Operation
Changing Exercise Timers
If exercise timers or scheduled runs are needed, contact
a GMASD for assistance.
Shutting Down the Unit
Prior to shutting down the unit, check with personnel
using power supplied by the generator and let them know
the power is going to be turned off. Verify the power shut
down will not create any hazards by accidentally turning
off equipment that needs to be kept on (pumps,
compressors, lights, etc.).
1. Remove all loads from the generator by opening all
circuit breakers (turn OFF (O)).
2. Allow engine to run for approximately five minutes
to allow it to cool down.
3. Press the red engine STOP/RESET (O) button on
the controller. This will result in the generator going
into the shutdown cycle and starting a 15 second
shutdown timer. If the unit does not shut down
within 15 seconds, a stop fail alarm will be
displayed on the display screen.
4. After the unit shuts down, wait two minutes after
engine shutdown for controller actuated actions to
complete and then set the control power switch to
OFF (O).
NOTE: The ECU needs to run for 90 seconds after
shutdown to purge the DEF.
NOTE: Turning off the control panel before the controller
finishes updating could cause a loss of data.
NOTE: For extended storage time, disconnect the
battery. See the engine operator’s manual for extended
storage requirements.
Emergency Stop Switch
See Figure 3-12. The unit is equipped with one
emergency stop switch. The red button is clearly labeled
EMERGENCY STOP. The switch can be accessed and
activated with all doors closed and locked.
Figure 3-12. Emergency Stop Switch
Activate the emergency stop switch by pushing the
button in until it locks down. This trips the main circuit
breaker which then opens the contact, disconnecting the
load to the connection lugs. This will also open the fuel
circuit, shutting down the engine. The emergency stop
fault will be displayed on the control panel. The switch
will remain closed until it is pulled out.
Using the ECU Override Switch
IMPORTANT NOTE: Starting the engine with the
ECU override switch ON will not allow the engine to
shut down properly using the Engine STOP/RESET
Button. This must only be used when the engine is
OFF.
See Genset Controller for location of the ECU override
switch. This toggle switch powers up the ECU without
having to start the engine. Use the ECU override switch
to turn the ECU OFF. If the unit needs to be shut down
immediately, use the emergency stop switch. See
Emergency Stop Switch.
CAUTION
