Hi Penguinair
I am not the best person to ask as my Electrical knowledge is very limited.
I read the diagram (may be wrong but see sensor outputs attachment above) as 24v supply but I was not able to
correctly decipher the pin outs and managed to smoke my board. !!**@@**!! The price for a replacement from
Emco was circa £300 GBP So I managed to replicate the boards function using off the shelf parts for about £5 GBP
(see attachments) Basically it is just 4 photo interrupter sensors used to produce the output signals. The schmitt
trigger inverter conditions the output to be either 0 or 1 nothing in between. Note the attached diagram only shows
the circuit for one sensor obviously the complete circuit requires four. The outputs were sent via a pokeys to a tool turret brain.
(see working solution @ machsupport forum/mach discussion/brains development /" compare immediate not working" BIGWING
www.machsupport.com/forum/index.php/topic,30316.0.htmlThis program followed the truth table to give a value for the current tool which I used in my modified M6Start.mls program
to index the turret.
However I am aware that there is a ready made control solution to the emco tool turret with a complete integrated package
in mach. I think the developers name is Andy Barrow. I think the company name is barrow dynamics but I might have my wires crossed there.
Best idea is to google it. I am sure if you get in touch with him he will know what the correct pin outs are for the Emco board
and save you a lot of work.
Cheers George
