2.2.3 Aligning transmitter and receiver
The light curtain pair must be arranged in parallel to each other. Transmitter and receiver
have connections underneath. Both units must be installed at the same time.
Make sure that the light curtains are not configured as shown in Fig. 14.

2.2.4 Using deviating mirrors
If a single safety device is used, danger zones with different but adjacent access sides can
be monitored using well-positioned deviating mirrors.
Fig. 15 shows a possible solution, which can be used to protect three access sides using two
mirrors. The deviating mirrors should be positioned at a 45° angle to the light axes.
Fig. 15- Using deviating mirrors
When deviating mirrors are used, the following precautions must be taken and conditions
considered:
• When deviating mirrors are used, the alignment of the transmitters and receivers requires
higher precision. Perfect alignment can be lost even with only a minor angular displacement of
the mirror. In this case we recommend you use the laser pointer, which is available as a
n
a
ccessory.
• The minimum safety distance (S) must be maintained for all sections of the beam.
• Use of a single deviating mirror reduces the effective operating range by about 15%. This
percentage increases when two or more deviating mirrors are used (more detailed informati
on
i
s provided in the technical specifications for the relevant mirror).
