Hazardous point protection

Subject to change without notice
Overview
The safety laser scanner is mounted with a vertical scan plane in a stationary applica‐
tion, for example on a machine where the operator must stay close to the hazardous
point. A fixed barrier with a height of at least 1200 mm is located in front of the haz‐
ardous point. The operator can reach over the barrier and through the scan plane into
the hazardous point. But the operator cannot climb over the barrier. If there is no such
barrier available, access protection may be required.
During hazardous point protection, the safety laser scanner detects a person's hand or
other part of their body. The protective field is orthogonal to the direction of approach of
the body part. A resolution of 40 mm or finer is required to ensure detection of the
hand during hazardous point protection.

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.
Never use the safety laser scanner for applications in which finger detection has to
b
be realized.
Use the contour of the environment as a reference to protect the protective device
b
from inadvertent adjustment or tampering
