4. Compare the measured time with the set value tCoord.
5. Activate the CR binary input.
6. Check that the CRL output is activated when the CR input is activated.
7. Switch the fault current on (110% of the set operating current) and wait longer than the set value
tCoord.
8. Switch the fault current off.
9. Reset the CR binary input.
10. Activate the BLOCK digital input.
11. Switch the fault current on (110% of the set operating current) and wait for a period longer than the
set value tCoord.
12. Switch the fault current and the polarizing voltage off.
13. Reset the BLOCK digital input.
Permissive scheme
1. Inject the polarizing voltage 3V0, which is 5% of VBase (EF4PTOC, 51N67N) where the current is
lagging the voltage by 65°.
2. Inject current (65° lagging the voltage) into one phase at about 110% of the set operating current,
and switch the current off with the switch.
3. Switch the fault current on, (110% of the set operating current) and wait longer than the set value
tCoord.
4. Switch the fault current off.
5. Activate the CR binary input.
6. Switch the fault current on (110% of the set operating current) and measure the operating time of
the ECPSCH (85) logic.
Use the TRIP signal from the configured binary output to stop the timer.
7. Compare the measured time with the setting for tCoord.
8. Activate the BLOCK digital input.
9. Switch the fault current on (110% of the set operating current) and wait for a period longer than the
set value tCoord.
10. Switch the fault current and the polarizing voltage off.
11. Reset the CR binary input and the BLOCK digital input.
