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.

Re: Okuma RU1 board 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.

Same problem on our cadet. Both sides of the solenoid is magnitized, So we found a used board. But I will see if replacing those relays fix our bad board. Thanks for the post
Re: Okuma RU1 board relays
Did you have any luck replacing the relays on your board.
Also any guidance on finding the RU1 board, have a 199 Okuma Crown L1060. giving me Alarm 1725-A CHUCK ls-sol mismatch
That alarm means your prox switches are opposite to what your solenoids are trying to do. Switch them and your alarm should go away. You should see actuator and jaws move if you reset and try other direction before alarm occurs. That would mean all functional but prox reversed.
Experience is what you get just after you needed it.
