How to calculate the minimum distance S (see EN ISO 13855):
First, calculate S using the following formula:
S
= (K × (T
M
+
T
S
)
) + C
Where …
K = Approach speed (1600 mm/s, defined in EN ISO 13855)
T
M
= Stopping/run-down time of the machine or system
T
S
= Response time of the S300
C = Supplement against reaching through (850 mm)
Response time T
S
of the S300
The total response time of the S300 must not be more than 80 ms for access pro-
tection!
If a critical response time is exceeded (for an object diameter of 150 mm and a speed of
1.6 m/s that is 90 ms) a person may no longer be detected under certain circumstances.
In specific cases agreed with the responsible authorities higher response times may be
allowed (for example by increasing the detection time available by positioning the safety
laser scanner at an angle). In this case ensure that the areas the safety laser scanner
cannot see are protected by additional measures.
The response time T
S
of the S300 depends on …
the basic response time of the S300,
the multiple sampling set,
the transmission speed to external OSSDs via EFI.
See section 12.2 “OSSD response times” on page 117.
