11.13.4 Event function EVENT
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 all events
In test mode, individual event blocks can be blocked from PCM600.
11.13.5 Limit counter L4UFCNT
The Limit counter function L4UFCNT can be tested by connecting a binary input to the
counter and applying pulses to the counter. The speed of the pulses must not exceed the
cycle time of the function. Normally the counter will be tested when testing the function
that the counter is connected to, such as the trip function. When the function is configured,
test it together with the function that operates it. Trigger the function and check that the
counter result corresponds to the number of operations.
11.13.5.1 Completing the test
Continue to test another function or end the test by changing the Test mode setting to Off.
Restore connections and settings to their original values, if they were changed for testing
purposes.
