2.1.2.2 Setting Notes

Fault Display
A new pickup by a protection element generally turns off any previously lit LEDs so that only the latest fault is
displayed at any one time. It can be selected whether the stored LED displays and the spontaneous fault indi-
cations on the display appear upon the new pickup, or only after a new trip signal is issued. In order to select
the desired displaying mode, select the submenu Device in the SETTINGS menu. Under address 610
FltDisp.LED/LCD the two alternatives Target on PU and Target on TRIP ("No trip – no flag") can be
selected.
Use parameter 615 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 parameter 640 Start image DD. The pages available for each device version are listed in the Appendix
A.5.
Protection Interface Test Mode
To check the communication quality of the two 7SD80 devices during commissioning, set parameter 650 PDI
Test Mode to ON. The availability of the communication link via the protection interface is displayed as a sta-
tistical value (see Section 2.17.2).
