Deeply Discharged Battery. Non-Urgent Alarm, the battery at start is under
1.9V per cell but recovers within 30 secs of charge, normally comes up when the
battery is quickly unplugged from the lift truck and plugged into the charger.
Finishing Charge Timeout. Non-Urgent Alarm, the battery has exceeded the
maximum time allowed for the finishing part of the charge cycle. Generally not a
major 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.

Minimum dV/dt. Non-Urgent Alarm, details the change in battery voltage over
time. The alarm occurs when the change in voltage exceeds the value set in
profile settings. This alarm also indicates the termination of a successful charge.
Maximum Cell Voltage. Non-Urgent Alarm, occurs when the voltage per cell
exceeds the value set in the profile settings. Typically 2.7V per cell for lead acid
batteries.
Batt Over Temp - Charge. Non-Urgent Alarm, occurs when the battery
temperature measured during a charge profile exceeds the value set in the
controller settings. This alarm will not allow the charge profile to continue.
Minimum Current. Non-Urgent Alarm, 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.
EQ/Refresh Timeout. Non-Urgent Alarm, occurs when the time in a given stage
of the equalize profile has exceeded the value set for that stage of the profile. This
alarm will terminate the equalize charge but is not considered an Urgent Alarm.
