Hello all;.
This is my first post on the forum, so here goes!
I have a small single phase Myford lathe which works fine when hooked up directly to the mains via the manufacturers Live / Neutral terminal block at the rear. It also has a simple inbuilt on / off switch. Since there is almost zero inbuilt safety here, insofar as if the current was interrupted and the on / off switch was not returned to 'off' before the supply was restored, the machine would start unexpectedly.
So, I decided to install an NVR switch with an E-stop, with the intention of taking the output to the existing terminal block.
Now the machine will not work at all!
Reverting back to the original arrangement, everything is fine, so obviously I am not wiring up the new switch incorrectly somehow. I have bypassed each component to determine if any are faulty, but no success.
Enclosed is a photo of the new switch arrangement.
Can someone please explain how I wire this up to the point at which the supply enter the terminal block of the lathe?
If any more information or photos are necessary just let me know!
Cheers - Nick.
