Important information
DANGER
Hazard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
The safety laser scanner is not suitable for finger detection, because the finest resolu‐
tion is 30 mm.
b
Never use the safety laser scanner for applications in which finger detection has to
be realized.
b
Use the contour of the environment as a reference to protect the protective device
from inadvertent adjustment or tampering (
see "Reference contour monitoring",
).
DANGER
Hazard due to lack of effectiveness of the protective device
If there is a retroreflector in the protective field level (distance of the retroreflector from
protective field ≤ 6 m), it may not be possible detect people and parts of the body that
are to be protected, or it may not be possible to detect them on time.
b
Avoid retroreflectors in the protective field level if possible.
b
With retroreflectors at the protective field level: Increase overrun of the protective
field over the opening to be protected by supplement Z
R
= 350 mm.
DANGER
Hazard due to lack of effectiveness of the protective device
Devices with max. protective field range of 9 m: Strongly reflective surfaces (e.g. shiny
metal, tile) with a distance from the protective field ≤ 6 m can behave similarly to a
retroreflector if the laser beam hits the surface vertically. If the protective field is larger
than 50% of the effective protective field range in the direction of the laser beam which
is hitting the surface vertically, it is possible that persons and parts of the body that are
to be protected will not be detected or not be detected on time.
b
Avoid strongly reflective surfaces in the protective field level if possible.
b
With strongly reflective surfaces in the protective field level: Increase overrun of
the protective field over the opening to be protected by supplement Z
R
= 350 mm.
The protective field must be designed so that it detects access by a person at a
minimum distance from the hazardous point. This distance is required to prevent a
person or part of their body from reaching the hazardous area before the end of the
machine’s dangerous state.
In hazardous area protection, the minimum distance typically defines the position at
which the safety laser scanner is mounted.
In many cases, a resolution of 30
mm or 40
mm is suitable for hazardous point
protection.
