Logic
This signal can also be used for other purposes internally in the IED. An example could be the
starting of breaker failure protection.
Set the required length of the trip pulse to for example, tTripMin = 150 ms.
For special applications such as lockout refer to the separate section below. The typical connection is
shown below in
Impedance protection zone 1 TRIP
Impedance protection zone 3 TRIP

14.1.3.2 Lock-out
The SMPPTRC function block is provided with possibilities to initiate lockout. The lockout can be set
to only activate the circuit breaker lockout output CLLKOUT or to both initiate the circuit breaker
lockout output and to maintain the trip signal output TRIP (latched).
If external conditions are required to initiate a circuit breaker lockout, it can be achieved by activating
input SETLKOUT. The setting AutoLock = Off means that the internal trip will not activate lockout so
only initiation of the input SETLKOUT will result in lockout. This is normally the case for overhead line
protection where most faults are transient. Unsuccessful autoreclosing and back-up zone tripping can
in such cases be connected to initiate lockout by activating the input SETLKOUT.
If CLLKOUT is set by an external trip signal from another protection function, that is by activating
SETLKOUT input, or internally by a trip, that is with the setting AutoLock = On and the setting
TripLockout=On, then also the trip output is set latched.
The lockout can manually be reset after checking the primary fault by activating the reset lockout
input RSTLKOUT. Note that the activation of the RSTLKOUT input will initiate a short pulse of 3 ms.
A new reset needs a new activation of the RSTLKOUT input.
