Electronic built- in )overload, short circuit, and loss of sensing) protecting: If excitation current raises over 10 amps for more then 10 seconds, excitation current will drop automatically to about 1A.
To reset AVR protection, the generator must be stopped )or by cutting supply voltage to the AVR). Protection of power inputs by fuses F1
Voltage sensing: 5VA insulated transformer with input voltage taps at: Terminals 0 - 110V = 95 to 140V. Terminals 0 - 220V = 170 to 260V. Terminals 0 - 380V = 340 to 520V
