the total rectifier output current.
Use the <+> or <-> key to change the field
values. Press <ENTER> to save the changes.
mV The first item to configure is the Plant
Voltage shunt. Make sure the cursor is on the
SHUNT mV field and use the <+> or <-> key to
step through the available values (25, 50, 60,
100, 150 mV). Select the one that best suits
the application; press the <ENTER> key to
save the change.
I Move the cursor to the SHUNT I field by using
the <UP>/<DOWN>/<LEFT>/<RIGHT> ARROW
keys. Use the <+> or <-> key to step through
the available values (0-99999). Select the
desired value; press <ENTER> to save the
change.
4. ALARM
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
