URGENT HELP NEEDED! 1995 Heidelberg 102 CPC 1.04 malfunction

I was running the press when the CPC console display ("ZID") went out.
We called Heidelberg to get a new one they said it was $5000+ so we decided to save some money and bought one out of Florida.
When we put the new one in the press the display showed the lateral and horz. positions at zero, the ink keys closed.
What the display shows and what the press is doing (ink keys, lat, horz pos. and inkfountain roller speed) don't match.
The transformer is fine,there are no burn't fuses, one odd thing, the power to the NTE boards match what they should be except when you plug them in you get a diff reading.
The GSM rectifier is fine.
There is correct power to the potentiometers.
Are guess was the TSK board was bad, replaced,no luck.
We called Heidelberg tech, they we're surprisingly unhelpful.

Please post quick or email me @ gregmartone@hotmail.com
--------exheidmech please email me (or any other pros)----------

 

with your problem, as you use a replacment but no the Heidelberg's, Heidelberg is normal surprisingly unhelpful.

Will send you a mail.

 

Is your replacement ZID same version as original? Double check to be sure. Also possible that what you got as replacement is defective. Consider getting another from those people you got it as a warranty exchange.

The new one has a grey screen(LCD) the old one had orange text. I switched the CPC zid console with the CP zid console, just to make sure the new one is not an issue,no difference.

 

Was the troubleshooting done by a knowledgeable electrician? You may want to take another look at the power supplies, particularely the +5 volt. It is normal that when plugged in, a power supply reading changes slightly with the load.
However, these power supplies are regulated and should not vary by more than +- 2%. You may have another load issue in the rack if the reading drops more. The AC voltage to the boards, before it is converted to DC, might be too low.

The guy doing the electrical testing is a coworker. He's real knowledgeable on computers and electrical.
The voltages are correct until you plug into the NTE power supply, the voltage increases for some reason.
There are five identical NTE power supplies. We tried to swap them, and still got the same result.
I went to your website I see you are mainly Man Roland do you work on and have parts for Heidelbergs?

 

I started out working on manroland equipment 25 years ago. Many of my customers had Heidelbergs in the plant as well, so I started servicing them. Then Komori, Mitsubishi, Harris and many others. We are manroland specialists but carry a diverse inventory of boards and components including for Heidelberg. However, we only provide on-site troubleshooting locally in the midwest. Contact me via email, and I can provide you with more info on how to proceed from here.

Take care

 

It sounds to me that you may have a problem with DNK2 power supply, its connections, or the DSK Display control board. There are several ref. voltages on the DNK supply board that need to be checked properly. Some voltages will be different when the x23 and x26 plugs are inserted or not. I suggest that you contact a local electrical engineer and I may assist him over the phone while he is there.

By the way, there are 5 NTE supply boards, but their output voltages are all different. You may have dammaged something else in the process of swapping.

When we swapped the "ZID" display the DNK board was attached as one unit(or is there another board called the DNK2?),
We also swapped the DSK from the CPTronic.
As far as swapping NTE board per Heidelberg manual "The power supply boards are plug–location coded,
i.e. not until they are in their plug location do they
receive information via a reference voltage as to
what output voltage is to be generated.
The boards are identical in their construction and
can be interchanged."
Getting a electrical engineer sounds like a good idea at this point.

 

Good Part, when we called Heidelberg for help they didn't know or ask where we got the ZID from.
In hindsight they we're right this is way to complex to fix over the phone.
For most repairs they are very helpful.

 

Problem solved! Bad MWE board.
We called Heidelberg again and talk to someone who really knew his stuff.
Note: on our press they're are two MWE boards if one is bad swapping won't change the problem,
they work in unison.
