Use Of Deviating Mirrors - Pilz PSEN opII3B Series Operating Manual

PSEN opII3B Series
An arrangement of the adjacent safety light curtains can be achieved by various methods.

Use of deviating mirrors

Danger zones with different but adjacent access sides can be monitored using a safety light
curtain in conjunction with
The diagram below shows an example solution for monitoring three different access sides
using two deviating mirrors. The deviating mirrors must be positioned at an angle of 45° to
the beams from the safety light curtain.
When using deviating mirrors, please note:
}
Even a minor angular displacement of the mirror can lead to misalignment, adversely af-
fecting or preventing the function of the safety light curtain. Use the laser pointer PSEN
opII for alignment (see
} The minimum safety distance to the dander zone must be maintained for all sections of
the light path.
} The use of a single deviating mirror reduces the operating range (the degree of reduction
is specified in the technical details of the used mirrors). This percentage increases when
an additional deviating mirror is used. Please consider this reduction when positioning the
safety light curtain.
} You should not use more than two mirrors per device.
}
Any dust or dirt on the mirror's reflective surface will drastically reduce the operating
range.

Extension of the response time of the safety light curtain when using
the beam coding
When calculating the safety distance, remember the extended response
time (see Technical details [
Changing from uncoded to coded operation is a change of the safety light
