Step 7: Verify the pickup and dropout accuracy at 120 Vac for a pickup setting of 42 V (126 Vac on test
set) and 70 Vac for a pickup setting of 25 V (75 Vac on test set) as listed in Table 169. Record
the results.
Step 8: (Optional.) Repeat steps 1 through 7 for the B-phase and C-phase voltage inputs.
Step 9: (Optional.) Repeat steps 1 through 8 for settings group 1, 2, and 3.
Step 10: (Optional.) Repeat steps 1 through 9 for 59X-2, 59X-3, and 59X-4.
Timing Verification (V2 Mode)
Step 1: Use BESTCOMSPlus to open the Protection, Voltage, Overvoltage (59X-1) screen and send
the first row of test settings in Table 170 to the BE1-11g for settings group 0.
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 120 Vac, single-phase voltage source to terminals C13 (A-phase) and C16
(neutral).
Step 4: Step the voltage up to 130 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 170. 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 (Vx Fundamental Mode)
Step 1: Use BESTCOMSPlus to send the operational settings in Table 171 to the BE1-11g. Reset all
targets.
