6.3. Battery Related Alarms

Over Discharged Battery

Battery is still under 1.9Vpc after 30
seconds of charge. Indicates a faulty
battery that needs investigation.
Default: Urgent

Deeply Discharged Battery

Battery initially is under 1.9Vpc but
recovers within 30 seconds of the
charge cycle start. This alarm normally
occurs when a battery is unplugged
from the lift truck and immediately
plugged into the charger. Default:Non-
Urgent

Sulphated Battery

Battery fails to complete a de-
sulphation profile applied by the
charger correctly and generally means
that the battery requires attention.
Default: Urgent

Incorrect Battery

Battery is inappropriate for the
configuration of the charger and cannot
be charged without reconfiguring the
charger to suit the battery. Default:
Urgent

Bulk Charge Timeout

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. May need additional charger
modules added to the charger. Default:
Urgent

Finishing Charge Timeout

Battery has exceeded the maximum
time allowed for the finishing part of
the charge cycle. Common with new
batteries with less than 10 charge
cycles. If the alarm occurs regularly,
investigation is advised and possible
adjustment of the charger or service of
the battery. Default:Non-Urgent

Battery Disconnected

Battery has been unplugged before
charge cycle has completed. This can
damage the battery connector and
increase risks of ignition of battery
charge gasses. If the battery needs to
be disconnected mid cycle, the charger
must be first set to STOP. A partial
charge cycle will be logged. Default:
Urgent

Reversed Battery

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 output
fuse(s). Batteries should always first
be checked for correct polarity BEFORE
plugging onto the lift truck or a
charger. Default: Urgent

Minimum dV/dt

Change in battery voltage over time.
Alarm occurs when the change in
voltage exceeds the value set in the
profile settings. This alarm also
indicates the termination of a
successful charge. Default:Non-Urgent

Maximum Cell Voltage

Occurs when the voltage per cell
exceeds the value set in the profile
settings. Typically 2.7V per cell for lead
acid batteries. Default:Non-Urgent

Batt Over Temp – Start

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. Default:
Urgent

Batt Over Temp - Charge

Occurs when the battery temperature
measured during a charge profile
exceeds the value set in the controller
settings. This alarm will allow the
charge profile to complete.
Default:Non-Urgent

+dI/dt

Occurs when the measured current in
the constant voltage stage is rising
instead of falling. This alarm will
terminate the charge profile. Default:
Urgent

Minimum Current

Occurs when using a IU profile and the
current in the constant voltage stage
falls below the value set in the profile
settings. This alarm will not stop a
profile and is considered normal for
some types of batteries. Default:Non-
Urgent

EQ/Refresh Timeout

Occurs when the time threshold in a
given stage of the equalize profile has
been exceeded. This alarm will
terminate the equalize charge but is
not considered an urgent alarm.
Default:Non-Urgent
