disconnecting the battery
from the charger
High Amp-Hours
Occurs when more than 150% of battery
Amp-Hours are returned during the charge
cycle
Call Service – NO
Bar Graph – Steady On
Can be reset by
disconnecting battery from
the charger
AC Voltage Fault
Occurs when input AC voltage quality is
poor or distorted. Note that this condition
may be temporary. The charger will attempt
to re-start after 3 minutes. If unsuccessful,
will attempt a total of 4 times before a
permanent fault condition occurs.
Call Service – NO, ON
when fault is
permanent.

ON, Flashes when fault
is permanent
Can be reset by
Disconnecting and
reconnecting battery to the
charger. Disconnect AC
power & check AC source.
AC fuse blown
Or lost phase
Occurs when AC fuse is blown or a phase of
AC power is interrupted when the charger is
charging a battery. Note that this condition
may be temporary. The charger will attempt
to re-start after 3 minutes. If unsuccessful,
will attempt a total of 4 times before a
permanent fault condition occurs.
Call Service – NO
Bar Graph – Steady
