    Our Heidelberg SM 52-4 is showing an error that says the syncronisation monitor is not acknowlidged by PU and the section 3 is unable to control from the monitor. There is also an error that there is a problem with connecting of main cylinder to the moving cylinder.
    We would be very grateful, if you could suggest us where the problem is.

    Sincerely,
    Tsegii

    Your machine is likely a perfector even though you dont mention that in your post. This is where your issue is. My question for you is, how old is the machine and does this error show up only in perfecting mode or both straight and perfecting mode?
