Abstract:
A fail-safe brake system comprising:an actuating device that can be moved into different positions from a starting position,three sensors that generate a measuring signal which corresponds to the position of the actuating device independently of one another, wherein the first of the three sensors is supplied with energy by a first independent energy source via a first supply path, and wherein the second of the three sensors is supplied with energy by a second independent energy source via a second supply path, and whereinthe first and the second supply path are connected to one another via a connecting line which respectively contains two diodes or two elements that have the function of a diode, anda third supply path branches off the connecting line between the first and the second wherein the third supply path leads to the third sensor, and wherein the diodes are oriented in the connecting line in such a way that the flow-through direction of a first of said diodes extends from the first supply path to the third supply path and the flow-through direction of a second of said diodes extends from the second supply path to the third supply path.
