The device continuously monitors its three-phase power supply and provides a visual indication of the status of each connected phase and whether the phase sequence is correct. If any phase is lost, the corresponding phase indicator LED turns off, and the status LED changes from green (“Correct”) to red (“Incorrect”). In the event of a reversed-phase sequence, the status LED alone changes from green to red, indicating an incorrect sequence while the phase LEDs remain lit.
