected start source method is active. When selected, all alternative start source methods are inactive!
 Not listed as a start source is the RUN schedule. It will start the compressor as if the START button is pushed each
time it comes to a time to run the compressor. (See 6.21, RUN SCHEDULE)
 Any ‘start’ command merely signals the compressor to move to a started state. A compressor in a started state may
not necessarily start running (e.g. running, loaded). Inhibit functions, timers and the load source configuration will
continue to influence operating characteristics following a ‘START’ command.
 When configured for ‘keypad’ the keypad ‘START’ button functions as the start source. The keypad ‘STOP’ button
functions as the stop source (Normal operation).
 When configured for ‘Equipment DI’, digital input ‘is normally open, close to start, but this can be programmed to be
the opposite. Always, the state must be changed to stop or to restart if stopped by a fault or something else.
Carefully consider the characteristics of the digital input circuit during all operating conditions to determine the
appropriate ‘normal’ state.
 When configured for ‘Equipment DI’, an available digital input must be appropriately configured for ‘COMP start /
stop’. By default, DI 7 is so configured.
 When configured for ‘Communications’ an appropriate RS485 card must be configured for use.
 The local stop button continues to function as a stop. However, if stopped with the stop button. The digital input
must be cycled to the off position in order for it to function as the start again.
6.24.06 LOAD SOURCE (P42.08)

Compressor load source configuration. Select between ‘EQUIP OUT PRESS’, ‘Equipment DI’, or ’Communications’.
Notes:
 When configured for ‘Equipment DI’, Available digital inputs must be configured for Remote load enable and
Remote load / unload. By default, DI 5 and 6 are so configured
 Remote load enable purpose: Manages compressor master or local control. Can be used to return the
compressor to local if the remote load / unload signal is lost.
 Remote load / unload purpose: Loads the compressor from a remote signal. It allows the compressor to be
controlled by a plant management PLC. When unloaded, it will time out and shut the motor off regardless of the
compressor pressure.
 When configured for ‘Communications’ an appropriate RS485 option card must be installed and configured for
use. X04 is used for sequencing which is basically a remote load or unload signal, shut down by timing out the
unload run on time (P11.06). This must be so configured for any sequencing.
 Should the pressure rise to the pressure alarm set point, P16.13, it will unload regardless of the load signal from a
remote source.
6.24.07 LANGUAGE (P42.09)

This is where the default language for the user is set. We use USE, which is American (United States) English as

6.24.16 VFD TARGET PRESS (P42.18)

This is the discharge pressure the VFD will try to maintain by speeding up and slowing down as needed. It must be less
than the unload pressure by 3 psi, but other than that it is independently set. It can be over road by pressures set in the
run schedule or sequencing, or by external Metacenter sequencers. For these, their load setting or mid-range setting will
substitute for this target pressure.
6.24.17 P00.03, 04, 05 CONFIG (P42.22, 23, 24)

These are the user defined display of parameters on the P00 screen. They are inserted near the top of the P00 menu.
These display lines can be set to read any of the reading in the Q1. They can be turned off and just push the lower display
lines up, or set to anything you want the screen to show. We choose to use these in the VFD mode to show some of the
VFD operating parameters, and off in modulation.

6.25 ISC MAIN MENU (P80)
The ISC (Internal System Control) software is compatible with current and legacy controllers equipped with serial
communications and the Airbus485™ (formerly Multi485) field bus protocol. This includes our S1, T1, and P1 controllers
as well as the Q1.
In use, as demand for compressed air fluctuates and as system pressure decays or increases in response to that
demand, the ISC software ensures that network compressors are harnessed as one in order to obtain equilibrium where
efficiency, equipment utilization, and system pressure are in perfect balance. Compared to an unmanaged compressed air
systems with staggered pressures, that equilibrium represents a significant energy & cost saving opportunity. Each PSI of
pressure you can reduce the system will provide a half percent energy savings. The pressure control for all compressors
will be in the middle of the pressures set in this menu, and any VFD used in this system will control as a VFD no matter
how many compressors are called up to provide additional air.
The primary function of the ISC’s pressure control strategy is to maintain system pressure between the ‘High Pressure’
set point and the ‘Low Pressure’ set point in conjunction with targeting energy efficiency through optimal compressor
utilization. The ISC software calculates a ‘Target’ pressure level between the high and low pressure settings, which is
used as the nominal ‘target’ pressure level for all the compressors in the system, including VFD’s. Rate of change in
pressure, is largely determined by system volume and the scale, and/or abruptness, of air demand fluctuations. These
characteristics will differ from installation to installation. To accommodate for variations in installation characteristics, the
‘Tolerance’ pressure level (tP) and an influence on the dynamic reaction time (or ‘Damping’ (dA)) of the Q1 is adjustable.
The ISC (Internal System Control) option kit (eXternal Pressure Measurement) consists of a dedicated option card, AC /
DC power supply, and a remote pressure sensor. The kit is intended for use in compressor systems with up to 8
Airmaster™ equipped air compressors. The ISC option card is typically sold as an option in a separate enclosure and
connected with the compressor’s Q1 controller using Airbus485™ serial communications. The supplied pressure sensor
should be tubed to a suitable location (e.g. common air reservoir after any dryers or air handling equipment) where it will
sense the system common pressure. Once installed, the master air compressor’s ISC software feature can be configured
to provide narrow pressure band control of up to 8 Airmaster™ equipped and networked air compressors. With the Q1 as
master, all these features will be useful with any other compressor using the Q1, T1, S1 or P1 controller.
Contact the factory for more information on the ISC option kit and other Metacentre control options.

6.12.05 ISC AVAILABLE (P12.15)

Manufactures are able to offer the sequencer as a paid option. We chose to make it available to all. It can be disabled and
hidden and made available for a fee. All the sequencing set up need be in the master only, all the other slave units need
only be set to receive direction. (P07, AD and LS). All of our units have the ISC available so that any can be the master
controller. This menu is not available to anyone except the factory. This is for information only.
68
The below instructions all pertain to the master only. None of this is set or in any
way modified in the slave units. Leave these menus alone except for the master
6.25.01 ISC ENABLED (P80.01)

This sets up the sequencing in the Q1 as master controller. If ISC becomes unavailable for any reason, all the ISC
controlled compressors will revert back to local control. Thus the local settings are important to be set as well.
This turns the ISC on or off, and will turn on the ISC with auto restart capabilities in the event of a power failure. If the ISC
Master control is lost by a power failure while on, ISC will regain control of all ISC controlled compressors when power is
restored. While ISC is lost, local control will take over for the compressors which still have power until the master regains
power and control. For this to be effective the ISC must have the restart on and each compressor must also have the auto
restart turned on. If the ISC is not set for auto restart, it will not start after power failure unless manually restarted, even if
the auto restart starts the compressor back up.
6.25.02 LOAD AND UNLOAD PRESSURE (P80.02, 03)

This sets the load and unload limits for the entire set of sequenced compressors. It sets up to control in the middle of this
range, to set up the VFD to target this pressure if it knows there is a VFD in the mix. The compressors are not staggered,
but rather all work to maintain these limits. Because of this, we want to use the compressors at their best, and thus we
want to minimize the modulation, setting it on each compressor so it starts to modulate at just above the middle of this
range. This will provide the most efficient operation, and make sure that modulation does not restrict the compressors
from unloading and shutting down.
6.25.03 ROTATION INTERVAL (P80.04)

This sets the time one compressor will run lead before the sequencer makes a lead swap. It is adjustable between 1 hr.
and 720 Hrs. (1 month). When it is time to change; it will load the next compressor, and unload the running compressor.
Making a change in the time will not take effect until it has run out the clock on the first set up. To force a change, scroll to
the ISC screen, and press the RUN and ENTER buttons simultaneously. This will cause a manual rotation of lead and lag,
and start the new timing. This rotation will rotate only equally prioritized compressors. It will not change the priority set up.
In the set up, we can base load with a machine, or use one as a backup by setting priorities. These will not change.

Table 6.26, ISC SETTINGS MENU (P81) OVERVIEW
6.26.01 NUMBER OF COMPRESSORS (P81.01)

This is the number of compressors controlled by this master controller. They may be compressors with Q1’s, or legacy
controllers S1, T1, or the P1. Set for 2 to 8 compressors.
6.26.02 ISC START DELAY (P81.02)

Start delay time (staggered start function). When the ISC is started, compressors will be loaded, as required, with this
interval time between each load request. This feature is intended to prevent all compressors from starting and loading at
once during system start, or when one compressor is needed to be added to the system. In setting up a system, consider
reducing the load delay and increasing the start delay to gain good control of the system and prevent multiple
compressors from starting in a short period of time, build up pressure, and start unloading one after another. The use of
ISC Dampening and Tolerance will also help control the loading of the compressors in a timely and well controlled
manner. The start delay is adjustable between 0 and 120 seconds.
6.26.03 ISC DAMPING (P81.03)

6.26.04 ISC TOLERANCE (P81.04)
The ISC sequencing control reacts when the pressure falls outside the load/unload band. It calls up an additional
compressor, then another if the pressure is below the load set point, depending on how long it is below, and hot far it
drops. Same with unloading a compressor and letting it time out. The dampening and tolerance, along with to some extent
the start delay, can be adjusted to bring about a smooth control of the pressure without compressors coming on and off in
an inefficient manner. These setting are preset for an average system, and will work well out of the box, but may need to
be tweaked for your individual system to optimize operation.
The ISC’s dynamic reaction algorithm is pre-set by default to accommodate the majority of installation characteristics. In
some situations (see the following examples), the rate of pressure change may be aggressive and disproportionate:
a) Inadequate system volume
b) Excessive air treatment equipment pressure differential
c) Inadequately sized pipe work
d) Delayed compressor response
In such instances, the ISC may over-react and attempt to load an additional compressor that may not be necessary once
the initial compressor is running, loaded, and able to contribute adequate additional generation capacity. If an increase in
the ‘tolerance’ band is insufficient, the ISC’s dynamic reaction response can be influenced by increasing the ‘Damping’
factor (DA) reducing the tendency to over-react.
The ‘Damping’ factor is adjustable and scaled from 0.1 to 10 with a default factor of 3. A lower factor (.1) equates
70
to 10 times faster than a factor of 1, and a factor of 10 equates to 10 times slower than a factor of 1.
Tolerance is a pressure band above and below the set pressure control levels that accommodates for an exceptional
instance of abrupt and/or significant increase, or decrease, in demand without compromise to optimal control.
Figure 6.26.04, ISC TOLERANCE DIAGRAM
Tolerance (TO) is expressed as a pressure defining the width of the tolerance ‘band’. It has a range of setting from 3 to29
psi. A wider band slows the response to the pressure getting above the unload pressure, or below the load pressure.
For example: a tolerance setting of 3psi means the ISC will implement appropriate optimal response(s) during a deviation
of pressure 3psi below the set PL pressure level. If pressure ever deviates beyond the ‘tolerance’ limit the ISC will call on
additional compressors available until pressure is returned to normal levels. It will unload and shut off the additional
compressors as the pressure get above the unload pressure, taking into account the TO setting.
If system volume is inadequate, and/or demand fluctuations are significantly large, it is advisable to increase the
‘Tolerance’ band to maintain optimum control, and reduce over-reaction, during such transition periods.
If system volume is generous, rate of pressure change is slow and demand fluctuations are insignificant and gradual, the
‘Tolerance’ band can be reduced to optimize pressure control.
These are cumulative with added compressors.
71
XPM EXTERNAL PRESSURE MONITOR OPTION SET UP
We strongly recommend this option any time you plan on using this sequencing. It gives a cleaner pressure signal as the
controlling pressure. This pressure can come off the main receiver after any dryers, and other air handling equipment .
6.26.05 DIGITAL INPUTS IN THE XPM CARD (P81.05-P81.07)

In addition to providing a dedicated analogue input for connection of the remote pressure sensor, the Airmaster™ ISC option
card features 3 function selectable digital inputs.The function selections for the XPM unit’s digital inputs are:
0 = input has no defined function (unused)
1 = remote start stop. contact open = stop ISC. contact closes = start ISC
2 = remote alarm (normally open). contact closed = alarm
3 = remote alarm (normally closed). contact opens = alarm
4 = remote alarm (normally open). contact closed = alarm after 30 second delay
5 = remote alarm (normally closed). contact opens = alarm after 30 second delay
6 = remote trip (normally open). contact closed = trip,ISC function stop
7 = remote trip (normally closed). contact opens = trip, ISC function stop
8 = remote trip (normally open). contact closed = trip, ISC function stop after 30 second delay
9 = remote trip (normally closed). contact opens = trip, ISC function stop after 30 second delay
10 = sequence change (normally open). when contact changes from open to closed, force sequence change
We don’t generally use these functions.
6.26.06 XPM PRESSURE SETUP (P81.08)

This sets up the sensor for the XPM card. This sensor reads the pressure in the receiver tank for control instead of the
local discharge pressure reading of the master controller. Default is a 232 psi, 16 bar pressure transducer.
6.27 ISC PRIORITY (P82)

Set the desired priority for each compressor. Some of the uses might be to insure one is always the lead or always a
backup machine. A VFD could have priority 1, and as such it will trim all the others machines or it may be 2, and trim a
larger base load machine. Another use would be with different sized machines. This sequencer is not able to make use of
different sized compressors, but it can use a big one as the base load, add a VFD for trim, and then bring up machines
others as additional capacity as needed. This allows many ways to manage a compressor system without the precise
control of a Metacentre. Consult the factory for additional help.

7 SEQUENCING DETAILS
7.1 SEQUENCING OVERVIEW AND USE OF ISC CONTROLS
PURPOSE OF A SEQUENCER:
Many times an operating facility requires widely varying amounts of compressed air to run the plant satisfactorily with the
result that the facility is equipped with multiple air compressors in order to meet the air demand requirements and provide
back up for service. As companies have grown, they have added more air compressors to the mix, resulting in several air
compressors all trying to adequately service a plant efficiently. Given such a situation, it is often desired to even out the
running hours accumulated among all the compressors in the facility; especially if the compressors are of equal capacity.
For this purpose, sequencing may be implemented to help balance out the times. Also, through the use of the ISC settings
in P80-82, we can have a fairly robust management system for good efficiency and tight pressure control which will save a
substantial amount of energy, and money. This can incorporate a smaller VFD in conjunction with several smaller fixed
speed compressors to make a larger VFD in operation and savings.
SEQUENCER OPERATION PRINCIPLES:
Internal sequencing will work with up to eight compressors. The machines must be wired together with the RS485 data
link, X04 in a daisy chain fashion, not a spider hub. Polarity is important. L1 must connect to L1, and L2 must connect to
L2. Use shielded cable for the wiring between compressors. Ground one and only one side of the shield. Other
microprocessors (T1 and S1) use X07 as the data link for sequencing.
Sequencing involves a master/slave relationship. One compressor must be designated as the master, and all the others
will be slaves. This is set in the address for the units, and then in the settings of the master. The pressure setting used will
be the one found on the master controller in the ISC. Make sure this is a system pressure and is not shut off from the rest
of the compressors. If there is any question about the pressure readings being common to the whole system, (see below)
add an eXternal Pressure Module for a remote pressure indication and control. The slave compressors will have their own
alarms and safety shutdown controlled by their local pressure readings and settings. In the event of a failure of the master
control, shut off of power, or anything else, the compressors will revert back to local control and local settings.
Correct Installation Incorrect Installation
The above incorrect installation can be corrected to a superior installation through the use of the ISC remote pressure
module (XPM). This will allow accurate pressure control in cases where there are dryers and other pieces of equipment
between the compressors and the system, as in the “incorrect installation” above. It is installed on the pressure receiver
after all the auxiliary equipment.
If there is a VFD, it should serve as the master of the pressure but this is not necessary. A VFD should always have a
priority of 1, and other compressors 2 in order for it to function as a VFD no matter what additional units are called up. It
will run as needed to supply the needed air pressure, and it will call on the other slaves to run when needed. If there is
more than one slave, the master will determine which one is next up, and how many are needed to supply the right
amount of air to the plant. The master should be close to the same size or larger than the slaves so they don’t overpower
the master or VFD, or other priorities set properly.
Normally the VFD maintains tight pressure control at the VFD target pressure. In this case it will maintain the pressure
midway between the load and unload pressures. It will maintain this roughly with less precision, but will speed up or slow
down to maintain this pressure range. If it can’t keep up, it will call on the next slave up to help, and slow down to trim the
73
demand. When it has slowed to its minimum speed, and pressure continues to be above the unload pressure, it will send
the slave into unload and to sleep, and will speed up to maintain the pressure. Thus we see why the VFD should be a
larger compressor. If the demand drops to zero, the master will shut off too and sleep (stand by). We recommend in a
multiple compressor system that the VFD be sized one horsepower size above the other compressors.
PRACTICAL OPERATION:
The specific pressure needed should be noted. Even a small decrease in the control pressure will yield a savings in the
electric bill, 1% for every 2 psi pressure drop. The Master should be set up so the needed pressure is midway between
the load and unload settings. The VFD target pressure is set in P13.02 in the Q1. The slaves should have their modulation
regulator set so there is minimal modulation. The system will operate as efficiently as a VFD will, and thus it should not
modulate until it is right at the unload pressure. It will do a good job of maintaining the needed pressure, and so it does not
need to be set higher than needed. The master has PID control functions in it which will help to stabilize the control in
changing conditions.
The compressor’s run schedule will have no effect on the sequencer control, including, it will not make a pressure change,
or shut the compressor off in a time schedule nor will it turn on a compressor when scheduled to turn one on so it can go
back in the rotation. It will not do it. If it is turned off locally, it will have to be turned on locally to go back into the
sequencing. This kind of control can only come from other Metacenter products.
If a unit is designated as master, this does not mean that it will have priority in air production over the slaves unless it is
set that way. It will happily sequence between itself and the slaves as required in the sequencing scheme of things, but it
is the unit which will decide which compressor needs to load or unload, and also sends the appropriate commands to the
slaves to have the system operate as it should. Any unit can have any priority, and priority 1 will run all the time unless no
air is used. The VFD unit need not be priority 1 or the master, but can be fit anyplace into the scheme of things. See the
discussion in section 6.27 about priority set up. Consult the factory if additional help is needed.

Table 7.1, SEQUENCING SETUP TABLE
Please note that X04 is used with the sequencing. On the T1 and S1, X07 is used. Also, note that in the setup, X05 is
called the Airbus 486 Master, but this is used as the master to control the VFD, not the sequencing.
The compressors are wired together daisy chained from X04 to X04 or X07 (Legacy) or Metacenter, with polarity being
observed. They cannot be wired as a hub and spokes or a spider.
74
The symbol showing 3 files, ABC, will be on the top left of the screen, and will be solid if communication is good. If it is
flashing, check the wiring and the settings in each compressor.
Auto restart will restart the compressors, but not start up the sequencing unless the master is set to ‘ON RESTART’.
When using a Metacenter, there is an auto restart setting in them.
Each air compressor in the system must first be locally started; either running or in a standby state. The Master will not
start a Slave compressor that is in a stopped state. If the Master compressor experiences a fault condition that does not
disrupt successful controller operation or pressure detection, system regulation control and sequence management of the
remaining available Slave compressor(s) will continue uninterrupted.
Each compressor must be started locally with its own start button. The master will take control when the start button on
the master is pressed again in the ISC parameter, P00.16. When it takes control, it will unload as needed, and each
machine will shut down when the run on time has expired. It is recommended to start the master first, let the pressure
build up, then turn on the sequencing from the master, and then start the next compressors. If the master is keeping the
system pressure above the load set point, the other compressors will turn on but be unloaded and the motor will not start.
The green light on the front of an S1 or T1 will slowly flash, indicating it is in standby, the Q1 will say started or standby. If
everything is operating properly, the master will have an indication of the status of each slave.
Please note: sequencing is enabled by setting P80.01 (ISC enabled) to ‘ON’, but it will not begin until the ‘START’ button
on the Master compressor is pressed again while in menu P00.16. This is ONLY on the master unit, do not set this on any
slave, they will work fine when set up per instructions. A common error is to go into each compressor and turn on the
sequencing in P80, and that changes other parameters, so you can’t just go back and set it back to 0. If you make that
mistake, go back and set P80, EN to 0, and go into P42 and set the correct address for each slave again.
Load and unload settings (P80.02 & P80.03) are for the sequencer when it is controlling the system. Individual
compressors can keep their own settings to revert back to if the sequencing control is lost. Each compressor will use its
own readings for temperature and pressure to provide the compressor safety settings and functions.
When the sequencing is stopped using the stop sequence function in the master, P00.16, control will revert to the local
compressors and the local setting on each machine.
The ‘Status’ of each compressor is also indicated by the sequence display.
 If the letter is on continuously, it compressor is running loaded.
 If the letter is flashing slowly, the compressor is unloaded.
 If the letter is fast flashing, it is being called up to load.
 If the letter is replaced by a dash “-“, the compressor is not available, due to any number of conditions. Some of
these are: compressor not started locally, faulted out, communication or wiring issue.
A compressor is regarded as ‘not available’ if the RS485 data communications is interrupted, compressor has been
stopped, or in a fault state, and is unable to respond to a load request from the master.
The active ISC sequence assignment can be referenced in P00.16 on the master compressor.
A change in the sequence timing will not take effect until it has run its course and it changes sequence. That is, if it was
set to 168 hours, one week, and you change it to 24 hours, the new timing will not take effect until it has run through the
full168 hours. The compressors can be manually rotated in their sequence and this will put into effect the new sequence
schedule. To do this, press the run and the enter buttons simultaneously when in the compressor sequence status
indication on the master, P00.16. This will move each compressor up one position in the rotation, and start the new timing.
The XPM module is a separate piece of equipment, and is used where all the compressor outlets are not tied to a
common header. If there are dryers after each compressor, or it is desired to control the pressure in a vessel downstream
from the compressors, this is a needed item for proper operation. Please see sales for more information. It has its own
power supply and pressure transducer, and is tubed to the common header or tank, and needs 115 VAC to it, and is then
tied in the system as another item in the daisy chain of Modbus connections.
