Spontaneous Fault Indications
After a fault, the most important fault data are spontaneously displayed on the device. Address 610
FltDisp.LED/LCD allows to select whether the spontaneous fault indications will be updated on every fault
(Target on PU) or only in the case of faults involving a trip (Target on TRIP).
For devices with graphic display, use address 611 Spont. FltDisp. to specify whether or not a sponta-
neous fault message should appear automatically on the display (YES) or not (NO). For devices with text
display such messages will appear after a system fault in any event.

Reset of Stored LED / Relays
Pickup of a new protection function generally deletes all stored LED/relays so that only the information of the
latest fault is displayed at a time. The deletion of the stored LED and relays can be inhibited for a settable time
under address 625 T MIN LED HOLD. Any information occurring during this time are then combined with a
logical OR function.
Under address 610 FltDisp.LED/LCD also the information of the latest fault stored on LED and relays can
be deleted with the setting (Target on TRIP) unless this fault has lead to a trip command of the device.
NOTE

Setting the address 610 FltDisp.LED/LCD to (Target on TRIP) only makes sense if address 625 T
MIN LED HOLD is set to 0.
