Alarm Description Explanation
Redundancy Loss The programmed number of redundant rectifiers in the
system is not sufficient. System load has exceeded the
redundancy limit.
Emergency Power Off Emergency Power off input closure to ground.
Reserve Time Low The predicted battery reserve time has fallen below the
programmed threshold.
Shunt Not Configured The shunt has been configured for either battery or load
type and the value programmed for shunt Amps is invalid.
Self Test Failed During initial boot, one or more of the tests performed on
the controller failed. This is a latched event, remaining
active until cleared by a user.
Thermal Probe Failure A temperature probe used for the Reserve Time Prediction
or Slope Thermal Compensation features is returning a
temperature outside of an acceptable range.
User Relay Conflict Battery management contactor LVD CN1, CN2, or CN3
has been configured for a type other than NONE and
associated user relay UR1, UR2, or UR3 has also been
assigned to report an alarm condition. This attribute is only
applicable in plants not using BIC cards.
Very Low Voltage The plant voltage is below the threshold set for VLV. This
is a critical alarm, indicating that load failures are
imminent.
ID Not Configured A device on the rectifier/converter serial bus has been
recognized without an assigned ID.
Clear Events
Events that have generated an Alarm and retired, but the Alarm remains active, may be
cleared using this feature. Alarms that remain, even though the condition has gone away,
are referred to as Latched Events.
