6.1.2 Multi-axis arrangement
Figure 6.1: With multi-axis installation, the light beams must run parallel to the reference plane (e.g.
floor) and must be aligned mutually parallel.
The beam directions are to be set oppositely in each case (See Figure 6.2:). Otherwise, the light beams
could cause mutual interference and disturb reliable function.

WARNING
Failure to maintain minimum distances to reflective surfaces may result in serious injury!
Reflective surfaces can indirectly deflect the transmitter beams to the receiver. In this case, inter
-
ruption of the protective field is not detected.
Make certain that all reflective surfaces are the necessary minimum distance away from the
protective field.
