Minimum distance from reflective surfaces
If there are reflective surfaces near the laser beams emitted from the safety laser scanner
(whether from above, below, or from the side), passive reflections can cause an object
within the safety zone to remain undetected.
}
Objects that may be influenced by safety laser scanners through ambient light, must not
be placed within the opening angle of the laser beam.
}
Pilz recommends that you install the safety laser scanner at a minimum distance of 2.5 m
to reflective surfaces. (The recommendation was determined with a background reflection
of 300
cd
m
2
lx
*
. For highly reflective backgrounds an additional safety assessment is re-
quired, taking into account the reflective background. This may result in a higher allow-
ance.)
Allowance Z
R
with distances below the recommended minimum distances to intense
light sources or reflective surfaces
If the recommended distances cannot be met, the allowance Z
R
must be considered when
calculating the safety distance [
.
The value for the allowance Z
R
depends on the selected level of the dust filter, on the selec-
ted detection capability and on the determined safety distance without this allowance.
