Figure 4-3 Mounting instructions for linear actuators with a stroke > 14 mm (0.55 inch)
Procedure
1. Mount the clamping pieces
③ to the actuator spindle using the hexagonal screw ⑭ and spring washers ⑬.
2. Slide the pick-up bracket
② into the milled recesses of the clamping pieces.
3. Set the necessary length.
4. Tighten the screws so that you can still shift the pick-up bracket.
5. Set the center of the pin
④ to the stroke range value specified on the actuator, or to the next higher scaling value. The
actuating distance in mm will be displayed on successful initialization if you set the same value at parameter "3.YWAY"
when commissioning the system.
6. Slide the lever
⑤ onto the shaft ⑱ up to the mechanical stop.
7. Secure the lever
⑤ using the hex socket head screw ⑲.
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. The dog pin ④ should engage in the pick-
up bracket (2) as close to the spindle as possible, but without contacting 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.
