azard 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.

With retroreflectors at the protective field level: Increase overrun of the protective
field over the opening to be protected by supplement Z

4.3.9.1 Protective field
In access protection, the minimum distance typically defines the position at which the
s
afety laser scanner is mounted.
The protective field must be at least 900 mm high so that it is not possible to climb
over it.
The multiple evaluation must be 2 or 3. Otherwise, a person could possibly walk unde‐
tected through the protective field.
4.3.9.2 Calculation example for the minimum distance
Calculation example of the minimum distance S according to ISO 13855
T
he example shows the calculation of the minimum distance for an orthogonal
approach to the protective field. A different calculation may be required, depending on
the application and the ambient conditions (e.g. for a protective field parallel to or at
any angle to the direction of approach or an indirect approach).
S = 1,600 mm/s × T +850 mm
