Toshiba Tosvert-130 transistor invertor

As the title says, I was called by a company that fix aeroplane parts, they have a machine that is used for testing generators, it's stopped working and I was asked to have a look. I've told them it's way out of my depth and I pretty much don't have a clue, but said I would stop by and get a look at the machine and see if I could find any information out. Had a look and seen that the invertor display panel had ST-CC is open, had a look at the manual and it seems it needs to be closed for it to run, has anyone worked on these before, or know someone that could fix it, I'm in Edinburgh, cheers!

A quick google says that ST is a terminal on the drive and needs to be connected to CC, which is a common for terminals, for the drive to be released to run.

There will be something connected across these terminals, a relay contact from some part of the process or within the panel, and thats what I would be looking at. Likely that the inverter itself is fine.
