6. Activate input CLOSECMD on CCRPLD function block and measure the
operating time of the CCRPLD protection.
7. Set measured current in one phase to 110% of CurrRelLevel
8. Deactivate input CLOSECMD. Set measured current in one phase to 90% of
CurrRelLevel. Activate CLOSECMD.
NO TRIP signal should appear.
9. Repeat point 4 and 5 using OPENCMD instead of CLOSECMD. Set all three
currents to 110% of CurrRelLevel. Activate CLOSECMD.
NO TRIP signal should appear due to symmetrical condition.
10. Deactivate the CLOSECMD. Set measured current in one phase to 120% of
the CurrUnsymmLevel compared to the other two phases.
11. Set the two other phase currents to 0.
12. Activate CLOSECMD and measure the operating time of the CCRPLD
protection.
Use the TRIP signal from the configured binary out put stop the timer.
13. Deactivate the CLOSECMD. Set measured current in one phase to 80% of the
CurrUnsymmLevel.
14. Set the two other phase currents to 0.
15. Activate CLOSECMD.
NO TRIP signal should appear.

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/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No, under Main menu/
Tests/Function test modes/<Function group>/<Function>/<1:Function> 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.

Broken conductor check BRCPTOC

Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals are available on the local HMI under: Main menu/
Tests/Function status/<Function group>/<Function>/<1:Function>. The Signal
monitoring tool in PCM600 shows the same signals that are available on the LHMI.
