Meaning
Long flash
= 0.5 s on / 1 s off
Short flash = 0.25 s on / 1 s off
OFF OFF Module not ready, no control voltage.
ON OFF Module ready, no error, at least one frequency inverter is communicating via the system bus
ON Short flashing Module ready, but
• One or more of the connected frequency inverters has fault status
Long flashing OFF Module ready and at least one other participant is connected to the system bus, but
• no frequency inverter connected to system bus (connection may be interrupted)
• one or more system bus clients has address error
• Software incompatible (module software and FI software do not match - update required)
Long flashing Short flashing
Flash interval
1 x - 1s pause
System bus is in status "Bus Warning"
• Communication on system bus disrupted
• No other clients available on system bus
• Module not inserted correctly or no connection to the system bus
• Frequency inverter has no supply voltage
Long flashing Short flashing
Flash interval
2 x - 1s pause
System bus is in status "Bus Off"
• the system bus 24V power supply was interrupted during operation
Long flashing Short flashing
Flash interval
3 x - 1s pause
System bus is in status "Bus Off"
• No system bus 24V power supply
Long flashing Short flashing
Flash interval
4 x - 1s pause
Module error
• see parameter P170
OFF Short flashing
Flash interval
1…7 - 1s pause
System error, internal program sequence interrupted
