Section 9
Testing functionality by secondary injection
5.
Ensure that binary input SENLEVELQ is activated and reduce the liquid level input below
LevelLOLimit or activate the binary input signal SENLVLLO, check that LVLLO signal after a set
time delay of tLevelLockOut.
6.
Activate BLOCK binary input and check that the outputs LVLALM, LVLLO, ALARM and
LOCKOUT disappears.
7.
Reset the BLOCK binary input.
8.
Ensure that level lockout condition exists and then activate the reset lockout input RESETLO
and check that the outputs PRESLO and LOCKOUT reset.
9.5.2.2
Testing the gas medium supervision for temperature alarm and
temperature lockout conditions
1.
Activate the binary input SENTEMPQ.
2.
Consider the analogue temperature input SENTEMP and set SENTEMP to a value higher than
TempAlarmLimit, check that outputs TEMPALM and ALARM are activated after a set time delay
of tTempAlarm.
3.
Temperature lockout input SETTLO can be used to set TEMPLO signal.
4.
Ensure that binary input SENTEMPQ is activated and increase further the temperature input
above TempLOLimit, check that the outputs TEMPLO and LOCKOUT appear after a set time
delay of tTempLockOut.
5.
Activate BLOCK binary input and check that the outputs TEMPALM, TEMPLO, ALARM and
LOCKOUT disappear.
6.
Reset the BLOCK binary input.
7.
Ensure that temperature lockout condition exists and then activate the reset lockout input
RESETLO and check that the outputs TEMPLO and LOCKOUT reset.
9.5.2.3
Completing the test
Using the LHMI service kit, 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.
9.5.3
Breaker monitoring SSCBR
Using the LHMI service kit, prepare the IED for verification of settings outlined in section "Testing the
IED operation".
The Signal Monitoring tool in PCM600 shows the service values.
9.5.3.1
Verifying the settings
1.
Connect the test set for the injection of a three-phase current to the appropriate current
terminals of the IED.
2.
If current need to be injected for a particular test, it should be done in the phase selected by the
PhSel parameter.
3.
Follow the sequence for positioning the auxiliary contacts before testing:
POSCLS
POSOPN
4.
Test of CB contact operation time
