Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| WrnMaintenance (Time to Service reminder displayed) | Unit is due for maintenance or service (250 hour interval) | Reset the running hours to 250: with the unit shut down, power up the controller with the Control On/Off toggle switch; press PAGE SELECT; press the down button to move the > cursor to Engine Protect; press ENTER; press ENTER again; press the up button and reset the current run time hour setting to 250; press ENTER to save; move the CONTROL ON/I toggle switch to the CONTROL OFF/O position |
| Low fuel level shutdown | Fuel level low (engine controller shuts the engine down when there is 5% of fuel remaining in the tank) | Check the fuel level on the LCD window and confirm the generator is sitting level to ensure an accurate reading |
| Low fuel level shutdown | Leaks in the fuel tank | Check for leaks in the fuel tank; the fuel tank should not run dry under normal circumstances |
| Low fuel level shutdown | Fuel level sender and connecting wiring damaged | Check the fuel level sender and the connecting wiring for damage; to check for continuity between the sender and the engine controller, remove the appropriate bolts from the control panel to access the inside of the control box and consult the DC wiring diagram for the proper path between the engine controller and the fuel level sender |
| Low oil pressure shutdown | Low engine oil level (engine controller shuts the engine down when the oil pressure is less than 20 psi (138kPa)) | Check the level of the engine oil with the dipstick; add oil if required |
| Low oil pressure shutdown | Oil leaks | Visually inspect the engine for oil leaks |
| Low oil pressure shutdown | Loss of oil pressure | If the oil level is good, restart the unit and verify the loss of oil pressure; shut the engine down immediately if the oil pressure value does not read 5 psi (34kPa) within 5 seconds |
| Low oil pressure shutdown | Oil pressure sender | Check the oil pressure sender; to identify corrective action, refer to the troubleshooting section of the engine operator's manual provided with the unit |
| Low coolant level shutdown | Low coolant level | Allow the engine to cool and confirm the unit is sitting level to ensure an accurate reading; check the coolant level in the radiator (remove the access panel from the top of the enclosure directly above the radiator to access the radiator cap) and add coolant until it is 3/4 in. (1.9 cm) below the filler neck; secure the radiator cap back into its original position |
| Low coolant level shutdown | Visible leaks | Inspect coolant hoses, engine block and water pump for visible leaks |
| Low coolant level shutdown | Coolant mixed with engine oil | Check the engine oil to verify no coolant has mixed with it (oil will appear milky if coolant is present); consult the engine operator's manual for additional information |
| High coolant temperature shutdown | Low coolant level in the overflow jug | Check the coolant level in the overflow jug; allow the engine to cool, add coolant to the overflow jug if it is low and then check the level of coolant in the radiator (remove the access panel from the top of the enclosure directly above the radiator to access the radiator cap) and add coolant until it is 3/4 in. (1.9 cm) below the filler neck; secure the radiator cap back into its original position |
| High coolant temperature shutdown | High coolant temperature | Restart the engine and read the coolant temperature to verify a high coolant temperature shutdown; stop the engine immediately if the coolant temperature is 230°F (110°C) or more |
| High coolant temperature shutdown | Radiator shroud and ducting blockage | Check the radiator shroud and ducting for blockage and remove any foreign matter |
| High coolant temperature shutdown | Visible leaks | Inspect coolant hoses, engine block and water pump for visible leaks |
| High coolant temperature shutdown | Serpentine drive belt for the water pump tension | Check the tension of the serpentine drive belt for the water pump |
| High coolant temperature shutdown | Engine overheating | If no other problems are found, remove the load on the generator and restart the engine; check the coolant temperature and shut the engine down immediately if it starts to overheat; consult the engine operator's manual for additional information on engine overheating |
| Overcrank shutdown | Fuel level in the tank | Check the fuel level in the tank |
| Overcrank shutdown | Improper operation of the fuel pump | Check for proper operation of the fuel pump |
| Overcrank shutdown | Air filter blockage | Check the air filter for blockage |
| Overcrank shutdown | Engine will not start | If the engine will not start, consult the engine operator's manual for additional information on troubleshooting starting problems |
| Overspeed or underspeed shutdown | Frequency above or below 60.0 Hz (engine speed incorrect) | Disconnect all loads and restart the generator; read the frequency (Hz) on the LCD display (with no loads on the generator, the frequency should read 60.0 Hz); if the frequency is above or below 60.0 Hz, the engine speed will have to be adjusted — refer to the engine operator's manual for throttle adjustments on mechanical governed units and see the electronic governor manual for electronically controlled units |
