Complementary information
If onl
y part of the opening protrudes into the vehicle travel path from the side, this
design of the width may result in the opening not being detected. The vehicle could
drive into the opening and crash to the side. To prevent this, a lateral supplement
corresponding to the configured object resolution (gap size) may need to be added to
the contour detection field.
4.4 Integrating the equipment into the electrical control
Requirements for use
•
T
he control of the machine can be electrically influenced.
•
The connected controller and all devices responsible for safety comply with the
required performance level and the required category (for example according to
ISO13849-1).
•
Power is supplied to all electrically connected devices in accordance with SELV/
PELV (IEC60204-1).
•
All devices connected to a local input or output are in the same SELV/PELV circuit
as the product.
•
All electrically connected devices use the same earthing method.
•
All earthing points are connected with the same ground potential.

4.4.1 Electromagnetic compatibility
Overview
S
afety components switch all safety outputs to the OFF state in the event of errors in
order to rule out potentially dangerous situations. For example, faulty data transmission
must lead to a shutdown for safety-related devices, even if it can be tolerated for
non-safety-related devices.
