Controller Alarm Descriptions
Controller Alarm Descriptions
Alarm Description Explanation
ACO Active Alarm Cut-Off has been initiated to silence local audible alarms. Any
subsequent Power Critical, Power Major, or Power Minor alarm disables
ACO. A programmable ACO time-out period for each alarm severity
resets silenced alarms.
Alarm Battery Supply Operated ABS fuse (F2) on Millennium II’s MCR1 card.
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 its output distribution.
Converter ID Conflict The ID for a converter connected to the controller’s serial bus is the same
