7. Install the mounting bracket ① at the rear side of the positioner. For this purpose, use:
– Two hexagon bolts ⑨
– Spring lock washer ⑩
– Flat washer ⑪
8. Select the row of holes. The selection of the row of holes depends on the yoke width of
the actuator. Select the row of holes such that the carrier pin ④ meshes with the pick-up
bracket ② near the spindle. Ensure that the pick-up bracket does not touch the clamping
pieces.
9. Keep the positioner and the fastening bracket on the actuator. Ensure that the carrier pin
④ is guided inside the pick-up bracket ②.
10. Tighten the pick-up bracket.
11. Fasten the positioner on the yoke. Use the installation parts suitable for the
corresponding actuator.
Note
Height adjustment of the positioner
When you fasten the positioner on the yoke, the following applies for its height
adjustment:
1. Set the height of the positioner such that the horizontal lever position is near the
center of the stroke.
2. Orient yourself by the lever scale of the actuator.
3. If symmetrical mounting is not possible, you must always ensure that the horizontal
lever position is maintained within the range of stroke.
