Step 3: Connect and apply 0.45 A to BE1-11m terminals D1 and D2 (A-phase).

Step 4: Step the A-phase current up to 0.75 A. Measure the time delay and record the result.

Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 133. Record the

results.

Step 6: (Optional.) Repeat steps 1 through 5 for the B-phase and C-phase current inputs.

Step 7: (Optional.) Repeat steps 1 through 6 for settings group 1, 2, and 3.

Step 8: (Optional.) Repeat steps 1 through 7 for 50-2, 50-3, 50-4, 50-5, and 50-6.

Step 9: (Optional.) Repeat steps 1 through 8 with CT Circuit 2 as the source for protection systems

equipped with two sets of CTs. In step 3, replace D1 with F1, D2 with F2, etc.
