BSL - 63 FAJ: Fuse Alarm Major
An optional battery potential input, must use an external 1K ohm 2W current limiting resistor at the
source. A Fuse Alarm Major is generated when battery potential is received.
BSL - 65 FAN: Fuse Alarm Minor
A battery potential input is required, which must use an external 1K ohm, 2W current limiting resistor at
the source. A Fuse Alarm Minor is generated when battery potential is received.
BSL - 72 OS: Open String Alarm
A battery potential input is required, which must use an external 1K ohm 2W current limiting resistor at
the source. This circuit is used to signal Galaxy that a battery string protective device or switch is in the
open position. An Open String Alarm is generated when battery potential is received.
BSL - 64 AMJ: Aux Major
A battery potential input is required, which must use an external 1K ohm, 2W current limiting resistor at
the source. This circuit is used to allow Galaxy to monitor another power device and provide alarms for
it. An Aux Major Alarm is generated when battery potential is received.
BSL - 66 AMN: Aux Minor
A battery potential input is required, which must use an external 1K ohm, 2W current limiting resistor at
the source. This circuit is used to allow Galaxy to monitor another power device and provide alarms for
it. An Aux Minor Alarm is generated when battery potential is received.
LVD1: BSL - 84 Low Voltage Disconnect Active
A battery potential input is required, which must use an external 1K ohm, 2W current limiting resistor at
the source if not using standard ABB Power LVD circuit boards or controller. This circuit is used to
inform Galaxy that the monitoring circuit of a Low Voltage Disconnect device has failed. In standard
Galaxy Power Systems, the Bay Interface board monitors these alarms and informs the Controller
through the serial interface connection.
LVD2/LVD2R: BSL - 61/62 Low Voltage Disconnect Active
A closure between these points or a ground signal into LVD2/ BSL - 61 is used to inform Galaxy that the
a Low Voltage Disconnect device has opened. In standard Galaxy Power Systems, the Bay Interface
board monitors these alarms and informs the Controller through the serial interface connection.
External Boost Option
A variety of external devices may be used to initiate boost in Galaxy. Wiring is required from positions
67/68/69 on the BSL board for operation of this feature. Providing a contact closure between TBST and
TRTN initiates the boost feature. A contact closure between TFLT and TRTN returns the plant to float.
Additional information on External Boost can be found in the User ’ s Guide for Millennium II Controller
Advanced Features manual.
Rectifier Sequence Option
