    Okuma RU1 board relays

    My LB15 won't unclamp the chuck. We have it narrowed down to the RU1 board. Can somebody please tell me which relays on the RU1 board need to be replaced when the board fails? Any help will be appreciated. Thanks.

    On my Cadet lathe, I changed CROKA and CRVAC relays. They are both Omron LY2N 24vdc relays.

    You must have an odd Cadet, all I saw had the RU1 board as well, and they are solder on.
    I can't seem to find my Cadet electrical prints right now, only the OLD LB15. I'll keep looking, they are labeled on the prints.
