Wiring Diagram check

How about now ? I moved the buzzer to the limits circuit. When you press the override switch, it does have power, right ?

Wrong first why don't you change the markings on the BOB so that they mean something correct ie you are showing that you are connecting the home switches to a Z limit etc.
You have now connected the buzzer in series with the relay coil!!

Here is the updated BOB input names. Sorry for the confusion I just copied the part setup from the manual. But they were actually not relevant.

What's wrong with connecting the buzzer in series ? If you explain to me the role of the override switch and how it works then i'll probably be able to understand what is not right in my diagram :(
Here is the QElectrotech file, if that can be of any help :)

1. It is not a good practice to derive power feed in this way.
2. The buzzer will not pass enough current to pull in the relay.

The BOB input names are relevant especially when you are asking basic questions.

I believe you are using two 12V fans in series so that you can power them from a 24V supply now have a look at the drawing re the buzzer and the relay coil and see if you can work that out. (I am not trying to be difficult but you have to fully understand the reason) clue is you are halving the voltage with the fans..
.
The purpose of the override switch is simply to provide a path to ground to energise the relay in the absence of a limit being tripped ie opened.

Alright, I get it now :) Wiring the buzzer in series drops the voltage in half, therefore both the relay and buzzer get 12V, which obviously isn't enough for the relay. So, I need to wire relay and buzzer in parallel and the SPDT switch allows opening the override line that bypasses all switches PLUS a parallel line where the buzzer is. Back to physics 101... ! :D Is this correct ?


EDIT:
I still have to make the changes for the contractor and for the VFD stop.

Ok You are getting there BUT if you look at the changeover switch how is the buzzer going to get its ground?
I feel it is better for you to work this out and then you will understand it.
Also if you will allow me to correct the name for the contactor instead of contractor (they are two different things in English.) I also wish I could speak your language as well

Whoops, forgot to pull that wire :) Sorry !!
I'm writing on a MacBook Air, OS X keeps correcting my words especially when it comes to electronics. Contactor gets automatically corrected to Contractor.. sorry :D Are you saying my English is bad ? Lord, didn't think it was that bad :'(
There you go :D
