Voltage Dips, Interruptions, and
Variations
MSC is suitable for use in power plants with or without batteries. In battery less plants, the loss of ac
power causes an immediate loss of dc power to the controller and the activation of all office alarm
relays. When ac power is restored, plant rectifiers will return to their last specified voltage set point,
and the controller will automatically return to its last configuration.
Alarm and Control Signals
In a standard Galaxy Power System (GPS) configuration, plant level alarms are sent to the controller via
the Bay Interface Card through serial data communication. The following alarm inputs are provided for
discretionary use in other applications.
