Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 60-12. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings group 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 59X-2.
Pickup Verification (Vx Third Harmonic Mode)
Step 1: Use BESTCOMSPlus to send the operational settings in Table 60-13 to the BE1-11m. Reset all
targets.

Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure
60-5.
• Blocking is disabled.
• OUT1 closes for 59X-1 Trip.
• OUT2 closes for 59X-1 Pickup.
• Fault recording is enabled.
