I have two KONE escalators with the exact symptoms. Both read a 90(ready mode)on the processor board, they will both run in the UP direction for about 2 full revolutions, but only if you hold the key in the UP. Neither unit will run in the down, neither unit will run on automatic. No faults latched, always reads 90. I am getting K1/K2, but I do not get K14 when trying to run down.
