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.
10.12.1.4 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.
10.12.2 Liquid medium supervision SSIML
Prepare the IED for verification of settings as outlined in section
settings"" in this chapter.
Values of logical signals for SSIML protection are available on the local HMI under Main menu /
Test /Function status /Monitoring /InsulationLiquid /SSIML:x , where x = 1, 2,....4.
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the logical signals
LVLALM, LVLLO, TEMPALM, TEMPLO, ALARM and LOCKOUT are logical zero.

10.12.2.2 Testing the liquid medium supervision for level alarm and level lockout
conditions
1. Connect the binary inputs to consider liquid level to initiate the alarms.
2. Activate the binary input SENLEVELQ.
3. Consider the analogue level input SENLEVEL and set SENLEVEL to a value lower than
LevelAlmLimit or activate binary input signal SENLVLALM, check that outputs LVLALM and
ALARM are activated after a set time delay of tLevelAlarm.
4. Liquid level lockout input SENLVLLO can be used to set LVLLO.
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.

2.2.4 Binary quality inputs SENLVLQ and SENTEMPQ have been added for pressure and
temperature sensor signals in order to control alarm and lockout signals. Whenever there
is no sensor, the quality of the binary input will be low. If sensor quality is low, then
lockout and alarm signals will get reset.
