17.3ErrorCodes
BelowareshowntheerrorcodeswhichwillbedisplayedontheTHINKControllerifafaultoccursontheappliance.ErrorCodesshownonremoteinterfacesmaybecollective
codesrefertotheTHINKControllerfortheexacterrormessage.Morethanoneerrormaybepresentsothatsubsequenterrorcodeswillbeshownastheoriginalerrorisreset.
Theoccurrenceofanerrorcodewillpreventsomeoralloftheoperationsoftheappliance.
Errorcodesspecifictotherunningoftheenginewillnotpreventthesupplementaryburnerfromoperatingandvisaverse.
Therearethreelevelsoferrorcodewithassociatedresetproceduresasfollows:
1.Automaticreset(AR)Examplesaremainlytodowithtemperaturesensingbutalsoincludemonitoringofthemainssupply.Automaticresetonlyoccursifthefault
conditioniseliminated.
2.Userreset(UR)Anexamplewouldbetherestorationofthegassupplytoenableignition.
3.Servicereset(SR)ariseswhenaresetoftheconditionneedstobeaccompaniedbytheattendanceofaserviceengineer.
Therearetwospecialconditions:
1.Automaticresetafterpowerdown(ARP)anautomaticresetcanonlyoccuraftertheelectricalsupplyisinterrupted.Usuallythisimpliesdatacorruptionandisineffect
a'reboot'ofthePCB.
2.Norestartpossible(NRP)occursifthereiscorruptionofstoreddataforinstanceandimpliesthatthePCBwillhavetobereplaced.
