Authorized use
Type 8692, 8693
2. AUTHORIZED USE
Non-authorized use of the positioner Type 8692 and the
process controller Type 8693 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 Alfa
Laval.
• 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 8692 and 8693 only as intended.
2.1. Restrictions
If exporting the system/device, observe any existing restrictions.
2.2. Predictable misuse
• Do not feed any aggressive or flammable media into the pilot air port.
• Do not feed any liquids into the pilot air port.
• 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. Do not
paint the body parts or screws.

Basic safety instructions
Type 8692, 8693
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!
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.
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 supply voltage is present!

5. DESCRIPTION OF SYSTEM
Positioner or process controller
Actuator
Valve body
Process valve
Fig. 1: Structure 1
The positioner Type 8692 and the process controller Type 8693 are
electropneumatic positioner controllers for pneumatically actuated
control valves with single-action or double-action actuators.
The positioner, together with the pneumatic actuator, make up 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 condi-
tions, different process valves from the Alfa Laval range can be
combined with the positioner or with the process controller. Slanted
seat valves, straight seat control valves, diaphragm or ball valves are
suitable.

Technical data
Type 8692, 8693
5.1. Functions
Type 8692 - Position controller
The position of the actuator (stroke) is regulated according to the
position set-point value. The position set-point value can be spec-
ified by an external unit signal (or via field bus).
Type 8693 - Process controller
The process controller is integrated into a control loop. The stroke
of the valve is calculated from the process set-point value and the
process actual value via the control parameters (PID controller). The
process set-point value can be set by an external signal.
