Device, General Settings
To assure a correct functioning of the device, some general information is required, e.g. the form in which mes-
sages on power system faults are to be output.
If the device features a battery charger (ordering option), configure the respective data in the device data, too.
2.1.2.1 General Device Functions
Command-Dependent Messages "No Trip – No Flag"
The storage of indications assigned to local LEDs and the availability of spontaneous indications can be made
dependent on whether the device has issued a trip command. This information is then not issued if during a
system disturbance one or more protection functions have picked up but the 7SC80 did not trip because the
fault was cleared by another device (e.g. on another line). These messages are then limited to faults in the line
to be protected.
The following figure illustrates the creation of the reset command for stored messages. By the moment of the
device dropout, the presetting of the parameter 610 FltDisp.LED/LCD decides, whether the new fault is
stored or reset.

Spontaneous Indications
You can determine whether or not the most important data of a fault event are to be displayed automatically
after the fault has occurred (see also Subsection "Fault Indications" in Section "Auxiliary Functions").
