Volts
Check the operating temperature is not above 70 °C.
Check the DC fuse.
Unit locks out on Emergency Stop If an Emergency Stop Switch is not fitted, ensure that a
positive 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

Low oil Pressure fault operates after
engine has fired
Check engine oil pressure. Check oil pressure
switch/sender and wiring. Check configured polarity (if
applicable) is correct (i.e. Normally Open or Normally
Closed) or that sender is compatible with the 560 Module
and is correctly configured.
High engine temperature fault
operates after engine has fired.
Check engine temperature. Check switch/sender and
wiring. Check configured polarity (if applicable) is correct
(i.e. Normally Open or Normally Closed) or that sender is

Check battery supply is present on the Starter output of
module. Ensure that the Emergency Stop input is at +Ve.
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.
Incorrect reading on Engine gauges Check engine is operating correctly. Check sender and
wiring paying particular attention to the wiring to terminal 24
(refer to appendix). Check that sender is compatible with
the 560 Module and is correctly configured.
