Caution
Despite switched-off compressed air supply – dependent on the product variant – one
or both working ports of the positioner can remain under pressure.
• Vent the working ports with the help of the Sensor function (menu 1) before you
remove the tubing lines (è Section 7.6.5).
Note
Use suitable fittings (G1/8) and tubes.
Recommendation: Push-in fittings of type QS-1/8-...-I and tubes of type PUN.
Prior to the pneumatic installation:
1. Ensure there is no voltage or pressure applied.
2. Secure the system against being switched back on.
