Onan Genset Genset Maintenance
22
Governor overload fault
The duration of operation at or near full-duty
cycle was beyond the design limit.
1. Disconnect any extra loads.
2. Check for and repair fuel leaks. Air in the fuel
supply can disrupt frequency. Prime the
engine fuel system by holding the control
switch at Stop for one minute.
3. Replace the engine air filter.
4. Clean the spark arrestor.
5. Replace the fuel filter.
24
Temperature sender fault
The controller sensed that the sender circuit is
either open or shorted
See authorized Cummins Onan dealer.
27
AC voltage sensed fault
The controller was unable to sense output volt-
age.
See authorized Cummins Onan dealer.
29
High battery voltage fault
The controller sensed battery system voltage
greater than 19 volts.
See authorized Cummins Onan dealer.
32
Low cranking speed fault
Cranking speed less than 100 rpm (2.5 Hz) for
more than 12 seconds.
1. Clean and tighten the battery connections.
2. Recharge or replace the battery.
3. Replace the engine oil with oil of the proper
viscosity for the ambient temperature.
35
Control card fault
Microprocessor EEPROM error during self test
See authorized Cummins Onan dealer.
36
Engine stopped fault
The genset stopped without a command from
the controller.
1. Check fuel level; refill fuel tank.
2. Check for and repair fuel leaks. Air in the fuel
supply can disrupt frequency. Prime the
engine fuel system by holding the control
switch at Stop for one minute.
3. Replace engine air filter.
4. Replace the fuel filter.
38
Field overload fault
Field voltage exceeded 150VDC
See authorized Cummins Onan dealer.
41
Shorted rotor fault
The rotor circuit is shorted to ground.
See authorized Cummins Onan dealer.
42
Processor fault
Microprocessor ROM error during self test
See authorized Cummins Onan dealer.
43
Processor fault
Microprocessor RAM error during self test
See authorized Cummins Onan dealer.
45
Speed sense fault
Controller unable to sense quadrature fre-
quency
1. Check fuel level; refill fuel tank.
2. Check for and repair fuel leaks. Air in the fuel
supply can disrupt frequency. Prime the
engine fuel system by holding the control
switch at Stop for one minute.
