8. Mount the bracket ① to the NCS mounting kit using:
– Two hexagonal screws ⑧
– Spring washer ⑨
– Washer ⑩
– Hexagonal nut ⑰
The selection of the row of holes depends on the yoke width of the actuator. Make sure that
the dog pin ④ engages in the pick-up bracket ② as close as possible to the spindle over
the complete stroke range. The dog pin must not touch the clamping pieces.
9. Place the NCS assembly kit with the mounting bracket ① onto the actuator. Ensure that the
dog pin ④ is guided inside the pick-up bracket ②.
10.Tighten the pick-up bracket ② .
11.Prepare the assembly parts for the relevant actuator type for installation:
– For mounting on yoke with fin: hexagonal screw ⑦, washer ⑩ and spring washer ⑨.
– For mounting on a yoke with plane surface: Four hexagonal screw ⑦ with washer ⑩
and spring washer ⑨.
– For actuator with columns: Two U brackets ⑥, four hexagonal screw ⑰ with washer ⑩
and spring washer ⑨.
12.Mount the NCS assembly kit to the yoke using the assembly parts that you prepared.
Note
Observe the height
Adjust the height of the NCS assembly kit so that the lever position is in line horizontally with
the stroke center. Use the lever scale on the actuator for orientation. If a symmetrical
assembly is not possible, you must always ensure that the lever is in horizontal position
within the range of the stroke.
