This is an old setup with 1 of 2 the stateof-the-at is 2 out of 3 tip edundancy (both the potection system and the hydaulics) The safety system woks like a thee-way valve The tip system will simply de-pessuize the hydaulics system Most diect tips such as speed and condense pessue have been eplaced by 2/3 measuing devices (and tips) The 2/3 philosophy makes it possible to test the tip all the way to the hydaulics ESV movability test Lund Univesity / LTH / Enegy Sciences / TPE / Magnus Genup / Page 2
