Latching and non-latching targets
A latching operation target message remains on the display until manually
cleared or until replaced by a message of higher priority. However, if the fault
is stable and has not disappeared, the operation target message and the LED
(s) are not cleared. An operation target generated by a non-latching pickup is
automatically cleared when the element is reset.
Priority of operation target messages
The messages on the display have a certain priority order. If different types of
targets are activated simultaneously, the message with the highest priority
appears on the display.
The priority order of the messages:
1. CBFP
2. Trip
3. Pickup/Alarm
When several protection elements generate pickups, the last pickup/alarm
target message is displayed. When several protection stages trip, the first trip
target message is displayed until the time, as specified by the NEW TRIP
IND. setting value, has expired. After this, a new trip target message can
replace the old one. A hidden trip indication message can be brought forward
by pressing .

Disturbance recorder target

When the display is in the idle mode, an asterisk "*" indicating that the
disturbance recorder has been triggered and is ready to be unloaded, is shown
in the lower right-hand corner of the display.
