Distance covered during the response time of the safety laser scanner
T
he 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
The response time T
S
of the safety laser scanner depends on the following factors:
•
Basic response time of the safety laser scanner
•
Set multiple sampling

or 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 t
o 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.

Protective field length
The lump supplement for ground clearance under 120 mm is 150 mm. This supple‐
ment may be reduced further in individual cases. The actual supplement required
based on the ground clearance of the vehicle can be read from the following graph:
