The information regarding the position of the circuit breakers is not automatically de-
rived from the position logic according to Sub-section 6.17.2 (Figure 6-125). 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 Section 6.17.2 (Page
6-229).
The alarms of the device show the respective state of the test sequence.

the fault messages which are allocated to the local LEDs as well as the spontaneous
messages that are displayed via the LCD on the front of the device following a fault,
are stored following each fault detection of a protection function ( with PICKUP ), or if
storage only takes place if a trip command is issued ( with TRIP = "No trip no flag"-
