Required mounting parts and accesso-
ries: Table 8 on page Seite 25.
In the positioner version with an external
position sensor, the sensor located in a
separate housing is attached over a plate or
bracket to the control valve. The travel pick-
off corresponds 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 brack-
et (7) must be fixed to the housing, depend -
ing on the accessory chosen. Make sure the
seals (6.1) are correctly inserted (see Fig. 9,
bottom right).
For the electrical connection a 10 meter
connecting lead with M12x1 connectors is
included in the scope of delivery.
