  Type 8692, 8693 General Information Safety Instructions 1 THE OPERATING INSTRUCTIONS The operating instructions describe the entire life cycle of the device. Keep these instructions in a location which is easily acces- sible to every user and make these instructions available to every new owner of the device.
• Page 10
  If exporting the system/device, observe any existing restrictions. 2.2 Foreseeable Misuse • The positioner Type 8692 and Type 8693 must not be used in areas where there is a risk of explosion. • Do not introduce any aggressive or flammable media into the system’s media connections.
• Page 11
  Also ensure that you do not touch electronic components when the power supply voltage is present! The positioners Type 8692 and Type 8693 were developed with due consideration given to the accepted safety rules and are state-of-the-art. However, dangers can still arise.

  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 128×64 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.

  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.
