Now that makes total sense to me. I can picture it being used now.

Thank you ever so much guys, I will pass the info on.

Hi everyone,

I have a challenge for you. One of our society members has acquired a piece of equipment that none of us can identify as to what it is or what it is used for.

It has two fine vernier scales, the silver piece on the right is spring loaded so it pivots outwards and springs back into place, to we think trap some object between the two points.There is what appears to be a attachment point on the back, maybe to fix it to a stand or other piece of equipment.

All this of course is pure conjecture as we have no idea whatsoever.

Your input would be very much appreciated.

Thank you.

Hi, sorry for the delay in getting back, but have wired the new controller in today and hey it works a treat! Been waiting ages for a friend to repair the old one but don't need it now hopefully. Thank you all for your various inputs and best regards.

Ron

Thanks very much for that John. Not quite sure what NVR switch is but will follow wiring from mains in through to the original board.

Hi guys, I apologise for the delay but the thing only arrived today due apparently to a smudged delivery address. I will try it when I get a minute or two. A question for John Rudd! All the terminals are marked +/- except power ones, so are these the same way round as the others John? I don't want to blow anything at this late stage! I also take it the earth will go to the screw near the end of the terminal block. As I said earlier I'm not too well up with electrics/electronics.

Will keep you posted John.

Hi, after all your help I have ordered one of them, at that price I've not much to loose as my machine is sitting idle anyway. Will let you know how it all works out later!

Thanks everyone.

Hi John, thanks for reply. I have contacted the seller to ask about the excitation query so will wait and see if I get a reply. I wondered if excitation was there just for a particular motor that needed it, ( I assume it's like a kick start) . As I said before I don't really understand electronics!

Hi, I don't know how to post a link. What I don't understand is it says the item is located in Dunfermline but the business is in China!

Hi guys, I have a chinese milling machine which is exactly the same as the Clarke CMD300 model from what I can tell from photos. It stopped working a while ago and I was told the power transistors were probably the cause. A club member took the control panel away with a view to fixing it. However, after replacing the transistors and connecting the panel to his machine he found there was still a fault somewhere that he can't pinpoint. A new panel is about £90 so I was wondering (not knowing anything about electronics) if the control panel I saw on e-bay might do the job. The main spec of my machine, taken off the motor plate is : 350w motor, DC 230v, 2.2A, class e (reversible)

The spec of the other controller is : Input AC180v-AC260c 50/60Hz, output current 4A, adapter power 50w~500w(110v output 300w, 220v output 500w) Fit motor voltage: 220v, Armature output volts DC0~90v/110v/220v, Excitation output volts DC100v-1A/DC200v-1A.

To my untrained eye it doesn't seem too far away, but would it do the job? If anyone out there could help with this I would be very grateful as it's over 12months since it stopped working!

Regards

Ron
