ries: Table 7 on page 52
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 sec-
tions 5.1 and 5.2 apply for the
pneumatic and electrical connec-
tion.
Operation and setting are described
in sections 7 and 8.
−
Since 2009, the back of the posi -
tion sensor (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 pur
-
pose. See Table 7.
