BE1-11m Auxiliary Overvoltage (59X) Test
Step 2: Prepare to monitor the 59X-1 timings. Timing accuracy is verified by measuring the elapsed
time between a sensing voltage change and OUT1 closing.
Step 3: Connect and apply a 150 Vac, three-phase voltage source to terminals C13 (A-phase), C14 (B-
phase), C15 (C-phase), and C16 (neutral).
Step 4: Step the A-phase voltage up to 215 volts. Measure the time delay and record the result.
Step 5: Repeat step 4 for the 5,000 ms and 10,000 ms time delay settings of Table 60-3. 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, 59X-3, and 59X-4.
Pickup Verification (V1 Mode)
Step 1: Use BESTCOMSPlus to send the operational settings in Table 60-4 to the BE1-11m. Reset all
targets.

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

Step 3: Use BESTCOMSPlus to open the Protection, Voltage, Overvoltage (59X-1) screen and send
the first row of test settings in Table 60-5 to the BE1-11m.
