Hello guys. Im working on a dimmer. Ive read up on triacs and optocouplers but i cannot figure out how pic related is going to work. Ive cutted out "not necessary" elements according to description on pic.

So heres how i see it. i turn on the LED inside MOC3021, it lights up and now optotriac inside MOC connects as long as the LED is on. Now how on earth is that supposed to launch the triac outside MOC? I mean theres no voltage betewen gate and the other pin.
