Completing the test

Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.

Metering

11.14.1

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 = Enable or Operation = Disable and the function blocked or unblocked. The pulse
counter value is then checked in PCM600 or on the local HMI.
11.14.2

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.
11.14.2.1

Verifying the settings

Common test equipment can be used to determine the injection of current and voltage and time
measurement.
