Hello Lee - I have just seen your wiring diagram and thought you might have a view on the following

I have just started getting the equipment together to add limit/home switches to my machine, and have found the following diagrams


The first has three wires running to all switches while the second has a serial connection to the switches which includes the emergency cutout. I can see how the second works , but am unable to see why the first has the three wires. - The connection board is the same as shown :



Are you able to comment on this set up and how it compares with your diagram

Would apprcieate anything you have to say

Thanks

Ken
