Attachment to the control valve – Mounting parts and accessories
4.7 Attachment of external po-
sition sensor
Positioner unit with sensor mounted on a mi-
cro-flow valve
− Required mounting parts and accessories:
Table 7 on page 54
In the positioner version with an external po-
sition sensor, the sensor located in a separate
housing is attached over a plate or bracket to
the control valve. The travel pick-off corre-
sponds to that of a standard device.
The positioner can be mounted as required to
a wall or a pipe.
For the pneumatic connection either a con-
necting plate (6) or a pressure gauge bracket
(7) must be fixed to the housing, depending
on the accessory chosen. Make sure the seals
(6.1) are correctly inserted (see Fig. 5, bot-
tom right).
For the electrical connection a 10 meter con-
necting lead with M12x1 connectors is in-
cluded in the scope of delivery.

Note
− In addition, the instructions in sections 5.1
and 5.2 apply for the pneumatic and elec-
trical connection.
Operation and setting are described in
sections 7 and 8.
− Since 2009, the back of the position sen-
sor (20) is fitted with two pins acting as
mechanical stops for the lever (1). If this
position sensor is mounted using old
mounting parts, two corresponding
Ø 8 mm holes must be drilled into the
mounting plate/bracket (21). A template is
available for this purpose. See Table 7.
