    make sure your press model number is correct, it is CD102 or CD74.
    please post your press initial test and dny test images with your camera, that way we can analyze the cause.
    thanks!

    All unit Dampening and Suction motor work fine.
    when I press pile button, LTK500 led goes off for a second and sound come from motor but not rotate.

    did you check feeder main pile brake coil and delivery main pile brake coil resistance?

    if you have auxiliary pile at feeder, you can swap STK1 and STK2 board, see what happens.
    Strong recommended, resitting all HAK2 boards, and swap first two HAK2 boards from the last two HAK2 boards.
