    Hi sir:
    Please Reset the CPU.
    Attached is there the schematic how to do it.
    Search in Google your particular CPU that you have in the MOBO(motherboard) example 80836,
    look for Schematic Pins: a) RST =reset ++B) GND= ground , take a piece of wire make a bridge betwen 2 pins like
    appear in the schematic attached.
    Blessing.

    hi Chock, yes, the problem is cpu reset in MOBO, we check already our cpu reset wire still connect to the ground.
    first we start the power. our cpu reset pointing like attachment picture with 3 (three) lamp on.
    there should be only 1 (one) lamp on ?
    our sm52 machine is 4 units, we try to change the cpu with the other sm 52,
    and its ok with the other and the lamp only 1 (one) on ?

    So, I tried to exchange the boards one by one onto the other machine and discovered that the broken part is the ESK board. Thank you for the help!

    ok sir.
    Great!

    The input/output control board ESK receives and
    processes the signals from the encoder IDS.
    The ESK provides the electronic control system with
    parallel and serial interfaces.

    Blessing.
