S = 1600 mm/s × T + 8 ×(d – 14 mm)
✓
If the 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.

Access protection
Overview
In a stationary 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
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
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",
).
