Step 4: Gradually decrease the magnitude all three phase voltages until OUT2 closes. Record the time
to trip (OUT1 closes). Verify that the 21-1-AB, 21-1-BC, and 21-1-CA targets are displayed on
the front-panel display. Increase the voltage until OUT2 opens. Reset the target.
Step 5: Repeat step 4 for the time delays in the second and third rows of Table 231. Record the results.
Timing accuracy is 0.5% or 2 cycles, whichever is greater.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 21-2.
