Cable Routing / Final Check
6.0 CABLE ROUTING
The most important and the most over looked aspect of fitting the linear encoder is proper cable routing. Dangling and loose cables can be snagged or broken causing irreparable damage. Care should be taken in order to ensure that the cables are secured to the machine and that cable loops do not interfere with any part of the machine or the linear encoder movements. “P” clips and thread forming screws are provided to route the cables from the reader head.
Note: The armored cable is an integral part of the reader head. If the cable becomes damaged, then it would have to be replaced complete with the reader head.
If extension cables are used, do not allow the plug and socket junction to lie in the swarf tray or in the direct flow of coolant or oil. Optional IP67 rated submergible connectors are available if required.
In order to avoid problems associated with electrical noise and interference, do not allow the cables to lie across electrical motors, fuse boxes or electrical pumps.
7.0 FINAL CHECK
Prior to putting the linear encoder into operation, slowly traverse the machine axis to both extents of its travel checking at all times that the cables are secure and that machine over travel cannot occur. Newall will not accept responsibility for linear encoder malfunction caused by over travel or damaged cables.
