Important information
DANGER

azard due to lack of effectiveness of the protective device
It is possible to get around the protective device by crawling beneath.
►
Prevent people from being able to crawl beneath the protective field by mounting
the safety laser scanner appropriately.
►
If you mount the protective device higher than 300mm, you must use additional
measures to prevent people crawling underneath.
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.
Body parts to be protected may not be detected under coarse resolution.
►
Use a resolution of 70mm or finer for hazardous area protection.
►
For hazardous area protection with a resolution of 70mm:make sure that it is
possible to detect a human leg.
►
For hazardous area protection with a resolution of 70mm:mount the safety laser
scanner at a height of at least 300mm (height of the scan plane).
►
If it is not possible to mount the safety laser scanner at a height of at least
300mm, use a finer resolution, see "Calculating required resolution", page 39.
Calculating required resolution
If the height of the protective field (scan plane) is predefined and is less than 300mm,
you can calculate the required resolution using the following formula:
d
r
= H
