I bought 3 Multiplus 2 5000 230V. I have updated all 3 with the latest firmware and connected these to a Cerbo GX. Via Config, I copied the configration of one to all 3, connected them with Ethernet cables to each other via VE Bus. These weren't connected to 230V, just to a 48V powersupply. Suddenly, two of them started flashing all LEDs and don't turn on. I cannot connect to these anymore. The 3rd one works well. How do I get the other two running again?
Additional info: VRM portal shows VE.Bus error 3
