Phase loss alarm

The phase loss alarm is an under setpoint alarm that monitors the voltages on a 3-phase system and triggers the alarm when one or two phases fall below the pickup setpoint setting and remain there long enough to satisfy the pickup time delay period.

When all of the phases rise above the dropout setpoint setting and remain there long enough to satisfy the dropout time delay period, the alarm condition is set to OFF.
