14.1 Event counter (GGIO)
The function can be tested by connecting a binary input to the counter under test and from out-
side apply pulses to the counter. The speed of pulses must not exceed 10 per second. Normally
the counter will be tested in connection with tests on the function that the counter is connected
to, such as trip logic. When configured, test it together with the function which operates it. Trig
the function and check that the counter result is the same the number of operations.
14.2 Event function (EV)
Prepare the IED for verification of settings as outlined in section 1 "Overview" and section 2
"Preparing for test" in this chapter.
During testing, the IED can be set when in test mode from the PST. The functionality of the
event reporting during test mode is set from the PST as follows:
• Use event masks
• Report no events
• Report all events
In Test Mode, individual event blocks can be blocked from the PCM600.
Individually event blocks can also be blocked from the local HMI under the menu:
14.3 Fault locator (RFLO)
Prepare the IED for verification of settings as outlined in section 1 "Overview" and section 2
"Preparing for test" in this chapter.
The fault locator function depends on other functions to work properly, i.e. phase selection in-
formation 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 re-
corded disturbances can be found in the local HMI under the 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 se-
lection information.
