Notice: The Call to Stop will always be evaluating the stop conditions, even when the
Generator Control is Disabled, so that the user can test the logic without starting the generator.
Furthermore, the Call to Stop will be evaluated even while the generator is stopped. If the Call
to Start is True when the generator shuts down, the generator will immediately startup again.
Therefore, care should be taken when defining start and stop conditions so that they do not
interfere with each other.
