protection scheme.
7. Check, that the output signals, issued for the first fault, correspond to a two-phase trip for
included phases. The output signals generated by the second fault must correspond to the
three-phase tripping action.
11.12.1.4 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 an IED.
1. Check that
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- trip should occur and all trip outputs TR_A, TR_B, TR_C 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
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
All trip outputs (TR_A, TR_B, TR_C) 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

Restore connections and settings to their original values, if they were changed for testing
purposes.

Prepare the IED for verification of settings as outlined in Section
settings"
Values of logical signals for SSIMG protection are available on the local HMI under Main menu/
Tests/Function status/Monitoring/InsulationGas(63)/SSIMG(63):x, where x = 1, 2,....21.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the logical
signals PRESALM, PRESLO, TEMPALM, TEMPLO, ALARM and LOCKOUT are logical zero.
