    Hey guys, how do

    Old school printer battling the world of microprocessors! I can't tell you how galling it
    Is to have a tiny chip tell you it will not allow the press to run because the delivery tray
    Is on the floor, or some other procedural technicality even though there is nothing physically preventing the press from running *dude! i mean it's like whats the worst
    Can happen right? So i get around to the delivery end & theres a whole pile of sheets on the floor! Ive had worse!... trust me!

    O,k seriously can you young guns introduce me to the minefield of "init tests" "dyn" tests, haks & reks etc etc? How exactly does a guy perform/execute such tests.
    You know Once apon a time it was all about ink/water balance & skill...

    Oh the pain! The pain...

    Cheers! and go easy on me, first time.

    I feel your pain, Kart...but keep in mind, you don't perform these tests, the press is constantly monitoring itself. All you do is go into the Initiation test (diagnostics upon turning the machine on)and Dynamics test (diagnostics while machine is running) screens to determine where a problem may be. Stress MAY. No forum will be able to run you through even the basics of understanding what goes on in that cabinet, but suggest you get your schematics and whatever documentation you may have gotten with the machine, look through and familiarize yourself with the acronyms for each board and what functions they are responsible for. That's a start, anyway.

    I can feel your pain Kart, My father, an old school master printer suffered the same when introduced to the newer machines.

    Hi kart,
    Let me add my comment here,
    Microprocessors are there to assist you throughout the entire process and most importantly ensure your security. What you experience is the effort of lots of heidelberg engineers spent hundreds of hours writing programs to make your machine run fine, to give you better output and ensure your safety. So please don't yell at microprocessors. :)

    I will explain very briefly what are those tests. (as junker said, no forum can explain what's going on inside that cabinet, but I'll try to be as simple as possible)

    As junker said, you don't need to perform any of these tests. As soon as you turn the machine on, it will self test most of the functional modules to ensure the correct function. even the small light bulbs inside the buttons. That's all for the safety of yourself and the machine itself. That you called the initialization test or in short, "INIT TEST"

    Suppose the machine develops a problem when running or getting ready to run. Then that will be indicated under the category of the Dynamics test or "DYN TEST"

    For example, let's say it can't recognize one of your water pan roller motor ( eg. the wire may be disconnected) as soon as the heidelberg logo disappeared in the display, it will report the error under init test section. (But unfortunately with a error code in hexadecimal, so without the explanation chart, you can't understand it) then the service engineer knows the fault and can easily be corrected.

    Have you heard the main motor is "humming" or "buzzing" after you press the run button for the first time, during the pre- run alarm? There it's performing the "main motor brake test". The control system try to rotate the motor while applying the brake. The motor should not move at all. If the motor moves, them you don't have brakes. So that it won't allow you to put the machine into run. and it will indicate under the dyn test section.

    Think for a second, what if you got an emergency and need to stop as quickly as possible when the machine runs at 12000 with no brakes? :p That's the advantage of microprocessors.

    REK is the main computer card and HAK is the auxiliary drive card. Those 3 letter names are acronyms in German. you can see them all at the last pages of the wiring diagram book.

    HAK and REK is the names of 2 cards of the CP-TRONIC modular system. Since the SM52 has the CP-TRONIC compact system, you don't have such cards. So don't worry about it.

    I know, it's sometimes pain in the *** to troubleshoot these systems. But it has more advantages than the electrical system you had in the old GTOs and KORDs. That's why these systems exists.

    Hope this helps.
    Cheers.

    Sure brother,

    Kartal.kaba55@gmail.com

    What is the print culture like in pakistan? I here you guys print 15k p/h 24/7
    Is it just a myth?

    Here in the land of "Oz" the print market is pretty insignificant compared to asia/europe. We can't even find qualified techs sometimes..

    Cheers...

    There are some big printers who run 24/7 with speeds as fast as 16k but not many.
    Most print houses here have machines from 70s and 80s and they run from 5-8 Ks.
    Most of them conventional dampening, We still have ROTAPRINTS, Solna, Rolands and Millers here but things are changing now and many printers are now ordering newer and bigger presses.

    Regards

    Hi.
    Situation is more or less the same here in sri lanka as aqazi said. But we have mostly heidelbergs. And secondly Japanese machines.

    Our market is also flooded with Heidelberg and Komori but now KBA is the new trend here.

    Only one of my clients has a KBA Rapida 72K. Imported by himself. Other than that, no clues about KBAs here.
