Function Rollbar

All together a good and successful 2014 with a lot of hours of sunshine! I have a fundamental question about the function of the roll-over iron: The roll-over iron is probably triggered by the shearing position and/or by the crash sensor. I don’t want to simulate the crash now, but the slanting position. The switches on the rear axle are also activated on the lifting platform or when using a jack. Now the real question: Will the roll-over iron be triggered even in the stand/without ignition t or only when the vehicle is in motion? Manual operation works perfectly. Also the lowering when opening/closing the softtop. Does anyone have experience here?
