Part No. 057-086 3000 Series OPERATING MANUAL ISSUE 4 03/12/2009 ADM 35
11 FAULT FINDING
SYMPTOM POSSIBLE REMEDY
Unit is inoperative
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.
Unit locks out on Emergency Stop If no Emergency Stop Switch is fitted, ensure that a DC positive signal is
connected to the Emergency Stop input. Check emergency stop switch is
functioning correctly. Check Wiring is not open circuit.
Intermittent Magnetic Pick-up
sensor fault Ensure that Magnetic pick-up screen only connects to earth at one end, if
connected at both ends, this enables the screen to act as an aerial and will
pick up random voltages. Check pickup is correct distance from the flywheel
teeth.
Low oil Pressure fault operates
after engine has fired Check engine oil pressure. Check oil pressure switch/sensor and wiring.
Check configured polarity (if applicable) is correct (i.e. Normally Open or
Normally Closed) or that sensor is compatible with the 3310 Module and is
correctly configured.
High engine temperature fault
operates after engine has fired. Check engine temperature. Check switch/sensor and wiring. Check configured
polarity (if applicable) is correct (i.e. Normally Open or Normally Closed) or that
sensor is compatible with the 3000 series module.
Shutdown fault operates Check relevant switch and wiring of fault indicated on LCD display. Check
configuration of input.
Warning fault operates Check relevant switch and wiring of fault indicated on LCD display. Check
configuration of input.
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 3000 series module inputs. Refer to engine manual.
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.
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. Depending upon configuration, the set will not start if oil pressure is
not low.
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 that the Emergency Stop input
is at Positive. Ensure oil pressure switch or sensor is indicating the “low oil
pressure” state to the 3000 series controller.
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
remote start on load signal.
