Step 4: Prepare to monitor the 50-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 255).
Step 5: Connect a current source to terminals D1 and D2 (A-phase).
Step 6: Slowly increase the A-phase current until OUT2 closes and record the pickup. Verify that there
is a 50-1-Residual 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 (3I0 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 160 to the BE1-11t for settings group 0.
Table 160. Timing Test Settings (3I0 Mode)
Pickup Setting Time Delay
0.5 A 2,000 ms
0.5 A 5,000 ms
0.5 A 10,000 ms
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 D1 and D2 (A-phase).
