5.4.8.3 Sample calculation of the depth of a detection zone
This example is based on the following application data (see 5.4-5):
The formula
S = ( K × ( T
SCAN
+ T
MACH
+ ( T
LAG
× L
LAG
))) + C
results in a safety distance of:
S = (1,600mm/s × (0.08s + 0.1s + (0.5s × 1.1))) + 1,080mm = 2,248mm
The formula
S
T
= S + Z
SM
+ Z
AU
results in the detection zone depth:
S
T
= 2,248mm + 83mm + 125mm = 2,456mm
Largest width between the axis of
the rotating mirror and the
boundary of the danger zone
G
BDIFF
700mm
Access speed
K
1,600mm/s (constant)
Response time of the
SD3-A1
(adjustable)
T
SCAN
0.08s
Response time of the machine or
system
T
MACH
0.1s
Stopping time or lag time of the
machine or system
T
LAG
0.5s (time for braking the
dangerous movement until
standstill)
Factor for increase in lag time
L
LAG
1.1 (fixed addition to account for
increased lag time)
Addition for system-specific
measurement error
Z
SM
83mm (when dust algorithm is
switched OFF)
Addition caused by the mounting
position that is selected
Z
AU
125mm (distance between the
front edge of the undercut to the
beam axis of the scanner)
Height of the sensor
scanning plane
H
300mm
Safety-related constant
C
1,200mm – 0.4 × Height H
= 1,080mm
