Connection Type 3285 with Bürkert Communicator software
The interface to the “Bürkert Communicator” software tool is based on CANopen. A corresponding bus termination is mandatory.
For versions with standard signal interfaces, please activate the switchable terminating resistor on the büS stick. For versions with
büS / CANopen communication interface, this terminating resistor should not be switched on if the device is already integrated in a
properly terminated bus network.
• A büS stick is required to connect the motor valve to the “Bürkert Communicator” software tool. The büS stick sets contain the
necessary accessories.
• Versions with büS / CANopen communication interface are connected directly via the 5pin M12 plug (büS stick set 1 contains the
necessary accessories).
• Versions with standard signal interfaces are connected via the 8pin M12 plug on the device (büS stick set 1 + büS adapter;
socket 8pin-M12 to plug 5pin-M12 contain the necessary accessories).

8.2. Recommendation regarding product selection
Note:
• The conguration of the nominal diameter/orice is very important for proportional valves to ensure proper functioning within the
application. The nominal diameter/orice must be selected in such a way that on the one hand the desired ow range is achieved
and on the other hand a sucient part of the total pressure drop across the valve takes place when the valve is fully open.
• Reference value: pressure drop of the valve > 25 % of the total pressure drop
• Let Bürkert engineers advise you already in the planning phase!
