Possible Causes/Solution
An incorrect voltage and frequency has been detected during
starting. Probable causes are:
1) Alternator damage. Contact Independent Authorized
Servicing Dealer.
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.
3) The engine may not be reaching its prescribed speed.
Proceed as follows:
•
Verify stepper motor is moving and linkage is free.
•
Verify stepper motor is plugged in.
•
Verify gas pressure is within specified limits.
The generator output voltage is too low. Probable causes are:
1) The load is too large. Remove load and attempt to restart
unit.
2) Alternator or AVR damage. Contact Independent Authorized
Servicing Dealer.
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 Independent Authorized
Servicing Dealer.
Unit detects no output voltage while starting.
1) Alternator damage. Contact Independent Authorized
Servicing Dealer.
Unit detects loss of output voltage while running.
1) Alternator damage. Contact Independent Authorized
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 is
running). KEEP FINGERS AWAY FROM FAN HOUSING-
PERSONAL INJURY CAN OCCUR IF FAN IS RUNNING.
Contact Independent Authorized Servicing Dealer.
4) Air leak in AVR enclosure. Contact Independent Authorized
Servicing Dealer.
5) Engine running too hot. Inspect air intake and exhaust.
6) Ambient temperature has risen above 60º F (15.5 °C).
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.
