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):
Largest width between the axis of
the rotating mirror and the
boundary of the danger zone
Access speed
Response time of the SIMATIC
FS600 Laser Scanner
(adjustable)
Response time of the machine or
system
Stopping time or lag time of the
machine or system
Factor for increase in lag time
Addition for system-specific
measurement error
Addition caused by the mounting
position that is selected
Height of the sensor
scanning plane
Safety-related constant
The formula
S = ( K x ( T
results in a safety distance of:
S = (1600 mm/s * (0.08 s + 0.1 s + (0.5 s * 1.1))) + 1080 mm = 2248 mm
The formula
S
= S + Z

SM
results in the detection zone depth:

= 2248 mm + 83 mm + 125 mm = 2456 mm
