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.
9.11.2.2 Testing the liquid medium supervision for temperature alarm and
temperature lock out conditions
GUID-189AF20B-D0E3-453D-A787-68F25D0903D3 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.
9.11.2.3 Completing the test
GUID-1A0D8AF0-4C48-45E8-B31D-96734ED1A4D2 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.
9.11.3 Breaker monitoring SSCBR
GUID-10D26C82-79FF-4EAD-AE4A-2F2DBE965087 v2
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: Main menu/Test/Function status/Monitoring/
