Ecode/Active
Alarm LED Problem Things to
Check
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 an 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 an 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 an 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 an Independent Authorized Servicing
Dealer.
4) Air leak in AVR enclosure. Contact an Independent
Authorized Servicing Dealer.
5) Engine running too hot. Inspect air intake and exhaust.
6) Ambient temperature has risen above 60 ºF (15.5 °C).
Derate the generator output per specifications.
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 an Independent Authorized
Servicing Dealer.
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.
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 an Independent
Authorized Servicing Dealer.
