    Question Fanuc OT Colchester Lathe 911 ram parity high Alarm

    Hi guys,

    Display screen came up with BATT on bottom and i couldn't home or rapid jog or anything except handle jog. I changed the D-cell batteries in the back however didn't realise the machine should have been ON before removing the old ones. shyt...

    Now on startup i get a 911 ram parity high Alarm. cannot get any buttons to work.

    From what I've found i think i need to reset during control startup and re-enter all the parameters. I've never had to do this sorta stuff before. I have all the manuals for it but is there a list of parameters that would be model specific to my machine? Its a Colchester 2000l with Fanuc OT control.

    Any help would be appriciated, cheers.

    You have to clear the memory and reload the parameters and 'diagnostics'; these are specific to your machine, but getting them from an identical model should get you up running again.

    Thanks memoryman. Any other ideas on how to get the parameters and diagnostics? Any online sources or Fanuc themselves? Cheers

    Ask for it on this forum; contact former distributors for customers with the same machine.
