Application manual
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.

Example of directional data

An example how to connect the directional data from different application
functions to the trip function is given below, see Figure 130:
