11.13.1.5 Circuit breaker lockout
SEMOD54375-170 v11
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 AutoLock and TripLockout are both set to Disabled.
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 AutoLock = Enabled 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 = Enabled and repeat.
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 TripLockout = Disabled and the automatic lockout
function, set AutoLock = Disabled.
11.13.1.6 Completing the test
SEMOD54375-203 v6
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
11.14 Monitoring
SEMOD53581-1 v1
11.14.1 Gas medium supervision SSIMG
GUID-0A83B4D5-51FF-43CB-8DC7-AFCEA2BC7B69 v5
Prepare the IED for verification of settings as outlined in Section
"Preparing the IED to verify settings" in
this chapter.
Values of logical signals for SSIMG protection are available on the local HMI under Main menu /Test /
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.
Using service kit. prepare the IED for verification of settings as outlined in Section
"Preparing the IED to
verify settings" in this chapter.
