    I had the plate clamp piston fire when the press was running, tore up the lever and bushing and bracket that goes to unit 1 plate clamp. We fixed it all and 1 week later it happened again. Heidelberg says it has happened on other machines and that it was fixed by replacing the ZTK circuit board ($3K) He told me one guy had it tear up 3 times. Seems to me there's a problem here but I thought about it over the weekend and decided to put a switch on that circuit and I got it inside the op side cover, I just flip it on when I'm redy to load a plate and leave it off the rest of the time, that way it can't fire and tear up the press again. Anyone else have this happen?

    Banjoman, I guess if you can install a switch, I would also install a small light or lighted switch to see if the press is actually sending a signal to the ram or if it is some other issue. I haven't heard of this before, except if the pneumatic saftey switch is not working and the press is low on air pressure. The ram you are talking about is held open by air pressure. I do have that board available at a much better price if you end up needing it. I also have numerous new and used parts avail for the press. Stan IPS,llc. 720-285-9485

    Recently one of the ICs on our ZTK boards ref ZTK00.781.3640/01BAU blew up. We had it replaced but the board could not come on. The PC Board reference is given as A1.144.9114/08ZTK29300896. We have been in touch with Heidelberg price offered for a replacement is very high. I will be glad if anyone can offer us a replacent or even fix the one we have. Best regards, Raphael +263772282696.

    I put a switch on the wire that fires that plate clamp and ran it over to the operator side under the cover and had it like that for a couple years but last year I broke down and had Heidelberg install a new ZTK board, it was about almost $5,000 for the service call and the board, ridiculous! Ive seen some used boards around and there are some places that repair them but Heidelberg can trouble shoot it better than anyone else.
