1. Check that AutoLock and TripLockout are both set to Off.
2. Initiate a three-phase fault
An adequate time interval between the faults should be considered, to
overcome a reclaim time caused by the possible activation of the autorecloser
(SMBRREC) function. The function must issue a three-phase trip in all cases,
when trip is initiated by any protection or some other built-in or external
function. The functional TRIP output signal must always appear.

Circuit breaker lockout

The following tests should be carried out when the built-in lockout function is used
in addition to possible other tests, which depends on the complete configuration of
a IED.
Procedure:
1. Check that AutoLock and TripLockout are both set to Off.
2. Initiate a three-phase fault
The functional output TRIP should be active at each fault. The output
CLLKOUT must not be set.
3. Activate the automatic lockout function, set AutoLock = On and repeat
Beside the TRIP outputs, CLLKOUT should be set.
4. Reset the lockout signal by shortly thereafter activating the reset lockout
(RSTLKOUT) signal.
5. Activate the TRIP signal lockout function, set TripLockout = On and repeat.
The output TRIP must be active and stay active after each fault, CLLKOUT
must be set.
6. Repeat.
All functional outputs should reset.
7. Deactivate the TRIP signal lockout function, set TripLockout = Off and the
automatic lockout function, set AutoLock = Off.

Completing the test

Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No, under Main menu/
Tests/Function test modes/<Function group>/<Function>/<1:Function> for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
