battery shunt to monitor the currents of all the plant batteries. The load
current displayed on the front panel is derived from the battery current
and the total rectifier output current.
A shunt type of NONE is selected for distributed architectures where no
shunt is directly connected to the shunt terminations of TB1 on the BJF
card of the Galaxy. Battery current may be measured via one or more
shunts read either by shunt channels of BIC cards (GPS systems) or by
remote peripheral monitoring modules. The load current displayed on
the front panel is derived from the battery current and the total rectifier
output current. Total rectifier output current is displayed if there are no
battery shunts present.
Use the <+> or <-> keys to change the field values. Press <Enter> to
save the changes.
BTP: This field is the Battery Thermal Protection Enable/Disable
switch. This field must be enabled for the Battery Thermal Protection
option to work. Use the <+> or <-> key to change the field value. Press
<ENTER> to save the change.
Note: BTP refers to the “STEP” battery thermal protection afforded by
the 210A or 210B BTP units that may be used with the Galaxy controller
and either serial or ferroresonant rectifiers that accept a “boost” control
signal. BTP need NOT be enabled to perform “SLOPE” thermal
compensation afforded by 210E STC units or other temperature
measuring means available with GPS BIC cards, when used in plants
with all serial rectifiers.
UNMAP BIC: When the Galaxy SC is used in systems with GPS serial
rectifier cabinets, these cabinets contain another serial device called a
BIC (Bay Interface Card). Each BIC has its own ID, just like the
rectifiers on the serial bus, set by a DIP switch located on its termination
board. If a BIC is removed or its ID is changed, Galaxy must be
informed to cease attempting to communicate with it. Use the <+> or
<-> keys in this field to bring up the BIC ID to be omitted from
configuration and then press <ENTER>.
RST PLV: This field, RST PLV, allows you to reset the display to
factory calibration for plant voltage (using the ADJ PLV field). With the
cursor on this field, pressing <ENTER> key will zero out the calibration
for the plant voltage. The plant voltage value displayed now is the true
value as recognized by Galaxy SC.
RST PLI: This field, RST PL, allows you to reset the display to factory
calibration for plant current (using the ADJ PLI field). With the cursor
