Proximity switches adjustment
j. Proximity switches adjustment
The following description is related to Amiad Standard Proximity Switches. Different types of Proximity
Switches may have different features but should work with the same principals.
Note: The proximity switch is NC (Normally Closed) conductive and illuminating as long as it is far from
the Activating Plate.
1. Rotate Drive Shaft counterclockwise (moving up) until it stops. Then rotate half-of-a-turn back.
2. Place the Upper switch in the highest hole of the Proximity Switch Bracket that DOES NOT illuminate.
This is the upper position in which the switch should be locked.
3. Lock the switch by means of two 17mm wrenches. Verify once again gap of 2 mm. Use Loctite 243 to
lock the Nuts.
4. Move transmission gear a few turns downward, then raise it again until switch is de-actuated (stop
illuminating).
5. Measure the height from the Cardan Joint lower surface (5.1) to the surface of the nearest Sealing
Bushing (H). [H minus 71mm] should be the height of the Cardan Joint when at the lower position (h).
See example below.
6. Rotate the Drive Shaft clockwise (moving down) until height is equal to the calculated "h".
7. Place the Lower switch in the lowest hole of the Proximity Switch Bracket that DOES NOT illuminate.
This is the lower position in which the switch should be locked.
8. Lock the switch by means of two 17mm wrenches. Verify once again a gap of 2 mm. Use Loctite 243.
9. Move transmission gear a few turns upward and then lower it again until switch is de-actuated (stop
illuminating).
10. Insert the Key (2.3) into the Drive Shaft Keyway and apply some grease.
11. Slide Drive Unit along Drive Shaft. Connect Drive Unit to red transmission.
12. When ready and safe, activate the Motor in both directions and verify correct functioning.
