8.3 Fault indicators at system level
Faults that occur on the profiling system are divided into two basic categories: warnings
and errors:
• In the event of a warning, the system remains operational. However, the cause of the
fault must be eliminated as quickly as possible.
Warnings indicate things like minor contamination on a 2D LiDAR sensor.
• In the event of an error, the system is still operational in principle. However, the system
can no longer be relied on to function correctly.
