4. Switch the current infeed injection off. The function shall reset. Turn the current
on with the values corresponding to Test #3 and measure the time to activation
of signal TRZ2. This time shall be compared to tZ2.
5. Feed the IED with current and voltage corresponding to the apparent impedance:
Test #4, as shown in figure 12. Read the analog outputs for R and X and check
that this reading corresponds to the injected impedance. The signals START,
STZ2 and STZ1 shall be activated instantaneously and the signals TRIP, TRZ2
and TRZ1 shall be activated after the different set time delays.
6. Switch the current infeed injection off. The function shall reset. Turn the current
on with the values corresponding to Test #4 and measure the time to activation
of signal TRZ1. This time shall be compared to tZ1.

Completing the test

Continue to test another function or end the testing by setting the parameter TestMode
to Off under Main menu/Tests/IED test mode/TESTMODE:1. If another function
is tested, then set the parameter Blocked to No under Main menu/Tests/Function test
modes/Impedance/LEXPDIS(40)/LEXPDIS:1 for the function, or for each
individual function in a chain, to be tested next. Remember to set the parameter
Blocked to Yes, for each individual function that has been tested.
