Dear All,
I have an alarm "Inoperative" on the HMI of the Elektronicon controller on ATLAS Copco air compressor ZT110, which prevents the starting of the compressor. Communication cable between HMI display unit and controller has been checked and it was OK. I appreciate for any help about this issue.

 

Hello sir
I have the same problem if you were able to solve it, you can help me.
Kind regards,
