Phase to balance (1 alarm; 1 trip) monitors the symmetry of voltage between phases. To be used for imbalance < 40 % of the average voltage.
Phase failure (1 alarm; 1 trip) monitors the symmetry of voltage between phases. To be used for imbalance > 40 % of the average voltage.
Phase reversal (1 trip) signals when the phase sequence is different from the defied sequence (motor stopped).
Voltage variation (1 alarm; 1 trip) Min/max voltage limits; monitors voltage variations around preset thresholds.
Load shedding; opens outputs O.1 and O.2 if voltage drops below a preset threshold.
Power variation (1 alarm; 1 trip) Min/max power limits; monitors power variations around preset thresholds.
Variations of Cos phi (1 alarm; 1 trip) Min/max limits of Cos phi; monitors variations of Cos phi around preset thresholds.
