5 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
5.1 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.
5.2 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.
• Fault Code Nos. 1, 2, 3, and 4 are first level faults. Pay close attention to the pause
sequence to avoid interpreting first level faults as second-level Fault Codes Nos. 11, 22, 33
or 44.
• To avoid the possibility of anyone misinterpreting Code Nos. 3 and 4 as Code Nos. 33 and
44, the latter have not been assigned faults.
5.3 Restoring Fault Code Blinking
The fault code stops blinking after five minutes. Press Stop three times within three seconds to
restore fault code blinking.
NOTICE
The last fault logged will blink even though the condition that caused the shutdown may have
been corrected.
