b
Make the undercut
1
sufficiently deep that it completely covers the area not pro‐
tected by the safety laser scanner (
) and so that it is not possible to
stand behind the unsecured areas.
b
Prevent crawling beneath the undercut by making the height of the undercut
2
sufficiently small so that no one can crawl under it.
Mounting in the vehicle paneling
Figure 28: Installing the device in the vehicle paneling
b
Install the safety laser scanner in the vehicle paneling in such a way that the unse‐
cured areas are ≤ 70 mm in size and the safety laser scanner protrudes no more
than 109 mm beyond the front edge of the vehicle. The vehicle can then be accel‐
erated to a speed of 0.3 m/s within one second.
Complementary information
By observing all the necessary safety measures, it may be possible to avoid using a
restart interlock and thereby potentially increase the availability of the system.

Near range
The near range is a 5 cm wide area in front of the optics cover. Use a bracket or under‐
cut to prevent persons from entering the near range or provide additional protection
using a close-range scanner with a detection range of 5 cm. The vehicle can then be
accelerated at any rate.
4.3.3
Timing for monitoring case switching
Overview
When switching between monitoring cases, it is possible that a person may already be
in the newly activated protective field when switching takes place. Only by switching in
the correct time frame (i.e., before the hazard occurs at this point for the person) is pro‐
tection provided.
You must advance the switching time in the following situations:
•
You have entered an input delay for the switching method.
•
You are using external inputs (e.g., the inputs of another S3000).
•
You are controlling external OSSDs via EFI (e.g., the OSSDs on another S3000)
instead of the internal OSSDs.
The following diagram illustrates the relationships:
