Hi there,
I bought an old Klinger & Born (Elekra Beckum) table saw with what was described as having a faulty on/off switch. Right enough it doesnt start. I hear a mechanical type engagement from the switch and I can see the blade sort of ever so slightly oscillating which was slightly odd but its not rotating.
I thought it might be the switch so bought a (NVR) safety switch and e-stop. I see single phase motor with a capacitor and the cable going to the switch has 5 wires, brown, blue, earth and two black.
I've attached a few pics.
Q: I suppose the first question is what should I look at before assuming the switch is damaged. Does it have a fuse and an internal reset for example?
Q: If I can replace the switch with a more modern NVR which I have, see pic. What is the wiring for the two black wires?
Thanks for any help.
