Hi, I am New to LOGO and would like to switch from impulse relays in home lighting to LOGO! 8.

I hav only the problem that on my first project the N is going to the push butons in stead of the L and the N will go to the input of the logo.

1. Will this work, or wil he compare with what is on the N of the logo's power input? So comparing N with N is always 0V.

2. If not, can I just switch L1 and N on the power input so that he can compare the N on the input with the L1 on the N power input of the LOGO?

I hope its not to confusing ;-)

Yes you can just switch the Phase & N connection.

Don this several times.

Also tested that once at input 230v, and it just does nothing, buth further no problem.

I think he just measures the potential difference between F and N, and if you just put N to N there is just no potential difference. Or that would be my theory.
