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 an occurrence of a power system fault.
Functional Description
Command-dependent Messages "No Trip – No Flag"
The indication of messages masked to local LEDs and the generation of additional 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 7SD80 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.
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 will
be stored or reset.
