Testing the gas medium supervision for temperature alarm and
temperature lock out conditions
1. 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.
2. Temperature lockout input SETTLO can be used to set TEMPLO signal.
3. Also, increase further the temperature input above TempLOLimit, check that
the outputs TEMPLO and LOCKOUT appears after a set time delay of
tTempLockOut.
4. Activate BLOCK binary input and check that the outputs TEMPALM, TEMPLO,
ALARM and LOCKOUT disappear.
5. Reset the BLOCK binary input.
6. Make sure that temperature lockout condition exists and then activate the
reset lock out input RESETLO and check that the outputs TEMPLO and
LOCKOUT reset.

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.

Liquid medium supervision SSIML

Prepare the IED for verification of settings as outlined in section
IED to verify settings" in this chapter.
Values of logical signals for SSIMG protection are available on the local HMI
under Main menu/Tests/Function status/Monitoring/InsulationLiquid(71)/
SSIML(71):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.
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. 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.
3. Liquid level lockout input SENLVLLO can be used to set LVLLO.
