Abstract: An actuator assembly is disclosed, which includes a power unit, an actuator powered by the power unit, the power unit being configured to provide a work motion of the actuator, a motion sensor, a timing unit for measuring an immobility time of the actuator, a safety unit for selectively placing the actuator assembly into an operational state and a safety state in which the work motion of the actuator can be prevented, the safety unit being configured to prevent the operational state of the actuator assembly in case the immobility time of the actuator exceeds a predetermined process safety time. The actuator assembly can include an activation unit configured to control the power unit to provide an activation motion of the actuator in case the immobility time exceeds a predetermined activation time.
