According to ISO 13855 and ISO 13857, the minimum distance S depends on the:
•
R
each or approach speed
•
Stopping time of the machine or system
(The machine stopping/run-down time can be obtained from the machine docu‐
mentation or must be determined by measurement. SICK Service can carry out a
stop time measurement on your system on request.)
•
Response time of the safety laser scanner
•
Supplement C to prevent reaching through
Minimum distance S
C
alculate the minimum distance S using the following formula (see ISO 13855):
b
S = (K × (T
M
+ T
S
)) + C
where
•
K = Approach speed (1,600 mm/s, defined in ISO 13855)
•
T
M
= Stopping time of the machine or system
•
T
S
= Response time of the safety laser scanner
•
C = Supplement to prevent reaching over (850 mm)
