Figure 7: Mounting lever and bracket on the positioner
1.
 Attach the lever
6
to the feedback shaft
5
of the
positioner (can only be mounted in one position due to the
cut shape of the feedback shaft).
2.  Using the arrow marks
4
, check whether the lever moves
within the operating range (between the arrows).
3.  Hand-tighten the screw
7
on the lever.
4.  Hold the prepared positioner (with the mount bracket
1
still
loose) on the actuator so that the follower pin for the lever
enters the follower guide to determine which tap holes on
the positioner must be used for the mount bracket.
5.  Secure the mount bracket
1
with screws
2
and washers
3
using the relevant tap holes on the positioner housing.
 Tighten the screws as evenly as possible to ensure
subsequent linearity. Align the mount bracket in the oblong
hole to ensure that the operating range is symmetrical (lever
moves between the arrow marks
4
).
