8.2. Connecting Type 8743 with the Bürkert Communicator software

The Bürkert Communicator interface is based on CANopen. The appropriate bus termination is mandatory. Activate the termination resistor

switch on the büS stick.

Connection is established via the device’s micro USB socket (USB büS interface set 2 contains the required accessories).

Please note: no external power supply may be connected to the micro USB socket. The device must be provided with power as described

in chapter “5. Device / Process connections” on page 15.

8.3. Configuration management for easy device replacement

If a device needs to be replaced, the memory card can be removed from the defective device and inserted into the new one. This transfers

all data of the device to be replaced to the new device. The memory card is available as an accessory and must be ordered separately (see

“9.5. Ordering chart accessories” on page 21).

In order to successfully exchange the device, it is necessary that both the new device and the device to be replaced possess the same

device ID.

8.4. Web server for Industrial Ethernet variant

All Industrial Ethernet-based devices (except for the EtherCAT® protocol) from software version A.13.00.00 dispose of an integrated web

server. The server can be accessed via a web browser when entering the device’s IP address (factory setting IP192.168.1.100).

9.2. Recommendation regarding product selection

Note:

Use the Product Enquiry Form (see “9.4. Bürkert Product Enquiry Form” on page 21) for the device details and send it to us once

completed.

For the proper choice of the actuator orifice within the MFC, you need to know not only the required maximum flow rate Q

nom, but also the

pressure values directly before and after the MFC (p

1, p2) at Qnom. In general, these pressures are not the same as the overall inlet and outlet

pressures of the whole plant, because usually, additional flow resistors (tubing, additional shut-off valves, nozzles etc.) are present both

before and after the MFC.

Please use the Product Enquiry Form to indicate the pressures directly before and after the MFC. If these are unknown or not accessible to

measurement, estimates are to be made by taking into account the approximate pressure drops over the flow resistors before and after the

MFC, at Q

nom.flow rate. In addition, please quote the maximum inlet pressure p1 max to be encountered. This data is needed to make sure the

actuator is able to provide a close-tight function within all the specified modes of operation.
