9.11.4 Event function EVENT
M11751-2 v5
Prepare the IED for verification of settings as outlined in section "Preparing for
test" in this chapter.
During testing, the IED can be set when in test mode from PST. The functionality
of the event reporting during test mode is set in the Parameter Setting tool in
PCM600.
• Use event masks
• Report no events
• Report all events
In test mode, individual event blocks can be blocked from PCM600.
9.11.5 Fault locator LMBRFLO
M14955-2 v7
Prepare the IED for verification of settings outlined in Section "Preparing the IED
to verify settings" .
The Fault locator function LMBRFLO depends on other functions to work
properly, that is, phase selection information from distance protection function and
analog information supplied by the trip value recorder function. Check that proper
binary start and phase selection signals are connected and voltage and current
signals are configured (parameter settings).
The result is displayed on the local HMI or via PCM600. Distances to faults for the
last 100 recorded disturbances can be found on the local HMI under
Main menu/
Disturbance Records/Disturbance #n(n = 1–100)/General Information
If PCM600 is used, the result is displayed on the recording list after upload,
including loop selection information.
