    Lithrone GL-540
    Hello, I have a problem with machine lithrone gl-540 H-UV. Sometimes it writes out following errors and it stops working and then it starts work again after a while. There is error lightning on the PLC.
    Thank you .

    Hi sir:

    Hope you are well.

    Attached is there a schematic how is coming any PLC from any mark: siemens, allen bradlley, senator, etc

    Please test 1) the power supply according with the schematic for PLC, can be 2 options: a) Vac or b) Vdc and see if there are in the tolerance 0.7% up or down, example if you are measuring +24Vdc, and measure 24.7 is out you must fix it o replace .

    2) as you will see the power supply +clock is feeding to CPU, if this p. supply +clock is NOT o.k the CPU, will work erratic.

    3)Look for all Edge connector in all electronic boards,for dirty, dust, or corrosion and back end.

    4) look for dry+colder joint solder in all electronic board from PLC.

    5) Test the battery of PLC, if there o.k remember if you have to replace , do it with the same type.

    6) if the problem persist, the Software of PLC, can be corrupt and must install again with some update.

    Blessing
