The device incorporates the main function groups - Position sensor - Electro-pneumatic control system - Microprocessor electronics The position sensor measures the current positions of the proportional valve. The microprocessor electronics continuously compare the current position (actual value) with a set-point position value specified via the standard signal input and supplies the result to the positioner/process controller. If there is a control difference, the electro-pneumatic control system corrects the actual position accordingly. For the service is a 128 x 6 dot matrix graphics display and a keypad with keys available. 6.2 Designs Type 8792, positioner The position of the actuator is regulated according to the position set-point value. The position set-point value is specified by an external standard signal (or via field bus) Type 879, process controller Type 879 also features a PID controller which, apart from actual position control, can also be used to implement process control 8

9 Description of System (e.g. level, pressure, flow rate, temperature) in the sense of a cascade control. The process controller is linked to a control circuit. The position set-point value of the valve is calculated from the process set-point value and the actual process value via the control parameters (PID controller). The process set-point value can be set by an external signal Type 879 remote operation with external position sensor In the case of this model the positioner has no position sensor in the form of a rotary position sensor, but an external remote sensor.
