4. Abruptly reverse the current to the setting of AngleRCA setup lagging the
voltage, to operate the forward directional element.
No ECHO and CS should appear.
5. Switch off the current and check that the ECHO and CS appear on the
corresponding binary output during 200ms after resetting the directional
element.
6. Switch off the CRL binary input.
7. Activate the BLOCK binary input.
8. Activate the CRL binary input.
No ECHO and CS should appear.
9. Switch off the polarizing voltage and reset the BLOCK and CRL binary
input.
If setting
WEI = Echo & Trip

1. Inject the polarizing voltage 3U0 to about 90% of the setting ( 3U0> )
operating voltage.
2. Activate the CRL binary input.
No ECHO, CS and TRWEI outputs should appear.
3. Increase the injected voltage to about 110% of the setting ( 3U0 ) operating
voltage.
4. Activate the CRL binary input.
5. Check that the ECHO, CS and TRWEI appear on the corresponding binary
output or on the local HMI.
6. Reset the CRL binary input.
7. Activate the BLOCK binary input.
8. Activate the CRL binary input.
No ECHO, CS and TRWEI outputs should appear.
9. Reset the CRL and BLOCK binary input.
10. Inject the polarizing voltage 3U0 to about 110% of the setting ( 3U0> ) and
adjust the phase angle between the voltage and current to (180°- AnglRCA )
setting, the current leads the voltage.
