General Error Messages
The CAN bus is designed for redundancy and carries out error processing in the
background.
“One” CAN bus has failed.
Reaction:
This error can be detected only by constantly observing the display unit.
If one CAN bus fails (for example if the plug comes loose) the display information is
frozen briefly (for appr. 2 seconds) while the data is transferred to the second CAN bus.
No special message is output onto the display unit.
Once the data has changed over to the second bus data transfer will continue
undisturbed. User functions are not restricted as long as only one fault is present.
No usable data on the CAN bus.
