11.3 ALARMS
SYMPTOM POSSIBLE REMEDY
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 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 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.

CAN ECU SHUTDOWN
This indicates a fault condition detected by the engine ECU and
transmitted to the DSE controller.
Press the RIGHT ARROW button to view the engine diagnostic code
and consult the engine manufacturer’s documentation.
CAN DATA FAIL Indicates failure of the CAN data link to the engine ECU.
Check all wiring and termination resistors (if required).
Check the ECU OVERRIDE function detailed in the section entitlted
OPERATION elsewhere in this manual.
Incorrect reading on Engine
gauges
Fail to stop alarm when
engine is at rest
