1055 VSCF Phase
Error
RED
Unit shuts down
during starting.
Check the
LEDs/Screen
for alarms.
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.
1056 VSCF
Undervoltage
RED
Unit shuts down
during operation
or starting.
Check the
LEDs/Screen
for alarms.
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.
1057 VSCF
Overvoltage
RED
Unit shuts down
during operation
or starting.
Check the
LEDs/Screen
for alarms.
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.
1058 VSCF DC
Undervoltage
RED
Unit shuts down
during operation
or starting.
Check the
LEDs/Screen
for alarms.
The DPE winding supplies this voltage.
1) Alternator damage. Contact Independent Authorized
Servicing Dealer.
1059 VSCF
Field Loss
RED
Unit shuts down
during starting.
Check the
LEDs/Screen
for alarms.
Unit detects no output voltage while starting.
1) Alternator damage. Contact Independent Authorized
Servicing Dealer.
1061 VSCF
Field Loss
RED
Unit shuts down
during operation.
Check the
LEDs/Screen
for alarms.
Unit detects loss of output voltage while running.
1) Alternator damage. Contact Independent Authorized
Servicing Dealer.
1060 Big Fan
Failure
RED
Unit shuts down
during operation.
Check the
LEDs/Screen
for alarms.
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 140º F (60° 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.
