Triggering TRIAC via DC

[anso-engineer]

Hello, I am trying to simulate TRIAC and see strange results. So here is my questions:
1. Why I got on R2 node current as sinusoidal during the whole simulation time?
2. Why I have those values?

When energized, the optocoupler output is shorting the gate to MT1. This holds the TRIAC in the off state.

See page 3 of this datasheet for the correct connections:

Where is the DC supply for U2’s photo transistor side?
Don’t tell me it is V2. That supplies the LED side only.
The circuit as drawn will always be off.
