Temperature Configuration.

Alarm Configuration.

Maximum Pilot
Temperature Limit

The maximum surface temperature of the pilot battery in
the string (the battery to which the pilot temperature sensor
is attached). Because the Battery Management System
equalizes the charge for all batteries in the string, the
temperature of the pilot battery is likely to be typical of
other batteries in the string. For example, an overheated
pilot battery would probably indicate overcharging
throughout the string.

Maximum Ambient
Temperature Limit

The maximum and minimum allowable temperature of the
air surrounding the batteries. See the specifications for
your batteries before changing this value.

Minimum Ambient
Temperature Limit

Ripple Current Limit

Ripple current limit is the allowable AC
measurement in the battery string. The default
setting is 5 A for every 100 amp-hour of capacity.

Charge Current Limit

Percentage of change in the response current
measurement that is allowed before an alarm is
indicated.

Discharge Voltage Limit

The percentage of the lowest individual battery
discharge voltage that is allowed relative to the
other batteries in the string.

Automatic Annuciator Reset

When enabled, the external annunciator devices
will reset automatically when the condition of an
alarm clears. When disabled, the alarm must be
reset manually.
