Automatic Voltage Regulator – AVR-A-OPT-04E / AVR-A-OPT-05PE l 13
6 BLOCK DIAGRAM
Figure 6.1: Block diagram
7 TRIMPOTS FUNCTION
P1: Voltage adjustment
P2: Droop adjustment.
P3: Stability - 2 adjustment.
P4: Stability - 1 adjustment.
P5: Under frequency adjustment.
8 TRIMPOTS ADJUSTMENT
P1: Rotating CW, voltage increases.
P2: Rotating CW, reactive compensation range increases.
P3: Rotating CW, dynamic response will be slower.
P4: Rotating CW, dynamic response will be slower.
P5: Rotating CW, U/F range increases and rotating CCW, it decreases.
NOTE
* A potentiometer may be connected for fine voltage adjustment (5 k
Ω
/ 3 W) at terminals 6 and 7.
* The P3, P4 and P5 trimpots were preseted and sealed, but if adjustments are required, They can be
performed according to the procedures described in this manual.
