and socket.
Check +VE supply from battery to starter motor.
Check -VE supply.
Check start terminal on Starter motor & trace back to battery via relay.
Check start terminal on Starter motor & trace back to module via relay, plug &
socket.
Ensure oil pressure switch or sensor is indicating the “low oil pressure” state
to the 3110 controller.
Fuel solenoid not
operating
Does the Fuel solenoid energise when the starter motor turns over.
Check Emergency stop.
Check the re-sets.
Check battery voltage is above 12.5V.
Check for loose wires on the solenoid, relays, fuses, module terminals, plug
and socket.
Check -VE supply.
Check +VE on Fuel solenoid & trace back to battery via relay.
Check +VE on Fuel solenoid & trace back to module via relay, plug & socket.
Continuous starting of
generator when in
AUTO
Check that there is no signal present on the “Remote Start” input.
Check configured polarity is correct.
Generator fails to start
on receipt of Remote
Start signal.
Check Start Delay timer has timed out. (Not configured on standard builds)
Check signal is on “Remote Start” input.
Confirm correct configuration of input is configured to be used as “Remote
Start”.
Check that the oil pressure switch or sensor is indicating low oil pressure to
the controller. The set will not start if oil pressure is not low.
Check for loose wires on charge alternator.
Check for loose wires on the DC connector plug and socket.
Check fuse. Fuse holder situated next to regulator in control panel.
Check continuity of all wires from charge regulator. (Refer to wiring diagram)
Check voltage at the battery while generator is running, voltage should be
13.4V - 14.4V.
Check AC voltage on green/white wires from engine voltage should be 38V.
Replace regulator.
Check fuel level is at 1/3 a tank minimum.
Check level switch operation normally closed with low fuel, opens when fuel
level ok.
Check connections on level switch.
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).
