Battery Charger Troubleshooting
If the red ERROR LED illuminates on the ICM display, see “05 Error
Causes Menu” on page 8–25 to determine the cause of the error condition.
Then use the solutions below to resolve the situation.
Problem Possible Cause Solution
AC1 LED is flashing, but
will not start charging
(allow 40 seconds to
synchronize). Battery voltage is below
the 22B Low Xfer (BX)
VDC setting.
You are outside of the
21 Grid Usage timer
period.
Check for the correct AC voltage or frequency at the
AC input terminal. If it is normal:
1) Check to see if the BX Mode is enabled. The AC
input is not allowed to synchronize and pass-through
unless the battery voltage reaches the 22B Low Xfer
(BX) VDC setting.
2) Check to see if the 21 Grid Usage timer (21B and
21C) is enabled and that you are outside of the
21 Grid Usage timer period. The AC is not allowed
to synchronize and charge unless you are within the
21 Grid Usage timer period.
AC1 or AC2 LED is
flashing, but will not start
charging
(allow 40 seconds to
synchronize). AC frequency at the AC
input terminal may be
out-of-tolerance (too high
or low) or the AC voltage
may be outside the
13C Input Upper Limit
VAC or 13D Input
Lower Limit VAC
settings. Check for the correct AC voltage or frequency at the
AC input terminal. If the AC source is a generator,
adjust the AC voltage or frequency accordingly.
AC1 or AC2 LED is
flashing and repeatedly
connects and disconnects
to the source. AC frequency at the AC
input terminal may be
out-of-tolerance (too high
or low) or the AC voltage
may be outside the
13C Input Upper
Limit VAC or 13D Input
Lower Limit VAC
settings.
Or the inverter circuit
breaker has opened.
Check for the correct AC voltage or frequency at the
AC input terminal. If the AC source is a generator,
adjust the AC voltage or frequency accordingly.
If the circuit breaker is open, press it back in to reset
it.
If circuit breaker on the inverter is not open, the
inverter may need to be serviced.
