| NVR switch not working |
| (1/3) > >> |
| NormanV:
Can somebody help me please. The NVR switch on my lathe has stopped working. It is forty years since I had a look inside one of these and I have forgotten everything I knew (it wasn't much!). If I press the plastic bit by the yellow label on the front the motor runs as normal but stops when I release it. When I press the start button nothing happens. Thanks in advance. |
| John Rudd:
Norman, I suspect the coil that holds it all together is open circuit..... You will probabky need to replace the nvr unit...... |
| NormanV:
Which part is the NVR unit? That was quick! |
| John Swift:
does this diagram help when you push the green N/O button the mains supply will energise the contactors coil providing both the red stop switch and motor overload switch is closed this will close a N/O contact wired in parallel with the start switch to maintain the coils supply until you push the stop button john |
| NormanV:
My question was a bit more basic. Is the nvr bit the lower of the two parts in the switch? |
