Wiring:
1. V0-V220, V0-V380 voltage measurement input.
2. E+, E-excitation output.
3. X1-X2 power input terminal, this power supply can be PMG, full harmonic, auxiliary winding, line power supply, etc.
4. S1-S2 current compensation input, using current transformer secondary side current is 1A.
5. VR1-VR2 remote voltage regulation, connected to 1KΩ/1W adjustable resistor. First adjust the adjustable resistor to about the midpoint and connect it to VR1 and VR2. Then adjust the AVR voltage to adjust the potentiometer to the voltage to be adjusted. The adjustable resistor can adjust the output voltage by ±20V.
6. A1-A2 accepts an external DC voltage source to control the generator output voltage, and is connected to a voltage source of ±1V. With TRIN potentiometer, the adjustment range is -20--+20V
Adjustment Settings:
1. OTLT: generator output voltage adjustment, CW adjustment of output voltage drop, CCW rise
2. STAB: The generator voltage stability is adjusted, and the stability is strengthened, and CCW is weakened.
3. UFRO: low frequency protection setting, CW frequency decreases, CCW frequency increases
4. DIP: V/Hz reduction ratio adjustment during low frequency protection, CW decrease, CCW increase.
5. DROOP: Current compensation component adjustment, CW reduction, CCW increase.
6. TRIM: Analog voltage input component adjustment, CW reduction, CCW increase. This potentiometer is on the front left corner of the AVR.
