Breaker Data Adapter (BDA)

WL Circuit Breaker

Password Protection

All write actions that would result in a change to the status or a parameter in the circuit breaker are password protected. This ensures that parameters cannot be changed and switching is impossible without this password.

Note: The electronic relays of the COM16 module are required to open and close the WL via the BDA.

The default password is

"sentron"

This can be changed by choosing "Extras > Password" in the BDA tree (recommended). You have to enter the new password twice. When you click OK, the BDA asks you for the old password.

If you have forgotten it, it can be reset by means of a master password. To do so, contact Technical Assistance at 1-800-964-4114 seainfo@sea.siemens.com

Operation Example

This example describes the functionality of the BDA. If you want to set the MODBUS address of the COM16 module for a WL Circuit Breaker, open the Communication node by choosing "Device Parameters

>Circuit Breaker". Then click the input/output field next to the MODBUS address and edit it with the new address. Once you have changed this parameter and exited the field, the outline turns blue to indicate parameters that have not yet been transferred to the circuit breaker.

You can then change other parameters. If you want to transfer the modified parameters to the circuit breaker, click OK on this page.

If the parameter transfer process is the first write action in this session, the system prompts you to enter the password. Once you have entered the password successfully, the data is transmitted to the circuit breaker.

If you want to reset the modified parameters, click the "Undo" button.

If you exit the parameters page without clicking OK, the changes are ignored.

Printing

Since Java applets are used, the normal print function in your browser on the parameter pages will not provide a satisfactory printout.

If you want to print the parameters for documentation purposes, open the pages to be printed from the tree in the BDA. All the parameter pages are displayed again under "Extras > Print", and you can print them individually as required using the print menu in your browser.

Comparing Parameters

The parameter comparison function is used to check whether the parameters set in WL Config or the BDA match those in the device. The following parameters are checked:

•Protection parameters A and B

•Extended protection function parameters

•Threshold value settings

•Measurement function settings

•Communication parameters

•Settings for the configurable output module

The parameter comparison function can be used, for example, to ensure that the set parameters are transferred without any errors once they have been downloaded to the device.

It is not possible to determine whether the parameters and settings loaded to the device have actually been transferred. This is because, for example:

•BDA just forwards parameter changes. Whether a parameter is correct can only be verified in the memory location (e.g. in the trip unit). If this changes the value because one has exceeded the maximum value, for example, the modified value is reported back to the BDA. This discrepancy would be detected when a subsequent parameter comparison is performed.

•In the BDA interface, not all values regarding the differences between minimum/maximum values and other parameters are checked. This means that a parameter could be entered that cannot be copied in the trip unit in its current form.
