Abstract: The disclosure relates to a method and an arrangement for diagnosis of a final control element, which is actuated by a pneumatically operated actuating mechanism under the control of a control device, and which emits acoustic signals during conventional use. It is proposed to detect acoustic signals fed back into the pneumatic system of the actuating mechanism, and to derive from them the status data of the final control element. For this purpose, an acoustic sensor is arranged in the pneumatic-fluid supply line of the actuating mechanism, with the acoustic sensor being electrically connected to an analysis device. A pressure sensor is used as the acoustic sensor.

Abstract: A method for operating an actuating drive for controlling fittings. The actuating drive has an electric motor which is fed from a frequency converter and moves a fitting with a predetermined torque via a self-locking gearbox. In order to protect the actuating drive against unacceptable, destructive heating while maintaining operation in the surrounding process installation when an excess temperature occurs, the temperature of the actuating drive is measured during continuous operation, and the rotation speed of the electric motor is reduced as a function of the measured temperature while maintaining the torque. To this end, the amplitude and the frequency of the output voltage of the frequency converter are reduced in proportion to one another.
