Start-up
8.2 Connecting the device to the Bürkert Communicator
The Bürkert Communicator can be connected to the device via a büS network or with the büS interface set.
→ Install the Bürkert Communicator on the PC.
→ Use the USB-büS-interface to establish the connection between the device and the PC.
Not required for the devices in a büS network.
→ Start the Bürkert Communicator.
→ In the menu bar click the icon
→
Select büS interface set
→ Complete.
The device is connected to Bürkert Communicator and is displayed in the navigation area .
8.3

Functions of the positioner and process controller

The device has various functions that can be changed via the Communicator software.

or büS via network.
The valve has a zero point shutdown, which guarantees the sealing
of the valve for input signals below a set threshold of the input signal.
The valve is closed at values below this threshold
If the power supply is interrupted, the valve remains in the respective
position. When the voltage is applied again, the control electronics
automatically detect the current valve position
With this auxiliary function, you select a transfer characteristic with
regard to the set-point value (set-point position, CMD)and valve
stroke(POS) for correcting the flow or operating characteristic
The positioner only responds from a control difference to be defined
Reversal of the effective direction of the set-point value
Definition of the safety position at set-point value input < 4 mA
Input of the opening and closing time
The physical control range is limited to defined areas
Simulation of set-point values for testing device functions
The standard signals are 4...20 mA; 0...20 mA; 0...5 V; 0...10 V
adjustable
The standard signals are 4...20 mA; 0...20 mA; 0...5 V; 0...10 V
adjustable
Changing the factory calibration of the signal input
With the digital variant, the device can receive communication via
büS/CANopen (e.g. set-point values/actual values)
