How to calculate the minimum distance S (see EN ISO 13855):
 First, calculate S using the following formula:
S
=(K × (T
M
+
T
S
)
) + Z
G
+
Z
R
+
C
Where …
K = Approach speed (1600 mm/s, defined in EN ISO 13855)
T
M
=
Stopping/run-down time of the machine or system
T
S
= Response time of the S3000 and the downstream controller
Z
G
= General safety supplement = 100 mm
Z
R
= Supplement for measurement error related to reflection
C = Supplement for prevention of reaching over
Response time T
S
of the S3000
The response time T
S
of the S3000 depends on …
 the resolution used.
 the multiple sampling set.
 the transmission speed to external OSSDs over EFI.
See section 12.2 “OSSD response times” on page 144.
Supplement Z
R
for measurement errors caused by reflection
Avoid mounting retroreflectors at a distance of less than one meter from the boundary
of the protective field!
With retroreflectors positioned at a distance of less than 1 m from the boundary of the
protective field a supplement, Z
R
, of 200 mm must be added to the protective field.
