5. 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.
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 2300 or 2103 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.

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. 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.
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. The piston moves until there is an equilibrium of forces between compressive force and
spring force.
For double-acting actuators the chambers on both sides of the piston are pressurised. In this case, one chamber is
aerated when the other one is deaerated and vice versa. In this design, no spring is installed in the actuator.

6. 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.
The pneumatic control system for single or double-acting actuators consists of two or four solenoid valves.

6.2. 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. The 128x64 dot matrix graphics display enables you to
display the set-point or actual value and to configure and parameterize via menu functions.
• Control system
The control system consists of 2 solenoid valves for single-acting actuators or four solenoid valves for doubleacting actuators. In single-acting actuators, one valve serves for the aeration and another for the deaeration
of the pneumatic piston actuator. Double-acting actuators feature 2 valves for aeration and deaeration. 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 directaction model has an orifice of DN 0.6. On larger pneumatic actuators the solenoid valves feature diaphragm
reinforcers to increase the maximum flow and therefore improve the dynamics (DN 2.5).
• Position feedback (optional)
One inductive proximity switch.
When the valve reaches an upper or a lower position, this can be relayed e.g. to a PLC via binary outputs. By
means of set-screws, the operator can change the inductive proximity switch or limit positions.
• Pneumatic interfaces
1/4” connections with different thread forms
(G, NPT)
Hose plug-in connection
• Electrical interfaces
Circular plug-in connector or cable gland
18
• Body
The body of the positioner is protected from excessively high internal pressure, e.g. caused by leaks, by a
pressure limiting valve.

7. 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. 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.

8. 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. The process set-point value (SP) is specified as set-point value and
compared with the actual value (PV) of the process variable to be controlled. 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 determined by the process controller. 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. Z2 represents a disturbance variable.

16.3. Pneumatic connection of the positioner
DANGER!
Risk of injury from high pressure!
• Before dismounting pneumatic lines and valves, turn off the pressure and vent the lines.
Procedure:
Connect the control medium to the pilot air port (1)
(3 – 7 bar; instrument air, free of oil, water and dust).
Attach the exhaust air line or a silencer to the exhaust air port (3)
and, if available to the exhaust air port (3.1)
Important information for the problem-free functioning of the device:
• The installation must not cause back pressure to build up.
• Select a hose for the connection with an adequate cross-section.
• The exhaust air line must be designed in such a way that no water or other liquid can get into the
device through the exhaust air port (3) or (3.1).

Figure 27: Pneumatic Connection
Caution:(Exhaust air concept):
In compliance with protection class IP67, an exhaust air line must be installed in the dry area.
Keep the adjacent supply pressure always at least 0.5 – 1 bar above the pressure which is required to
move the actuator to its end position. This ensures that the control behavior is not extremely negatively
affected in the upper stroke range on account of too little pressure difference.
During operation keep the fluctuations of the pressure supply as low as possible (max. ±10 %). If fluctuations are greater, the control parameters measured with the X.TUNE function are not optimum.

20.4. Specifying the basic settings
When starting up the positioner for the first time, implement the following basic settings:
Specify the selected unit signal input for the set-point value default (INPUT)
(4 – 20 mA, 0 – 20 mA, 0 – 10 V or 0 – 5 V).
Start automatic adjustment of the position controller to the particular operating conditions (X.TUNE).
The exact description of the functions INPUT and X.TUNE can be found in the chapter entitled “20. 5
Description of the functions of the main menu”.
The basic settings for the positioner are implemented at the factory. During start-up, however, it is
essential to input the unit signal (INPUT) and run X.TUNE . Using the X.TUNE function, the positioner
automatically determines the optimum settings for the current operating conditions.
If the X.CONTROL is in the main menu while the auxiliary function X.TUNE is running, the position controller dead band DBND is determined automatically depending on the friction behaviour of the actuator
(see chapter entitled “22.3.9 Auxiliary functions - X.CONTROL”)

WARNING!
Danger due to the valve position changing when the X.TUNE function is running!
When the X.TUNE is running under operating pressure, there is an acute risk of injury.
• Never run X.TUNE while a process is running!
• Take appropriate measures to prevent the equipment from being accidentally actuated!
NOTE!
Avoid maladjustment of the controller due to an incorrect pilot pressure or applied operating medium
pressure!
• Run X.TUNE whenever the pilot pressure (= pneumatic auxiliary energy) is available during subsequent
operation.
• Run the X.TUNE function preferably without operating medium pressure to exclude interference caused by
flow forces.
The following functions are actuated automatically:
• Adjustment of the sensor signal to the (physical) stroke of the actuator used
• Determination of parameters for the PWM signals to control the solenoid valves integrated in the positioner
• Adjustment of the controller parameters for the position controller. Optimisation occurs according to the criteria
of a shortest possible correction time with a simultaneous freedom from overshoot.
Procedure:
You start Autotune by selecting X.TUNE in the main menu (MAIN) using the arrow keys.
Then hold down the right selection key (RUN) for approx. 3 seconds (countdown on display).

22. CONFIGURING THE AUXILIARY FUNCTIONS
The operating concept for the positioner is based on a strict division between basic and auxiliary functions.
When the device is delivered, only the basic functions are activated. They are used during the initial startup to implement basic settings specific to the device. They are adequate for normal operation. For more
demanding control tasks select and specifiy auxiliary functions at the configuration level.

The flow characteristic kV = f(s) indicates the flow of a valve, expressed by the kV value depending on the stroke s
of the actuator spindle. It is specified by the design of the valve seat and the seat seal. In general two types of flow
characteristics are implemented, the linear and the equal percentage.
In the case of linear characteristics identical k

The operating characteristic Q = f(s) specifies the correlation between the volumetric flow Q in the installed valve
and the stroke s. This characteristic has the properties of the pipelines, pumps and consumers. It therefore exhibits
a form which differs from the flow characteristic.

Standardised valve stroke [%] (POS) In the case of control tasks for closed-loop control
systems it is usually particular demands which are
placed on the course of the operating characteristic, e.g. linearity. For this reason it is occasionally
necessary to correct the course of the operating
characteristic in a suitable way. For this purpose the
positioner features a transfer element which implements different characteristics. These are used to
correct the operating characteristic.
Equal percentage characteristics 1:25, 1:33, 1:50,
25:1, 33:1 and 50:1 and a linear characteristic can
be set. Furthermore, a characteristic can be freely
programmed via nodes or automatically calibrated.
Position set-point value [%]
CMD
Inputting the freely programmable characteristic
The characteristic is defined via 21 nodes which are distributed uniformly via the position set-point values ranging from 0 – 100 %.
Their distance is 5 %. A freely selectable stroke (adjustment range 0 – 100 %) is assigned to each node. The difference between the stroke values of two adjacent nodes must not be larger than 20 %.
