Meaning
Long flashing
= 0.5 s on / 1 s off
Short flashing = 0.25 s on / 1 s off
OFF OFF Technology unit not ready, no control voltage
ON OFF Technology unit ready, no error, at least one frequency inverter is communicating via the system bus
ON Short flashing Technology unit ready, however
• One or more of the connected frequency inverters is in fault status
Long flashing OFF Technology unit ready and at least one further participant is connected to the system bus, but
• No frequency inverter on the system bus (or connection interrupted)
• Address error for one or more system bus participants
Long flashing Short flashing
Flash interval
1 x - 1s pause
System bus is in status "Bus Warning"
• Communication on system bus interrupted or
• No other participant present on the system bus
Long flashing Short flashing
Flash interval
2 x - 1s pause
• System bus is in status "Bus off" or
• The system bus 24V power supply was interrupted during operation
Long flashing Short flashing
Flash interval
3 x - 1s pause
• No system bus 24V power supply (system bus is in status "Bus off")
Long flashing Short flashing
Flash interval
4 x - 1s pause
Module error
• EEPROM error
Long flashing Short flashing
Flash interval
5 x - 1s pause
Module error
• AOUT error (analog output)
• DIP switch configuration error
OFF Short flashing
Flash interval
1…7 - 1s pause
System error, internal program sequence interrupted
• EMC interference (observe wiring guidelines!)
• Module faulty
