Van Dam 470DL Lid Printer

Mupwi,

If the manufacturer does not help, you will need additional help from the following sources:

1) A description of what each input and output is for.

2) An operator or user who can tell you what the operating sequence was, as well as what it would (should) do when an error or problem occurred (such as a jam or mis-aligned lid).

3) The format of any data it received, and what it was to do with this data. Similarly, the format of any data or reports it provides.

As you begin to get answers for the above, you can start to determine the flow of logic. If you have access to a working unit with its original controller, you can see its sequence and function.

It will take a lot of work and trial/error. Essentially you are engineering it from the beginning. I hope you have a big enough budget in time and/or money. I recently did a job for an industrial incinerator, with no copies of the logic or documentation. We began with drawings of the I/O, a knowledgeable operator, and the existing computer programs which took data from it for reporting purposes. It took a lot of time and fine-tuning, as well as patience from the people at the plant. For them, though, the result was a system which performed as well or better than before, was fully documented, and allowed them to meet all regulatory requirements.

Patience and best wishes--JMM
