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 BE1-11t.
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 169 to
the BE1-11t.
