    • The invention relates to a method for operating a positioner with a first input for an input variable W for prescribing a desired value, a second input for a controlled variable X, an output for a manipulated variable Y, and an actuator, which, dependent on the input variable W and the controlled variable X, generates an output signal for forming the manipulated variable Y, whereby the control method comprises detecting, during continuous monitoring, of an abnormal status of the signal representing the controlled variable X generating of an error signal that acts on a changeover unit. When an error signal of the error detection device is present, the method deactivates the actuator with respect to the signal of the positioner that represents the manipulated variable Y, and activates a controller by the changeover unit. Upon such controller activation, the method invokes the generation of a second output signal, which is allocated to the input variable W; the positioner comprises an error detection device which is connected to the second input for the controlled variable X. A changeover unit acts on the error detection device; and a controller, where, given the detection of an error of the signal representing the controlled variable X, the error detection device effectuates a switching of the changeover unit, so that the controller, and not the actuator, determines the manipulated variable Y.
