23.3.4. Troubleshoot and clear the system error alarm
OccasionallytheinvertersystemwillactivateaSystem Error alarm.Thismayhappenaftermomentary
ACoutages,breakertrips,falsecommunicationproblems,orotherunusualevents.TheSystem Error
alarmisaremindertochecktheT2Slogfile.Itisrecommendedtodownloadandviewthelogfileforany
possibleproblems.Downloadingthelogfilewillalsoclearthealarm.
To check the T2S log file:
1. DeterminewhichT2Sisthesourceofthealarm.NavigatetoSystems > Inverter System > Live
Alerts andlookfortheCheck Log File alarminthelist.WhenevertheCheck Log File alertis
active,theSystem Error alarmwillalsobeactive.TheCheck Log File alertwillbeshownwiththe
serialnumberoftheT2Sthatiscausingthealert.
2. GotoSystems > Inverter System > Inventory > T2Ss andselecttheGO TO buttonoftheT2S
identifiedinthepreviousstep.
3. IntheT2S Expert Operations table,selectGet Log File from T2S.Thiswillinitiateatransferof
thelogfilefromtheT2S.
4. Oncethelogfilehasbeenreceived,selectDownload tosavethefiletoyourcomputer.
5.
Openthefileandlookforanyevententriesthatmightindicateapersistentissue.Forexample,
modulefailuresorcommunicationproblems.Theseproblemsmayindicatetheneedtoreplacea

23.3.5. Phase saturation alarm
ThePhase Saturation alarmindicatesthatoneormorephasesaredrawingtoomuchpower.Thealarm
activateswhentheratioofactualoutputpower,overthetotalinstalledpower(excludingredundant
inverters),exceedstheSaturation Alarm Threshold parameterconfiguredontheT2Scontroller.This
valueisnormallysetto100percent.ToverifythethresholdvaluedownloadtheT2Sconfiguration.
To check the T2S Saturation Threshold:
1. GotoSystems > Inverter System > Inventory > T2Ss andselecttheGO TO buttonoftheT2S
identifiedinthepreviousstep.
2. IntheT2S Expert Operations table,selectGet Configuration File from T2S.Thiswillinitiatea
transferoftheconfigurationfilefromtheT2S.
3. Oncethefilehasbeenreceived,selectDownload tosavethefiletoyourcomputer.
4. Openthefileinatexteditorandsearchfor“Saturationalarmthreshold”.Thesearchshouldfinda
linesimilarto:“;556;;Saturationalarmthreshold;;80;;%;“.Thevalue80indicatesthethresholdis
80percent.
