Adjusting The Maximum Length Of Travel; Inductive Proximity Switches; Determining The Final Position - THOMSON WM60-370ZRT Instructions De Montage Et De Maintenance

Adjusting the maximum length of travel

Provide for sufficient overrun length for braking in case of emergency stop.
Electrical switches must be installed by trained electricians only.
Note circuit diagram on the limit switch.
4.3

Inductive proximity switches

Inductive proximity switches are used to cut off the electrical drive before the final position is
reached. The necessary stopping distance depends on the speed and the braking effort. This
braking distance must at least end between the switch point of the proximity switch and the
actual, mechanical end of position.
4.3.1

Determining the final position

The contact surface of the limit switch must be completely covered by the switch flag just
before the sliding carriage reaches the safety zone.
1. Fig 4: Release the proximity switch by loosening the attachment screw (1).
2. Move the proximity switch (2).
3. Fix the proximity switch in position by tightening the attachment screw. In doing so,
ensure that the proximity switch is fully locked into the profile groove.
4. Check the position of the limit switch moving the sliding carriage.
5. If necessary, repeat the procedure.
6. Attach the limit-switch profile cover.
