    At first, the water ductor of the first section failed.
    A little later, sections two and three stopped showing the indication of functions, when you press the buttons there is a sound signal but there is no turning on / off of the water and paint supply ducts. The pneumatic function of lowering the shafts onto the plate is working.
    I assume that the problem is in the frequency converter of the water ductor of the first section and the failure of the control boards of an unclear volume.
    ASK FOR HELP!

    Hi sir;

    You must look, if there are loose wires, or deteriored cables , that are NOT more isolated.

    2) see if other section of machine, have wires in the same way, and look, if the Fans Are working good, or they are faulty, otherwise will be a reason for reheating, and smell to burn.

    3) see if there are some Rat, or similar, that they cooke for the Voltage, or broken wires!

    So.
    Two boards, a mentor, a motor-reducer of the water supply shaft were checked.
    There was nothing difficult to repair except for the search and delivery of analogues of Japanese microcircuits.
    The water control board is in good order, the mentor is burnt on the side of the supply voltage 200V AC, the motor-reducer is in good order.
    The signal control board required the replacement of the comparator and thyristor assembly.
    Now the repair service is bored, we are sharpening hammers for the next repair)))
