SICK S3000 PROFINET IO User Manual

NOTE
•
T
he device must only be used to protect vehicles that are powered by an electric
motor.
•
Because the safety laser scanner itself is moving in a mobile application, a resolu‐
tion of 70 mm is sufficient for detecting people.
•
In the following calculations, only the vehicle speed is taken into account and not
the speed of a walking person. This is based on the assumption that the person
recognizes the danger and stands still.
•
If the application is to protect vehicles from collisions, then it may be necessary to
use different assumptions.
For a horizontally mounted mobile application, you determine the following:
•
Pr
otective field length
•
Protective field width
•
Height of the scan plane
•
Restart behavior
•
Measures to prevent unsecured areas
4.3.7.1 Protective field length
Overview
Y
ou must configure the protective field so that a minimum distance to the vehicle is
upheld. This minimum distance ensures that a vehicle monitored by the safety laser
scanner stops before a person or an object is reached.
NOTE
If y
ou define several monitoring cases with different protective fields, and in particular if
you switch between monitoring cases depending on the speed, you must calculate the
protective field lengths for all protective fields used.
Protective field length S

C
alculate the protective field length S
L
using the following formula:
•
S

B
where
•
S
A
= Stopping distance
•
Z
G
= General supplement = 100 mm
•
Z
R
= Supplement for a possible reflection-related measurement error of the safety
laser scanner
•
Z
F
= Supplement for a possible lack of ground clearance of the vehicle
•
Z
B
= Supplement for the decreasing braking force of the vehicle as specified in the
relevant vehicle documentation
Stopping distance S
A
T
he stopping distance comprises the vehicle’s braking distance and the distance cov‐
ered during the safety laser scanner’s response time and the vehicle control’s response
time.
