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 BE1-11t terminals D1 and D2 (A-phase).
Step 4: Using the values listed in Table 173, 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 the B-phase and C-phase current inputs. Note: Be sure
to enable proper target for each phase being tested.
Step 7: (Optional.) Repeat steps 1 through 6 for settings group 1, 2, and 3.
Step 8: (Optional.) Repeat steps 1 through 7 for 51-2, 51-3, 51-4, 51-5, 51-6, 51-7, 51-8, and 51-9.
Step 9: (Optional.) Repeat steps 1 through 8 with CT Circuit 2 as the source. In step 3, replace D1 with
F1, D2 with F2, etc.

Step 1: Use BESTCOMSPlus to send the operational settings in Table 174 to the BE1-11t. Reset all
targets.
