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

Description
Command-dependent Messages "No Trip – No Flag"
The indication of messages masked to local LEDs and the provision of spontaneous messages can be made
dependent on whether the device has issued a trip signal. This information is then not output if during a system
disturbance one or more protection functions have picked up but no tripping by the 7SJ61 resulted because the
fault was cleared by a different device (e.g. on another line). These messages are then limited to faults in the
line to be protected. 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. When the relay drops
off, stationary conditions (fault display Target on PU / Target on TRIP; Trip / No Trip) decide whether the new
fault will be stored or reset.

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 spontaneous
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

FltDisp.LED/LCD
the two options
Target on PU
and
Target on TRIP
("No trip – no flag") can be se-
lected.
