11. Inject current in one phase to about 110% of the set operate current(IN>Dir ).12. Activate the CRL binary input.No ECHO and TRWEI should appear.13. Abruptly reverse the current to 65° lagging the voltage to operate the forwarddirectional element.No ECHO and TRWEI should appear.14. Switch the current off and check that the ECHO, CS and TRWEI appear onthe corresponding binary output during 200ms after resetting the directionalelement. If EF4PTOC also operates in forward direction, CS should beobtained.15. Switch the polarizing voltage off and reset the CRL binary input.9.9.5.3 Completing the test M13936-90 v5Continue to test another function or end the test by changing the TESTMODEsetting to Off. Restore connections and settings to their original values, if they werechanged for testing purposes.9.10 Logic SEMOD53577-1 v19.10.1 Tripping logic, common 3-phase output SMPPTRC SEMOD54375-102 v10Prepare the IED for verification of settings outlined in Section "Preparing the IEDto verify settings".This function is functionality tested together with other protection functions (linedifferential protection, earth-fault overcurrent protection, and so on) within theIED. It is recommended that the function is tested together with the autorecloserfunction, when built into the IED or when a separate external unit is used forreclosing purposes.9.10.1.1 3 phase operating mode SEMOD54375-106 v101.
