Alarm Description Explanation
AC Fail A rectifier is reporting an ACF to the controller.
Auxiliary Major A resistive battery potential is present on the AMJ alarm
input BSL-64, indicating a major alarm is active in the
external equipment connected to this point.
Auxiliary Minor A resistive battery potential is present on the AMN alarm
input BSL-66, indicating a minor alarm is active in the
external equipment connected to this point.
Alarm Test Active Alarm Test is currently active. Any real alarm with a
severity of Critical, Major or Minor, other than RFA or
HV, aborts an active Alarm Test.
Alarm Test Aborted Alarm Test has been aborted by an alarm. This is a latched
event, remaining active until cleared by a user.
Memory Backup Battery
Low The controller memory battery requires replacement.
Battery Type Conflict The DC Plant – Battery Type and Battery Management –
Battery Test Class attributes (sealed vs. flooded) do not
match.
Battery On Discharge The plant voltage is below the threshold set for BD in the
present plant mode, FLOAT or BOOST/BTP. This alarm
will not retire immediately upon rectifier restoration after
an extended discharge. Plant voltage will not fully recover
until depleted battery energy has been replaced. Do NOT
adjust the rectifier voltage adjustments if they are at or near
rated output currents.
Battery Test Failed A Battery Test was aborted before a reserve time could be
established. This is a latched event, remaining active until
cleared by a user.
Bay Interface ID Conflict The ID for a BIC (Bay Interface Card) connected to the
controller’s serial bus is the same as that of a previously
installed BIC.
Battery Test Active A Battery Test session has been initiated. (Available only
in plants with all serial rectifiers. Rectifier voltage has been
lowered and the batteries are discharging.) The BD LED
and BD relays are active and both the BD and VLV alarm
thresholds along with STC (Slope Thermal Compensation)
are inhibited while the Battery Test is active.
Configuration Changed A change has been made to a configuration setting. This is
a latched event, remaining active until cleared by a user.
Converter Distribution
Fuse A converter distribution module connected to the
controller’s serial bus is reporting an operated fuse in it’s
output distribution.
Converter ID Conflict The ID for a converter connected to the controller’s serial
bus is the same as that of a previously installed converter.
