  • Page 15 1 FUNCTION OF THE POSITIONER AND COMBINATION WITH VALVE TYPES Positioners Type 8692 and Type 8693 are electropneumatic positioner for pneumatically actuated control valves with single- acting or double-acting actuators. Together with the pneumatic actuator the positioner forms an optical and functional unit.
  • Page 16 Type 8692, 8693 Description of System Pneumatically actuated piston actuators and rotary actuators can be used as a actuator. Both single-acting and double-acting actuators are offered in combination with the positioner. For single-acting actuators, only one chamber is aerated and deaerated during actuation. The generated pressure works against a spring.
  • Page 17 Description of System 2 STRUCTURE OF THE POSITIONER The positioners Type 8692 and Type 8693 consist of the micro-processor controlled electronics, the position measuring system and the control system. The appliance is designed using three-wire technology. Operation of the positioner is controlled by four keys and a 128x64 dot matrix graphic display.
  • Page 18 Type 8692, 8693 Description of System 2.2 Features • Models for single-acting or double-acting valve actuators. • Position measuring system Non-contact and therefore non-wearing position measuring system. • Microprocessor-controlled electronics for signal processing, control and valve control. • Control module Operation of the device is controlled by four keys.
  • Page 19 Description of System 2.3 Function diagram of the positioner with single-acting actuator The black lines describe the function of the position controller (Type 8692). The process controller (Type 8693) includes the position controller and the functions which are illustrated in grey.
  • Page 20 Type 8692, 8693 Description of System 3 TYPE 8692 POSITIONER WITH POSITION CONTROLLER The position measuring system records the current position (POS) of the pneumatic actuator. The position controller compares this actual position value with the set-point value (CMD), which is definable as norm signal. In case of a control deviation (Xd1), a pulse-width modulated voltage signal is sent to the control system as a manipulated variable.

  • Page 23 Type 8692, 8693 Description of System 4 TYPE 8693 POSITIONER WITH PROCESS CONTROLLER If the positioner is operated with process controller Type 8693, the aforementioned position control becomes the subordinate auxiliary control circuit; this results in a cascade control. The process controller in the main control circuit of the positioner has a PID function.

    Type 8692, 8693 General Rules - Appendix 3 ADJUSTMENT RULES FOR PID CONTROLLERS The regulatory literature includes a series of adjustment rules which can be used in experimental ways to determine a favour- able setting for the controller parameters. To avoid incorrect settings, always observe the conditions under which the particular adjustment rules have been drawn up.

    Type 8692, 8693 General Rules - Appendix 3.2 Adjustment Rules according to Chien, Hrones and Reswick (Actuating Variable Jump Method) With this method the controller parameters are adjusted on the basis of the transient behaviour of the controlled system. An actuating variable jump of 100 % is output.
