@darkwood ok will do
But can you pls explain the common and NO on this GEFRAN unit? Is it giving outputs voltage?
No, look at what it is wired to in your case it seems to be the stop circuit loop, common is just a common voltage input value, if your system was 24v dc then common maybe the 24v dc + if that is the common value, once the output closes it sends this 24v + to where ever you want, you can also get negatively switch systems so in my example 24v dc - would be common, TBH the term common is very ambiguous and can mean different things in different circuits so don't put a label on it.
Again I am guessing as I have no literature on this controller.
I just wired a panel and have a common 24v+ rail which I tap off to various components, if you buy a standard timer with volts free relay output you get N/O - C - N/C ...you put the power onto the C- common and you switched output(s) on either N/O or N/C or both depending what you want to achieve.
This is a on a Machine just bought. We don’t use this device on other machines and it’s certainly not needed otherwise we would have kept it. Guy who had the machine before us kept it due to kind of raw material they used to run.
Trouble is this additional mechanism was installed by the last chap not by the manufacture of the machine.
