Subject to change without notice
If the minimum distance is calculated according to ISO 13855, then it depends on the
following points:
•
Machine stopping time (time interval between triggering the sensor function and
the end of the dangerous state of the machine)
•
Response time of the protective device,
• Reach or approach speed of the person
• Resolution (detection capability) of the safety light curtain
• Type of approach: Orthogonal or parallel.
• Parameters specified based on the application
For the USA (scope of OSHA and ANSI), different regulations may apply, e.g.:
a) Laws: Code of Federal Regulations, Title 29 (CFR29) Part 1910.217
b) Standards: ANSI B11.19
NOTE
Additional information is available in the ISO 13855 standard and in the Guide for Safe
Machinery.
NOTE
SICK offers a stopping/run-down time measurement service in many countries.
