1043 Man. Close CB Circuit breaker manual close - order received.
'If it is assigned to an opto input in the PSL and
energised the DDB:'Man Close CB' signal will enable the
internal 'SOTF Enable' logic without CB control
activation. If CB control is activated, SOTF will be
enabled by internal detection ('CB close' order managed
by CB control).
Manual closure of the circuit breaker will force the
autorecloser in a lockout logic, if selected in the
'Distance schemes / TOR-SOTF Mode') menu.
Any fault detected within 500 ms of a manual closure will
cause an instantaneous three pole tripping, without
autoreclose (see Block Autoreclose (BAR) logic)
When autoreclose lockout (BAR) is activated, the
autorecloser does not initiate any additional reclosing
cycle. If autoreclose lockout picks up during a cycle, the
A/R close is blocked.
This prevents excessive circuit breaker operations,
which could result in increased circuit breaker and
system damage, when closing onto a fault.
PSL (IN) CB
Status
1044 Man. Trip CB Circuit breaker manual trip - order received.
If it is assigned to an opto input in the PSL and
energised, the DDB:'Man Trip CB' signal will inform the
protection of an external CB trip command by the CB
control function (if activated).
PSL (IN) CB
Status
1045 CB Discrepancy CB Discrepancy (one pole open).
If it is assigned to an opto input in the PSL and
energised, the DDB:'CB Discrepancy' signal will inform
the protection of a pole discrepancy status (one pole
opened and the other two poles closed). It must be set
to high logical level before Dead time 1 has elapsed – it
can also be generated internally (see Cbaux logic).
PSL (IN) CB
Status
1046 External Trip A
Phase A trip by external protection relay. This input can
be used to update the CB condition monitoring.
Opto input is assigned to External Trip A (external Trip
command issued by main 2 or to initiate the internal A/R
backup protection). External trip is integrated in the
DDB: 'Any Trip'. As for an internal trip, no dwell timer is
associated to it.
PSL (IN)
1047 External Trip B
Phase B trip by external protection relay. This input can
be used to update the CB condition monitoring.
Opto input is assigned to External Trip B (external Trip
command issued by main 2 or to initiate the internal A/R
backup protection). External trip is integrated in the
DDB: 'Any Trip'. As for an internal trip, no dwell timer is
associated to it.
PSL (IN)
1048 External Trip C
Phase C trip by external protection relay. This input can
be used to update the CB condition monitoring.
Opto input is assigned to External Trip C (external Trip
command issued by main 2 or to initiate the internal A/R
backup protection). External trip is integrated in the
DDB: 'Any Trip'. As for an internal trip, no dwell timer is
associated to it.
PSL (IN)
1049 DIST. Chan Recv
Signal (carrier sent by zone) received on main channel
for distance scheme logic (depending on the ‘Distance
scheme’ setting: Program mode / Standard mode)

1050 DEF. Chan Recv
Signal received on main channel for DEF scheme logic
(depending on settings: Aided DEF/Scheme logic)
Selected as shared by default – Can operate as an
independent scheme with a separate opto input from
