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

4.3.8.1 Protective field
In hazardous area protection, the minimum distance typically defines the position at
whic
h the safety laser scanner is mounted. Access to the hazardous point shall only be
possible through the protective field.
In many cases, a resolution of 20mm, 30mm or 40mm is suitable for hazardous point
protection. A resolution of 40mm or finer is required to ensure detection of the hand
during hazardous point protection. The safety laser scanner is not suitable for finger
detection, because the finest resolution is 20mm.
Complementary information
T
he required minimum distance depends on the safety laser scanner’s set resolution.
Notes on selecting the resolution:
•
If you choose a fine resolution, the protective field range is smaller and the
protective field is only suitable for smaller hazardous points. But the required
minimum distance is smaller, you can mount the safety laser scanner closer to the
hazardous point.
•
If you choose a coarser resolution, the protective field range is larger and the pro‐
tective field is also suitable for larger hazardous points. But the required minimum
distance is larger, you must mount the safety laser scanner further away from the
hazardous point.
