Proximity limit switch problems

[davrich]

Right I've had another go at this.

Eddy I tried wiring as per your suggestion. The lights on the S box came on and Mach 3 seems to look right too. Only thing is the switch doesn't trip when I move it towards metal or anything else for that matter.

3 of my switches don't light up the box at all when wired up in the same way as the one which seems to work. Its making me wonder whether I have a batch of duff switches?

This is how Marchantdice explained the wiring:

I've just taken one of our S-Box controllers to bits, the wiring for the limit switches and e/stop is as follows

Switches	Connector	Control Board
Prox Switch - Browns	Pin 1	VCC
Prox Switch1 - Black	Pin 2	S1
Prox Switch2 - Black	Pin 3	S2
Prox Switch3 - Black	Pin 4	S3
Not Used	Pin 5	S4
E/Stop - Yellow Prox Switch - Blues	Pin 6	Ground
Not Used	Pin 7	Not Used
E/Stop - Green	Pin 8	E-Stop

I've added a picture of what I wired together.
