Type 8694

System description

5SYSTEM DESCRIPTION

5.1Intended application area

The positioner Type 8694 is designed to be mounted on pneumatic actuators of process valves for the control of media.

5.2Function of the positioner and combination with valve types

Positioner Type 8694 is an electropneumatic position controller for pneumatically actuated control valves with single-acting actuators.

Together with the pneumatic actuator, the positioner forms a functional unit.

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 belonging to series 2103, 2300, 2301, 26xx or 27xx from the Bürkert range can be combined with the positioner. Angle-seat valves, diaphragm valves or ball valves fitted with a control cone are suitable.

“Figure 1” shows an overview of the possible combinations of positioner and different pneumatically actuated valves. Different actuator sizes and valve nominal widths, not illustrated here, are available for each type. More precise specifications can be found on the respective data sheets. The product range is being continuously expanded.

Type 8694

System description

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.

Pneumatically actuated piston actuators and rotary actuators can be used as an actuator. Single-acting actuators are offered in combination with the positioner.

For single-acting actuators, only one chamber is aerated and deaerated in the actuator. The generated pressure works against a spring. The piston moves until there is an equilibrium of forces between compressive force and spring force.

5.4Structure of the positioner

The positioner Type 8694 consists of the micro-processor controlled electronics, the position measuring system and the control system. The device is designed using three-wire technology. The positioner is operated via 2 keys and a 4-pole DIP switch. The pneumatic control system for single-acting actuators consists of 2 solenoid valves.

System description

5.4.2Features

•Models

for single-acting valve actuators.

•Position measuring system

Contactless and therefore wear-free position measuring system.

•Microprocessor-controlled electronics for signal processing, control and valve control.

•Control module

The device is controlled via 2 buttons and a 4-pole DIP switch. 2x 2-colored LEDs indicate different statuses of the device.

•Control system

The control system consists of 2 solenoid valves. One valve is used to aerate and another to deaerate the pneumatic actuator. The solenoid valves operate according to the rocker principle and are controlled with a

PWM voltage via the controller. Doing so achieves a higher flexibility with regard to actuator volume and final control speed. The direct-action model has an orifice of DN 0.6. In larger pneumatic actuators the solenoid valves feature diaphragm amplifiers to increase the maximum flow and therefore to improve the dynamics (DN 2.5).

• Position feedback (optional)

The position of the valve can be transmitted to the PLC via an analog 0/4-20 mA output.

• Binary input

If a voltage > 10 V is applied, SAFE POSITION is activated, i.e. the valve is moved to the safety position (factory setting, can be changed with communications software).

• Pneumatic interfaces

1/4“ connections with different thread forms (G, NPT)

hose plug-in connection

• Electrical interfaces

Circular plug-in connector or cable gland

Pneumatic interface

	Electrical interface

•Body

The body of the positioner is protected from excessively high internal pressure, e.g. due to leaks, by a pressure limiting valve.

•Communications interface

System description

5.5Type 8694 positioner (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 standard signal. In case of a control deviation (Xd1), a pulse-width modulated voltage signal is sent to the control system as a manipulated variable. If there is a positive control difference in single-acting actuators, the air inlet valve is controlled via output B1. If the control difference is negative, the bleed valve is controlled via output E1. In this way the position of the actuator is changed until control difference is 0. Z1 represents a disturbance variable.

Control and display elements

7CONTROL AND DISPLAY ELEMENTS

The following chapter describes the operating statuses as well as the control and display elements of the positioner. Further information on the operation of the positioner can be found in the chapter entitled “12 Start-up”.

7.1Operating status

AUTOMATIC (AUTO)

Normal controller mode is implemented and monitored in AUTOMATIC operating status. → LED 1 flashes green.

MANUAL

In MANUAL operating status the valve can be opened and closed manually via the keys. → LED 1 flashes red / green alternately.

DIP switch 4 can be used to switch between the two operating statuses AUTOMATIC and MANUAL.
