4.1.2 Displacement sensor for rear-side mounting

The sensor for rear-side mounting is assembled with the help of a sensor holder which prefera-
bly includes an integrated bulkhead receptacle.
First determine the ideal length of the sensor holder. It should reach sufficiently far into the
machine inner such that the separation of the sensor holder together with sensor tip is not less
than the prescribed minimum (see adjustment):
1. Fix the displacement sensor using a retainer that is appropriate for the type of installation.
We recommend using the holder AC-101/AC-3101/AC-3101.

Assembling the driver (oscillator/demodulator)

Assemble either:
with assembly adapter on a hat-rail
•
with assembly adapter via screw mounting on a firm surface
•
The driver must be mounted electrically insulated on its mounting socket and inside a pro-
•
tective housing, because the driver housing is part of the instrinsically safe circuit.
The distance of the driver housing to adjacent drivers, or any other conductive part of the
•
housing, must always be above 2 mm. The mounting socket ensures that this minimum gap
is observed.
C
AUTION
The driver is category 2 equipment and must always be positioned outside
zone 0. In areas exposed to explosion hazards, it may only be connected to an
intrinsically safe supply circuit (Ex ia IIC).
