If t
he result is S > 500 mm, you may be able to reduce the minimum distance
using the following calculation:
S = 1600 mm/s × T + 8 ×(d – 14 mm)
✓
If t
he new value is S > 500 mm, use the newly calculated value as the minimum
distance.
✓
If the new value S is ≤ 500 mm, then use 500 mm as the minimum distance.
4.3.8 Access protection
Overview
T
he safety laser scanner is mounted with a vertical scan plane in a stationary applica‐
tion, for example on a machine, for which access to the hazardous area may be defined
structurally. For access protection, the safety laser scanner detects an intrusion by a
whole body. The protective field is orthogonal to the person’s direction of approach.

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.
b
Use a resolution of 200 mm or finer. Otherwise, protection will not be ensured dur‐
ing access protection.
b
Use double sampling during access protection. Under certain circumstances, a
person could pass through the protective field without being detected when using
higher multiple sampling.
b
Use the contour of the environment as a reference to protect the protective device
from inadvertent adjustment or tampering (see "Reference contour monitoring",
page 30).
