3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the assembly, operation, and maintenance.
• local safety regulations – the operator is responsible for observing these regulations, also in relation to the installation personnel.
Risk of injury from high pressure.
▶ Before loosening lines and valves, cut off the pressure and deaerate or drain lines.
Risk of injury due to electrical shock.
▶ Before working on the system or device, switch off and isolate the power supply to prevent reactivation of the

5 PRODUCT DESCRIPTION
5.1 Intended use
The motor valve Type 3280 and 3285 is designed for controlling the flow rate of liquid and gaseous media. Only
clean, liquid or gaseous medium, which does not react with the bodies and sealing materials, may be controlled.
NOTE!
Unsuitable medium will damage the body and the seals.
Unsuitable medium may damage the body and the seals.
• Use suitable medium only.
• Check chemical compatibility in individual cases.
5.2 Properties
The regulation of the flow or switching of the valve is regulated with the aid of a stepper motor actuator which is
controlled by the integrated electronic control system. Therefore, no external motor control is required for step control.
Basic functions of the control electronics:
• Control of the valve opening by processing the external set-point values
• Output of the valve states via the LED display
• Position detection after power failure
- if power fails, the current position of the valve is retained
- when power is restored, the internal control electronics automatically detects it’s current position
• Reduction in the energy consumption
- The valve is designed to hold its position without the active use of the motor. As soon as the desired position
is achieved, motor is turned off and the valve uses only fraction of power required to move the valve.

5.3 Structure and function
5.3.1 Electromotive seat valve Type 3280
The valve spindle is driven by a stepper motor. The angular movement of the motor is converted to translational
movement with the aid of a threaded spindle. The valve spindle is connected rigidly to the threaded spindle. The
valve spindle is connected to a control cone.

5.3.2 Electromotive disk valve Type 3285
The disk valve consists of a stepper motor with gearbox which transfers the rotational torque to the actuator shaft
via coupling. The actuator shaft has control/shut-off disc attached to it. A fixed disk with a mouth attached to the
body is used as a valve seat. Control/shut-off disc is pressed onto the fixed disk by a supporting spring. The actuator
turns the control/shut-off disc about 180° above the fixes disc and opens or closes the valve seat.

There are 2 versions of the positioner and the process controller:
- Analog: Set-point values are transmitted in analog mode via the standard signals,
- Digital: Set-point values are transmitted in digital mode via CANopen/büS.
The versions can be identified on the connector diagram. For this, see chapter “7.2”.
5.4.1 Electric control
The motor valves 3280 and 3285 feature an electromotive actuator with an electric control.
The device version is stated on the type label: G means on-off, 0 resp. H means control valve, C means
positioner and D stands for process controller.
Standard device:
• On-Off: By processing the external set-point values the valve is switching.
• Control valve: The device converts a external standard signal, set-point position to a valve position.
Both valve end positions are indicated by the LED status. Additionally, the digital output indicates when the closed
valve position has been achieved.
Positioner:
The position controller version converts a set-point position to a valve position. The position of the actuator is controlled according to the position set-point value. The current position (POS) of the electromotive valve is recorded
by the position measuring system. The position controller compares this position actual value to the set-point value
(CMD) specified as the standard signal. In case of a control difference (Xd1), the motor control signal is sent to the
actuating drive as the actuating variable. Z1 is a disturbance value.

Product description
Type 3280, 3285
Both valve end positions are indicated by the LED status. Moreover, the position actual value recorded using the
position measuring system is output via the M12 circular plug-in connector.
It is possible to communicate with the device digitally via CANopen* or büS**.
* CANopen - A CAN-based fieldbus (Controller Area Network) used in automation technology to link
devices.
** büS - A CANopen-based fieldbus with additional functions.
The positioner version also features some special functions (see chapter “8.3.1”), which can be set up using the
Bürkert Communicator.
The operating instructions for the Bürkert Communicator can be found at www.burkert.com
Process controller:
The additionally implemented PID controller can perform not only the actual position control but also a process
control in the sense of a cascade control.

Product description
Type 3280, 3285
The process controller is integrated in a control circuit. The position set-point value of the valve is calculated from
the process set-point value and the process actual value using the control parameters (PID controller). The process
set-point value can be specified by an external signal.
During the process control the position control mentioned above becomes the subordinate auxiliary control circuit;
this results in a cascade control. The process controller in the main control circuit has a PID function. The process
set-point value (SP) is specified as a set-point value and is compared with the actual value (PV) of the process
variable to be controlled. The position measuring system records the current position (POS) of the electromotive
linear actuator. This position actual value is compared by the position controller with the set-point value (CMD)
specified by the process controller. If there is a control difference (Xd1), the actual position (POS) and therefore
the valve opening are changed by the control variable (CTRL). Z2 represents a disturbance variable.
It is possible to communicate with the device digitally via CANopen* or büS**.
* CANopen - A CAN-based fieldbus (Controller Area Network) used in automation technology to link
devices.
** büS - A CANopen-based fieldbus with additional functions.
The positioner version also features some special functions (see chapter “8.3.1”), which can be set up using the
