Step 10: Increase the voltage until OUT2 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 (25 Voltage Monitor)
Step 1: Use BESTCOMSPlus to open the Protection/Voltage/Sync-Check (25) screen and send the first
row of test settings in Table 134 to the BE1-11g.

Step 2: Prepare to monitor the 25 Voltage Monitor Live/Dead timing. Timing accuracy is verified by
measuring the elapsed time between a sensing voltage change and OUT2 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-hertz ac voltage source (Line VTP) to the three jumpered terminals and the
neutral terminal (C16).
Step 4: Step the voltage up to 60 volts. 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 volts. Step the voltage down to 85 volts. 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 134.
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.
Output Test (25 Voltage Monitor)
Step 1: With no voltage applied to either the Line or Auxiliary voltage sources, OUT2 should be closed.
This verifies the DEAD-LINE, DEAD AUX output of 25 Voltage Monitor.
Step 2: Slowly raise the volts ac to the line voltage input (VTP). Output 2 will open as the voltage is
increased above the DEAD-LINE setting and close again when voltage exceeds the LIVE-LINE
setting. This verifies the LIVE-LINE, DEAD-AUX output of 25VM. Remove voltage source 1.
Step 3: Slowly raise the volts ac to the auxiliary voltage input (VTX). Output 2 will open as the voltage is
increased above the DEAD-LINE setting and close again when voltage exceeds the LIVE-LINE
setting. This verifies the DEAD-LINE, LIVE-AUX output of 25 Voltage Monitor. Remove voltage
source 2.
Step 4: (Optional.) Repeat steps 1 through 3 for settings group 1, 2, and 3.
Sync-Check Verification (25)
Step 1: Use BESTCOMSPlus to open the Protection/Voltage/Sync-Check (25) screen and send the test
settings in Table 135 to the BE1-11g.
