Breaker Data Adapter (BDA)

Operating Instructions and Troubleshooting

WL Circuit Breaker

The BDA supports state-of-the- art communications technology. It can be implemented regardless of the operating system and browser used.

The instructions provided here, show you how to make particular settings. A troubleshooting table is included at the end to help you solve any problems.

Languages and Help

The BDA interface is in German and English. The language is selected every time the browser is started.

In addition to the HTML pages and Java applets, the BDA stores the accompanying help pages in different languages. The help pages can be called up where they are available via the question mark icon in the top right-hand corner of the screen. They are available whenever the BDA is activated. The help pages are available in German and English.

Offline/Online Mode

The BDA (and BDA Plus) can be run in two different operating modes.

Online mode

Online mode is activated automatically when the BDA is connected to a circuit breaker. In this mode, the current operating and diagnostic data, as well as the parameters are displayed and loaded directly to the circuit breaker after they have been changed. Online mode is indicated by a green CubicleBUS LED.

If the connection to the circuit breaker is interrupted, the BDA switches to offline mode. This also occurs if a file has been opened under "Parameter Transfer" or received from the circuit breaker.

Offline mode

If the BDA is supplied with 24V DC and is not connected to a circuit breaker, the BDA starts in Offline mode, indicated by the CubicleBUS LED not illuminated. Offline mode is used to configure the BDA even if it is not connected to a circuit breaker, and save this file for later use.

To switch from Offline to Online mode, first connect a circuit breaker. You then press either the "Online" or "Send Parameters" button in "Parameter Transfer".

Displaying Data

WL Circuit Breakers use "Property Bytes", which provide information on the required value, such as

whether it is available, or readable and/or writable. The display then changes depending on the property byte.

If a value is not available, for example, because the circuit breaker does not have any neutral conductor protection (N-conductor protection parameter), it is displayed as an empty white field with no outline.

If a value is available, the system differentiates between whether it is only readable or also writable. "Read Only" data is displayed in black on a gray background in a black, outlined field. If the value is also writable, the background is white.

Values that are available but not currently valid are displayed in red. This could be the case, for example, if the number of measured values available for calculating the long-term values of the current is insufficient because the circuit breaker has just been closed.

Figure 4-19The way data is displayed on the BDA pages depends on the property byte.

This tells you which data is read only, which data can be written, and which data is not available.
