The lock-out can then be manually reset after checking the primary fault by
activating the input reset lock-out RSTLKOUT.
If external conditions are required to initiate a closing circuit lock-out but not to
lockout 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.
