Warco WM250

If you can scan the wiring diagram, we can advise ( Les, myself, anyone else with a bit of knowledge of elektrikery) how best to proceed......

Having scanned the wiring diagram it has dawned on me that I do not know how to get it into a post, never having needed to before. I know that it can be done from an album but as the only way to upload to an album is by JPEG format, it does not help me. This is a learning curve I did not anticipate..

.

If you upload it to an album somebody here will post it into the forum for you.

Dusty,

Send me a private message with your email address, I'll email you back with mine, then you can send me the scanned drawing.

I'll take a look and advise you on what to check.....unless you have an alternative...

Nick,

I think what Dusty means is that the scan is perhaps a pdf rather than a jpeg?? Ergo it is not permitted as a valid format.....but then I could absolutely wrong!!

John You are right it would not let me load into an album in fact I think it is HTML. PM sent.

If it's pdf, I can very easily convert it to jpeg

... I don't wish to tread on your toes, John Rudd, it's just an offer.

Dusty - Fraid I cannot guide you on circuits etc as I am not a sparky wizard like Les and John. However, my WM250 has a history of electrical problems and each time it packed up it was because the speed control board had gone faulty. Presently on my third board.

I have mentioned on here before that WARCO advise that when using the lathe the speed control knob MUST be set to zero before starting AND stopping the lathe (same advise applies to my WARCO WM16 mill.) I have operated the lathe (and mill) under these conditions since fitting the last speed control board in Januarylast year and the lathe still works - phew! The only thing that bothers me is the ON button constantly needs to be pressed - up to three times - to get the motor started. Its something I can live with but it is annoying.

I hope you get your machine sorted soon and trust you will not have to replace the speed control board. My last one set me back £109.80 - that's a lot of whisky!!!

Nick,Michael.....

I might be a wizz when it comes to leccy stuff ( As most of us, I have my linitations...  )

But I do accept my limitations when it comes to 'pooter stuff, so any help in this regard is very welcome and I'm sure Dusty joins me in saying this if it results in his lathe going again....

John,

... Probably easiest to forward Dusty's file direct to me.

MichaelG.

a P.M with my eMail address is on the way to you.

A workaround for converting anything (more or less) to jpeg is to take a screen shot of the PDF page/diagram/whatever by pressing Ctl and PrtScn simultaneously. Then open up the windows Paint program and hit Edit/paste. The screen shot will appear and can be cropped etc. and saved as a .jpg

This is one of the things that's changed in Windows 10, at least on my machine. If ctrrl + prtscn doesn't work try Windows Key + Print Screen instead. Even better is the snipping tool, (search for 'snipping' ) - it allows you to save a snapshot as a jpg directly.

Hi Rik It's interesting regarding start stop procedures that you outlined. My machine is now some 8yrs old and I have never used the speed control at minimum for starting and stopping. I have just gone through the operators manual and surprise, surprise nothing about that. Like you I am not very good with that lektricity stuff, now if it is a mechanical problem that's different. When I retired the seminar that I went on, one of the speakers said about saving for a rainy day, and most people don't recognise the rainy day. I can see a rainy day looming and Warco may get an order.

From the Armchair ...

Michael,

Indebted to you, thanks.

@Dusty,

Dusty with your trusty multimeter set to Ohms( resistance range), with say the Red meter lead connected to the N pin on your mains plug, connect the remaining Black lead to pin 14 on the nvr switch....you should have a reading if a few thousand ohms ( you may need to press the Green go button ), this should be the coils resistance.....

Michael John,

Thank you gentlemen I will perform said test once I have done those things the boss requires of me.

Dusty,

If as I suspect the nvr switch is faulty, if yours is KJD17B with 5 connections, then this one

Should fit nicely....

I measure 4.5 kilohms on a new nvr switch.....

John, I have carried out the test and am a bit confused with what I found. Connected as you instructed I got a series of numbers flash up and then it returned to zero's where it remained. This is in both the neutral position and with the green button pressed. I did not get a steady reading other than the zero's.
