  • Warning (WRN) WRN
  • Sensor fail (FLS) SD
  • OVERSPEED OR UNDERSPEED SHUT DOWN
    Cause: Engine speed is above or below 60.0 Hz.
    Fix: Disconnect all loads and restart the generator to read frequency (Hz). Adjust engine speed as necessary.
  • OVERCRANK SHUT DOWN
    Cause: Engine will not start.
    Fix: Check fuel level in tank and proper operation of the fuel pump. Check air filter for blockage.
  • LOW OIL PRESSURE SHUT DOWN
    Cause: Engine oil pressure is less than 20 psi (138 kPa).
    Fix: Check engine oil level and add oil if required. Visually inspect the engine for oil leaks.
  • LOW FUEL LEVEL SHUT DOWN
    Cause: Fuel level on the Liquid Crystal Display (LCD) window is low or fuel tank has leaks.
    Fix: Check the fuel level and ensure it is not running dry. Check for leaks in the fuel tank.
  • LOW COOLANT LEVEL SHUT DOWN
    Cause: Coolant level in the radiator is low or coolant lines have visible leaks.
    Fix: Check the coolant level and add coolant if necessary. Inspect for leaks in coolant hoses, engine block, and water pump.
  • HIGH COOLANT TEMPERATURE SHUT DOWN
    Cause: Coolant temperature is 230°F (110°C) or more.
    Fix: Check coolant level in the overflow jug and add coolant if necessary. Inspect radiator, coolant hoses, engine block, water pump for leaks. Check serpentine drive belt tension.
