Hi dknnaird,

I work in the field (i normally browse on here) and i experience this multiple times per week as my area uses a mix of Blue and Red Corner sites.

This fault appears after the mains has been removed and then replaced. For some reason the two processors refuse to synchronize and communicate with each other resulting in this.

I found it interesting that a software update was offered as up to now my customer is yet to receive any advice as to a fix.

What i did notice from the faults you posted following the updated R11 software is that it just seems to give more detail/more fault flags to the same ‘ballpark’ flag.

I know this doesn’t really offer much help but it would be interesting if anyone else has been given a genuine fix to this.

Take care.
