Event function EVENT

Prepare the IED for verification of settings as outlined in section
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.

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. Trig the
function and check that the counter result corresponds to the number of operations.

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.

Metering

Pulse-counter logic PCFCNT

The test of the Pulse-counter logic function PCFCNT requires the Parameter Setting
tool in PCM600 or an appropriate connection to the local HMI with the necessary
functionality. A known number of pulses with different frequencies are connected to
the pulse counter input. The test should be performed with settings Operation = On or
Operation = Off and the function blocked or unblocked. The pulse counter value is
then checked in PCM600 or on the local HMI.
