7. Switch the fault current on (110% of the set operating current) and wait longer than the
set value
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

Permissive scheme
1. Inject the polarizing voltage 3U0, which is 5% of
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
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 logic.
Use the TRIP signal from the configured binary output to stop the timer.
7. Compare the measured time with the setting for
