AUMA SG 05.1-F05 - Electronic Position Transmitter RWG: Set; Mechanical Position Indicator: Set

3. Turn potentiometer [1] slightly in opposite direction.
4. Perform fine-tuning of the zero point at external setting potentiometer (for remote
indication).
9.13 Electronic position transmitter RWG: set
— 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 – 20 mA or 4 – 20 mA.

1. Connect voltage to electronic position transmitter.
2. Move valve to end position CLOSED.
3. Connect ammeter for 0 – 20 mA to measuring points [4 and 5].
4. Turn potentiometer [1] counterclockwise to the stop.
5. Turn potentiometer [1] slightly in opposite direction.
6. Turn potentiometer [2] clockwise until output current starts to increase.
7. Turn potentiometer [2] in opposite direction until the following value is reached:
- for 0 – 20 mA approx. 0.1 mA
- for 4 – 20 mA approx. 4.1 mA
➥
This ensures that the signal remains above the dead and live zero point.
8. Move valve to end position OPEN.
9. Set potentiometer [3] to end value 20 mA.
10. Approach end position CLOSED again and check minimum value (0.1 mA or
4.1 mA). If necessary, correct the setting.

1. Place indicator disc on shaft.
