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 the figure must be avoided:

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.
The figure shows a possible solution to control two different access sides, using one mir
-
ror placed at 45° with respect to the beams.
Figure 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 Datasensing laser pointer accessory is recommended under these con
-
ditions.
• The minimum safety distance (S) must be respected for each single section of the
beams.
• The effective operating range decreases by about 20% by using only one deviating
mirror.
The following table shows estimated operating distances relating to the number of mir
-
rors used.
• The presence of dust or dirt on the reflecting surface of the mirror causes a drastic
reduction in the range.
