Possible Causes/Solution
1048 VSCF
Overload RED Unit shuts down
during operation. Check the
LEDs/Screen
for alarms. Alternator, AVR or wiring is damaged.
Contact Independent Authorized Servicing Dealer.
1049 VSCF
Overload RED Unit shuts down
during operation. Check the
LEDs/Screen
for alarms. Generator output is shorted or severely overloaded. Identify
and clear the overload, and then restart.
1051 VSCF High
Battery YELLOW Yellow LED
illuminated in any
state.
Check the
LEDs/Screen
for alarms. Voltage supply to the AVR is high. If an external battery
charger is in use, contact installing dealer to correct
installation. If an external battery charger is NOT in use,
contact Independent Authorized Servicing Dealer.
1052 VSCF DC
Overvoltage RED Unit shuts down
during operation. Check the
LEDs/Screen
for alarms. Probable causes are:
1) The generator was temporarily overloaded.
2) The output was temporarily shorted. Try to restart the unit.
1053 VSCF Gate
Fault RED Unit shuts down
during operation
or starting. Check the
LEDs/Screen
for alarms. AVR is damaged. Contact Independent Authorized Servicing
Dealer.
1054 VSCF IGBT
Overtemp. RED Unit shuts down
during operation
or starting. Check the
LEDs/Screen
for alarms. Probable causes are:
1) Replace AVR filter. Inspect fan.
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.
