Testing the liquid medium supervision for alarm and lock out conditions

1. Connect the binary inputs to consider liquid level to initiate the alarms.
2. Consider the analogue level input LEVEL to initiate the alarms.
3. Liquid level lock out input can be used to set LVL_LO signal, check the signal status in
local HMI under Main menu/Test/Function status/Monitoring/Liquid medium
supervision SSIML/LVL_LO
4. Reduce the liquid level input below LevelAlmLimit, check for LVL_ALM signal status in
local HMI under Main menu/Test/Function status/Monitoring/Liquid medium
supervision SSIML/LVL_ALM
5. Activate BLOCK binary input, the signals LVL_ALM, LVL_LO should disappear.
6. Reset the BLOCK binary input.
7. Check for reset lock out input RESET_LO to reset the LVL_LO lock out signal.
8. Conduct these steps for temperature input as well to detect and reset TEMP_ALM and
TEMP_LO signals.
9. Continue to test another function or end the test by changing the
Off .

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
10.12.3.1

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:
POSCLOSE
POSOPEN
4. Test of CB contact travel time
