Denford Software & Machines

Require advice/ help. Triac fanuc atc been working fine. I have moved it a few feet in garage and not used in a few months.
Now first phase of controller powers up then green light flashes and nothing happens when I press again also emergency msg flashes but no details generated.
Machine is against a wall so need to skate out to access electrical cabinet. Could do with some pointers to start with. Thanks in advance
