Mounting and start-up
5.11 Mounting the leakage
sensor
Î RefertoFig.30
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 fastening.
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.30).
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.
