10.5.9.2 Verifying the signals and settings
1. Inject current into the IED with an initial value below set value I>>>.
2. Increase the injected current until the TRIP signal appears and note the operate value of the
tested functionality.
3. Decrease the current slowly and note the reset value with TRIP signal resets.
10.5.9.3 Completing the test
Continue to test another function or end the test by changing the TestMode setting to Off. Restore
connections and settings to their original values, if they were changed for testing purposes.
10.6 Voltage protection
10.6.1 Two step undervoltage protection U2RWPTUV
Prepare the IED for verification of settings outlined in Section
Values of the logical signals for U2RWPTUV are available on the local HMI under Main menu /
Tests /Function status /Voltage protection /UnderVoltage2Step(27, 2(2U<)) /
U2RWPTUV(27,2(2U<)):x , where x = 1, 2.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
