Description
Nominal current of the primary side of the current transformer connected to the
controller terminals labeled IN. The secondary side is adjusted by setpoint
Im3/ErFlCurCTs.

Description
The setpoint is used to adjust the generator voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.0 if the generator voltage is connected directly
to the controller terminals, i.e. without transformers.
NOTE:
Example: if you have transformers with ratio 6000/100V adjust the setpoint to the
value of 60.0.
NOTE:
The range of the generator voltage inputs must be adjusted properly. See the
setpoint Vg InpRangeSel.
