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 Lineage 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.
