9.8.1.2
Testing the gas medium supervision for temperature alarm and
temperature lock out conditions
GUID-EC145626-90B0-45A2-AD58-CB8BF203FE16 v1
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.
9.8.1.3
Completing the test
GUID-DD08C598-A35C-4300-9555-A0877F7DC511 v2
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.
9.8.2
Liquid medium supervision SSIML
GUID-6426FDDA-B949-4FE7-BF42-B52014A9344B v4
Prepare the IED for verification of settings as outlined in section
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.
9.8.2.1
Testing the liquid medium supervision for level alarm and level lockout
conditions
GUID-C1F1E6CA-9512-4358-A4E7-84CC3698D156 v3
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
.
4.
Also, 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.
5.
Activate
BLOCK
binary input and check that the outputs
LVLALM
,
LVLLO
,
ALARM
and
LOCKOUT
disappears.
6.
Reset the
BLOCK
binary input.
7.
Make sure that level lockout condition exists and then activate the reset lock out input
RESETLO
and check that the outputs
PRESLO
and
LOCKOUT
reset.
