Important information
DANGER
H
azard due to lack of effectiveness of the protective device
It is possible to get around the protective device by crawling beneath.
b
Prevent people from being able to crawl beneath the protective field by mounting
the safety laser scanner appropriately.
b
If you mount the protective device higher than 300 mm, you must use additional
measures to prevent crawling beneath.
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.
b
Use a resolution of 70 mm or finer for hazardous area protection.
b
For hazardous area protection with a resolution of 70 mm: make sure that it is
possible to detect a human leg.
b
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).
b
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 33.
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
D
/15 + 50 mm
