Fuse Alarm Major (FAJ) - BSL-63
A battery potential input is required, which must use an external 1K ohm 2W current limiting resistor at the source. A Fuse
Alarm Major is generated when battery potential is received.
Fuse Alarm Minor (FAN) - BSL-65
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.
Open String Alarm (OS) - BSL-72
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 the controller that a battery string protective device or switch is in the open position. An Open
String Alarm is generated when battery potential is received.
Aux Major (AMJ) - BSL-64
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 the controller to monitor another power device and provide alarms for it. An Aux Major Alarm is
generated when battery potential is received.
Aux Minor (AMN) - BSL-66
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 the controller to monitor another power device and provide alarms for it. An Aux Minor Alarm is
generated when battery potential is received.
Low Voltage Disconnect Active (LVD1) - BSL-84
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 cards or controller. This circuit is used to inform the controller that the
monitoring circuit of a Low Voltage Disconnect device has failed. In standard Galaxy Power Systems, the Bay Interface Card
(BIC) monitors these alarms and informs the Controller through the serial interface connection.
Low Voltage Disconnect Active (LVD2/LVD2R) - BSL-61/62
A closure between these points or a ground signal into LVD2/ BSL-61 is used to inform the controller that a Low Voltage
Disconnect device has opened. In standard Galaxy Power Systems, the Bay Interface Card (BIC) monitors these alarms and
informs the Controller through the serial interface connection.
External Boost Option (TFLT/TBST/PBT) - BSL-67-69
A variety of external devices may be used to initiate boost in the controller. Wiring is required from positions 67/68/69 on
the BSL card 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 Hold OFF on Engine Option (RO/ROR) - BSL-77-78
The controller accepts a contact closure between RO/ROR (BSL-77-78) to hold OFF rectifiers configured as “Remote Group
Standby”
These controller inputs hold OFF individual rectifiers or groups of rectifiers under external control.
Internal Sequencing
- The controller can hold OFF individual rectifiers when AC is being provided by emergency generator.
Internal Rectifier Sequencing requires external wiring to RO/ROR on BSL pin numbers 77/78, to function.
