8-26 Application BE1-CDS220
State Labels
Output Purpose Description Label
True False
VO1
Transformer fault trip (86T for
example).
OUT1 contact closes if a
restrained, unrestrained, or
phase differential is TRUE.
TRIP_86T-O TRIP NORMAL
BESTlogic Expression: VO1=87RT+87UT+51NT+151PT+151NT+151QT
VO2
Transformer fault trip (86B for
example).
Trip bus breaker via lockout for
bus faults (250T w/ 18-20 cycles
delay).
TRIP-86B-O TRUE FALSE
BESTlogic Expression: VO2=250TQT
VO3
Breaker 2 breaker failure trip.
(86F for example)
TRUE when BFT or 62 times out TRIP-86F-O TRUE FALSE
BESTlogic Expression: VO3=BFT+62
VO4 Breaker 2 trip.
Trip if 87R or 87U trip output of
the phase diff. protection
function is TRUE. Or for 251
bus backup over-current trip. Or
for control switch trip. Or when
BF is initiated.
TRIP-BKR2- TRIP NORMAL
BESTlogic Expression: VO4=87RT+87UT+251PT+251NT+251QT+VO9+BFPU+101T
VO5 Breaker 2 close.
Close breaker if virtual control
switch is TRUE and 86T or 86B
LO is not tripped.
CLOSE-BKR2 CLOSE NORMAL
BESTlogic Expression: VO5=101C*/IN3*/IN4
VO6
Signal relay on bus source
that is using BUS logic that a
feeder relay is out of service. Feeder relay is out of service as
indicated by contact open from
the feeder relays.
FDR-BACKUP BACKUP NORMAL
BESTlogic Expression: VO6=/IN5
VO9
52b supervised breaker
failure initiate expression
Initiate BF timing (62 timer)
when 87R or 87U trip is TRUE
or when external BFI contact
(IN6) is sensed. Stop BF timing
when breaker opens (52a status
contact). Prevent initiate when
in test mode (VO15).
BFI-62 INI NORMAL
BESTlogic Expression: VO9=87RT*IN2*/VO15+87UT*IN2*/VO15+IN6*IN2*/VO15
VO10
Current supervised breaker
failure initiate expression.
Initiate BF timing when
protective trip expression is
TRUE. Or when external initiate
contact (IN7) is sensed and any
of the fault detectors is picked
up.
BFI-BF INI NORMAL
BESTlogic Expression: VO10= VO11+IN7*IN7*IN7*150TQPU
