Mounting and start-up
5.11 Mounting the leakage
sensor
Î
See Fig. 29
Normally, the control valve is delivered with
positioner and leakage sensor already
mounted.
If the leakage sensor is mounted after the
valve has been installed or it is mounted on-
to another control valve, proceed as de-
scribed in the following.
Risk of malfunction due to incorrect fasten-
ing!
Fasten the leakage sensor using a torque of
20 ±5 Nm.
The M8 threaded connection on the NAMUR
rib should preferably be used to mount the
sensor (Fig. 29).
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 sen -
sor.
The start-up of the leakage sensor is de-
scribed in detail in the Operating Instructions
for EXPERTplus Valve Diagnostics.
