3 VM131 and only 1 push button ->?

Hello,

I purchased 3 VM131 modules and I want to control them with only ONE push button.
As soon as I connect the second VM131 module, the system becomes out of order.

Do you have any solution ?

Merci,

Thierry

VM131 circuits cannot have a common. Three units must be totally separated. Use either a pushbutton with three seperate contact sets or use a relay.

I have an similar problem. I would like to pilot two dimmers from two push buttons. But I have only three wires to pass my push buttons. Can I use one wire as common ?

schema :

.-------------- PB entry on VM131-1

|-------------- PB entry on VM131-1 & PB entry on VM131-2
PB2
`-------------- PB entry on VM131-2

thanks

No, please check previous post: None of the two pushbutton terminals may be connected in parallel with a terminal from a second printer.
You will have to use relays.
