local time. As no reboot is necessary, the time synchronization starts immediatelyafter the IRIG-B sync source is selected and the IRIG-B signal source is connected.ABB has tested the IRIG-B with the following clock masters:• Tekron TTM01 GPS clock with IRIG-B output• Meinberg TCG511 controlled by GPS167• Datum ET6000L• Arbiter Systems 1088BIRIG-B time synchronization requires a COM card with an IRIG-Binput.When using line differential communication between RED615 IEDs, the timesynchronization messages can be received from the other line end IED within theprotection telegrams. The IED begins to synchronize its real-time clock with theremote end IEDs time if the Line differential time synchronization source isselected. This does not affect the protection synchronization used in the linedifferential protection or the selection of the remote end IEDs time synchronizationmethod.

Each setting group contains parameterscategorized as group settings inside application functions. The customer canchange the active setting group at run time.The active setting group can be changed by a parameter or via binary inputsdepending on the mode selected with the Configuration/Setting Group/SGoperation mode setting.[1] The line differential protection is available only in RED615.1YHT530004D05 D Section 3Basic functions615 series 71Technical Manual
