    Hello everyone,

    I have issue with Komori Lithrone 40 working panel, more precisely unit select keys, after switching on the machine they start blinking and after all of them blinked it switches off. It doesn't show me any error code on my PQC and if anybody have any information or can help me please write.
    It's been 3 months since it happened.

    So when I turn on the press, all lights on working panel board switch on and then they switch off, press is working but I can't control the units and I can't load my file for printing form, only for example if I use button stop and stop the light on one of the units I am able to print on only one where I stopped it, if I try to press any other or to switch on more units or to press this buttons it's not allowing me, zero response. I tried with changing whole panel but it gives me still same outcome.

    Dear Komori,

    I do not familiar with the machine, general recommendations:

    It looks as a fatal error which does not allow to start controlling, a control indicates it by flashing the buttons and turns itself off.

    Continue to do something and the God will assist you:
    At least you know that the flashing panel is ok.

    It is seen another panel from left which may also participate in the controlling, power supplies, control unit itself, SENSORS,.. even cabling from the control to executive mechanisms or from sensors.

    Do not concentrate on the buttons, the problem is located in another component.
    Prehistory of the fault and visual inspection?

    Off the subject please:
    What type of the monitor is used in the machine, what is its interface if known?

    Regards,

    Dear Komori,

    I do not know what is PQC4, sorry. All my current ideas were listed in my previous message, start to execute them until a more exact recommendation from someone.
