Minimum distance S
A
ccording to ISO 13855 and ISO 13857, the minimum distance S depends on the:
•
Stopping time of the machine or system. The machine stopping/run-down time
can be obtained from the machine documentation or must be determined by mea‐
surement.
•
Response time of the safety laser scanner
•
Reach or approach speed
•
Resolution of the safety laser scanner
Calculate the minimum distance S using the following formula (see ISO 13855):
•
S = 2,000 × (T
M
+ T
S
) + 8 × (d – 14) [mm]
