Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 183. Record the

results.

Step 6: (Optional.) Repeat steps 1 through 5 for the B-phase and C-phase current inputs.

Step 7: (Optional.) Repeat steps 1 through 6 for settings group 1, 2, and 3.

Step 8: (Optional.) Repeat steps 1 through 7 for 50-2, 50-3, 50-4, 50-5, and 50-6.

Step 9: (Optional.) Repeat steps 1 through 8 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.

Pickup Verification (3I0 Mode)

Step 1: Use BESTCOMSPlus to send the operational settings in Table 184 to the BE1-11g. Reset all

targets.

Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure 297.

• Blocking is disabled.

• OUT1 closes for 50-1 Trip.

• OUT2 closes for 50-1 Pickup.

• Fault recording is enabled.
