Mount 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 excess travel beyond 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 (è Mounting instructions of the accessory).

• Avoid external influences from magnetic or ferritic parts in the vicinity of the proximity sensors (min­
imum distance of 10 mm from the slot nuts).
• Avoid contamination:
– Use slot covers in all unused slots
(è www.festo.com/catalogue).
– Connect sealing air. To do this, remove the threaded pin
(9 è Fig. 12) on the cover and connect compressed air/
vacuum.
