11.12.2.1 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. 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
3. Liquid level lockout input SENLVLLO can be used to set LVLLO.
4. Also, reduce the liquid level input below
SENLVLLO, check that LVLLO signal after a set time delay of
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.
11.12.2.2 Testing the liquid medium supervision for temperature alarm and
temperature lock out conditions
1. Consider the analogue temperature input SENTEMP and set SENTEMP to a value higher
than
time delay of
2. Temperature lockout input SETTLO can be used to set TEMPLO signal.
3. Also, increase further the temperature input above
TEMPLO and LOCKOUT appears after a set time delay of
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.
11.12.2.3

Completing the test

Continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.

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: Main menu/Test/Function status/Monitoring/BreakerMonitoring/SSCBR:x
11.12.3.1

Verifying the settings

1. Connect the test set for the injection of a three-phase current to the appropriate current
terminals of the IED.
2. If current need to be injected for a particular test, it should be done in the phase selected
by the
3. Follow the sequence for positioning the auxiliary contacts before testing:
