2.2.3 Emitter and Receiver Orientation
The two units shall be assembled parallel each other, with the beams arranged at right
angles with the emission and receiving surface, and with the connectors pointing to the same
direction.
The configurations shown in Fig. 14 must be avoided:
NO

2.2.4 Use of deviating mirrors
The control of any dangerous area, with several but adjacent access sides, is possible using
only one safety device and well-positioned deviating mirrors.
Fig. 15 shows a possible solution to control three different access sides, using two mirrors
placed at 45° with respect to the beams.
Fig. 15 – Use of deviating mirrors
The operator must respect the following precautions when using the deviating mirrors:
The alignment of the emitter and the receiver can be a very critical operation when
deviating mirrors are used. Even very small displacements of the mirror is enough to
lose alignment. The use of Datalogic laser pointer accessory is recommended under
these conditions
The minimum safety distance (S) must be respected for each single section of the
beams.
The effective operating range decreases by about 15% by using only one deviating
mirror, the percentage further decreases by using 2 or more mirrors (for more details
refer to the technical specifications of the mirrors used).
