| 17 | Overload — The load is greater than the value given by Overload setpoint. | ||
| 18 | Overspeed — The protection comes active if the speed is greater than Overspeed setpoint. | ||
| 19 | ParamFail — Wrong checksum of parameters. Happens typically after downloading new firmware or changing of the parameter. The controller stays in INIT mode. | Wrong checksum of parameters | Check all parameters, write at least one new parameter. |
| 20 | PickupFault — Failure of the magnetic pick up sensor for speed measurement. | ||
| 21 | Sd IOM fail — Shutdown alarm in case of lost connection to IOM/IGS-PTM module. | ||
| 22 | SprinkIActive — The protection is active if the output Sprinkler is closed. | ||
| 23 | Start failed — Unit did not start. | ||
| 24 | Stop fail — Unit did not stop. | ||
| 25 | Ubat — Battery voltage is out of limits given by Batt Undervolt setpoints. | ||
| 26 | Underspeed — During starting of the engine, when the RPM reaches the value of Starting RPM setpoint, the starter is switched off and the speed of the engine can drop under Start RPM again. Then the Underspeed protection becomes active. Protection evaluation starts 5 seconds after startup. | ||
| 27 | Vgen<, > — The generator voltage is out of limits given by Gen <V and Gen <V setpoints. | ||
| 28 | Vgen unbal — The generator voltage is unbalanced more than the value of Volt unbal setpoint. | ||
| 29 | Wrn ECU Alarm — ECU alarm list is not empty. | ||
| 30 | Wrn RA15 fail — Warning alarm in case of lost connection to IGL=RA15 module. | ||
| 31 | WrnMaintenance — The period for servicing is set by the WrnMaintenance setpoint. The protection comes active if the running hours of the engine reach this value. | ||

| Symptom | Cause | Remedy |
|---|---|---|
| Low fuel level shutdown | Fuel level low; Leaks in the fuel tank; Fuel level sender or connecting wiring damaged | Check the fuel level on the LCD window and confirm the generator is sitting level; Check for leaks in the fuel tank; Check the fuel level sender and the connecting wiring for damage and check for continuity between the sender and the engine controller |
| Low oil pressure shutdown | Low engine oil level; Oil leaks; Loss of oil pressure; Faulty oil sender | Check the level of the engine oil with the dipstick and add oil if required; Visually inspect the engine for oil leaks; Restart the unit and verify the loss of oil pressure, shutting the engine down immediately if the oil pressure value does not read 5 psi (34 kPa) within five seconds; Check the oil sender and refer to the troubleshooting section of the engine operator's manual |
| Low coolant level shutdown | Low coolant level; Leaks in coolant hoses, engine block or water pump; Coolant mixed with engine oil | Allow the engine to cool; Check the coolant level in the radiator and add coolant until it is 3/4 in. (1.9 cm) below the filler neck; Inspect coolant hoses, engine block and water pump for visible leaks; Check the engine oil to verify no coolant has mixed with it |
| High coolant temperature shutdown | Low coolant level; Blockage in radiator shroud and ducting; Leaks in coolant hoses, engine block or water pump; Loose serpentine drive belt for the water pump; Engine overheating | Check the coolant level in the overflow jug; Restart the engine and read the coolant temperature, stopping the engine immediately if the coolant temperature is 230°F (110°C) or more; Allow the engine to cool, add coolant to the overflow jug if low and check the level of coolant in the radiator; Check the radiator shroud and ducting for blockage and remove any foreign matter; Inspect coolant hoses, engine block and water pump for visible leaks; Check the tension of the serpentine drive belt for the water pump; Remove the load on the generator and restart the engine, checking the coolant temperature and shutting the engine down immediately if it starts to overheat |
| Overcrank shutdown | Low fuel level in the tank; Improper operation of the fuel pump; Blocked air filter; Engine will not start | Check the fuel level in the tank; Check for proper operation of the fuel pump; Check the air filter for blockage; Consult the engine operator's manual for additional information on troubleshooting starting problems |
| Overspeed or underspeed shutdown | Engine speed out of adjustment (frequency above or below 60.0 Hz) | Disconnect all loads and restart the generator, read the frequency (Hz) on the LCD display (should read 60.0 Hz with no loads); If the frequency is above or below 60.0 Hz, adjust the engine speed per the engine operator's manual for throttle adjustments on mechanical governed units and the electronic governor manual for electronically controlled units |
