Description

Motor valve(s) connection

24 V DC power supply

For example: Single phase,

primary switched mode power

supply Type 1573

• Capacitive buffer module for moving to a safety position in case of power failure

• In order to be able to move to a safety position of the valve in the event of a power failure, the valve

must be supplied with voltage via the capacitive buffer module. In the event of a power failure, the

buffer module provides an output voltage of 18 V DC for a few seconds. The reduced input voltage

is detected by the valve and the safety position is approached accordingly. Up to 3 valves of Type

3280 or 2 valves of Type 3281 and Type 3285 can be connected to a buffer module. Factory setting

of the safety position: “valve closed”

• For standard version (functionality available from software version A.08): Adjustable via DIP switch

(when the operating direction is reversed, the safety position changes to “valve open”)

• For positioner and process controller variant (functionality available from software version A.06):

Adjustable via Bürkert Communicator (user-defined safety position)

8.2. Bürkert Communicator Software

Note:

• An adjustment of the valve by the Bürkert Communicator is only possible with the positioner or process controller variants.

• The corresponding communication software can be downloaded from the website Type 8920 .

The Bürkert Communicator is the most important software component of the EDIP (Efficient Device Integration Platform). Various features of

this universal tool simplify the configuration and parametrisation of devices equipped with a digital CANopen-based interface. With this tool,

the user has a complete overview of cyclic process values as well as acyclic diagnostic data. The integrated graphical programming

environment enables the creation of decentralised sub-system control functions. The connection to the PC is established with a USB-CAN

adapter. The adapter is available as an accessory (see “9.5. Ordering chart accessories” on page 15).

The Bürkert Communicator enables:

• Configuration, parametrisation and diagnosis of EDIP devices / networks

• Easy and comfortable mapping of cyclic values

• Graphical display of process values

• Firmware update for the connected EDIP devices

• Backup and restoring of device configurations
