Configuration Error. Urgent Alarm, the charger cannot meet the target current
required by the controller even with all fitted charger modules operating or the
configuration does not meet the limits set for the selected AC supply.
Output Fuse. Urgent Alarm, a blown fuse in nearly all cases is caused by
connecting a reverse polarity battery to the charger. When a fuse is blown, check
all batteries for reverse cable connection. A common problem is with first charge
of shift batteries that have not been previously tested in a lift truck. After replacing
a battery or charger cable always closely check the polarity before plugging the
battery onto the charger.
No Output Current. Urgent Alarm, the charger is not providing the expected
output current. Generally related to a premature disconnection of the battery, but
also could be an incorrectly inserted charger module.
Monitor ADC Fail. Urgent Alarm, internal watchdog of the controller’s micro-
controller indicating a major fault and potentially unpredictable behaviour if the
charger is left running.
APC Communications Fail. Urgent Alarm, the APC module has failed to
communicate with the charger.
APC Incorrect Voltage. Urgent Alarm, the charger cannot produce the voltage
required by the APC.
APC Unknown Charger. Urgent Alarm, the charger cannot find the required
profile required by APC.
Charger Alarms

Mains Fail. Urgent Alarm, a mains loss situation and the charge cannot proceed.
Urgent Module Fail. Urgent Alarm, if the number of charger modules not providing
output equals or exceeds the setting for urgent module count in the monitor tab
then the charger will stop. If urgent module count is set to one then the charger is
configured without redundancy and a single fault will interrupt the charge cycle.
