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.

UL 489, UL1066 specifications

Siemens UL1066 and UL489 are essential components in the landscape of electrical equipment, specifically in circuit protection and control. These standards ensure reliability, safety, and efficiency in various applications, including industrial, commercial, and residential settings.

The Siemens UL1066 is primarily focused on disconnect switches. These devices are designed to isolate electrical circuits, ensuring the safety of both personnel and equipment during maintenance or in case of faults. One of the key features of UL1066 disconnect switches is their high breaking capacity, enabling them to handle significant fault currents without failure. This characteristic is crucial in protecting downstream equipment from damage caused by short circuits. The UL1066 switches are also known for their robust construction, often featuring a metal enclosure that enhances durability and environmental resistance. Additionally, these switches can be operated manually or remotely, offering flexibility in operation and control.

On the other hand, Siemens UL489 circuit breakers provide comprehensive protection against overcurrents and short circuits. These devices not only interrupt fault currents but also protect connected devices from damage due to overload situations. Key features of UL489 circuit breakers include adjustable trip settings, which allow users to customize the response to overcurrent conditions based on specific application requirements. This adaptability makes them suitable for a wide range of environments, from large industrial plants to smaller commercial buildings.

Both UL1066 and UL489 products are constructed with advanced technologies, such as thermal-magnetic or electronic trip mechanisms in UL489 devices, ensuring precise and timely interruption of fault currents. These technologies promote energy efficiency and stability within electrical systems. In addition, many of these devices are equipped with indication features, providing clear visual status cues for quick assessment in emergency situations.

In terms of characteristics, both UL1066 and UL489 devices adhere to rigorous testing and certification processes to meet UL standards. This compliance assures users of their performance and reliability. Furthermore, the devices are designed to accommodate a wide range of operating temperatures and environmental conditions, making them versatile choices for various applications.

In summary, Siemens UL1066 and UL489 devices are paramount in ensuring safety and efficiency in electrical circuits. Their advanced features and robust construction make them indispensable in protecting both personnel and equipment in an array of industrial and commercial applications.
