1051 DIST. COS
Distance scheme channel out of service / Loss of Guard
(Carrier out of service)
PSL (IN) Un-
blocking logic
1052 DEF. COS
DEF scheme channel out of service / Loss of Guard
Selected shared by default – Can operate as an
independent scheme with a different opto input from Dist
Default PSL: Opto Label 2
PSL (IN) Un-
blocking logic
1053 Z1X Extension
Zone 1 Extension Input
Opto input energized if linked by PSL OR any internal
DDB by dedicated PSL
At 1: Signal will initiate Z1 extension logic if selected
(setting).
This DDB can be assigned to any external/Internal
condition for starting Z1X logic
PSL (IN)
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
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).

1056 IN>1 Timer Block
Block earth fault stage 1 time delay
Set to 1: 'IN>1 Time Delay' will be blocked & IN>1 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN)
Earth Fault
1057 IN>2 Timer Block
Block earth fault stage 2 time delay
Set to 1: 'IN>2 Time Delay' will be blocked & IN>2 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN)
Earth Fault
1058 IN>3 Timer Block
Block earth fault stage 3 time delay
Set to 1: 'IN>3 Time Delay' will be blocked & IN>3 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN)
Earth Fault
1059 IN>4 Timer Block
Block earth fault stage 4 time delay
Set to 1: The IN>4 time-delay will be blocked & IN>4 will
start but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN)
Earth Fault
1060 DEF Timer Block
Block aided DEF time delay
The DEF time-delay will be blocked & DEF will start but
will not issue any trip command.
Reset to 0: Opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN) DEF
1061 I>1 Timer Block
Block phase overcurrent stage 1 time delay
Set to 1: 'I>1 Time Delay' will be blocked & I>1 will start
but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN) I>1
1062 I>2 Timer Block
Block phase overcurrent stage 2 time delay
Set to 1: 'I>2 Time Delay' will be blocked & I>2 will start
but will not issue any trip command.
Reset to 0: opto input power off if signal assigned to an
opto input OR DDB at 0 if signal assigned to a DDB cell
PSL (IN) I>2
