Been trying to t-shoot a Kone KCM 831. I can't seem to get it to run. I have 3 faults 0026, 0169 and 1801. I also have one drive fault 1657. I tried replacing the COP board, the old board has one button on it labeled s1 and the new board has a row of dip switches and two buttons s1 and s2. Performed a Lon download after waiting an hour for the display to change from CPU40 and start talking to me. Also tried ADON learn. Each time restarting power. No longer takes an hour to restart. Tried reseting faults at one point and the LCECPU40 board went into what I call christmas tree. (all the leds started twinkling and it eventually stopped on its own) I suspect I may have a bad drive, but this thing is not making much since. Thanks in advance for any help.

What type drive? Do you have drive ok light?

What’s the 0026 sub code
