Read/Write configuration
does not operate
Check the battery and wiring to the unit. Check the DC supply.
Check the DC fuse.
Unit shuts down
Check DC supply voltage is not above 35 Volts or below 9 Volts
Check the operating temperature is not above 70°C. Check the DC
fuse.
Fail to Start is activated after
pre-set number of attempts to
start
Check wiring of fuel solenoid. Check fuel. Check battery supply.
Check battery supply is present on the Fuel output of the module.
Check the speed-sensing signal is present on the module’s inputs.
Refer to engine manual.
Continuous starting of
generator when in the
Auto Mode
Check that there is no signal present on the “Remote Start” input.
Check configured polarity is correct.
Check the mains supply is available and within configured limits

Pre-heat inoperative
Check wiring to engine heater plugs. Check battery supply. Check
battery supply is present on the Pre-heat output of module. Check
pre-heat configuration is correct.
Starter motor inoperative
Check wiring to starter solenoid. Check battery supply. Check battery
supply is present on the Starter output of module. Ensure oil
pressure switch or sensor is indicating the “low oil pressure” state to
the controller.
9.2 LOADING
Symptom
Possible Remedy
Engine runs but generator will
not take load
Check Warm up timer has timed out.
Ensure generator load inhibit signal is not present on the module
inputs.
Check connections to the switching device.
Note that the set will not take load in manual mode unless there is an
active load signal.
