10.10.2.2
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.
6.
Activate BLOCK binary input and check that the outputs LVLALM, LVLLO, ALARM and
LOCKOUT disappears.
7.
Reset the BLOCK binary input.
8.
Ensure that level lockout condition exists and then activate the reset lockout input RESETLO
and check that the outputs PRESLO and LOCKOUT reset.
10.10.2.3
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.
10.10.2.4
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.
10.10.3
Breaker monitoring SSCBR
Prepare the IED for verification of settings outlined in section "Testing the IED operation".
The Signal Monitoring tool in PCM600 shows the service values that are available on the Local HMI
as well.
Values of the logical signals belong to the breaker monitoring are available on the local HMI under:
