When it comes to testing future drive systems – for example in conjunction with hydrogen and high-voltage battery systems – and also when operating conventional testing systems, complexity, and thus also the requirements placed on system safety, increase due to the interlinking of a wide variety of systems. The safe operation of the entire system in compliance with statutory regulations while simultaneously maintaining a flexible operating concept pose a considerable challenge here. With the KS Functional Safety System (KS-FSS), KS Engineers have delivered an integrated operating and safety concept for the individual requirements of each system; starting with the design, then the planning, right through to operation and approval.
