CAUTION: In any case where bright light is present outside the ±5° range, the additional distance is still
highly recommended.
3.2.4 Highly Reflective Backgrounds
If there is a highly reflective background within 3 meters of the safety zone boundary, for example a metallic glossy surface,
the SX5 Safety Laser Scanner might fail to recognize the exact distance of the detected object.
In this situation, it is recommended to reduce or remove the reflecting background. See
Figure 21
on page 26 and
Figure 22
on page 26.

CAUTION: In all applications where highly reflective backgrounds within 3 meters of the Safety Zone
boundary cannot be avoided, an additional distance must be applied to the Minimum Safety Distance
calculations. This distance also depends on the Dust Filter Level setting. See the additional distance
charts (in
Light Interference
on page 26), minimum safety distance calculation section (
Minimum Safety
(Separation) Distance Formula
on page 30), and the dust filtering section (
Dust Filtering
on page 28).
3.2.5 Limited Detection Capability Zone
If the safety laser scanner is positioned in a limited detection capability zone, the device may not detect an object with low
reflectance
located at a distance of 100 mm or less from the safety zone origin (center of the scanner). This is the zone with
limited detection capability.
In this circumstance, it is recommended to make the risk assessment take into account the possibility that an object can
cross a zone with limited detection capability. If possible, responsible personnel must provide an additional solution.
