Battery Disconnected. Urgent Alarm, the battery has been unplugged before
charge cycle has completed. This can damage the battery connector and increase
risks of battery explosions as sparks around batteries at their top of charge whilst
gassing can be very dangerous. If the battery needs to be disconnected mid
cycle, the toggle switch must be first set to STOP. This will stop the charge and
log a partial cycle in the charge log but allows safe disconnection of the battery.
Reversed Battery. Urgent Alarm, a battery with positive and negative cables
reversed has been connected to the charger. Generally this will also cause an
output fuse alarm and the need to replace the charger’s DC output fuse(s). Such
a situation is not covered by warranty as new batteries should always first be
checked for correct polarity BEFORE plugging onto the lift truck or a charger.
Batt Over Temp - Start. Urgent Alarm, occurs when the battery temperature
measured before a charge profile starts exceeds the value set in the controller
settings. This alarm will not allow the charge profile to continue.
+dI/dt. Urgent Alarm, occurs when the measured current in the constant voltage
stage is rising instead of falling. This alarm will terminate the charge profile.
Battery Alarms
- continued
Bulk Charge Timeout. Urgent Alarm, the battery has exceeded the maximum
time allowed for the initial constant current bulk charge phase. Could indicate a
faulty battery or the charger configuration is not correct for the size of battery to
be charged. May need additional charger modules added to the charger.
Over Discharged Battery. Urgent Alarm, the battery is still under 1.9V per cell after
30 seconds of charge which indicates a faulty battery that needs investigation.
Sulphated Battery. Urgent Alarm, deactivated by default.
Incorrect Battery. Urgent Alarm, the battery voltage is inappropriate for the
configuration of the charger and cannot be charged without reconfiguring the
charger to suit the battery. Note: An incorrectly configured APC can cause this
alarm.
