MOUNTING AND OPTICAL ALIGNMENT

The emitter and the receiver must be installed opposite each other. The

distance between the emitter and the receiver must not exceed the specified

nominal scanning range. Brackets are delivered with AS emitter and

receiver units. The emitter and the receiver should be parallel in the same

plane, at the same height and with connectors on the same side.

Emitter and receiver modules are equipped with M6 screws (see Dimen-

sions) fixed at the back of the housing. These M6 screws can be used either

for direct mounting with the provided nuts, or in conjunction with brackets

(see figure 15 and figure 16).

The optimum optical alignment between emitter and receiver is essential

for the correct operation of the system. The emitter and the receiver are

equipped with LED’s which help adjust the optical alignment.

To achieve an optimum alignment, the optical axis of the outer beams of

both emitter and receiver must mix up.

Install the receiver and adjust the emitter as follows:

• Adjustment of the synchronisation beam: sight the emitter in

direction of the receiver. Then move the emitter from top to bottom

and from left to right in order to find extreme positions of the

synchronisation beam for which the green LED of the emitter

switches off. This green LED provides information on the synchro-

nisation beam reception. The optimum position is the intermediary

position between extreme positions.

• Adjustment of protective beams: use the synchronisation beam as

a pivot and move laterally the opposite outer beam in order to

find the extreme positions, for which the yellow LED of the receiver

switches off. The optimum position is the intermediary position

between extreme positions.
