Troubleshooting / Diagnostics
Possible Causes/Solution
Probable causes are:
1) The generator has been overloaded. Remove load and
attempt to restart unit.
2) Generator has started into a severe load. Manually
operate generator breaker and try to restart unit. If
problem persists, remove load and attempt to restart unit
again.
The DPE winding supplies this voltage.
1) Alternator damage. Contact servicing dealer.
Unit detects no output voltage while starting.
1) Alternator damage. Contact servicing dealer.
Unit detects loss of output voltage while running.
1) Alternator damage. Contact servicing dealer.
This alarm occurs when the AVR electronics temperature
exceeds 70 C. Possible causes are:
1) AVR filter faulty. Replace AVR filter.
2) Intake or exhaust air path is blocked. Check intake and
exhaust.
3) The BIG fan is not running (Note: only runs when the
engine is running). KEEP FINGERS AWAY FROM FAN
HOUSING- PERSONAL INJURY CAN OCCUR IF FAN IS
RUNNING. Contact servicing dealer.
4) Air leak in AVR enclosure. Contact servicing dealer.
5) Engine running too hot. Inspect air intake and exhaust.
6) Ambient temperature has risen above 60º F. Derate the
generator output per specifications.
If message is displayed when generator is stopped, also
check SMALL fan. Small fan RUNS for 60 minutes after
generator is stopped and keeps electronics cool during
heat soak.
Probable causes are:
1) Overload. Remove load and attempt to restart unit.
2) RPM sensor has failed. Contact servicing dealer.
3) Stepper motor problem. Contact servicing dealer.
1) Fuel problem (pressure loss). Check fuel supply and
attempt to restart unit.
2) Large overload. Remove load and attempt to restart
unit.
3) Throttle or engine problem. Contact servicing dealer.
Small fan current incorrect. Probable causes are:
1) Fan wiring or mechanical problem. Contact servicing
dealer.
2) Air path is blocked. Check AVR filter.
KEEP FINGERS AWAY FROM FAN HOUSING-
PERSONAL INJURY CAN OCCUR IF FAN IS RUNNING.
