Status LEDs

The following table gives the descriptions for all LED states.

System LED Description
Green System is error free
Red System error
Orange System is not ready; boot procedure is running
Orange flashing System is not ready; download is active

 

Channel LED Description Description
(Connector 1, CAN bus)
Green Channel is ready CAN bus activated, CAN data can be received
All orange Boot procedure is running  
All orange flashing Download is active  
Orange Connection is newly assigned; transducer identification is running CAN data received but bus is occasionally disturbed; buffer overflow; individual data loss
Green flashing, then green TEDS data is being read  
Orange flashing, then green Manual configuration; ignore TEDS  
Red No sensor connected; channel error (incorrect parameterization, connection error, invalid TEDS data) CAN bus error; CAN interface in Bus OFF state; CAN data cannot be received or processed
