I have used verb read on fb app, object Article.
The action type for a read action should be 'news.reads', not just 'read'. Also, make sure you have checked the box for "Built-in FB Action".
I also tried the page load, but a new page did not trigger any action within the page load time 0 seconds.
You should set the timer to at least 10 seconds, per Facebook's requirements that there is a strong indication that the user is reading the page.
If that's still not working, please post screen shots of your Action and Object configuration in JFBConnect and we'll gladly help investigate what else may be wrong.
Thanks,
Alex
