2.2.4 Use of deviating mirrors

Deviating mirrors can be used to monitor danger zones where access

is possible from various sides.

Fig. 10 illustrates a potential solution for monitoring three different

access sides using two deviating mirrors positioned at an angle of 45°

to the safety light curtain.

Please note the following precautions to take when using deviating

mirrors:

• The alignment of the emitter (TX) and receiver (RX) is particularly

critical when you use deviating mirrors; just a slight angular

displacement of the mirror is enough to lose the alignment. This

problem can be resolved by using a laser pointer, which is

available as an accessory.

• The minimum safety distance (S) must be maintained for each

section of the safety light curtain.

• Use of a deviating mirror reduces the effective operating range by

about 15%. If two or more deviating mirrors are used, the range will

be reduced still further (for more details please refer to the

technical specifications for the specific mirror).

• Never use more than three mirrors per device.

• Any dust or dirt on the mirror’s reflective surface will drastically

reduce the operating range.
