SOFTWARE DIAGNOSTICS
Engine RUN State Shutdowns:
Engine RUN state is - DC circuit breaker on, generator successfully started and running
In the RUN state all shutdowns are logged and a light will be illuminated on the control panel. The generator will be
shut down and the light(s) will stay illuminated until the 12VDC power to the generator is cycled.
Oil Pressure shutdowns illuminate the OIL PRESSURE light.
Engine Coolant Temperature shutdowns illuminate the ENGINE TEMP light.
Exhaust Temperature High shutdown illuminates the EXHAUST TEMP light.
External Alarm shutdown illuminates the EXT. ALARM light.
OverSpeed and UnderSpeed shutdowns illuminate the pair of SPEED lights.
All other shutdowns illuminate
the pair of CHECK ENGINE lights.
