Distance covered during the response time of the safety laser scanner
The distance covered during the response time of the safety laser scanner depends on
the following factors:
•
Response time of the safety laser scanner
•
Maximum speed of the vehicle in the mobile application
S
of the safety laser scanner depends on the following factors:
•
Basic response time of the safety laser scanner
•
Set multiple sampling
•
Transmission speed to external OSSDs via EFI

Supplement Z
R
for reflection-related measurement errors
For retro-reflectors in the background less than 1 m from the protective field boundary,
the supplement Z
R
is 200 mm.
Supplement Z
F
due to lack of ground clearance
This supplement is necessary, because, generally, a person is detected above the foot
and the braking process cannot take account of the length of the foot in front of the
point of detection. A person’s foot could be injured if a vehicle has no ground clearance.
