S
Minimum distance in mm, measured from the start of the protective zone to the
danger source
K
Approach speed with which the object to be detected is nearing the danger zone in
mm/s
K = 1600 mm/s when S > 500 mm
K = 2000 mm/s when S ≤ 500 mm
t
1
Overall response time of the safety laser scanner in seconds (see
)
Time between the violation of a protective zone and signal change at the OSSD out-
put on the safety laser scanner
t
2
Machine's stopping time in seconds
The time required for the machine to stop after the signal at the OSSD output
changes
C
Additional distance depending on the height of the scanning plane and the detection
capability
Z
T
General safety allowance = 100 mm
Z
R
Allowance when installing near intense light sources or reflective surfaces (see
tance to intense light sources and to reflective surfaces [
Determining the additional distance C depending on the height of the scanning plane
and the detection capability (see EN ISO 13855)
C = (1200 -0.4H)
Please note:
}
Permitted height H of the scanning plane
– H ≥ 15(d-50)
d = Resolution (see
)
– Max. 1000 mm
}
When the safety laser scanner is to be placed at a height of H > 300 mm, there is a risk of
creeping underneath the safety zone. This is to be taken into account in the risk assess-
ment, and if required additional protective measures must be taken.
