    Okuma LNC8 Cadet Alarm 1125..! Anyone able to assist?

    My business partner and I recently purchased an older Okuma Cadet (LNC8) lathe, and are having some issues getting up and running. Lathe was functional before it was shipped, but when we powered it up for the first time (in our shop), there was a large arc, which turned out to be a chip that had fallen into the electrical cabinet. Long story short.. We replaced a burnt out power board (D11 Power Board), and the machine powers up and moves, etc.

    Trouble is we're getting "Alarm 1125 VAC communication" alarm, when the spindle rotation is commanded.
    The spindle begins to turn, but before it makes it a full revolution, it alarms out.

    When I looked in the Alarm manual, the Alarm WAS CIRCLED! Obviously, this machine has had this happen before, and (better yet) the issue was solved!

    Can anyone shed some light on this issue??
    We Need to get this thing making some chips! (*If anyone know what I MEAN!??)

    I had this alarm too, and believe me I had so many issues with it. I fixed it 3 or 4 times until my wife ordered a new alarm. This was almost 5 years ago. So, if I were you I would buy a new one and forget about it. Have a look https://www.1800doorbell.com/doorbells/business-chimes/ at these ones. No jokes, I have bought one more for our store. I mean, if yours still works than sure, use it until it breaks again, but I would change it, if I were you.

    Stop wasting your money on second hand things.

    Did you check main fuses and incoming power after the cabinet got damaged ?
    Any warning lights on the VAC itself ?
