Installation of external accessories

To protect the end positions against uncontrolled overrunning:
• Check whether proximity sensors are necessary (hardware limit switches).
If proximity sensors are used as limit switches:
• Preferably use proximity switches with normally-closed function.
These will protect against overrunning of the end position in an EGC with a fractured proximity
switch cable.
If proximity sensors are used as reference switches:
• Use proximity sensors that correspond to the input of the controller being used.
• Use inductive proximity switches with switch lug aE (
used).

• Avoid external influences from magnetic or ferritic parts in the vicinity of the proximity switches
(minimum distance of 10 mm from the slot nuts).
To protect the end positions:
• Use emergency buffer (
To prevent contamination:
• Use groove covers in all unused grooves.
