Mounting
The minimum distance S depends on:
 approach speed of the body or parts of the body
 stopping/run-down time of the machine or system
(The stopping/run-down time is shown in the machine documentation or must be
determined by taking a measurement.)
 response time of the S300
 supplements for general measurement errors and any measurement errors related to
reflection
 supplement for prevention of reaching over
 height of the scan plane
 possibly the time for switching between the monitoring cases
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 S300 and the downstream controller
Z
G
= General safety supplement of the S300 = 100 mm
Z
R
= Supplement for measurement error related to reflection
C = Supplement for prevention of reaching over
Response time T
S
of the S300
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.
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.
