The engine interface board is installed in slot #7. It consists of configurable inputs and
outputs. The configuration is done through the Qc4001 Utility Software and the default
settings can be changed to the relevant settings. To configure the inputs, upload the
parameter list from the Qc4001 and select the input to be configured. Then a configuration
dialog box appears and the settings can be changed.
The standard title (e.g. 4...20 mA in no. 2) can be changed and the new title will also be
shown in the display.
The minimum and maximum values of the 4...20 mA input can be adjusted:
- Value: Alarm value (e.g. 85°C)
- Min.: Value corresponding to 4 mA (e.g. 0°C)
- Max.: Value corresponding to 20 mA (e.g. 100°C)
The inverse proportional function is used when the input has inverse proportionality
according to the measured value.
The inputs can be used for a high or low alarm. As a “high alarm” the alarm appears when
the measured value is higher than the alarm limit, and as a “low alarm” the alarm appears
when the measured values are lower than the alarm limit.

7 Standard Modes
The Qc4001 is a protection and control unit for a generator driven by a diesel engine. It will
carry out all necessary tasks to control and protect a gen-set, regardless of the use of the
generator. This means that the Qc4001 can be used for several application types such as
described in chapter 10.
It is possible to operate the Qc4001 in three modes. The required mode can be selected via
a dedicated pushbutton.
The Qc4001 controls the gen-set and the circuit breakers (generator breaker GB and mains
breaker MB) automatically according to the operational state.
Manual control and activation of the sequences with the buttons on the LCDisplay.
The generator can be started/stopped manually.
The breakers can be closed/opened manually, but the module will check automatically
synchronizing sequences.

10 Application examples
10.1 Automatic Mains Failure application with Single gen-set installation and with Back-
syncronizing of the mains breaker MB
When the Qc4001 is operating in automatic mains failure operation, the following sequence
will be run through in a mains failure situation:
The mains failure must be present in the period “FAIL DELAY” before the MB is opened.
The timer “FAIL DELAY” will be reset each time when the mains is restored.
MAINS is MB GB is GB is GEN-SET
restored synchronises deloaded opened is stopped
The mains must have been present in the period “MAINS OK DELAY” before the MB
synchronises.
When the gen-set is running it will control the frequency and voltage to the nominal set
point.
When the Qc4001 is operating in peak shaving operation, the following sequence will be
run through when the generator is in standby and the imported load increases above the
configured limit:
When the load decreases below the stop gen-set limit, the following sequence is run
through:
MB load GEN-SET is
decreases deloaded GEN-SET is
below stop after time stopped
gen-set limit delay expires
When the gen-set is running it will be loaded between the minimum load limit (e.g. 5%) and

On the circuit diagrams you will find a terminal block (X25) where all the necessary
connections have to be made.
The circuit diagram for QAC gen-sets is 9822 0952 54.
Below you see a detail of circuit diagram 9822 0990 52 for QIX gen-sets. Depending on the
application the user has to connect the following wires:
- Mains sensing wires on X25.3 / X25.4 / X25.5
- Remote start signal on X25.9 / X25.10
- Mains breaker feedback wires on X25.11 / X25.12
- Mains breaker control wires on X25.13 / X25.14 / X25.15 / X25.16
- Mains power signal (from optional Power Transducer) on X25.21 / X25.22
- Active and reactive load sharing lines on X30.1 / X30.2 / X30.3 / X31.1 / X31.2 / X31.3
Important notes:
- Remove link between X25.10 / X25.11 when NOT running in Island Mode. The Qc4001
module always needs some feedback from the Mains Breaker MB. If you are in Island
mode, then there is no mains breaker in the system. In this case we simulate the ‘mains
breaker open’ signal with a bridge.
- Remove link between X25.17 / X25.19 for no droop operation. This is valid for the QIX
gen-sets with EMR control. In parallel operation with other gen-sets or with mains, you
need a frequency droop.

Even though screened cable is not needed, it is recommended if the cable run is longer
than 5 m between units.
Remark :
When the option PMS is installed these load sharing cables are not needed. The loads are
shared through the PMS communication cable.
The set-point inputs are passive, i.e. an external power source is needed. This can be an
active output from e.g. a PLC, or a potentiometer can be used.
The kWh counter (terminals 20-22) and kvarh counter (terminals 21-22) outputs are low-
power outputs.
A standard computer extension cable can be used (9-pole SUB-D male/female plugs) or a
cable can be tailored:
- Wires min. 0.22 mm²
- Max. cable length 6 m

This chapter shows the correct application configuration for the different use of the Qc4001.
The following application configurations are possible:
It is possible to use the Qc4001 for one of these purposes, or for peak shaving/fixed power/
load take over in combination with AMF.
The correct configuration can be set through the Qc4001 Utility Software or via the setup
menu on the LCDisplay.
From each of the above applications the module can jump into the Test mode , by pushing

When the mains goes outside the user-defined voltage (over and under) or frequency (over
and under) for a certain user-defined time, the mains will be disconnected and the gen-set
will be started to take over the load.
When the mains is restored within the user-defined limits for a certain user-defined time,
the gen-set will synchronise to the mains and deload the gen-set according a user defined
ramp before disconnecting the gen-set (only if back-synchronisation feature is enabled)
The gen-set will then go into cool down and stop.
The generator is running in a system with only short simultaneous connection to other

In combination with AUTO mode: The gen-set can be started/stopped with a remote start
command (= REMOTE START).
This can be a command through a signal from the internal real time clock.
This can be a command through a binary input. When an external hard-wired switch
(connected to this dedicated input) is closed, the unit will start up and the generator breaker
will be closed. When this external switch is opened again, the unit will open the generator

Warning:
By programming the parameters in AUTO mode, the generator can start up immediately. It
is recommended to place the generator in SEMI-AUTO mode while programming all the
PMS parameters !
In an application with PMS it is important to program correctly the Start & Stop signals
between the different generators because of the following reasons:
- The maximum load step needs to be programmed in the Qc4001 controllers. This never
may exceeds the power reserve of the running generators. Otherwise the gensets will go
in overload with a sudden max. load increase before the next generator is started up and
connected to the busbar.
- To prevent the gensets to run in a start – stop loop.
The start signal is the value of the maximum required load step
The stop signal is the value when the generator should be stopped automatically.
Example :
Installation with 3 gensets : G1 = 300 kW; G2 = 200 kW; G3 = 200 kW
Total Power needed > (Total available power of running gensets –setpoint start signal)
http://slidepdf.com/reader/full/user-manual-qc4001-manual 51/114
7/22/2019 User Manual Qc4001 Manual
- Stop signal is set at 100kW and priority is set as (high) G1 > G2 > G3 (low)
Stop signal if :
Total Power needed < (Total available power of running gensets – Power of generator
with lowest priority – setpoint stop signal)
G1&G2&G3 are running; at 400kW (700kW – 200kW –100kW) => G3 will be stopped
G1&G3 are running; at 200kW (500kW – 200kW – 100kW) => G2 will be stopped
The priority on starting & stopping the generators can be chosen on priority settings or on
the amount of running hours. In manual mode the start & stop sequence is determent by
the chosen priority between the generators. The generator with the lowest priority will start
as the latest genset and will stop as first. If running hours are chosen as priority the start &
stop sequence will be defined based on the actual running hours of the different
generators. The lowest running hours will get the highest priority.
Remark :
When paralleling generators with PMS, it is no longer necessary to use the analogue load
sharing lines. This will be done through the PMS communication lines. Use a screened
CAN communication cable with a maximum total distance of 200 meters. Do not connect
the cable screen to the ground ! Use a 120 Ohm resistor at both end controllers of the PMS
as described in the drawings below.

controller) :

7/22/2019 User Manual Qc4001 Manual
The connections for PMS between the generator and the Qc mains controller :
It is possible to communicate with the Qc4001 through the world wide web or local intranet.
To be able to use this feature, one Qc4001 must be installed with the optional TCP/IP
hardware, and all Qc4001 modules must be installed with the optional Can-bus
communication (standard when PMS option installed).
The communication with the world wide web is done through the TCP/IP unit.
This unit communicates through fieldbus with the other units in the system.
The web pages show the installation with the gen-sets, the breakers and the Qc4001 units.

If dynamic synchronisation is chosen, the next menu will be 2020. If static synchronisation
is chosen, the next menu will be 2030.
The setting of df max. and df min. decides whether the generator synchronises when
running faster or slower than nominal frequency.
The “dU max.” setting is related to nominal generator voltage. The “dU max.“ setting is +/-
nominal generator voltage.
The Qc4001 module compensates for the breaker delay time when synchronising.
The phase gain and frequency gain are the control parameters used during static
synchronisation. They both control the governor output.
The phase controller will keep the angle between the generator voltage and the busbar
voltage within the closing window. The frequency controller will keep the generator
frequency and the busbar frequency at the same value.

Settings are accepted limits (generator voltage and frequency) for closing the generator
breaker. The “dU max.” setting is related to nominal generator voltage.
If blackout closing of breaker is enabled on more units, external precautions must be taken
to avoid two or more generators closing on a black busbar. In that case synchronism will
not be present.
The Frequency KP and KI parameter are used for the speed settings on the genset.
The proportional controller (Kp) will have the effect of reducing the rise time and will reduce
,but never eliminate the steady-state error. The integral control (Ki) will have the effect of
eliminating the steady-state error. To have a quick and stable frequency both parameters

The mains power set point is the maximum imported power from the mains. If the load is
higher than this set point, the mains will supply the load equal to the mains power set point
and the gen-set will supply all additional loads.
It is possible to have two set points, daytime and nighttime set point. The purpose of this is
to adapt the mains import to the different load conditions in different periods.
The Qc4001 needs a 4...20mA signal on terminal 98-99 from an optional Power
Transducer, measuring the imported power from the mains. The calibration of the Power
Transducer must be:
- 4 mA = 0.0 MW
- 20 mA = Transducer scale, set-point in channel 3013.
The start / stop time of the daytime period are adjusted with hours and minutes. The period
outside the daytime period is defined as the night time period.
The set point is used to start the gen-set. When the imported mains power exceeds the set-
point in channel 3031, the gen-set is started and synchronised to the busbar. The set-point
in channel 3031 is referring to the mains power set-points in channel 3011 or 3012. The
start generator minimum load point is the minimum loading of the gen-set. The mains will
always supply the maximum possible power. The additional power will be supplied by the
gen-set.
http://slidepdf.com/reader/full/user-manual-qc4001-manual 87/114
7/22/2019 User Manual Qc4001 Manual
This set-point is used to stop the gen-set. When the imported mains power decreases
below the set point the stop sequence of the genset is commenced. The set point in
channel 3041 refers to the mains power set points in channel 3011 or 3012.
With the option PMS this is the setpoint for setting the maximum load step needed in the
application. The setpoint will tell you the minimal load step that always will be available by
the gensets.
The delay is the time before the next unit will be started.
The minimum load is the setpoint on which the generator wants to run minimally in a peak
shaving application.
With the option PMS the setpoint will give you the maximum power reserve before stopping
the gensets
The delay is the time before the last genset will be stopped.

Test sequence:
When the TEST mode is selected, the gen-set is automatically started and synchronised
with the mains. The sequence of the TEST is as follows:
Pushing the TEST pushbutton on the display activates the test mode. The TEST mode can
be used in peak shaving and AMF mode to check if the system is still functioning.
After the test run the Qc4001 returns to AUTO mode.
If the setting 3073 (Syncr.) is OFF, the sequence of the test is as follows:
17.3.8 Fixed power set-point (for active generator power and power factor)
The fixed power set points are used when the Qc4001 is configured to fixed power
operation. The PF (power factor) set point is used when the generator is running parallel to
mains.

These are parameters that needs to be programmed if the option PMS is installed.
Warning:
By turning this parameter to ON in AUTO mode, the generator can start immediately. It is
recommended to place the generator in SEMI-AUTO mode while programming the
parameters !
- Program the Qc4001 command controller in the application. If one controller is set to ON
the others will set automatically to OFF. Program the Qc4001 mains controller as
command unit if possible. The command unit communicates the following parameters to
the other connected units : start generator limit, start generator delay, stop generator limit,
stop generator delay, command unit, start & stop command, timer values.

The interruption deactivates the start relay, and a start failure alarm is displayed.
The GB ON sequence will synchronise and/or close the generator breaker. The breaker is
closed directly without synchronising if the mains breaker is open or if no mains breaker is
present (island mode), this means if the voltage on the busbar/mains is not present.
The GB ON sequence is automatically initiated (except in SEMI-AUTO mode) when the
automatic start sequence has been completed and the engine is running.
In SEMI-AUTO mode the operator may initiate the GB ON sequence by pressing the "GB"
pushbutton on the display.
- Running feedback from the engine (channel 4351, tacho configuration set-point or
running feedback input).
- The frequency and voltage has been present in the time “f/U OK” (channel 4381).

Stop sequence:
- Programmable cooling down time
- "STOP" output with programmable extended stop time
The stop sequence is carried out when the Qc4001 has completed the GB OFF sequence
and the generator breaker is open.
In AUTO mode the stop sequence is initiated automatically. In SEMI-AUTO mode a stop
command with the "STOP" pushbutton will stop the engine without cooling down. If the
generator is running with the generator breaker closed and the “STOP” pushbutton is
pressed, the generator is opened without deloading, and the engine is stopped without
cooling down.
A start command will interrupt an ongoing cool down period and leave the engine in idle
speed. A GB ON signal will synchronise and close the breaker.
A stop failure is displayed if the running feedback signal or the generator voltage and
frequency are still present.
If the coil type is configured as ‘running coil’, the stop coil will be energized during starting
and running and de-energized during stopping.

Mains failure:
Automatic mains failure is detected when the Qc4001 is in AUTO mode and configured as
an AMF unit. When the timer “FAIL DELAY” expires the following sequence is carried out:
- MB is opened
- Start sequence is initiated
- GB is closed
In case of MB open fail the sequence is stopped and an “MB OPEN FAILURE” alarm is
displayed.
When the mains returns the change-over sequence is started. The sequence is started
when the timer “MAINS OK DELAY” expires:
- MB is synchronised
- GB is de-loaded (if parallel running is allowed)
- GB is opened
- Stop sequence is initiated
In case of a sequence alarm the sequence will be stopped. If GB OFF fail and parallel
running is not allowed, then the MB is opened.
