Installation of several adjacent safety light grids
An arrangement of several adjacent safety light grids can be achieved by various methods.
When installing of several adjacent safety light grids, note the

Use of deviating mirrors
Danger zones 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.
The minimum safety distance to the dander zone 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.
