Primary voltage setting with resistors connected: 230V
Hint:
Disconnect one wire (OUT 1), set voltage on running Generator to U
= nom.
Measure Voltage over Resistor
Depending on Value increase AVRi potentiometer to get Range.
Set exact Value with Bias Voltage//PF regulation (gain=0)
Stop gen-set and connect when equal Voltage and polarity is
achieved.
Set again in regulation loop on demand
