Authorized use
2. AUTHORIZED USE
Non-authorized use of the positioner Type 8694 may be a
hazard to people, nearby equipment and the environment.
• The device is designed to be mounted on pneumatic actuators
of process valves for the control of media.
• Do not expose the device to direct sunlight.
• Use according to the authorized data, operating conditions and
conditions of use specified in the contract documents and oper-
ating instructions. These are described in the chapter entitled
“6. Technical data”.
• The device may be used only in conjunction with third-party
devices and components recommended and authorized by
Bürkert.
• In view of the large number of options for use, before installa-
tion, it is essential to study and if necessary to test whether the
positioner is suitable for the actual use planned.
• Correct transportation, correct storage and installation and
careful use and maintenance are essential for reliable and fault-
less operation.
• Use the positioner Type 8694 only as intended.
2.1. Restrictions
If exporting the system/device, observe any existing restrictions.
3. 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.
Danger – high pressure!
• Before dismounting pneumatic lines and valves, turn off the
pressure and vent the lines.
Risk of electric shock!
• Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
• Observe applicable accident prevention and safety regulations
for electrical equipment!

Basic safety instructions
General hazardous situations.
To prevent injury, ensure:
• Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
• After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
• The device may be operated only when in perfect condition and
in consideration of the operating instructions.
• The general rules of technology apply to application planning
and operation of the device.
To prevent damage to property of the device, ensure:
• Do not feed any aggressive or flammable media into the pressure
supply connection.
• Do not feed any liquids into the pressure supply connection.
• Do not put any loads on the body (e.g. by placing objects on it or
standing on it).
• Do not make any external modifications to the device bodies.
NOTE!
Electrostatic sensitive components / modules!
The device contains electronic components which react sensitively
to electrostatic discharge (ESD). Contact with electrostatically
charged persons or objects is hazardous to these components. In
the worst case scenario, they will be destroyed immediately or will
fail after start-up.
• Observe the requirements in accordance with EN 61340-5-1
and 5-2 to minimize or avoid the possibility of damage caused by
sudden electrostatic discharge!
• Also ensure that you do not touch electronic components when
the power supply voltage is present!
The positioner Type 8694 was developed with due consider-
ation given to the accepted safety rules and is state-of-the-art.
Nevertheless, dangerous situations may occur.
Failure to observe this operating manual and its operating instructions
as well as unauthorized tampering with the device release us from
any liability and also invalidate the warranty covering the devices
and accessories!

5. STRUCTURE AND FUNCTION
Positioner
Actuator
Valve body
Actuator + Valve body = Process valve
Fig. 1: Structure 1
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 from the Bürkert range can be combined with
the positioner. Angle seat valves, straight seat valves, diaphragm valves
or ball valves are suitable.
The position of the actuator is regulated according to the position
set-point value. The nominal position value is specified by an external
standard signal.
