KCM831 headache

I have a KCM831 giving me a 83 fault. I've tried to learn the hoist way but the CPU will not continue once 30 comes high. Any suggestions?

Does the car run normally on inspection?
Is 61U coming on before 30?
Are all your 77 switches in the correct state?
Are you getting any other faults?

Car runs normal on inspection from controller and car top. 77 u/n, 77s stays high, switches are good. 61 u/n comes up like it is supposed to. No other faults now.

77u/n function as they should. 77s stays high constantly.

Sorry, ya got me.

Do the 61 u,n and 30 turn on off at the floors? Is your 77 u and n magnet distance correct from your terminal floors? When your parameter for speed is set for your drive i belive that the distance of your 77 switches need to be correct or shaft learn cant be done.
