Installation
Î On mounting, make sure that 300 mm or
more clearance is kept above the enclo-
sure cover.
5.2 Preparation for installation
Before installation, make sure the following
conditions are met:
− The position transmitter is not damaged.
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during installation
work.
Î Put the control valve out of operation by
disconnecting and locking the supply
and control signal.
Î Adjust correct lever and pin position (see
section 5.2.1).
5.2.1
Lever and pin position
The position transmitter is adapted to the
actuator and to the rated travel by the lever
on the bottom of the position transmitter and
the pin inserted into the lever. The travel
tables show the maximum adjustment range
at the position transmitter.
The travel that can be implemented at the
valve is additionally restricted by the re-
quired compression of the actuator springs.
If a pin position other than position 35 with
the standard M lever is required or a differ-
ent lever size is required, proceed as follows
(see Fig. 5-1):

Î Do not remove the tab washer (1.3).
2. Remove the follower pin (2) from its pin
position and move it to the hole for the
recommended pin position (according to
travel tables) and screw tight. Only use
the longer follower pin included in the
mounting kit.
3. Place the lever (1) on the shaft of the po-
sition transmitter and fasten it tight using
