DATAKOMDKG-705 User’s ManualDefinition Source DescriptionParallel Mains Fail Internal This general warning is set if any of the protection functions havedetected a mains failure during parallel with mains operation.Mains Reverse Power Internal In parallel with mains operation and after the parallel checktimeout delay (P_A23) has elapsed, this warning will be set if themains power is negative and over the reverse power limit defined inP_A24.Mains Frequency Fail R In parallel with mains operation and after the parallel check timeoutdelay (P_A23) has elapsed, this warning will be set if the mainsfrequency is out of the limits defined in P_522 and P_523 for 4consecutive cycles.No Mains Frequency R In parallel with mains operation and after the parallel check timeoutdelay (P_A23) has elapsed, this warning will be set if the mainsfrequency disappears for more than 2,5 periods.ROCOF (df/dt) Fail R In parallel with mains operation and after the parallel check timeoutdelay (P_A23) has elapsed, this warning will be set if the mainsfrequency change exceeds the limit defined in P_A25 for 4consecutive cycles.Vector Shift (df/dt) Fail R In parallel with mains operation and after the parallel check timeoutdelay (P_A23) has elapsed, this warning will be set if the phase ofthe mains measured on last 2 cycles jumps over the limit definedin P_A26 on the phase measured on last 4 th and 5 th period.Communication Lost(dual genset mode)SerialComm.Set if the serial communication between Master and Slave gensetsis interrupted and Single Genset Load Enable parameter (P_A32)is set to 1.705-UE.doc - 17 -
