The monitoring module will raise an alarm when the
AC voltage of an operating route is lower than the
80V "UnderVolt", but there will be no alarm when the AC
voltage of the standby route is lower than the
"UnderVolt"
Set this parameter according to the actual situation. In a system with an AC sampling
3-phase board, you can only select "Single Phase" or "3-phase"; in a system without an AC
sampling board, you can select only "None"
The "UnderVolt" must be lower
than the "LowVolt"
