MECHANICAL ASSEMBLY AND OPTIC ALIGNMENT
The Emitter and the Receiver must be assembled opposite each other. Use the fastening
brackets and inserts supplied with the system to place the Emitter and the Receiver so that
these are aligned and parallel to each other and with the connectors facing the same way.
Perfect alignment of the Emitter and Receiver is essential in order to assure correct barrier
operation. The indicator LEDs on the Emitter and Receiver facilitate this operation.

•
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 find the area within which the green LED on the
Receiver stays on, then position the first beam of the Emitter (the one close to
the indicator LEDs) in the centre of this area.
•
Using this beam as a pivot, effect small sideways movements within the
protected area. The green LED on the Receiver will light up if the protected
area is clear.
•
Lock the Emitter and Receiver in place.
During these operations it may be useful to check the
yellow weak signal LED
on the
Receiver. Upon completion of alignment, this LED must be off.
If the Emitter and the Receiver are assembled in areas that are subject to strong vibrations,
the use of vibration-damping supports is recommended, in order to prevent circuit
malfunctions.
