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.
Liquid medium supervision SSIML
Prepare the IED for verification of settings as outlined in section
supervision SSIML"
and section
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the
logical signals LVL_ALM, LVL_LO, TEMP_ALM and TEMP_LO are equal to logical zero.
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 TestMode setting to
Off.
Completing the test
