<p>Described is a fail-safe actuating system, comprising an actuator with an actuator housing and an output element. The output element is couplable to a controlled device. The fail-safe actuating system also comprises a biasing element, coupled to the actuator housing, which gets biased by a movement of the actuator housing in a first predefined direction; a locking device that locks the actuator housing for holding the biasing element in a biased state; and a controller configured to operate the actuator in a first operating mode, in which the actuator housing moves with respect to the output element for biasing the biasing element, and in the second operating mode, in which the output element moves with respect to the actuator housing for moving the controlled device.</p> |
