Step 6: Slowly increase the ground current until OUT2 closes and record the pickup. Verify that there is
a 50-1-IND GND target on the front-panel display. Slowly decrease the applied current until
OUT2 opens and record the dropout.
Step 7: Repeat step 6 for the middle and high range pickup settings for your sensing input type. Record
the results.
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, 50-6, 50-7, 50-8, and 50-9.
Step 10: (Optional.) Repeat steps 1 through 9 with CT Circuit 2 as the source. 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 166 to the BE1-11t 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 BE1-11t 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 166. 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, 50-6, 50-7, 50-8, and 50-9.
Step 8: (Optional.) Repeat steps 1 through 7 with CT Circuit 2 as the source. 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.
