Use of deviating mirrors

Deviating mirrors can be used to monitor danger zones where access
is possible from various sides.
Fig. 11 illustrates a potential solution for monitoring three different
access sides using two deviating mirrors positioned at an angle of 45°
to the light curtain.
Please note the following when using deviating mirrors:
•
The alignment of the transmitter and receiver is particularly critical
when you use deviating mirrors; just a slight lateral displacement of
the mirror is enough to lose the alignment.
•
The minimum safety distance (S) must be maintained on all access
sides.
•
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.
