Frequency (81) Test BE1-11m
Step 3: Connect and apply a 120 Vac, 60-hertz voltage source to terminals C13 (A-phase) and C16
(neutral).
Step 4: Step the frequency of the applied voltage down to 55-hertz. Measure the time delay and record
the result.
Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delays listed in Table 61-5. Record the
results.
Step 6: (Optional.) Repeat steps 1 through 5 for settings groups 1, 2, and 3.
Step 7: (Optional.) Repeat steps 1 through 6 for 81-2, 81-3, and 81-4.
Pickup Verification (ROC Frequency)
Step 1: Use BESTCOMSPlus to send the operational settings in Table 61-6 to the BE1-11m. Reset all
targets.

Step 2: Use BESTCOMSPlus to configure the BESTlogicPlus programmable logic shown in Figure
61-3.
• Blocking is disabled.
• OUT1 closes for 81-1 Trip.
• OUT2 closes for 81-1 Pickup.
• Fault recording is enabled.

Step 3: Prepare to monitor the 81-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 61-3).
