I am trying to control a Opto 22 240D45 DC Control solid state replay with a micro controller. However before I hooked it up to the micro controller I though i would simply apply a DC voltage to the control input. I was expecting that in doing this the output (pins 1,2) would be short together. However when ever I do this no matter what DC voltage I apply the output pings never short together.
I am misunderstanding what this relay is suppose to do?
Below is the schemtic of the interal of the relay:

It is my udnerstanding that just as long as I hook up a 3V or high voltage to out 3,4 then pin 1,2 should short???? is this incorrect.
In the data sheet it says the Signal Pick-up voltage" is: 3VDC(32V allowed).
when I adjusted the controll voltage V34 the resistance between 1,2 does change but not much. I was expecting to go short.
What I am I doing wrong? What I am I not understanding?
