1.
Check that AutoLock and TripLockout are both set to Off.
2.
Activate shortly the set lockout (SETLKOUT) signal in the IED.
3.
Check that the circuit breaker lockout (CLLKOUT) signal is set.
4.
Activate shortly thereafter, the reset lockout (RSTLKOUT) signal in the IED.
5.
Check that the circuit breaker lockout (CLLKOUT) signal is reset.
6.
Initiate a three-phase fault.
A three-phase trip should occur and all trip outputs TRL1, TRL2, TRL3 should
be activated. Functional outputs TRIP and TR3P should be active at each fault.
The output CLLKOUT should not be set.
7.
Activate the automatic lockout function, set AutoLock = On and repeat.
Besides the TRIP outputs, CLLKOUT should be set.
8.
Reset the lockout signal by activating the reset lockout (RSTLKOUT) signal.
9.
Activate the trip signal lockout function, set TripLockout = On and repeat.
All trip outputs (TRL1, TRL2, TRL3) and functional outputs TRIP and TR3P
must be active and stay active after each fault, CLLKOUT should be set.
10. Reset the lockout.
All functional outputs should reset.
11. 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 test by changing the TESTMODE setting
to Off. Restore connections and settings to their original values, if they were changed
for testing purposes.

in this chapter.
Check that the input logical signal BLOCK is logical zero and that on the local HMI,
the logical signals PRES_ALM, PRES_LO, TEMP_ALM and TEMP_LO are equal to
logical zero.
