What to do if Weishaupt Control Unit shows fault code F9?
If your Weishaupt Control Unit displays fault code F9, it indicates a faulty connection to the Fieldbus. This can happen if there's no query within one minute (Modbus) or the cyclic data flow was interrupted (Profibus). To resolve this, check the Bus connection.
Why does my Weishaupt EM3/2 Control Unit show fault code 18h?
Fault code 18h on your Weishaupt Control Unit indicates several potential issues: * A1h Invalid Bus address: Check the Bus address. * A5h Configuration at output B4 incorrect: Verify the configuration at output B4. * A9h No Bus connection: Check the Bus connection. * EEh Communication to W-FM 25 failed: No solution mentioned. * EFh Extension module to W-FM 25 not compatible: Check the version.
