Russ,
you are almost correct.
But I cannot find a way to fit a zero speed sensor. The turbine with the large inertia is itself mounted on a rotating arm. Picture yourself a kitchen dough mixer, only very large.
Krk's suggestion with a back-EMF sensing relay is a good idea.
That, or a zero speed sensor on the fan-end of the drive motor.
Or, simply a timer.
I tried to go back to PILZ' website to see if I could find more possibilities. No success, I just cannot find my way through that site.
