i have only worked on a few of the kone geared cars, one thing that i found interesting is that if you look at the LCE computer when you are scrolling thru the faults and sub codes, keep an eye on the led"s of the input and outputs of the LCE unit, they will show you the status of the led at the time of the fault, at least this is what i think i saw. maybe you can see 61:n signal still on, just a little input, i have had that fault before, and we swapped lu an ld sensors, and the problem just disappeared . damn elevators anyway
