ABB rec670 - Event Function EVENT; Fault Locator LMBRFLO

10.12.4 Event function EVENT
Prepare the IED for verification of settings as outlined in section
"Requirements" and
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.
10.12.5 Fault locator LMBRFLO
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.
