POTENTIOMETER
Allows to detect the actuator position in order to monitor the state of the valve.
The potentiometer is already adjusted when supplied; in the case a further adjustment is needed, please proceed as
follows:
- Isolate the actuator from electricity.
- Disconnect the position indicator.
- Loosen the lock screws of the potentiometer holder bracket.
- By using the manual drive lever, make the actuator rotate so to open the valve completely.
- Connect the terminals of an OHM meter to terminals 7 and 8 of the terminal board and manually adjust the potentio-
meter to the desired value.
- Reposition the potentiometer holder bracket and fasten the lock screws.
- Reinstall the position indicator, by making sure it matches with the state of the valve.
NOTE:
there are three resistance values available: 135, 500, 1000 Ohm.
