when i switch on my 3 phase system, the Multiplus-II needs several minutes to start (3 x Multiplus-II 48/5000 and a Cerbos GX) Most of the time i will get several:
VE.Bus Error: VE.Bus Error 10: System time synchronisation problem occurred
today i got a new one and the Multiplus-II stopped:
VE.Bus Error: VE.Bus Error 8: Ground relay test failed</pre>
There is no load connected to the Multiplus and they are all connected to earth via the input connector as well as by the chassis ground screw. It is an ESS 3 Phase system with a Fronius Symo 8.2-3-M.
One of the Multiplus has been installed end of November, the additional 2 ones in January.
