R44 Starter Inhibitors

Hi Guys, Does anyone know exactly how the R44 starter inhibitor circuits work?

The rotor brake 'on' is obviously one, but then the clutch and low-rpm circuits also inhibit the starter in some manner don't they? whilst still facilitating a restart in flight if necessary. Could one accidentally engage the starter/shower of sparks (and associated ignition retardation etc...) in flight, or is this protected against?

I've been looking at the Electrical diagram but can't make 100% sense of it...

Cheers
