Step 3: Use BESTCOMSPlus to open the Protection, Current, Instantaneous Undercurrent (37) screen
and send the low range test settings (minimum pickup setting) to the BE1-11m for your sensing
input type in Table 129.
Table 129. Pickup Test Settings
Sensing Input Type Range Pickup Setting Time Delay
5 A
Low 0.5 A 0 ms
Middle 5.0 A 0 ms
High 20.0 A 0 ms
1 A
Low 0.1 A 0 ms
Middle 1.0 A 0 ms
High 4.0 A 0 ms
Step 4: Prepare to monitor the 37 function operation. Operation can be verified by monitoring OUT2
(see Figure 252).
Step 5: Connect a current source and apply 0.6 Aac to terminals D1 and D2 (A-phase). Note that IA, IB,
or IC can be used for this test. Test is conducted on IA.
Step 6: Slowly decrease the A-phase current until OUT2 closes and record pickup. Verify the 37-1
target on the front-panel display. Slowly increase the applied current until OUT2 opens and
record reset.
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 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.
