Restore connections and settings to their original values, if they were changedfor testing purposes.11.11 Monitoring11.11.1 Gas medium supervision SSIMGPrepare the IED for verification of settings as outlined in section "Testing the liquidmedium supervision for alarm and lock out conditions" and section "Completing the test"in this chapter.Check that the input logical signal BLOCK is logical zero and that on the local HMI, thelogical signals PRES_ALM, PRES_LO, TEMP_ALM and TEMP_LO are equal to logicalzero.11.11.1.1 Testing the liquid medium supervision for alarm and lock out conditions1. Connect binary inputs to consider gas pressure and gas density to initiate the alarms.2. Consider the analogue pressure input PRESSURE to initiate the alarms.3. Gas pressure lock out input can be used to set PRES_LO signal, check the signalstatus in local HMI under Main menu/Test/Function status/Monitoring/Gasmedium supervision SSIMG/PRES_LO4. Reduce the pressure level input below PresAlmLimit, check for PRES_ALM signalstatus in local HMI under Main menu/Test/Function status/Monitoring/Gasmedium supervision SSIMG/PRES_ALM5. Activate BLOCK binary input, the signals PRES_ALM, PRES_LO shoulddisappear.6. Reset the BLOCK binary input.7. Check for reset lock out input RESET_LO to reset PRES_LO lock out signal.8. Conduct these steps for temperature input as well to detect and reset TEMP_ALM andTEMP_LO signals.9. Continue to test another function or end the test by changing the TestMode setting tooff.1MRK 511 366-UUS - Section 11Testing functionality by secondary injection157Commissioning manual
