11.13 Monitoring SEMOD53581-1 v111.13.1 Gas medium supervision SSIMG GUID-0A83B4D5-51FF-43CB-8DC7-AFCEA2BC7B69 v2Prepare the IED for verification of settings as outlined in Section "Preparing theIED to verify settings" in this chapter.Values of logical signals for SSIMG protection are available on the local HMIunder Main menu/Tests/Function status/Monitoring/InsulationGas(63)/SSIMG(63):x, where x = 1, 2,....21.The Signal Monitoring in PCM600 shows the same signals that are available on thelocal HMI.Check that the input logical signal BLOCK is logical zero and that on the localHMI, the logical signals PRESALM, PRESLO, TEMPALM, TEMPLO, ALARM andLOCKOUT are logical zero.11.13.1.1 Testing the gas medium supervision for pressure alarm and pressurelockout conditions GUID-768DAAC8-F89D-4401-B86D-9B26FD7224F6 v31. Connect binary inputs to consider gas pressure and gas density to initiate thealarms.2. Consider the analogue pressure input SENPRES and set SENPRES to a valuelower than PresAlmLimit or activate binary input signal SENPRESALM, checkthat outputs PRESALM and ALARM are activated after a set time delay oftPressureAlarm.3. Gas pressure lockout input SETPLO can be used to set PRESLO.4. Also, reduce further the pressure level input below PresLOLimit or activatethe binary input signal SENPRESLO, check that PRESLO signal appears aftera set time delay of tPressureLO.5. Activate BLOCK binary input and check that the outputs PRESALM, PRESLO,ALARM and LOCKOUT disappear.6. Reset the BLOCK binary input.7. Make sure that pressure lockout condition exists and then activate the resetlock out input RESETLO and check that the outputs PRESLO and LOCKOUTreset.Section 11 1MRK 504 165-UEN ATesting functionality by secondary injection262 Transformer protection RET670 2.2 IECCommissioning manual
