The device requires some general information. This may be, for example, the type of annunciation to be
issued in the event of an occurrence of a power system fault.

Functional Description

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 7SJ80 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 generation of the reset command for stored indications. The instant the
device drops out, the presetting of parameter 610 FltDisp.LED/LCD decides whether the new fault
remains stored or is reset.

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

Setting Notes

Fault Messages
A new pickup of a protection function generally turns off any previously set light displays so that only the
latest fault is displayed at any one time. It can be selected whether the stored LED displays and the sponta-
neous messages on the display appear after the new pickup or only after a new trip signal is issued. In order to
select the desired mode of display, select the Device submenu in the SETTINGS menu. Under address 610
FltDisp.LED/LCD the two options Target on PU and Target on TRIP ("No trip – no flag") can be
selected.
Use parameter 611 Spont. FltDisp. to specify whether or not a spontaneous fault message should appear
automatically on the display (YES) or not (NO).
Selection of Default Display
The start page of the default display appearing after startup of the device can be selected in the device data
via parameter640 Start image DD. The pages available for each device version are listed in the Appendix
E Default Settings and Protocol-dependent
