2 - R 726 : REGULATION OF POWER FACTOR (2F) AND MAINS VOLTAGE SENSING (3F)
The power factor and mains voltage sensing are regulated by the R726 module. See the specific manual.

2.1 - potentiometers

P1: Potentiometer for adjusting the alternator voltage to the mains voltage (operating mode 3F).
P2: Adjustment of the power factor
P3: Stability
P4: Limitation of the power factor
