6.8 Ambient conditions
} Information given in the Technical details [ 127] must be followed.
} If there is a highly reflective background within a distance of 2.5 m from the safety zone
perimeter (e.g. a shiny metallic surface), errors in the calculation of the exact distance to
the detected object may occur.
– Reduce the reflection of the background or remove the background or
– add the allowance Z
R
to the minimum safety distance (see Distance to intense light
sources and to reflective surfaces [ 50]).
} Avoid strong electromagnetic interference when operating the safety laser scanner.
} When operating the safety laser scanner, avoid strong smoke, mist, and dust formation
that would reduce the safety laser scanner's operating range or lead to switching to the
OFF state.
} In the safety laser scanner's overall scanning plane, avoid fixed objects that impede mon-
itoring of the safety zone.
6.9 Distance to intense light sources and to reflective surfaces
Minimum distance to especially intense or flashing light sources
Pilz recommends that the safety laser scanner is not installed near particularly intense or
flashing light sources (e.g. flash units).
When especially intense or flashing light sources are near the safety laser scanner (area of
+/-5° to the scanning plane, see figure), an allowance has to be considered when calculat-
ing the safety distance.
