Step 4: Prepare to monitor the 25VM function operation. Operation can be verified by monitoring OUT7.
Step 5: Connect BE1-11g terminals C13 (A-phase), C14 (B-phase), and C15 (C-phase) together. Apply
a single-phase, 0 Vac, 50- or 60-hertz ac voltage source (Line VTP) to the three jumpered
terminals and the neutral terminal (C16). OUT7 should be closed.
Step 6: Slowly increase the line voltage until OUT7 opens (55 volts). Record the result.
Step 7: Increase the voltage until OUT7 closes (90 volts). Record the result.
Step 8: Remove voltage source 1. Connect a second single-phase, 50- or 60-hertz voltage source
(Auxiliary VTX) to BE1-11g terminals C17 (polarity) and C18 (non-polarity). Apply 0 Vac. OUT7
should be closed.
Step 9: Slowly increase the Auxiliary voltage until OUT7 opens (55 V). Record the result.
Step 10: Increase the voltage until OUT7 closes (90 volts). Record the result.
Step 11: (Optional.) Repeat Steps 3 through 10 for Settings Group 1, 2, and 3.
Live/Dead Dropout Timing Verification (25A Voltage Monitor)
Step 1: Use BESTCOMSPlus to open the Control, Synchronizer (25A) screen and send the first row of
test settings in Table 239 to the BE1-11g.

90% 55% 50 ms Check boxes as shown
in Table 237.
90% 55% 2,000 ms Check boxes as shown
in Figure 318.
90% 55% 5,000 ms Check boxes as shown
in Figure 318.
Step 2: Prepare to monitor the 25A Voltage Monitor Live/Dead timing. Timing accuracy is verified by
measuring the elapsed time between a sensing voltage change and OUT7 opening.
Step 3: Connect BE1-11g terminals C13 (A-phase), C14 (B-phase), and C15 (C-phase) together. Apply
a 50 Vac, 50 or 60 Hz source (Line VTP) to the three jumpered terminals and the neutral
terminal (C16).
Step 4: Step the voltage up to 60 V. Measure the time delay and verify the accuracy of the dead
dropout time delay setting. Record the result.
Step 5: Set the ac voltage at 95 V. Step the voltage down to 85 V. Measure the time delay and verify
the accuracy of the Live dropout delay setting. Record the result.
Step 6: Repeat Steps 5 and 6 for the middle and upper time delay settings of Table 239.
Step 7: Remove phase voltage (Line VTP) and connect a second single-phase 50- or 60-hertz voltage
source (Auxiliary VTX) to BE1-11g terminals C17 (polarity) and C18 (non-polarity). Repeat
Steps 4 through 6.
Step 8: (Optional.) Repeat Steps 2 through 7 for Settings Group 1, 2, and 3.
