11.1.2.2 Lock-out
This function block is provided with possibilities to initiate lock-out. The lock-out can be set to
only activate the block closing output CLLKOUT or initiate the block closing output and also
maintain the trip signal (latched trip).
The lock-out can then be manually reset after checking the primary fault by activating the input
reset Lock-Out RSTLKOUT or via the HMI.
If external conditions are required to initiate Lock-out but not initiate trip this can be achieved by
activating input SETLKOUT. The setting
activate lock-out so only initiation of the input SETLKOUT will result in lock-out. This is normally
the case for overhead line protection where most faults are transient. Unsuccessful autoreclose
and back-up zone tripping can in such cases be connected to initiate Lock-out by activating the
input SETLKOUT.
11.1.2.3 Blocking of the function block
Blocking can be initiated internally by logic, or by the operator using a communication channel.
Total blockage of Tripping logic (SMPPTRC ,94) function is done by activating the input BLOCK
and can be used to block the output of SMPPTRC (94) in the event of internal failures.
11.1.3 Setting guidelines
The parameters for Tripping logic common 3-phase output SMPPTRC (94) are set via the local HMI
or through the Protection and Control Manager (PCM600).
The following trip parameters can be set to regulate tripping.
Operation : Sets the mode of operation. Disabled switches the function off. The normal selection is
Enabled .
TripLockout : Sets the scheme for lock-out. Disabled only activates the lock-out output. Enabled
activates the lock-out output and latches the output TRIP. The normal selection is
AutoLock : Sets the scheme for lock-out. Disabled only activates lock-out through the input
SETLKOUT.
selection is
tTripMin : Sets the required minimum duration of the trip pulse. It should be set to ensure that the
breaker is tripped correctly. Normal setting is
