Interpreting alarms
The Battery Management System can generate Major or Minor alarms.
•A Major alarm requires immediate action to ensure that the batteries
are able to provide back-up power.
•A Minor alarm indicates a condition that is not likely to result in the
batteries being unable to provide back-up power, but could develop
into a major alarm, or could prevent the detection of a major alarm.
Each alarm type will close an associated normally-open alarm relay. The
alarm relays can be connected to a device that monitors normally-open and
normally-closed sensors.
Sensor calibration. The Battery Management System is in sensor
calibration mode. You can set this mode by setting DIP switch 4 (on each
sensor) to On. The Battery Management System will then obtain a new
zero value. The LEDs will flash at a rate of once per second while the
Battery Management System is in this mode. After five flashes, the sensor
is calibrated.

Do not perform sensor calibration while there is current flowing
through the sensor. Remove the sensor from the battery cable
before performing a sensor calibration.
