9 Troubleshooting

By regularly performing the following periodic maintenance and guidelines, you greatly reduce

the chances of a genset shutdown.

• Maintain an appropriate oil level

• Keep battery connections clean and tight

• Do not overload the generator set

• Keep the air inlet and outlet openings clear

9.1 Troubleshooting With the In-Home Operator Panel

If a fault shutdown occurs the ACTION REQUIRED lamp on the in-home Operator Panel will

come on and the LCD screen will display the a description of the Fault, the Fault Number, and

the hour in total generator set running time when the Fault occurred.

The shutdown codes are listed below in numerical order along with step-by-step corrective

actions.

9.2 Troubleshooting with the Flashing Indicator Light

The status indicator light on the Control Switch inside the generator set flashes the diagnostic

fault code when a fault shutdown occurs. For a single-digit fault code (2 or 4), the light will flash

2 or 4 times and after a short pause will repeat.

For a two-digit fault code the light will flash the tens digit, pause and flash the units digit and

repeat after a longer pause. Fault 36 would be flashed as follows:

flash-flash-flash—pause —flash-flash-flash-flash-flash-flash—long pause —repeat

NOTICE

For fault history, go to the in-home Operator Panel.

9.3 Fault Code Blinking

At fault shutdown, the status indicator light will repeatedly blink sets of 1, 2, 3 or 4 blinks.

• One blink indicates shutdown due to high engine temperature.

• Two blinks indicate shutdown due to a loss of engine oil pressure.

• Three blinks indicate a service fault. Press Stop once to cause the two-digit, second-level

shutdown code to blink. (Pressing Stop again will stop the blinking.) The two-digit code

consists of 1, 2, 3, 4 or 5 blinks, a brief pause, and then 1 to 9 blinks. The first set of blinks

represents the tens digit and the second set of blinks the units digit of the shutdown code

number.

• Four blinks indicate that cranking time exceeded 35 seconds.
