Fig. 6
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. Refer to mounting table fig (tbc)
5. Secure the mount bracket 1 with screws 2 and washers 3 using the relevant tap holes on the positioner
housing. Refer to mounting table fig (tbc)
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 Set the valve mid stroke and align the lever horizontal
(item 4 Fig. 7) then tighten mounting bolt (item 4 Fig. 10) (lever moves between the arrow marks Item 4 Fig. 9).
