ok...I basically copied a Triac circuit right off of the datasheet....and it works as intended...except for a slight issue......that I'd like to remove.
When I first apply power to the entire circuit....the Triac fires for just a millisecond or so....(thus...energizing the load for a few milliseconds as well..)
Ugh. I don't care for that!!
I have checked using a O'scope the output to the Opto....(by setting the trigger so that if that line EVER goes above 1V...I'd catch it.)
It never does. The input to the Opto stays pulled to ground just as I had intended.....but the Triac still does its little 'blip'........
I did replace the Opto....but to no avail.
Is there something I should have added to prevent this action?
Outside of this issue, the circuit operates great.
Looking forward to comments on this...I am sure you guys have resolved this one before!!
Thanks!!!!
