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.
►
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

= 350mm.
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 cover a minimum area so that the safety laser scanner
reliably detects a moving person:
•
The lower edge of the protective field must not be more than 300mm above the
floor/ground according to ISO13855.
•
Resolution <150mm: The top edge of the protective field must be at least
900mm above the floor/ground according to ISO13855.
•
Resolution 150mm: The top edge of the protective field must be at least
1,100mm above the floor/ground.
•
Resolution 200mm: The top edge of the protective field must be at least
1,400mm above the floor/ground.
The multiple sampling must be 2 or 3. Otherwise, a person could possibly walk unde‐
tected through the protective field.
