Byte 0 Excitation Mode – this byte indicates the state of the excitation mode:
0x00 – Exciter Off
0x01 – Exciter On
Byte 1 Frame Size – the Least Significant Byte of the frame size used for the controller
Byte 2 Frame Size – the Most Significant Byte of the frame size used for the controller
Byte 3 Input Source – the input source used for providing power to the regulator:
0x00 – Unused
0x01 – Permanent Magnet Generator
Byte 4 Current Sense Phases – the number of current phases sensed directly through cur-
rent transformers:
0x00 – Three-phase current sensing
0x01 – Single phase current sensing
Byte 5 VR Status – the current operating status of the regulator:
0x00 – Run (regulator operating normally)
0x01 – Off (regulator excitation is off)
0x02 – Alarm (regulator is in alarm state)
0x03 – Fault (regulator is in fault state)
Byte 6 Regulation Mode – the current regulation mode of the regulator:
0x00 – AVR3 (Automatic Voltage Regulation using three phases)
0x01 – FCR (Field Current Regulation)
0x02 – AVR1 (Automatic Voltage Regulation using single phase)
Byte 7 Device Mode – the current device mode for the regulator
0x00 – diagnostics and testing
0x01 – DEVICE_ON (excitation is enabled and regulator is operating normally)
0x02 – diagnostics and testing
0x03 – diagnostics and testing
0x04 – diagnostics and testing
0x05 – diagnostics and testing
0x06 – diagnostics and testing
