correctly and generally means that the battery requires attention.
Incorrect Battery

Bulk Charge Timeout
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.
Finishing Charge Timeout
finishing part of the charge cycle. Generally not a problem and indicates the battery did not quite perform as
expected. Not uncommon with new batteries that are still cycling up to full capacity (allow 10 cycles) however if
the alarm is a regular occurrence it needs investigation and possible adjustment of the charger or service of the
battery.
Battery Disconnected
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
charger. Generally this will also cause an output fuse alarm and the need to replace the chargers 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.
