Use of deviating mirrors
Hazardous areas with different but adjacent access sides can be monitored using a safety
light grid 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 grid.
When using deviating mirrors, please note:
}
Even a minor angular displacement of the mirror can lead to misalignment, adversely
affecting or preventing the function of the safety light grid. Use the laser pointer PSEN
opII for alignment (see
Order reference for accessories [
).
}
The minimum safety distance to the hazardous area must be maintained for all sections
of the light path.
}
Use of a single deviating mirror reduces the operating range by about 20%. This per-
centage increases when an additional deviating mirror is used (more detailed informa-
tion is provided in the technical data for the relevant mirror). Please consider this reduc-
tion when positioning the safety light grid.
}
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.
