Installing the external accessories

To protect the end positions against uncontrolled overtravel:
• Check the necessity of proximity sensors (hardware limit switches).
If proximity sensors are used as limit switches:
• Preferably use proximity sensors with normally-closed function.
This protects against overtravel of the end position if the proximity sensor cable is broken.
If proximity switches are used as reference switches:
• Use proximity sensors that correspond to the input of the controller being used.
• Use proximity sensors with switch lug aJ (è Assembly instructions of the accessory).

• Avoid external influences from magnetic or ferritic parts in the vicinity of the proximity sensors
(minimum distance of 10 mm from the slot nuts).
• Avoid contamination and use slot covers in all unused slots.
