2.
Slide the pick-up bracket ② into the notches of clamping pieces. Set the required length
and tighten the bolts such that the pick-up bracket can still be moved.
3.
Insert the pre-installed pin ④ in the lever ⑥. Install the lever with the washer ⑫ and the
spring lock washer ⑭.
4.
Set the stroke value. Use the value specified on the type plate of the actuator for this
purpose. If none of the values on the scale matches the value on the type plate of the
actuator, select the next higher scaling value. Position the pin center on the matching
value on the scale. If you need the value of actuator travel after initialization in mm:
ensure that the set stroke value matches the value of the "3.YWAY" parameter.
5.
Install the following parts on the lever:
–
Hexagon bolt ⑰
–
Spring lock washer ⑯
–
Washer ⑫
–
Square nut ⑲
6.
Push the pre-installed lever up to the end stop on the positioner shaft. Fix the lever using
a hexagon bolt ⑰.
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.
