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 transfer switch back to utility position and try to
restart unit. If problem persists, remove load and attempt
to restart unit again.
The DPE winding supplies this voltage.
1) Alternator or brush damage. Contact servicing dealer.
Unit detects no output voltage while starting.
1) Alternator or brush damage. Contact servicing dealer.
Unit detects loss of output voltage while running.
1) Alternator or brush 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 (only runs when the engine

ING- PERSONAL INJURY CAN OCCUR IF FAN IS RUN-
NING. 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) A large load is not wired through the Loadshed module.
Contact installing dealer to correct installation.
3) Large overload. Remove load and attempt to restart
unit.
4) 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- PER-
SONAL INJURY CAN OCCUR IF FAN IS RUNNING.
