b
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
In a s
tationary application, for example on a machine where the point of access to the
hazardous area can be physically defined, the safety laser scanner is mounted with a
vertical scan plane. 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
H
azard 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
during 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).
