The information regarding the position of the circuit breakers is not automatically
derived from the position logic according to the above section. For the circuit breaker
test function (auto recloser) there are separate binary inputs for the switching status
feedback of the circuit breaker position. These must be taken into consideration when
allocating the binary inputs as mentioned in the previous section.
The alarms of the device show the respective state of the test sequence.
