Introduction Introduction 1 1.1 Generalinformationaboutthepositioner The positioner is used to adjust and control pneumatic actuators. The controller operates electropneumatically with compressed air as an energy supply. Purpose For example, the positioner can be used to control valves as follows: S with linear actuator (figure 1-1, page 13) or S with part-turn actuator VDI/VDE 3845 (figure 1-2, page 13) Different mounting types are available for linear actuators: S NAMUR or IEC 534 S integrated

Design and Functional Principle DesignandMethodofOperation 2 The following chapter describes the mechanical and electrical design, the instrument components and method of operation of the positioner. 2.1 Overview Introduction The electropneumatic positioner forms a control system in connection with an actuator. The current position of the actuator is detected by a servo potentiometer and fed back as actual value x. The setpoint and actual value are output simultaneously on the display. The setpo

Design and Functional Principle spond even when the power supply fails or the electronics are defec- tive. The actuator can also be blocked or driven to its final positions depend- ing on the configuration for example by an external event via a digital input (DI2) on the alarm module. If you require electrically independent limit value messages from the standard controller, you will have to use the SIA module with the slot initiators instead of the alarm module. Communication with the controller
