Galaxy Vector Controller GCM2, GCM3
3 - 18 Operation Issue 4 January 2008
If AC Failure alarms and Phase alarms are asserted while the
plant is in autoboost mode, the plant re-enters float mode,
retaining the remaining boost duration. If the Battery on
Discharge (BD) alarm asserts while the AC Failure or phase
alarm is active, the new multiplied time is be added to the boost
duration. When the AC Failure and Phase alarms retire, the plant
re-enters the boost mode for the remaining boost duration.
During autoboost, if the plant has a High Voltage, High Float
Voltage, or RFA alarm, the plant returns to float mode and the
remaining autoboost time is cancelled.

Battery/Generator
Test (PBT)
Plant Battery Test is a simple battery test feature available with
the Vector controller. When the controller receives a PBT signal
(either via an external input signal or, for use with the BLJ3
Terminal board only, via setting S1-7 to position 1), all the
rectifier output voltages are reset to 22V/44V so that the
batteries are placed on discharge. The plant voltage will drop to
only 22V/44V minimum, but remain at this voltage until the
PBT signal is released.
Vector does not reset the output voltage to 22V/44V, even if the
PBT signal is asserted, if there are any active major alarms or if
the serial communication alarm is active. If any major alarm
occurs during the test, the plant recovers to float mode and sets
all rectifiers back to the previous float setting.
Remote Access
and Monitoring
The Vector controller offers local and remote (modem or
Gateway) access capability to communicate and configure a
limited set of features using personal computers. It is possible to
communicate with the Vector controller by two means:
• By using any ANSI (American National Standards Institute)
character-based terminal including terminal emulators into
either local or modem ports or by using a PC Telnet
communication session via a TCP/IP LAN connection and a
Gateway card. The T1.317 command language is the human
to machine interface used for this communication. Refer to
Appendix-A for modem and Gateway details.
• By using Galaxy EasyView, which combines both a
communications package and a user friendly Microsoft
Windows interface (local or modem ports only).
