Collective Malfunction (FbCollectiveMalfunction)Function description:This function block has been designed to only collect serious errors that would causea system shutdown.If the "xEnableSystem" or "xNightVentilation" input is activated and one of theinputs "xMains", "xEmergencyOff", "xStartupError", "xErrorFanSupplyAir","xErrorFanExhaustAir", "xFrostAlarmAir", "xFrostAlarmWater", "xErrorPump","xFireAlarm", "xErrorDamperSupplyAir", "xErrorDamperSupplyAir","xMalfunction1" or "xMalfunction2" is set to TRUE, an alarm is issued.The error messages can be either visual or audible messages. An audible errormessage can be triggered via the “xHorn“ output until the error is acknowledged viathe “xQuit“ input. The visual error message can be triggered via the“xSignalLamp“ output. With every error message that appears, the error indicatorlamp starts to blink with a frequency of 1 Hz and the horn is activated.If the error is acknowledged via the “xQuit“ input, the error indicator lamp will be litcontinuously. Only if there is no longer an error at the inputs is it possible to deletethe the error message via the "xQuit" input.At the same time, the "xSystemError" output issues a collective malfunction alarm(non-blinking) that shuts down the system via the FbStartStop function block.The "wStatus" output provides the specific error message in the order of priority.Note:1.) If you also want to receive error messages when the system is turned off,"EnableSystem" should be permanently set to TRUE.2.) The FuStatus function converts the "wStatus" status message into a plaintext message.Subject to design changes WAGO Kontakttechnik GmbH & Co.
