HRC3.2 Room controller

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
