4.3.1 Preparing Bracket for the positioner
Proper bracket must be made in order to adapt the positioner on the actuator yoke.
Please consider following important points when a bracket is being designed.

Positioner
’s feedback lever must be vertical to the valve stem at 50% of the valve stroke.

The connection bar of the actuator clamp for the feedback lever should be installed in
such a way that the valve stroke length coincides with the corresponding figure in
“mm”
marked on the feedback lever. Improper setting may cause poor linearity
4.3.2 Installation Steps
1. Assemble the positioner with the bracket made in previous step by fastening the bolts
(M8 * 1.25P).

DO NOT TIGHTEN THE BRACKET COMPLETELY.
3. Connect connection bar to the actuator clamp. The hole gap on the feedback lever is
6.5mm so the connection bar
’s outer diameter should be less than 6mm.
