No. 15 –Under Frequency
Frequency was less than 54Hz for more than 8 seconds.
No. 19 –Actuator Shorted or Open
Before cranking, the controller sensed an open or shorted
governor actuator or wiring.
No. 22 –Actuator Overload
Due to overloaded AC output or poor engine performance, the
controller kept the governor actuator at full-duty cycle for 60
consecutive seconds.
No. 24 –Faulty Engine Temperature Sender
After 10 minutes of running, the controller sensed an open
temperature sender or wiring.
No. 27 –VAC Sense Lost
While running, the controller lost stator AC sensing voltage even
though the field was functioning normally.
No. 29 –High Battery Voltage
Before cranking, the controller sensed that incoming battery
voltage was greater than 19.2 volts for 5 milliseconds, or greater
than 19.2 volts for 1 second, while running.
No. 32 –Starting Fault
The controller could not detect cranking speed for 12 seconds.
Possible open quadrature winding or broken brushes/dirty
sliprings.
No. 35 –EE Checksum Fault
During startup, the controller detected an EE memory error.
No. 36 –Mechanical Fault
While running, engine speed fell to less than 1000RPM for .5
seconds, un-commanded by controller. This code can come up
when genset runs out of fuel.
No. 38 –Field Overload
While running, field voltage was higher than 180VAC for 10
seconds.
