Step 4:
Prepare to monitor the 59X-1 function operation. Operation can be verified by monitoring OUT2
(see Figure 301).
Step 5:
Connect and apply a 240 Vac, single-phase voltage source to terminals C13 (A-phase) and C16
(neutral). For a single-phase input test, V1 = A-phase voltage / 3. Therefore, the BE1-11g
should pick up at a value of three times the setting value when applying only a single-phase
input. For example, to determine the pickup voltage value required for a BE1-11g with a pickup
setting of 82, it would require 82 times 3 or 246 volts of input voltage.
Step 6:
Slowly increase the voltage until OUT2 closes and record the pickup. Verify that there is a 59X-
1-V1 target on the front-panel display. Slowly decrease the voltage until OUT2 opens and
record the dropout. Reset the target.
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 166. 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 (V1 Mode)
Step 1:
Use BESTCOMSPlus to open the Protection, Voltage, Overvoltage (59X-1) screen and send
the first row of test settings in Table 167 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 167. 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 (V2 Mode)
Step 1:
Use BESTCOMSPlus to send the operational settings in Table 168 to the BE1-11g. Reset all
targets.
