METHOD FOR CONTROLLING A VALVE ACTUATOR AND A VALVE ACTUATOR CONTROL DEVICE

摘要

A method for controlling a valve actuator, a valve actuator control device and a valve actuator assembly. The method includes the steps of providing a valve actuator control device, connecting the control device to a valve actuator with a signal transmitting wire, and supplying operating power to the valve actuator from the control device. The method further includes a step of transmitting control signals from the control device to the valve actuator via the signal transmitting wire in order to control the actuator. Hereby, configuration, control and maintenance of valve actuators are facilitated.
