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.
Function for energy calculation and demand handling
ETPMMTR
Prepare the IED for verification of settings as outlined in section "Overview " and
section "Preparing for test" in this chapter.

Verifying the settings

Common test equipment can be used to determine the injection of current and voltage
and time measurement.
Verification of EAFACC & ERFACC output
1. Connect the test set for injection of three-phase currents and three phase voltage
to the appropriate current and voltage terminals of the IED.
2. Ensure the instantaneous values of active and reactive power from CVMMXN
function block are connected to ETPMMTR function block active and reactive
power inputs.
3. Enable the EnaAcc setting and set tEnergy as 1 minute.
4. Activate the STARTACC input and supply the IED with three phase currents and
voltages at their rated value.
5. Check that the ACCINPRG signal appears continuously.
6. Note the EAFACC and ERFACCvalue after 1 minute and compare it with
calculated energy value.
