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
AutoLock = Off means that the
internal trip will not 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) function is
done by activating the input BLOCK and can be used to block the output of
SMPPTRC in the event of internal failures.
11.1.3 Setting guidelines
The parameters for Tripping logic common 3-phase output SMPPTRC are set via the
local HMI or through the Protection and Control Manager (PCM600).
The following trip parameters can be set to regulate tripping.
