DDB no. English text Source Description
1377 O/C Trip By VTS
This applies only if distance primary FUN is
selected (in IEC870-5-103)
This signal is ON if DDB 1376 is ON and one
of the overcurrent stages set to be enabled on
VTS condition trips
1378 Teleprot Tx
This applies only if distance primary FUN is
selected (in IEC870-5-103)
This is an output signal available in the PSL,
which could be mapped to a signal send of
one of the two teleprotection channels
1379 Teleprot Rx
This applies only if distance primary FUN is
selected (in IEC870-5-103)
This is an output signal available in the PSL,
which could be mapped to a signal receive of
one of the two teleprotection channels
1380 Group Warning
This is an output signal available in the PSL,
which can be mapped in IEC870-5-103 to a
minor defect which does not shut down the
main protection
1381 Group Alarm
This is an output signal available in the PSL,
which can be mapped in IEC870-5-103 to a
major problem normally linked to the watchdog
1382 AR On Pulse
This is an output signal available in the PSL,
which can be mapped to enable AR via pulse
1383 AR OFF Pulse
This is an output signal available in the PSL,
which can be mapped to disable AR via pulse
1384 AR Enable
This is an output signal available in the PSL,
which can be mapped to enable AR
1385 AR In Service Auto-reclose in service
1386 MaxCh1 PropDelay

1404 VTS Blk Distance VTS Logic
Signal from the VTS logic that can be used to
block operation of the distance elements

1408 CB2 Lead Auto-reclose
If setting "Leader Select By:" = Opto, then
preferred leader CB is CB1 if input DDB "CB2
LEAD" is low, or CB2 if DDB "CB2 LEAD" is
high.
P544 and P546 only
1409 Follower AR 1P Auto-reclose
If setting "Foll AR Mode" = Opto, then if input
DDB "FARSP" is high, the follower CB is
enabled for single phase autoreclose, if
"FARSP" is low, the follower CB is NOT
enabled for single phase autoreclose.D2215
P544 and P546 only
