    I have a PM52-2 and it's on a lock down at the moment. It was doing a changeover from straight to perfect print and it stopped and locked itself. Errors P2E,P21 & PO2 are flashing on the display screen. Machine cannot move or inch. Need expert advice.

    Hi sir
    Good day hope you are well.
    Some problem in the perfector system occur, by bad operation:
    Try to follow this step: you have undefined position perfector: 1) do this:Carry out changeover procedure back to front-side printing. Press is operative again in front-side printing. 2) Carry out changeover procedure or sheet length change once more.
    Let me know any question or doubt

    Please test the Limit Switchs :
    p-b229 + sensor RL8.1 +L.switch p-b231 for dirty, or loose wires, or lack of voltages, or dissadjustment.

    Hi bert
    Your press has locked up during a change over be it the operator opening a guard or one of the steps in the change over hasn't made position. It's not easy to get the machine back to straight printing over a forum its generally done by an experienced heidelberg tech.
    You need to clear the errors then maybe manually get it back to straight mode then do a learning run then see why it locked up in the first place. Maybe call heidelberg nz and see if they can help.

    Heidelberg NZ is not responding. This error happened some time ago and they had to send in 3 engineers to solve the 4th engineer they sent did the job.

    I have heard of an ex heidelberg tech from nz working in Fiji not sure if he is still there or up to the job i can make some enquiries if you want.
    But i do know this isn't a simple job you can fix over a forum

    Hi sir:
    Did you do the this steps:Try to follow this step: you have undefined position perfector: 1) do this:Carry out changeover procedure back to front-side printing. Press is operative again in front-side printing. 2) Carry out changeover procedure or sheet length change once more.? 2) and you did and NOT work? 3)
    Did you test the Limit Switchs :
    p-b229 + sensor RL8.1 +L.switch p-b231 for dirty, or loose wires, or lack of voltages, or dissadjustment.?
    You must use the "Common sense" Remember you, the Most Valuable Tool for ANY troubleshooting is your 5 Senses.
    Let me know, because Otherwise IF you do NOT have the Skill for Repair or fix it , Will be agree with the Colleague Contractor, to call the Service Heidelberg.
    Let Me Know.

    There are many, many reasons that your machine can lock up during a changeover. As already noted above, this is best to have an experienced Heidelberg tech come take a look at the machine. This is nearly impossible to fix in an online forum.

    Hi sir:

    Please look for this:
    Select emergency stop or Control panel pushbutton on printing unit

    We have check everything in the machine , According to mechanic the segment gear is now stopped where
    It’s supposed to , but the machine perfector encoder is 89.5 and not changed, on the screen it’s showing 79.6 and operator side too 79.6 , but perfector encoder is 89.5

    This is a great diffetence between the encoders .
    Normally must have the 0.03 degree of tolerance .
    Plese change the ids and let me know
