11.3 Fault indication on the display
Overview
If t
here is a fault, the display shows a warning symbol, a type of fault and a fault code
on a red flashing background.

T
he two-character fault type will help you during troubleshooting.
•
The eight-character fault code in the bottom line helps SICK support during the
detailed fault analysis.
•
Pressing the button briefly shows you more information about the fault for trou‐
bleshooting.
•
You will find detailed information in Safety Designer’s message history about the
individual faults and information about events not shown by the display.
