Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 18
Controller
Failure
The Galaxy SC has three distinct levels that allow isolated failures to
reduce but not eliminate control and monitoring of the battery plant. The
three levels are the independent controller, the intelligent controller and
the analog backup selective high voltage circuitry.
If the independent controller fails or is removed, then the following
responses occur:
• All rectifier control and monitoring is lost except for the backup
selective high voltage function;
• The plant mode will revert to float mode;
• The energy management algorithm is inoperative;
• Plant voltage and current monitoring is lost;
• Office alarm monitoring is lost;
• All the alarm relays operate;
• The front panel no longer works;
• The front panel LEDs no longer work;
• Alarm Cut-Off (ACO) no longer works;
• The intelligent controller continues to operate normally and can be
accessed via the local, modem, and auxiliary ports;
• The Independent Controller Circuit Pack Failure alarm (Power
Major) is created.
If the intelligent controller fails or is removed, then following responses
occur:
• All LEDs and alarm relays activated at the time of failure or
removal will remain activated until the alarm relay activation
condition is removed and either the independent controller is reset
or the intelligent controller becomes operational again;
• The plant mode will revert to float mode;
• The independent controller will assume control of the front panel
display (simplified feature set);
• The energy management algorithm is inoperative;
• Alarm test is aborted;
• signals are retired; and
• The Intelligent Controller Circuit Pack Failure alarm (Power
Major) is created.
Data Switch The data switch feature gives remote access via a Galaxy SC access port
to equipment connected to the Galaxy SC at any of four data switch
RS-232 ports. This feature can operate in a pass-through mode or in an
alarm reporting mode.
