Common problems

11
  • Engine down 000192
  • Alarms, warnings, and engine Diagnostic Trouble Code (DTC) faults are displayed.
    Fix: When an alarm occurs, the controller automatically switches to this screen and remains there until the alarm is cleared. The Stop LED also flashes.
  • Unit cranks but does not start
    Cause: Fuel level low
    Fix: Check fuel level in tank. Verify fuel pump operation.
  • Restricted air filter
    Fix: Inspect air filter for blockage.
  • Overspeed or underspeed shutdown
    Cause: Frequency setting incorrect
    Fix: Disconnect all loads and restart unit. Read frequency (Hz) in the LCD window on controller. Frequency should read 60 Hz. If frequency is above 60 Hz, engine speed will need to be adjusted. Refer to the engine operator’s manual for throttle adjustment information.

  • Leakage in coolant hoses, engine block, or water pump
    Fix: Inspect for visible leaks. Verify tension of water pump serpentine drive belt.
  • High coolant temperature shutdown
    Cause: Low coolant level
    Fix: Add coolant if needed. Allow engine to cool, then check coolant level in radiator. Restart engine and check coolant temperature. Stop engine immediately if coolant temperature is 210°F (99°C) or more.
