Type 8692, 8693 General Information Safety Instructions OperaTing insTrucTiOns The operating instructions describe the entire life cycle of the device. Keep these instructions in a location which is easily accessible to every user and make these instructions available to every new owner of the device. WarninG! The.operating.instructions.contain.important.safety.information! Failure to observe these instructions may result in hazardous situations.
• The device may be used only in conjunction with third-party devices and components recommended and authorised by Alfa Laval. • In view of the large number of options for use, it is essential prior to installation to study and, if necessary, to test whether the positioner is suitable for the specific application case.
Type 8692, 8693 General Information Safety Instructions Basic safeTy insTrucTiOns These safety instructions do not make allowance for any • contingencies and events which may arise during the installation, operation and maintenance of the devices. • local safety regulations; the operator is responsible for observing these regulations, also with reference to the installation personnel.
General Information Safety Instructions general infOrmaTiOn 4.1. contact address Contact your local Alfa Laval Company. 4.2. Warranty The warranty is only valid if the positioner Type 8692 and Type 8693 is used as intended in accordance with the specified application conditions. 4.3.

The control valve systems can be used for a wide range of control tasks in fluid technology and, depending on the application conditions, different process valves from the Alfa Laval range can be combined with the positioner. Angle-seat valves, diaphragm valves or ball valves fitted with a control cone are suitable.
Type 8692, 8693 Description of System, 5.1. models of the positioner The positioner is available in 2 versions: type 8692 - positioner with positioning control The position of the actuator (stroke) is regulated according to the position set-point value. The position set-point value is specified by an external uniform signal (or via field bus). type 8693 - positioner with process control The positioner is linked to a control circuit.
Type 8692, 8693 Description of System, sTrucTure Of The pOsiTiOner The positioners Type 8692 and Type 8693 consist of the micro-processor controlled electronics, the position mea- suring 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.

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. The 128x64 dot matrix graphics display enables you to display the set-point or actual value and to configure and parameterize via menu functions.

Type 8692, 8693 Description of System 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 General Rules (Appendix) 58.2. 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. The times Tu and Tg are derived from the progress of the actual value of the control variable.
