Info

Mechanical designThe HRC3.2 controller consists of a housing base, a housing cover and a printed circuitboard with connection terminals.The controller also has a tool socket, a service LED and a service pin.Cable restraintsConnectionterminalsConnection terminals for roombusConnector for service toolHousing coverConnectionterminalsHousing base6314z02Device labelOpen EnergyManagementEquipment22K4C USLISTED6314z03NoteUse of the labeling fields for handwritten entries:AdrAppl.LocKonnex addressCurrently loaded applicationRoom numberTerminal coversSTOPCaution6314z04Owing to the intrinsic heat generated by thecontroller, terminal covers must not be used,as this can cause overheating.For the same reason, adequate aircirculation must be provided in the locationwhere the controller is installed.Protection from physicalcontactTo prevent accidental physical contact with relay connections carrying voltages inexcess of the SELV voltage range (U eff > 42), the device must be fitted in a housing(preferably a control panel). This enclosure must be accessible only by use of akey or tool.Alternatively, a commercially available contact guard can be used.4/12Siemens HRC3.2 – Room controller CM2N6314enBuilding Technologies 01.09.2008
Connection terminalsA plug-in terminal is provided for the commissioning and service tool.All other terminals are fixed.To avoid incorrect wiring, terminals which can be connected to AC 230 V (supply andrelay outputs) are physically segregated from the other terminals. They are arranged sothat, under normal circumstances, all incoming and outgoing cables can be connectedwithout crossing.STOP CautionCable restraints must be used for the wires to terminalblocks X4 and X5 (AC 230 V).The conductors must be secured with cable ties (seediagram, right).6314z05Service LEDThe red / green service LED displays the operating status for the room controller. Theviewer see the color orange when the red and green LEDs are on at the same time.The service LED states are as follows:LED displayRed blinking: Blinkingfrequency 0.1 second on,1 second offGreen offRed blinking: Blinkingfrequency 0.1 second on,0.1 second offGreen onRed offGreen blinkingRed onGreen blinkingRed offGreen offOperating stateOperating system running; no measuring and controltask is loadedOperating system running; measuring and control taskloaded and in STOPOperating system running; measuring and control taskloaded and in RUN• The blinking frequency is the same as the cycletime for the measuring and control taskOperating system running; measuring and control taskloaded and in RUN• Addressing mode is on: The blinking frequency isthe same as the cycle time for the measuring andcontrol tasks• Address mode is off: Error• No power• ErrorResponse in the eventof a fault• If the management system or communication link fails, this will not affect localoperation• External fuses are required for the relay contacts• The controller comes with a self-resetting thermal fuse to prevent overload damage.DisposalThe device includes electrical and electronic components and must not be disposed ofas domestic waste.Current local legislation must be observed.Siemens HRC3.2 – Room controller CM2N6314enBuilding Technologies 01.09.20085/12
