1. Switch "/1". "/2". "/3" is initially set to the "ON" position. When the external potentiometer is used, "/3" is turned to the "OFF" position. Note: It is forbidden to open "/1". "/2" when loading!
2. "S" adjustment potentiometer: The right-hand adjustment is increased, and it is set to 0 when the unit is running. The adjustment method of parallel operation: when the power factor is 1, the generator voltage does not decrease; when the power factor is 0, the generator voltage is reduced by 6%; when the power factor is 0.8, the generator voltage is correspondingly reduced by 3.6%. .
3. "U" internal voltage setting potentiometer: the swing voltage is set high, the reverse voltage is set low, and the initial value is about 20%.
4. "K" gain control potentiometer: adjust the stability, rotate counterclockwise to 25% position, the control system tends to be stable, the initial value is 50% position; the right-handed gain is increased, too large may cause voltage instability.
5. "T" dynamic time control potentiometer: adjust the reaction time, that is, the dynamic stability energy, the clockwise rotation reaction is slow, and the counterclockwise rotation reaction is fast. The initial value is 50%. Reacting too fast may cause large voltage fluctuations
6. "R47" disturbance potentiometer: adjust the feedback deviation signal to improve the dynamic performance, the initial value is 0% position
7. BR1 short wiring, disconnection can reduce the gain by 25%, K potentiometer rotates to 0, and the voltage is still unstable.
