Since the sensor operates inductively, the switching surface must have a specific distance from the contact plate. This so-called "switching dis- tance" amounts to 0.5 ±0.1 mm.

￿Move the carriage until the contact plate is above the sensor holder.

￿Slide the sensor through the sensor holder opening until the switch- ing distance has been reached.

Measure the distance using a feeler gauge.

￿Tighten screw (2).

￿Finally, check the switching distance with the feeler gauge.

The slot (1) can hold up to 3 sensor cables. Suitable slot covers are available on request.

￿ Route the sensor cable in the slot.

4.2.5Mounting the motor or the gearbox

The motor or the gearbox are coupled by means of a preloaded elatomer coupling.

The motor or the gearbox can be mounted in different arrangements (turned in increments of 4 x 90°).

Unless otherwise specified, the standard tightening torques indicated on page 47 apply.

Table 4.2 Tightening torques and mounting dimensions clamping hub

Before mounting See chapter 7 "Accessories and spare parts" for suitable elastomer cou- plings (elastomer spiders, clamping hubs).

You need a set of Allen keys and a torque wrench with hexagon socket.

￿Clean all parts you will use.

￿Check all parts for damage; repair damages.

NOTE: Polluted or damaged parts may cause run-out which has an ad- verse effect on the service life of the elastomer coupling and the linear axis.
