Fault Words:
"Phase a Loss"
(There is no voltage sensed on 3-L1/S)
"Voltage Low"
(Average line voltage is less than selected Undervoltage Percentage)
"Voltage High"
(Average line voltage is more than selected Overvoltage Percentage)
"Imbalance"
(One phase is lower than the average voltage by more than the Imbalance
percentage)
"Phase Loss
(One phase is more than 30% below the Line Voltage selection)
"Bad Rotation"
(The phase rotation sequence is reversed)
"Bad Freq"
(Line frequency out of allowable range of 45 to 65 Hz)
