Minimum distance from reflective surfaces
} Pilz recommends that reflective surfaces with a distance of 3 m to the safety zone are re-
moved.
If this is not possible, the allowance Z
R
must be considered when calculating the safety
distance.
(The recommendation was determined with a background reflection of 300
cd
m
2
lx
*
. For
highly reflective backgrounds an additional safety assessment is required, taking into ac-
count the reflective background. This may result in a higher allowance.)
} Objects that may be influenced by safety laser scanners through ambient light, must not
be placed within the opening angle of the laser beam.
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 [ 29].
The value for the allowance Z
R
depends on the selected level of the dust filter.

INFORMATION
Determining of the allowance when the safety laser scanner has to be
installed near particularly intense or flashing light sources and a re-
flective background.
Use the higher value of the relevant allowances.
