Accessories Description

Motor valve(s) connection

24 V DC power supply

For example: Single phase,

primary switched mode power

supply Type 1573

• Capacitive buer 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 buer module. In the event of a power

failure, the buer module provides an output voltage of 18V DC for a few seconds. The re-

duced input voltage is detected by the valve and the safety position is approached according-

ly. Up to 3 valves of Type 3280 or 2 valves of Type 3285 can be connected to a buer module.

Factory setting of the safety position: “valve closed”

• For standard version (functionality available as of software version A.08): adjustable via DIP

switches (for the reverse operating direction, the safety position changes to “valve open”.

• For positioner and process controller version (functionality available as of software version

A.06): adjustable via Bürkert Communicator (user-dened safety position)

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

Part of Bürkert’s new EDIP program (Ecient Device Integration Platform) is the Bürkert Communicator. This software can be run un-

der MS-Windows and it is available on Bürkert’s website for free. The Bürkert Communicator allows convenient system conguration

and parametrisation of all connected eld devices. An accessory part, the büS stick serves as the interface between computer and

process instruments (see “8.4. Ordering chart accessories” on page 12) The Communicator allows:

• Diagnostics

• Parameterisation

• Registration and storage of process data

• To watch graph of process

• To update rmware of the device connected

• Parameterisation of the integral positioner and (if available) process controller
