When SG1/6 = 0, the undervoltage stage always operates when a measured voltage falls below the setting value. When SG1/6 = 1, starting and tripping of the undervoltage stage are blocked if one of the measured voltages, falls to a value below 0.2 x U This feature can be used for preventing unnecessary startings and trippings during auto-reclose sequences.
