Receiving:
Every effort is made to ensure that your GSC400 gen-set controller arrives at its
destination undamaged and ready for installation. The packaging is designed to protect
the GSC400 internal components as well as the enclosure. Care should be taken to
protect the equipment from impact at all times. Do not remove the protective packaging
until the equipment is at the installation site and ready to be installed.
When the GSC400 reaches its destination, the customer should inspect the shipping box
and controller for any signs of damage that may have occurred during transportation. Any
damage should be reported to a DynaGen representative after a thorough inspection has
been completed.
A shipping label affixed to the shipping box includes a variety of product and shipping
information, such as items and Customer numbers. Make certain that this information
matches your order information.
Each GSC400 controller is packaged in its own box. Do not discard the packing material
until the controller is ready for installation.
Handling:
As previously mentioned, each GSC400 gen-set controller is packaged in its own
individual box. Protect the equipment from impact at all times and do not carelessly
stack. Once the controller is at the installation site and ready to be installed, the
packaging material may be removed.
Storage:
Although well packaged, this equipment is not suitable for outdoor storage. If the
GSC400 is to be stored indoors for any period of time, it should be stored with its
protective packaging in place. Protect the controller at all times from excessive moisture,
dirty conditions, corrosive conditions, and other contaminants. It is strongly
recommended that the package-protected equipment be stored in a climate-controlled
environment of -20 to 65C (-4 to 149F), with a relative humidity of 80% or less. Do not
stack other equipment on top of the stored controllers.

The GSC400 also has a dedicated emergency stop input that when open will stop the
generator immediately and the controller will enter the OFF Mode (see below for more
information on the OFF Mode) and remain in the OFF Mode until the emergency stop
input is grounded. While the emergency stop input is active the GSC400 will sound an
audible alarm and display Emergency Stop on the LCD display. See Figure 4 on page
15 for the location of the emergency stop input.

While in Auto Mode the controller will display engine temperature, battery
voltage, fuel level, and engine hours.
3. RUN Mode The controller
starts the engine/generator and
enters the RUN Mode
automatically on certain triggers
(low battery voltage or to
exercise the generator) or the
user can manually start the
engine/generator by pressing the
Run key. Another option is to
use the remote start contacts
located on the digital input
connector. The controller will
automatically shut the
engine/generator down and re-enter the auto mode if it initiated an
engine/generator start. When the controller is in the OFF Mode automatic starting
is disabled.
When the controller is in the RUN Mode, generator parameters will be displayed
on the screen to allow the user to monitor the engine status. These include engine
speed, generator voltage and current, and engine temperature as well as others.
The parameters are displayed in groups and the screen scrolls between the various
groups. The Page Roll Display menu option controls how long each parameter
group is displayed on the screen before moving on to the next group. See Table 5
on page 30 for more information.
If an analog input is set to a Switch the GSC400 will display SW where
normally the value is displayed. If the analog input is set to J1939 or an Input Pin
then the actual value of the input will be displayed.

The GSC400 internal clock information can remain in memory for approximately 2
weeks when no DC power is supplied to the controller. Two week memory storage is
available in a completely charged controller clock. DC power is required to be supplied
continually to the GSC400 for approximately 1 hour to allow a complete clock charge.

The controller can be made to NOT sound the alarm when the controller is not in the
AUTO mode. This is controlled by the Not In Auto setting.
The OFF Mode Start setting can be set to Enable to allow a manual start from the OFF
mode. Otherwise a manual run can only be performed when the controller is in the
AUTO mode.

This section applies if J1939 is enabled for one or more parameters. The parameters will
be displayed the same for J1939 as they are for analog inputs. The only difference is that
when a certain parameter is not read from the J1939 bus the text N.A. is displayed in
place of the parameter value.
If the Loss of ECM setting is enabled the GSC400 will shut the generator down on Loss
of ECM if no communications are detected on the J1939 bus.

Failure Mode Indicator - The type of failure. You must refer to the engine
manufacturers documentation to identify the meaning of the failure mode
indicator number.
OC
Occurrence Count - Identifies the number of times the failure has occurred.
SPN
If one of these DTCs appears, please consult your engine manufacture for the definition
of this fault. With some engine manufacturers, the text of the message can also vary
slightly between engine types.
When active DTC messages are being received this will cause the controller display to
lock and display the messages. If multiple active DTCs are received the controller will
scroll and display each DTC message. The time between scrolling will be 3 seconds. The
DTC message display will look at follows.
41 of 105
Figure 8 Five active DTC messages and the 3rd one being displayed
The user can also manually cycle through the DTC messages by activating either the
"UP" or "DOWN" key after the screen has been locked. If the user stops at a specific
DTC message the display screen will remain on that message for a period of 10 seconds
before it begins scrolling again. Once the last DTC message is displayed, the display will
begin scrolling though other GSC400 parameters as normal. The DTC messages are no
longer available for viewing.

To Trigger a DM2 Request, simultaneously press the "UP" and "DOWN" keys for a
period of 3 seconds in either the AUTO, OFF, or RUNNING modes. The controllers
alarm will sound and the controller will send a request to the ECM. A LAMP test will
additionally be triggered in the OFF mode. The UP and DOWN keys can also be
pressed to remove the DM2 message screen.
If the GSC400 is in the OFF or AUTO mode when the request is triggered, the ECM may
not be powered on, so the controller will energize the fuel relay output and wait for the
ECM to power on. The GSC400 then sends out the DM2 request. In the event there is no
response from the ECM, the controller will re-attempt sending out the DM2 request an
additional 3 times every 1.25 seconds. It will then display "REQUESTING FAIL" and
turn off the fuel output if there is no valid response on the fourth try. The default ECM
address for DM2 request is 0 and the ECM address can only be changed from the
GSC400 PC interface. The GSC400 may also show "READING ABORT..." if
communication is unsuccessful. If the request was successful, the GSC400 will show
"READ DTC SUCCESS" and start to display the messages.

The GSC400 can display extra parameters for the engines listed in the Manufacturer
submenu. No warnings or failures can be generated with this data. To enable these
messages, go to the Display Group 1 and Display Group 2 submenus located in the
J1939 menu. If you have a different ECM manufacturer than listed under the
Manufacturer menu, the Display Groups 1 and 2 setting does not apply. Table 11 lists
the data parameters enabled for each group.

There is also a Loss of ECM submenu in the J1939 menu that you should enable if using
J1939. When enabled, the controller will shut down on a failure when certain J1939
messages have not been received on the CAN bus for 6 seconds.
Also, when there has been no data received for a specific parameter, that parameter
will display N/A in place of the value. This will disappear once data for the
parameter is received from the bus. This will also occur on startup until the GSC400
accesses the data from the bus. Note that loss of ECM may not be triggered since other
parameters may be receiving data from the bus.

ECM expects the speed update to be sent continuously and if it is not the ECM thinks
there is a problem with the J1939 communications.

Negative engine temperatures, can be displayed on the GSC400 but any reading below 00C (320F) is set to
0 C for warning and failure level detection purposes (e.g. low engine temperature, high engine
temperature).

** Some senders can be supplied by Dynagen. Refer to Table 22 Senders Part List on page
81 for the Dynagen stock code.
The six analog input pins are divided into two groups: those that support low resistance
senders and those that support high resistance senders. Low resistance senders have a
maximum resistance of less or equal to 500 Ohms. High resistance senders have a
maximum resistance of greater than 500 Ohms (usually they are a few kOhm).
Note that the senders listed in Table 12 cannot be used on all outputs (for the reasons
given in the previous paragraph). Table 12 also lists what sender tables may be loaded on
each input. If your sender is not supported or you wish to use a sender on an unsupported
input then you have to use the sender table configuration utility built into the PC Interface
that allows you to create new sender tables or to modify supported ones for the input you
desire. Refer to the PC Interface manual for more information.

6.4.1 AC Frequency
In the AC Frequency menu, warnings and failures can be triggered for frequencies under
and/or over settable thresholds. The DisconnectFreq setting is used by the GSC400
controller as a backup to the speed input. If the speed input is not detected, the controller
checks the DisconnectFreq settings. If the measured frequency is greater than this
setting then the engine will be considered running.
6.4.2 AC Voltage
The user can enter under voltage, over voltage, and over current settings for four different
voltage configurations. This allows the GSC400 to be used on multiple generator types
without having to configure each GSC400 or it allows a single generator to support
multiple voltage configurations without having to go into the menu system. Each voltage
group supports a different generator configuration:
1. Voltage Group 1 Single Phase (two or three wire)
2. Voltage Group 2 Three Phase (Delta or Hi Wye)
3. Voltage Group 3 Three Phase Hi Wye (Hi Wye centre tapped)
4. Voltage Group 4 Three Phase (three or four wire delta)
Voltage Group 1 has an option (the Group 1 Setting under the AC Voltage menu) for
two wire (Hot and Neutral) or three wire (A, B, Neutral) single phase. If two wire single
phase is selected the GSC400 display is fixed to L-N.
Voltage Group 2 can be used for 3 wire delta and non-center-tapped Hi Wye
configurations. Voltage Group 3 is the same as Voltage Group 2. There is a Group 3
Setting that can be enabled and is normally used for center tapped Hi Wye applications
where the voltage displayed on the controller is double the actual measured voltage.
Voltage Group 3 with the Group 3 Setting enabled is also useful in non-center-tapped Hi
Wye and 4-wire Delta applications where the user wishes to measure a voltage greater
than 600VAC the maximum voltage the GSC400 supports. In this case the user can use
a 2:1 potential transformer (PT) to step down the voltage to the GSC400 and still have the
GSC400 display the correct voltage.
Voltage Group 4 has an option (the Group 4 Setting submenu under the AC Voltage
menu) for four wire delta or three phases (default). The two different configurations are
shown in Figure 10. The three wire delta requires three voltage transformers to create the
neutral reference. For four-wire delta, Phase B must be connected to the stinger (high
LEG).
60 of 105
The GSC400 controller requires a neutral reference. All voltages are measured line to
neutral and then converted for display as line to line if required unless Voltage Group 1 is
selected with the two wire option in which case only Line to Neutral is displayed.

6.4.3 AC Current
The GSC400 controller is designed to measure AC current from the generator with the
use of current transformers (CTs). The maximum current on the AC current terminals of
the GSC400 is limited to 5A.
The Turns Ratio sub menu is used to setup the CT ratio. All numbers in this menu are
in terms of 5A. For example select 1000 means 1000:5A which, in turn, means the
GSC400 displays 1000A on the screen when the current measured on the GSC400 AC
Current terminals is 5A. The GSC400 current terminals can handle a maximum of
5A. Larger currents can damage the GSC400.
The AC Current menu is also used to set the over current warnings and shutdowns.
These are grouped in terms of the voltage group 1 to 4. The current warning and failure
depends on the voltage group selected in the Voltage Group submenu of the AC Voltage
menu.
The Hi Wye Current parameter (second to last entry in the AC Current menu) is used to
double the current reading (50% selection). If this is not desired then the 100% selection
should be selected. Some generators have two wires for each phase, and as such, the
current transformer (which is placed on one lead) will see only 50% of the current from
each phase.
The Cur Warn Latch option (last entry in the AC Current menu) is used to latch on a
special digital output (see Current Latch in Table 14 on page 64) that turns on when the
current exceeds the Current Warning Threshold and can only be turned off by the user
62 of 105
from the front panel. On a current latch condition the LCD displays Over Current
Latched. and <Up Arrow> + <Down Arrow> for Unlatch.
The current transformers (CTs) negative leads must be terminated individually into the
GSC400 AC Current connector. Do not tie the negative leads together to a common
neutral. See the system wiring diagram (Figure 4 on page 15) for more details.

Normally the fuel remains off in the AUTO mode until Preheat is entered. For electronic
engines some applications require that the ECM (which is powered by the Fuel Relay
output) to be powered in the AUTO mode in order to start the generator as quick as
possible. The J1939 menu has settings to allow the fuel output to come on in the AUTO
mode. See section 6.1.1 on page 52.
After the preheat (glow plug) time, the crank output is turned on for the duration
specified by the Crank Time. If the engine speed does not go above the Crank
Disconnect Setting before the crank time then the crank output is turned off and the
controller waits a period specified by the Crank Rest Time. The locked rotor condition
is also checked while cranking (see 6.5.1.1 Locked Rotor below). The fuel output is also
turned off unless the Fuel On During Crank Reset is enabled.
THE LCD WILL TURN OFF DURING THE FIRST 2 SECONDS OF
CRANKING TO LIMIT THE VOLTAGE DIP DURING CRANKING.
If the Midheat Time is greater than zero, the glow plug output remains on during
cranking but not during crank rest. The glow plug output turns off if a crank failure
occurs, once crank success is reached (unless the PostHeat is set to a value greater than
0s), or if the Midheat time expires.
After the crank rest delay expires, the controller turns on the fuel and crank outputs and
attempts to start the generator again. This is repeated until the number of tries equals the
Crank Attempts. If the controller cannot start the generator after the set number of
crank attempts, the failure state is entered and an over crank failure is displayed on the
screen.
If the generator starts successfully and the Restart on False Start submenu is set to
Enabled then the engine speed is monitored for 10 seconds. If the Off key is pressed
during these 10 seconds the engine will go into OFF mode without cooling down (if cool
down is enabled). If the engine speed goes below the crank disconnect speed the
controller attempts to restart the engine/generator. At the same time, if the Warm-up sub
menu is set to a value greater than zero, a digital output can be set to turn on (one of the
digital outputs or Extra relay must be set to Warm Up) when the warm-up is finished.
This is used to disengage any load or potential loads until the gen-set is warmed up.
During the Warm-up time the output remains off.
Once the controller enters the Running state and if the PostHeat time is greater than 0,
the glow plug output is turned on for the duration of the PostHeat time.

engine logic menu to 0. The Crank Oil Pressure is the oil pressure usually seen while the
engine is cranking.
During cranking if the oil pressure is below the Crank Oil Pressure parameter (engine
logic menu) and if the engine speed and AC frequency are both 0 the crank time is
shortened to 3s (including the time passed in cranking). If the engine/generator has not
reached the crank disconnect speed, frequency or the Crank Oil Pressure at the end of the
3s the GSC400 will stop cranking and go into a Locked Rotor Failure.
This feature prevents damage to the generator if for something is preventing the engine
crankshaft (or generator rotor since it is connected to the crankshaft) from rotating.
Cool Down
Over Crank
Description
This sets up the output to be controlled by the Warm-up feature.
See section 6.5.1 for more details. The Warm-up time is set in the
engine logic menu. This is an active low output (i.e. the output
remains off during warm-up and turns on after warm-up is
finished). The output always remains off when the controller is
not in the RUN mode.
This allows the Energize to Stop feature to control an output. The
time duration is set in the engine logic menu. See section 6.5.2 for
more details.
This allows the Preheat, Midheat, and Postheat features in the
engine logic menu to control the output. The Preheat (glow plug)
time is set in the engine logic menu. See section 6.5.1 for more
details.
This allows the Cool Down feature to control the output. The
Cool Down duration is set in the engine logic menu. See section
6.5.2 for more details.
This turns on the digital output when the Over Crank Failure is

The GSC400 will display a message and sound the buzzer for a set amount of time (PreAlarm Delay) to alert nearby personnel that the generator is about to start. The
engine/generator will run for a set period of time (Run Duration) and then shut down.
The Start Date and Start Hour determine the date (0 to 31) and time when the
engine/generator will first start. After the first exerciser start, the engine/generator will
start up on regular intervals given by the Repeat Freq which is measured in hours.
The exerciser feature depends on the GSC400 internal clock. Make sure the clock is set
to the proper time and date.
GSC400 internal clock information can remain in memory for approximately 2 weeks
when no DC power is supplied to the controller. Two week memory storage is available
in a completely charged controller clock. DC power is required to be supplied continually
to the GSC400 for approximately 1 hour to allow for a completely charged clock.
The remote start contacts (RSC) are ignored in an exerciser started run until the
GSC400 enters cool-down or AUTO. To prevent the engine from shutting down set the
cool-down time to a value other than 0. While in cool-down the GSC400 will detect the
RSC and will go back into the RUN mode without shutting down.

modes.
This input generates a Low Oil Pressure failure when active
only when the controller is in the RUN mode.
If the generator is starting up but is not running (i.e. the controller
is not in the RUN Mode) and if the input is active, the GSC400
will cancel the start sequence and enter the failure state on an EPS
load failure.
After crank success, if the input is active, the EPS Supplying
Load lamp on the GSC400 front face will turn on.
This input silences the buzzer on the GSC400 unit when active.
This input generates a Low Coolant Level failure when active.
These inputs allow the user to change the supported generator
configuration without having to go into the controller menu. See
section 6.4.2.1 for more details.
This input, when active, allows the generator to run at a lower
speed without triggering under-voltage, under-frequency, or
under-speed warnings or failures. Idle Running is displayed on
the GSC400 display when this input is active. See section 5.5 on
page 25 for more information on the Idle Mode feature.
The idle mode can also turn on a digital output (see the Voltage
Regulator digital output feature in Table 14 on page 64). This
output is usually used to turn off the generator voltage regulator
when idle mode is entered but can be used for any purpose.

This is also used for Cummins J1939 Idle Feature. See section
5.12.1 on page 39 for more information.
When the digital input is active the generator is started if in the
Auto mode. If the digital input becomes inactive this places the
controller back into the Auto mode (shuts down the generator).
This performs the same function as the remote start contacts.
An Auxiliary Failure is generated when the input is active. This
can occur in the Off, Auto, Cranking, and Running states.
An Auxiliary Warning is generated when the input is active. This
can occur in the Off, Auto, Cranking, and Running states.
A Charger 1 Fault warning is generated when the input is active.
A Charger 2 Fault warning is generated when the input is active.
A High Fuel Level Warning is generated when the input is
active.
These inputs when active generate a warning/failure and a
configurable text message is displayed to the screen when the
input is active. The text message can only be configured from the
GSC400 PC Interface. The length of the message is limited to 15
characters.
The user can control the states in which these features are
enabled. The selections are:

The controller will check the log request every 1 second. Each time a new command is received, the
controller will scroll either down or up one message (until it reaches either the bottom or top of the
message log), one message and update the log content in address 40131 to 40141. Once at the top of
the log, registers 40131 to 40141 are not changed if a Read Previous Entry command is received.
Once at the bottom of the log, registers 40131 to 40141 are not changed if a Read Next Entry
command is received. After 20s of receiving further commands in register 40130, all registers are
cleared (i.e. set to 0).
