Russelectric Inc.
Russelectric on-site power control systems are equipped with dual PLC controls for automatic generator set starting and stopping, status and alarm annunciation, synchronizing, and priority load control. A primary PLC controls system operation with a backup PLC running the same program as the primary. If the primary PLC fails, the backup PLC assumes operational control. If both PLCs fail, a manual control system allows operating personnel to synchronize and parallel the generators onto the bus, as well as to add and shed load.
