4. Abruptly reverse the current to
directional element.
5. Check that the IRVL output still is activated after the reversal with a time delay that complies
with the setting
6. Switch off the polarizing voltage and the current.

If setting
1. Inject the polarizing voltage 3V0 to (180° —
voltage and current to 155°, the current leads the voltage.
2. Inject current (180° —
INDir ).

3. Activate the CRL binary input.
4. Abruptly reverse the current to the setting of
the forward directional element.
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.
9. Switch off the polarizing voltage and reset the BLOCK and CRL binary input.
If setting
1. Inject the polarizing voltage 3V0 to about 90% of the setting (
2. Activate the CRL binary input.
3. Increase the injected voltage to about 110% of the setting (
4. Activate the CRL binary input.
