Wiring Method:
X1 voltage input socket: X1/1-X1/3 400V/50HZ or X1/3-X1/5 230V/50HZ
X2 external socket: X2/1-X2/3 external voltage setting potentiometer (4.7K)
X2/5, X2/9 Tolerance Current Access Interface (0.4-0.6A)
X2/7, X2/10, X2/11 reactor power input interface
X2/12(+), X2/4(-) DC excitation output interface (no power expansion)
X3 Power Expansion Socket X40 Special Type Controller Socket
Use and Adjustment:
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.
