SICK safeVisionary2 - Supplement C with Orthogonal Approach to the Optical Axis, Access Protection; Supplement C with Parallel Approach to the Optical Axis, Access Protection

For protective fields extending >100cm, any multiple sampling setting can be
se
lected. For protective fields extending <100cm, the multiple sampling setting must
be no greater than 3. Otherwise a person could walk undetected through the protective
field.
4.3.12.2 Calculation example for the minimum distance
Overview
T
he following examples show the calculation of the minimum distance S for an
approach orthogonal or parallel to the optical axis (Z-axis) of the camera sensor. The
calculation is performed in accordance with ISO 13855 and the specific specifications
of the camera sensor. A different calculation may be required depending on the appli‐
cation and the ambient conditions, for example when approaching the optical axis of
the camera sensor at any angle.
Minimum distance S with orthogonal approach to the optical axis
S = 1,600mm/s × T + C
W
here:
•
S =minimum distance, in millimeters (mm)
•
T = stopping/run-down time for the entire system, in seconds (s)
(Response time of the device + machine’s stopping/run-down time, including
r
esponse time of the machine’s control system and signal propagation time)
•
C = supplement in millime
ters (mm)
The reach/approach speed is already included in the formula.
