mounted.
If the leakage sensor is mounted after the
valve has been installed or it is mounted onto another control valve, proceed as described in following.

The M8 threaded connection on the NAMUR
rib should preferably be used to mount the
sensor (Fig. 19).
Tip:
If the positioner was mounted directly
onto the actuator (integral attachment), the NAMUR interfaces on either side of the valve yoke can be
used to mount the leakage sensor.
The start-up of the leakage sensor is described in detail in the Operating Instructions
