the function and check that the counter result corresponds to the number of
operations.
9.11.6.1 Completing the test
GUID-325F040B-BADC-4281-B965-9B7D6BFA3E15 v1
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.

9.12.1 Pulse-counter logic PCFCNT
M13405-2 v7
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.
9.12.2 Function for energy calculation and demand handling
ETPMMTR
GUID-4FC03017-93BD-4B30-A874-487BF89971D5 v1
Prepare the IED for verification of settings as outlined in section ”Overview “ and
section ”Preparing for test“ in this chapter.
9.12.2.1 Verifying the settings
GUID-F8F0D384-BC70-48CA-817E-EB9BFBD68A54 v3
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.
