Positioner (OPTION)
The potentiometer used for actuator
signal feedback is driven by position
indicator rod.
For clockwise closing:
• 0% position indicates a closed valve
• 100% position indicates an open
valve.
Resistance value is measured between 16 and 17 terminals.
How to set potentiometer
You can set the zero of the potentiometer with the 0% position
screw. Use a flat blade screwdriver to turn this screw.
1. Drive the actuator to the CLOSED position.
2. Hold the pinion located just under the plate marked with the
0% position while turning the potentiometer screw.
3. Adjust the potentiometer so that the resistance value exceeds
0 Ohm and regularly increases then turn backwards to reach
the closest value to 0 Ohm.
4. Drive the actuator to the OPEN position and write down the
resistance value corresponding to the 100% position.
5. Come back to the CLOSED position and check that the
resistance shows a repeatable near zero value for the 0%
position.
Signal inversion
To change the signal variation direction, invert
potentiometer wires on the terminal block (e.g. for a
connection on 16/17/18, invert 16 and 18).
