    Hi,
    I am having an issue where the SM74 is showing a loss of communication error. The press contines to run however there is a loss of control.

    Has anyone come across this issue?

    The user interface can not be used and the cp2000 loses connection with the press.

    Hi:
    Use the Schematic diagrams for Cp2000
    The first thing : 1) Check the Fuses: F1+f2+F3 15Amp, fast- blowing for Open in the
    Module GRM5Vdc Rectifier Module., they are input for 24Vac , and the Output is +34Vdc.
    2) Check the GRM24Vdc Module : Test the Fuses F1+f2= 16Amps- Fast-blowing for open in , the input is a) 26Vac, and output=37Vdc b) 37Vac and output = 52Vdc
    3) Check the GRM 120Vdc test fuse: f1+f2 for open use the Schematic Diagrams the output= + 127Vdc
    4) See if the input of machine: has a 10% of fluctuation voltage??? Very important, otherwise , there are a Great possibility the control board RSK120-2 Will be activate with a great fluctuation is coming.
    Let me know
    Blessing
