5.7
Safeguarding Mobile Machines
Please comply with the safety notes in Chapter 3.
5.7.1
The Purpose of Safeguarding
is for protection:
•
to protect people when entering variable danger zones
•
to protect objects located in the vehicle path
•
to protect the automatic guided vehicle and its load
5.7.2
Installing adjacent laser scanners
The SIMATIC FS600 Laser Scanner has been developed in a way that prevents several
laser scanners from interfering with one other as much as possible.
WARNING
An increase in the response time can, however, be caused by the installation of several
adjacent laser scanners. If none of the constructive measures (section 5.2.1) described
in the following sections or the specific adjustment (section 5.2.2) are implemented,
then the SIMATIC FS600 Laser Scanner response time set and shown in the
configuration and diagnosis software (SIMATIC FS600 Parameterization
Software LS4soft) is extended by 40 ms. This extension in the response time MUST
be taken into account when calculating the safety distance!
5.7.3
Mounting Position
For the purpose of safeguarding the path of a vehicle, the SIMATIC FS600 Laser
Scanner is mounted on the front of a vehicle (in each direction of travel), preferably in
the center.
The scanner, and hence the beam axis, must be aligned horizontally in order to achieve
a consistent scanning height.
Please comply with the safety notes in Chapter 3.7.
5.7.4
Mounting Height
As a rule, the scanner should be mounted as low as possible in order to prevent people
from crawling beneath the detection zone. This specification is limited due to such
factors as uneven floors or the deflection of the springs in the AGV.
The maximum mounting height must be selected so that an object (cylinder with a
diameter of 200 mm in the prone position) is reliably detected (see DIN EN 1525). The
detection must be tested at the position of maximum depth within the detection zone. For
AGV applications, sufficient resolution of detection is achieved when an object (upright
cylinder) with a diameter of 70 mm can be detected throughout the detection zone.
