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 (è Assembly instructions of the accessory
used).
Mounting
in the grooves aB (è Fig. 1)
Tab. 4
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 (è Assembly instructions of the emergency buffer).
To prevent contamination:
Use groove covers in all unused grooves.
