Assemble the supplied feedback lever, bracket and positioner
firmly, then loosely mount the assembly on the left hand side
of the actuator yoke. For central mount, mount on the right
hand side of the actuator yoke.

Make sure that Positioner’s feedback lever is perpendicular
to the valve stem at 50% of the valve stroke.
1.1.5
At 0% or 100% position, the linear lever or linear lever stopper should not touch the stopping bosses of positioner.

Refer to below and check the bolting positions of the
upper and lower brackets to be fastened depending on
the actuator’s stem height.
And then assemble the positioner with the brackets by
using M6 bolts, washers and nuts.

The feedback pin coming from the actuator coupling should
be inserted inside slot of the feedback lever in such a way
that the length of valve stroke coincides with the
corresponding figures in “mm” marked on the feedback lever.
Improper setting may cause poor linerarity or damage to
positioner.
