    We are currently running a sm74 di, The press will not boot without the imaging computer. We are using a platesetter so we really do not need the unit. There is a variant code to turn on and off the di portion. When we do it comes up with a dynamic fault red cannot run press. There is no location and nothing in service menu. We really want to disable this. If there is anybody that could help with this issue I am willing to pay a bounty. Thanks in advance.

    Hi sir:
    Hope you are well.

    If a malfunction occurs in the initilization phase, the detected Init-Error is displayed on the main control
    panel.

    Press operation is no longer possible.

    Can you send me a Pic what show in the imaging computer??

    In short, you must test first: 1) the power supply in the input of main transforme(primary winding)

    2) secondary winding of the main transformer, must be in 10% of tolerance up of down.

    3) if are o.k test the input and output of the GSM (bridege rectifier for to differents modules of machine) likr +48Vdc for G11+G12, use the schematic diagram.

    Let me know, if you have cptronic compact??

    Blessing
