SG Microprocessor Controller

The SG Microprocessor controller controls and monitors unit operation, records system faults and performs an automatic pre-trip check. The controller monitors all unit protection shutdown functions and the exciter system. The controller shuts down unit operation due to low engine oil pressure, low engine oil level, high coolant temperature, or alternator overload. The module also delays excitation power supply for 2 minutes after unit start-up. The SG Microprocessor controller is designed with the capability to have the software flash loaded.
