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 6000 series controller.
Engine runs but
generator will not take
load
Check MCB is switched on.
Check change over switch if fitted is switched to correct voltage.
Fail to stop alarm when
engine is at rest
Check low oil pressure switch is operating correctly.
Check engine is operating correctly.
Module appears to
‘revert’ to an
earlier configuration
When editing a configuration using the PC software it is vital that the
configuration is first ‘read’ from the controller before editing it. This edited
configuration must then be “written” back to the controller for the changes to
take effect.
When editing a configuration using the Front Panel Editor, be sure to press
the
Save button to save the change before moving to another item or
exiting the Front Panel Editor.
Inaccurate generator
measurements on
controller display
The 3110 controller is true RMS measuring so gives more accurate display
when compared with an ‘average’ meter such as an analogue panel meter or
some lower specified digital multimeters.
Accuracy of the controller is better than 1% of full scale. Ie Gen volts full
scale is 333V ph-n so accuracy is ±3.33V (1% of 333V).

6.11 Fault finding general
High engine
temperature
Check Water/Antifreeze level in the radiator.
Check for loose wires on the temperature switch & DC loom connector block.
Check the continuity of the earth wire. (Refer to wiring diagram)
Check radiator surface (both sides) and fins are not obstructed.
Check operation of the Temperature switch.
Check that the generator air inlets and outlets are not obstructed.
Check the fan belt is not damaged, broken or loose. (Refer to handbook)
Note
you may experience low charge if fan belt is loose.
Low oil
pressure
Check Oil level and fill to correct level if necessary
Check for loose wires on the Oil switch & DC loom connector block.
Check the continuity of the earth wire. (Refer to wiring diagram)
Check operation of Oil switch.
HZ / Frequency
shutdown &
Voltage
shutdown
Check engine has been regularly or due a service. (fuel filters especially, poor engine
performance effects the overall output voltage)
Check reset button has not tripped and reset if required.
Check AC Input at module. 115V or 230V (Dependant on type of generator)
Check engine speed is set to 52.5Hz at no load.
Check AC supply from alternator. (If no output refer to alternator handbook)
Check capacitor and replace if necessary.
Check fuse on AVR, check AVR. (if fitted and replace if necessary)
No power to
control module
Check reset button has not tripped and reset if required.
Check 12V DC supply to module. If supply present but not operational try new unit.
Check battery voltage. (should be around 12.6 V DC)
Check battery isolator switch is on.
Check for loose wires on battery isolator.
Check for loose wires on the DC connector plug and socket.
Check continuity on +VE and -VE wires to battery.
