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
relay, light 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.
5. Rectifiers
Setpoint This value sets the system voltage for all
serial rectifiers. Move the cursor to the field
and use the <+> or <-> key to adjust the
threshold value. Press <ENTER> to save the
change.
HVSD The configuration of this field sets the
internal high voltage shutdown value of all
serial rectifiers. Move the cursor to the field
