There are four different software alternatives with which the IED can be ordered. The intention is that these configurations shall suit most applications with minor or no changes. The few changes required on binary input and outputs can be done from the signal matrix tool in the PCM600 engineering platform. The main protection functions are switched Off at delivery. Back-up functions that are not generally used are also set to Off. The configurations are:

• Single-breaker arrangement. Three-phase tripping arrangement.

• Single breaker arrangement. Single-phase tripping arrangement.

• Multi breaker arrangement. Three-phase tripping arrangement. • Multi breaker arrangement. Single-phase tripping arrangement. The Multi-breaker arrangement includes one-and-a-half and ring-breaker arrangements. The number of IO must be ordered to the application where more IO is foreseen for the single-phase tripping arrangements respectively the multi-breaker arrangement. The basic delivery includes one binary input module and one binary output module, which is sufficient for the default configured IO to trip and close circuit breaker. All IEDs can be reconfigured with the help of the ACT configuration tool in the PCM600 engineering platform.

The IED can be adapted to special applications and special logic can be developed, such as logic for automatic opening of disconnectors and closing of ring bays, automatic load transfer from one busbar to the other, and so on. On request, ABB is available to support the re-configuration work, either directly or to do the design checking. Optional functions and optional IO ordered will not be configured at delivery. It should be noted that the standard only includes one binary input and one binary output module and only the key functions such as tripping are connected to the outputs. The required total IO must be calculated and specified at ordering. Hardware modules are configured with the hardware configuration tool in the PCM600 engineering platform.
