Run the fault code test..
Fault Codes
The genset controller provides extensive diagnostics by causing the status indicator light on the Control Switch to blink in a coded fashion. Following a fault shutdown, the indicator light will repeatedly blink one, two, three or four blinks at a time.
• One blink indicates shutdown due to high engine coolant temperature.
• Two blinks indicates a low oil pressure fault.
• Three blinks indicates a service fault. Press Stop once to cause the
two-digit, second-level fault 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 rst set of blinks represents the tens digit and the second set of blinks the units digit of the fault code number. For example, Fault Code No. 36 appears as: blink-blink-blink—pause—blink-blink-blink-blink-blink-blink— long pause— repeat
• Four blinks indicates that cranking exceeded 30 seconds without the engine starting.
Note: Fault Code Nos. 3 and 4 are rst level faults. Avoid interpreting them as second-level Fault Code Nos. 33 and 44, which have not been assigned as fault codes.
