Wiring in the edgebander

In a recent post I described an edgebander I had bought on Ebay. It's a monster and I just managed to get it into my shed and near the wiring on this past weekend.

Now I'm confused about the wiring. There's an obvious three phase line, to which I attached a plug and successfully ran the glue pot heaters and then the conveyer belt.

But there is another set of wires that I believe belong to the phase converter. This converter then runs the high frequency trimmers.

7 wires in a large soft plastic conduit (best I can do) emerge from the edgebander, and I don't know how to wire them. There are six black wires in two seperate bundles numbered 1,2,3, and 1,2,3, and an earth. Does anyone have experience with this?

Does the machine have a manufacturer number on it? Maybe possible to track a wiring diagram if that is the case!

I tried. I think the company, Manea, has moved into other types of machinery, textile manufacturing.

How about talking to the vendor to see if he can give you the sparky his father (in law?) might have used. It's a possibility. Otherwise you may have to get a multimeter and trace those wires to see what they hook up to. Possibly the machine was hard wired in (3 lots of 3 phase) to three seperate circuit breakers, although I can't imagine why.

That's what I might do, Mick. My impression is just that, that it wires to three separate circuit breakers. It seems to me that the frequency converter is an add-on, and that may explain why it needs three inlets. You'd think it would require one ....

The machine seems to be in good nick by the way. The conveyor belt runs well. I'm new to these machines and had to go through the process of finding out that:

the glue had to be melted before the belt could run :- .

that it needs air pressure before the belt will run.

that I had it running in reverse (always the way)

that when you're testing it over and over with the same bit of melamine that the glue starts building up on the edge and will distribute on the rollers :-

I'll keep you in touch about it.

Possibly the frequency convertor box houses two seperate units (top and bottom trimmers) and it was decided to wire them seperately. Also best bet is to clear up any glue on rollers etc sooner rather than later and make sure the air supply is filtered well.
