Thank you for the hints.
Though in case of of the comparator and extractor it's the same as for the grinder: It has a signal'strength of 0 while the machine works and gives out a signal'strength 15 when it has nothing more to do.
In the case of the grinder it works perfectly. When the grinder is empty it emits a signal and stops the engine, as soon as you put new items to grind into it the signal stops immediatly and the engine starts again.
In case of the extractor the behaviour is a bit weird. It does emit the signal in different cases, like when the chunk got unloaded and reloaded, when the server starts and of course when it's work is done.
However the machine fails to stop it's signal when you put in new items to process into it. (no matter the slot you use for the current processing). At least as long as the extractor has no power.
Once the extractor has power (like breaking a piece of redstone by hand and directly placing it down again) the signal works normally again.
Shown in these two screenshots:
There was no change in the extractor itself between these two screenshots (it had the same item in it's last slot to process), I just broke one redstone dust and placed it down again so the engine started and with it's power the redstone signal behaves again.
Of course I'm still very earlygame when it comes to rotarycraft (as seen, I still have a very test-like setup not even a building for it) so later I guess it will change alot with flywheels and everything.
I just asked mainly cause it confused me. The grinder works perfectly with it's redstone-signal update (even when the engine stands still), but the extractor needs power to update the redstone signal.
breaking the redstone and replacing it is of course no problem at this point. So it's not a big deal, but good to know for future planning when it comes to fuel-saving.
