• SPECIFICATIONS： Normal AVR delivery power: 2 auxiliary windings (X1, X2, andZ, Z2) Shunt supply: 150V /60Hz Rated overload current: 15A, 10s Electronic biltlin (overload, quick circuit, and loss ofsensing) protection: If excitation latest raises over 10Amps for extra then 10 seconds, excitation recent will drops robotically to about 1A To reset AVR protection, generator should be stopped (or through cutting supply voltage to the AVR) Protection of power inputs by means of fuses F1 Vollage sensing: 5VA insulated transformer with input voltage taps at: Terminals 0-110V = ninety five to 140V Terminals 0-220 V= 170 to 260 V Terminals 0-380 V = 340 to 520V Output Vltage adjustment by utilizing pot P2 Other sensing vltages by utilizing an adapting different transformers Curent sensing (arall operation) CT 2 VA category 1 secondary latest oo/1 (optional) Adjustment of quadrature hunch with pot P1 Under-speed (U/F) and LAM protection: for knee frequency adjustable use P4 Excitation over crrent adjustment use P5: 4 to 15A For 50/60 Hz (U/F) solection use jumper ST3 Load acceptance module： LAM is suppressed by slicing twine marked ST5 LAM (Load Acceptance Module) operate When applying a step load to the generator, the rolational pace (frequency) of the genset drops I the speed is under the preset frequency the "L AM circuits drops the voltage about 15% and this way reducing the tremendous step t about 25%。as long as the speed has not recovered to normal values The "LAM" is used both to reduce the speed drop of the engine, during the step load, or to increase the relevant step load for a similar speed variation (turbo charged engines) so the engine can get well usual pace quickly To prevent ollage silltions, the frequency threshold should be adjusted about 2 Hz under the lowest frequency in usual operation
