    Welcome ........1.2 is back up power supply or main fuse .. we have a puma fault finding guide on here .. have a read of that ... your other issue will be most likely a main earth/poor ground (Ive started your own thread too .. best to do this rather than tag onto someone elses )
    Please don't PM me for plant advice.. thanks .. Post in the forum where I will gladly help, as will many of our contributors.. as the info and responses will help everyone else, which is why we exist

    Hello,

    a friend of mine has aproblem on this machine, fitted with Puma controller, error is FC 1.2, no manual available. Machine won't start, i have allready replaced solid state relay VN16B, which was shorted from 12V to pin 31. Still no joy. I can't access scans on this site, God knows why.

    regards

    Sorry

    Sorry, have just started new thread about this, late to see your answer.
    The fuse panel is badly melted, next week will start painfull reconstruction with no manual.

    Thank you.
