Current Differential Relay

Output - Out of Service
Setting this to “Yes” will allow the Logic Bus signals representing the out of service flag output bit to
trigger a SOE recording. A change of state of the bit will initiate an SOE recording. The relay may be
out of service if it has been disabled by the user, is in the process of initializing, or has taken itself out
of service due to a detected problem.
Output - Phase Loss
Setting this to “Yes” will allow the Logic Bus signals representing the phase loss output bit to trigger a
SOE recording. A change of state of the bit will initiate an SOE recording.
Output – DTT from Remote 1
Setting this to “Yes” will allow the logic bus signal representing the DTT from remote terminal 1 to
trigger an SOE recording. A change of state of the DTT from remote 1 output will also initiate an SOE
recording.
Output – DTT from Remote 2
Setting this to “Yes” will allow the logic bus signal representing the DTT from remote terminal 2 to
trigger an SOE recording. A change of state of the DTT from remote 2 output will also initiate an SOE
recording.
Output - Transferred Status # 0 through #7
Setting this to “Yes” will allow the Logic Bus signals representing the Rx Transferred Status output
bits to trigger a SOE recording. A change of state of the logic bus bit will initiate an SOE recording.
Note that these bits are outputs from the relay, the relay has received the information from the remote
relay (hence “Rx” bits).
See section 13.5.2.7 for more information.
