ELGA-TB-G/-KF/-RF
5.1.3 Mount accessories
To protect the end positions against uncontrolled excess travel:
• 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 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).
• Use groove covers on all unused grooves to prevent contamination (è www.festo.com/catalogue).
Connection option for sealing air
• Connect sealing air. For this, remove threaded dowel
(5 è Fig. 14) from drive cover and connect up compressed
air / vacuum extraction. For additional protection, use other
sealing air connections. This is possible on both drive covers
on both sides.
