11.11.1.2 Testing the gas medium supervision for pressure alarm and pressure lockout
conditions
1. Connect the binary inputs to consider gas pressure and gas density to initiate the alarms.
2. Activate the binary input SENPRESQ.
3. Consider the analogue pressure input SENPRES and set SENPRES to a value lower than
PresAlmLimit or activate binary input signal SENPRESALM, check that outputs PRESALM and
ALARM are activated after a set time delay of tPressureAlarm .
4. Gas pressure lockout input SETPLO can be used to set PRESLO.
5. Ensure that binary input SENPRESQ is activated and reduce further the pressure level input below
PresLOLimit or activate the binary input signal SENPRESLO, check that PRESLO signal appears
after a set time delay of tPressureLO .
6. Activate BLOCK binary input and check that the outputs PRESALM, PRESLO, ALARM and
LOCKOUT disappears.
7. Reset the BLOCK binary input.
8. Ensure that pressure lockout condition exists and then activate the reset lockout input RESETLO
and check that the outputs PRESLO and LOCKOUT reset.
11.11.1.3 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.
11.11.1.4

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.
11.11.2

Liquid medium supervision SSIML

Prepare the IED for verification of settings as outlined in section
this chapter.
Values of logical signals for SSIML protection are available on the local HMI under Main menu /Test /
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.
