ABSTRACT:
The invention pertains to a method for verifying the performance of a test of the functionality of an actuator (1) with a drive (2) and a valve (3a), where the valve (3a) can be moved by the drive (2), which uses a drive element (3) acting on the valve (3a); where the drive element (3) and thus the actuating element of the valve can be moved by means of a position controller (5) over a portion of the actuating distance to perform the partial-stroke freedom-of-movement test and thus to test the functionality of the actuator (1), and where the position controller (5) has a distance sensor (7)—the primary sensor—and a first evaluation unit (8) for evaluating and storing the signals of the distance sensor (7). According to the invention, a second evaluation unit (13a) is used, which detects the movement of the actuator (1) and simultaneously acquires and records a protocol of this movement, and in that a second sensor (11) connected to the second evaluation unit (13a) is used independently to detect the movement of the actuating element.
