    Does anyone know why the display council as well as all controls from press don't work?
    I've swaped almost all boards with no success.
    I thought for sure it was the 2 main boards ,ztk, svk3 but no success after replacement
    When I turn the main power on before the svk3 board has 3 little lights on it 1 of them used to turn on for 1 second then turn off. Now it dont light up when I turn on main power? The press also says EAM communication error. Any advice would be appreciated. Thank you.

    Hi sir:

    About your problem:

    1) in SKV3: Led Red H1: Light up if some Guard is open a) the same with : Led Red H2, b) Led Red H3= No function

    2) Now you have problem with the Power supply AC probably and DC.

    3) The following Vac with the DMM: in the Main Transformer T1, use the schematic diagrams.

    4) in The secondary winding of Main T of T1: a)22Vac b)17Vac c) 32Vac d)190Vac e) 37Vac f) 20Vac

    5) Board RPM: a) terminal X3 vs Grnd= 39Vdc

    6) Board SVK3 :a)terminal X6=24Vdc b) terminal X51= 24Vdc

    7) Board NTM2: + 8Vdc and - 8 Vdc

    8) Board NTM3: +5 vDC +12Vdc

    9) Board SVK41: +24vDC

    Use the Schematic Diagram +DMM, tolerance in Vac will be 10% up or down. Vdc will be 5% up or down.
