Step 8: (Optional.) Repeat steps 1 through 7 for settings group 1, 2, and 3.
Step 9: (Optional.) Repeat steps 1 through 8 for 51-2, 51-3, 51-4, and 51-5.
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 (3I0 Mode)
Step 1: Use BESTCOMSPlus to open the Protection, Current, Inverse Overcurrent (51-1) screen and
send the test settings in Table 152 to the BE1-11m for settings group 0.

Step 2: Prepare to monitor the 51-1 timings. Timing accuracy is verified by measuring the elapsed time
between a sensing current change and OUT1 closing.
Step 3: Connect a current source to BE1-11m terminals D1 and D2 (A-phase).
Step 4: Using the values listed in Table 153, apply the appropriate current values, and measure the
time between the application of current and the closure of OUT1. Record the results.
Step 5: Repeat step 4 for all of the current and time dial settings for your current sensing type.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 51-2, 51-3, 51-4, and 51-5.
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.
