Step 9: Verify the BF time delay by applying pickup current (above 2 A) to phase A for at least 100 ms.
A 50BF Trip should occur. Use BESTCOMSPlus to retrieve an SER report and verify that a
50BF Trip was logged 100 milliseconds
±0.5% (1¼ cycles maximum for currents ≥ 5 times the
pickup setting. 1¾ cycles maximum for a current of 2 times pickup. Two cycles maximum for a
current of 1.05 times the pickup setting) after application of pickup current.
Step 10: (Optional.) Raise 50-1 Pickup setting to 10 amps and apply nominal current to the BE1-11g.
Note that OUT1 and OUT2 do not operate. No initiate prevents operation of the breaker failure
function, blocking the breaker fail logic.
Step 11: Verify the Control Time function by using BESTCOMSPlus to send the settings in Table 195 to
the BE1-11g.
Step 12: Connect a current source to terminals D1 and D2 (A-phase). Apply nominal current to the
BE1-11g and note operation of OUT3 and no operation of OUT1 and OUT2. To verify control
time, apply nominal current and start the test set timer. Use OUT3 to stop the timer. Record the
result.
