THRESHOLDS
High Voltage When the plant voltage exceeds this threshold, the plant High
Voltage Alarm (HVA) is turned ON, and the controller will
send a signal to the rectifiers to shut down in an orderly and
timely fashion. This will also light the Major (MJ) LED, and
activate the PMJ relay (assuming there is no alarm with
CRITICAL severity level active). Move the cursor to the fields
and use the <+> or <-> key to adjust the High Voltage shut
down alarm for FLOAT mode to the desired level. Press
<ENTER> to save the change.
High Voltage Float When the plant voltage exceeds this threshold, the plant High
Float Voltage Alarm (HFV) is turned ON, and this will also
light the Minor LED, activate the PMN contact closure
(assuming there is no alarm with CRITICAL or MAJOR
severity level active). The purpose of this alarm is to indicate
that the plant voltage is high probably due to an adjustment in
the plant rather than due to a failure. This alarm allows the
High Voltage (HV) shutdown threshold to be raised slightly,
thus reducing the number of nuisance shutdowns without
decreasing the plant reliability. Move the cursor to the fields
and use the <+> or <-> key to adjust the High Voltage shut
down alarm for FLOAT mode to the desired level (normally
less than the HV threshold). Press <ENTER> to save the
change.
Battery on Discharge If the plant voltage is less than the threshold value, the Battery
Discharge alarm is turned ON, this in turn activates the PMJ
and BD relays, and lights the MAJ and BD LEDs. Move the
cursor to the fields, and use the <+> or <-> key to adjust the
threshold to the desired level. Press <ENTER> to save the
change.

Very Low Voltage This alarm threshold is used to indicate that the system voltage
is very low, and that the batteries have discharged to a
dangerously low depth. When the plant voltage falls below this
level, the Very Low Voltage (VLV) and Power Critical alarm
will be generated. Move the cursor to the field and use the <+>
or <-> key to adjust the threshold value. Press <ENTER> to
save the change.
