Electronic position transmitter RWG: set

SAR 16.1
— Option —
The potentiometer as travel sensor records the valve position.
Due to the ratio of the reduction gearing the complete resistance range/stroke is not
always passed. Therefore, external adjustment (setting potentiometer) must be pro-
vided.

1. Move valve to end position CLOSED.
2. Turn potentiometer [1] clockwise to the stop.
End position CLOSED corresponds to 0 %
End position OPEN corresponds to 100 %
3. Turn potentiometer [1] slightly in opposite direction.
4. Perform fine-tuning of the zero point at external setting potentiometer (for remote
indication).
— Option —
The electronic position transmitter RWG records the valve position. On the basis of
the actual position value measured by the potentiometer (travel sensor), it generates
a current signal between 0
