Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure 317.
•
Blocking is disabled.
•
OUT1 closes for 51-1 Trip.
•
OUT2 closes for 51-1 Pickup.
•
Fault recording is enabled.
Step 3: Use BESTCOMSPlus to open the Protection, Current, Inverse Overcurrent (51-1) screen and
send the low range test settings (minimum pickup setting) to the BE1-11g for your sensing input
type in Table 206.

Step 4: Prepare to monitor the 51-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 317).
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 51-1-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 51-2, 51-3, 51-4, 51-5, 51-6, and 51-7.
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.
