Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.
Step 9: (Optional.) Repeat steps 1 through 8 for 50-2, 50-3, 50-4, 50-5, and 50-6.
Step 10: (Optional.) Repeat steps 1 through 9 with CT Circuit 2 as the source for protection systems
equipped with two sets of CTs. In step 5, replace D1 with F1, D2 with F2, etc.
Timing Verification (IG Mode)
Step 1: Use BESTCOMSPlus to open the Protection, Current, Instantaneous Overcurrent (50-1) screen
and send the first row of test settings in Table 142 to the BE1-11m for settings group 0.

Step 2: Prepare to monitor the 50-1 timings. Timing accuracy is verified by measuring the elapsed time
between a sensing current change and OUT1 closing.
Step 3: Connect and apply 0.45 A to BE1-11m terminals D7 and D8 (IG).
Step 4: Step the ground current up to 0.55 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 142. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 50-2, 50-3, 50-4, 50-5, and 50-6.
Step 8: (Optional.) Repeat steps 1 through 7 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.
Functional Test Report
Pickup Verification (Phase Mode)
Pickup Setting Range = 0.5 to 150 A for 5A sensing
0.1 to 30 A for 1A sensing
Pickup Accuracy =
±2% or ±50 mA, whichever is greater for 5A sensing
±2% or ±10 mA, whichever is greater for 1A sensing
Dropout should occur between 93-99% of the actual pickup value.
