Mechanical Assembly And Optical Alignment - Reer EOS2 A Manual

Mechanical assembly and optical alignment

The Emitter and Receiver must be installed facing each other, at a distance equal to or
less than that indicated in the technical data. Using the provided inserts and fastening
brackets, place the Emitter and Receiver so that they are aligned and parallel to each
other, and with the connectors facing the same side.
According to the dimensions and shape of the support to be used to install the Emitter
and Receiver, these must be mounted with the fastening inserts to the rear or inserting
these in the side spline (Figure 10).
Perfect alignment of the Emitter and Receiver is essential for efficient functioning of the
light curtain; this operation is facilitated observing the indicator leds of the Emitter and of
Receiver.
•
Position the optical axis of the first and last beam of the Emitter on the same axis
as that of the corresponding beams on the Receiver.
•
Move the Emitter in order to locate the area within which the green led on the
Receiver remains on, then position the first beam of the Emitter (that close to the
indicator led) at the centre of this area.
•
Using this beam as pivot, with minor movements of the opposite end, establish the
free protected area condition which, in this situation, will be indicated by lighting
up of the green led on the Receiver.
•
Lock the Emitter and the Receiver in place.
If the Emitter and Receiver are installed in areas subject to strong vibrations, vibration-
damping supports must be used (for the order code, see the ACCESSORIES/SPARES
paragraph) so as not to impair operation of the circuits.
