Example
•
Monitoring case 1 (standstill)
–10 … +10 cm/s
•
Monitoring case 2 (forward movement 1)
11 … 50 cm/s
•
Monitoring case 3 (forward movement 2)
51 … 100 cm/s
•
Monitoring case 4 (forward movement 3)
101 … 200 cm/s
NOTE
When configuring the monitoring cases in the CDS, you must cover all possible or
allowed speeds of the vehicle. An undefined speed will result in the safety outputs
being switched to the OFF state or the device signaling
Protective field interrupted
. You can
use this function, for example, for safe maximum speed monitoring on vehicles.
Disabling tolerance ranges, monitoring speed thresholds
Modern applications for autonomous vehicles require additional configuration features
for driving around tight bends.
The S3000 offers the following additional functions:
•
The tolerance ranges (
see "Tolerances allowed on the dynamic inputs", page 91
can be disabled if the vehicle is to drive around tight bends and as a result the
standard tolerances will result in unintentional shutdowns.
b
On the
Cases
tab in the CDS, select the
Monitor speed thresholds
function.
If a defined threshold is exceeded, the safety laser scanner shuts down. Speed differ‐
ences larger than 45% are tolerated for 60 seconds. Only if the threshold is exceeded
does a shutdown occur.
The information on the minimum and maximum speed is determined for the threshold
and in this case is not used for the speed-dependent monitoring case activation.
NOTE
•
The redundant speed monitoring by the safety laser scanner is deactivated for
max. 60 seconds. You must ensure that the safety requirements for the applica‐
tion are met.
•
For safety reasons, the 60 seconds criterion must never be exceeded. The safety
laser scanner then switches its OSSDs to the OFF state, i.e., tight bends are not
allowed to last more than 60 seconds.

Speed routing via EFI
Overview
If several safety laser scanners are connected to a Flexi Soft safety controller, then a
speed routing can be configured. This enables the speed information determined using
the incremental encoders on an S3000 Professional or Expert to be distributed to all
safety laser scanners.
NOTE
Speed routing is not available in the compatibility mode.
