is on this field, pressing the <ENTER> key will zero out the delta for the
plant current. The plant current value displayed now is the true value as
computed by Galaxy SC from the shunt reading.
Alarm Thresholds
Menu
From the CONFIGURATION menu select THRESH to bring up the
THRESH menu. This menu screen allows you to configure the alarm
threshold for the High Voltage alarm (HV), High Float Voltage alarm
(HFV), Battery Discharge alarm (BD), Very Low Voltage alarm (VLV)
and the Rectifier On Threshold for both FLOAT and BOOST mode.
There is one read-only field in this menu, the High Voltage Backup (the
value of which is determined by a set of hardware switches). See
Appendix F for additional information on configuration parameters for
these fields. The THRESH menu should look like this:
High Voltage (HV) threshold: There are two values for this alarm, one
for the FLOAT mode, the other for the BOOST/BTP mode. When the
plant voltage exceeds this threshold, the plant High Voltage Alarm
(HVA) is turned ON, and the rectifier interface will send a signal to the
rectifiers for shutting down according to an orderly and timely fashion.
This will also light the Major (MJ) Led, 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 both FLOAT and BOOST mode to
the desired level. Press <ENTER> to save the change.
High Voltage backup threshold: This is a read-only field, the value
display on this field is determined by DIP switches SW200 and SW201
on the BJB board setting. This value normally is larger than the HV/
FLOAT or HV/BOOST threshold. This setting has no effect in a plant
that uses serial rectifiers.
High Float Voltage alarm threshold: There are two values for this
alarm, one for the FLOAT mode, the other for the BOOST/BTP mode.
When the plant voltage exceeds this threshold, the plant High Float
Voltage Alarm (HFV) is turned ON. This will also light the Minor LED
