Output Test (25A Voltage Monitor)
Step 1: With no voltage applied to either the Line or Auxiliary voltage sources, OUT7 should be closed.
This verifies the DEAD-LINE, DEAD AUX output of 25 Voltage Monitor.
Step 2: Increase the Line VTP voltage above the DEAD-LINE setting and verify that OUT7 opens.
Continue increasing voltage until OUT7 closes when the LIVE-LINE setting is exceeded. This
verifies the LIVE-LINE, DEAD-AUX output of 25A Voltage Monitor. Remove voltage source 1.
Step 3: Increase the Auxiliary VTX voltage above the DEAD-LINE setting and verify that OUT7 opens.
Continue increasing voltage until OUT7 closes when the LIVE-LINE setting is exceeded. This
verifies the DEAD-LINE, LIVE-AUX output of 25A Voltage Monitor.
Step 4: (Optional.) Repeat Steps 1 through 3 for Settings Group 1, 2, and 3.
