| Working | 1] If the Input supply is within the range of the fault limits then On Timer starts decrementing on display & after Set On Time over Relay will be ON; 2] If OV, UV occurs in the supply then Relay will be OFF after the trip delay of that particular fault.; 3] IF R ,Y ,B all phase are present than relay on condition. Controller select any one of the phase to the R, Y, B. In case of R phase are absent. Controller select Y phase. Same as another two phase work as same.; 4] If any two phases are abse |
