Omag cnc mill error code, num control

Hi All
I want to know if any one has any experience with Omag machines or Num controls. I am incharge of Omags largest and only one cnc mill (mill5) at work. It has been running fine til yesterday when it got a error code , (power remote control buttons disconnected, check voltage). Been try to correpond with the manufacturer and alot is lost in translation. The mill will power up but wont run while error code is present. I have gone thru most of the systems and also the pendant and cant find anything wrong. But i dont know what systems it is refering to either.
Thanks for your help in advanced.

IN NUM CONTROL ON YOUR CDS YOU SHOULD HAVE A NUM CONTROL FAULT LIST YOUR FAULT LISTS AS CHECK REMOTE CONTROL SWITCHES VOLTAGE AS A SOLUTION.I DON'T KNOW THE VOLTAGE BUT GOOD LUCK WITH THAT.MY CNC IS DOWN TODAY AS WELL WITH A TOOL RACK PISTON UNRELEASED ERROR.
