9.7.1.2 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.
9.7.1.3 Completing the test
GUID-DD08C598-A35C-4300-9555-A0877F7DC511 v1
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.
9.7.2 Liquid medium supervision SSIML
GUID-6426FDDA-B949-4FE7-BF42-B52014A9344B v3
Prepare the IED for verification of settings as outlined in section "Preparing the
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.
9.7.2.1 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
.
