BDA in Offline Mode (or BDA Plus)

In offline mode, the BDA or BDA Plus is only connected to a laptop (represents all input/output devices). All the required parameters can be set in this operating mode and saved for later use (download to the circuit- breakers). No power is supplied via the laptop COM interface, which means that an additional power supply unit (24V DC) must be connected to the BDA.

BDA as a Hand-Held Device (or BDA Plus)

As a hand-held device, the BDA is operated by connecting it temporarily to the appropriate WL trip unit interface.

All circuit breakers in a system can be parameterized one after the other using just one BDA, and the parameter data saved to a laptop for further processing. In addition, all the diagnostic data of the circuit breaker can be read via the BDA.

An additional 24V DC power supply is required if the circuit breaker is not yet supplied with power (e.g. by means of an external 24V DC source on the CubicleBUS).
