Ordinal English Text Description Source
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 500ms 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
1055 MCB/VTS Main
Fuse failure on line VT or MCB open (blocks voltage
dependant functions). If it is linked to an opto input in
the PSL energised, the DDB informs the P44x about
an internal maloperation from the VT used for the
impedance measurement reference (line in this case
means Main VT ref measurement, even if the main VT
is on the bus side and the Synchronism check VT is on
the line side).
PSL (IN) VTS
1054 MCB/VTS Synchro
Fuse failure on busbar VT or MCB open (blocks
voltage dependant functions), If it is linked to an opto
input in the PSL and energised, the DDB signal informs
the P44x about an internal maloperation from the VT
used for synchronisation check (see Check
Synchronism logic section).
PSL (IN) VTS
204 NCIT Alarm
Relays with IEC 61850 9-2 Ethernet board only
(software version D5.x)
IEC 61850 9-2 Alarm - Frame from Merge Units
missing. If two consecutive of any Logical Node frames
have not been received within the Merge Unit Delay
set parameter (time of silence in the reception of the
frame), the LN is “absent”
