  • Page 26: Wiring Guidelines

    HZS 7321 TOUCH OPERATING PANEL Wiring Guidelines Ground The terminal must be connected to ground via the assembly on the control cabinet or over the connection provided. It is important to create a low-ohm ground connection, only then can error-free operation be guaranteed. The ground connection must be made with the maximum cross section and largest (electrical) surface possible.
  • Page 27 TOUCH OPERATING PANEL HZS 7321 RS485 • Because the RS485 requires a defined quiescent point, a pull-up and pull-down resistor is required in addition to the termination resistor. The resistors are already implemented in the device. • The 120 Ω terminating resistors must be placed at each bus end.

  • Page 28: Can Bus Setup

    HZS 7321 TOUCH OPERATING PANEL CAN Bus Setup This section explains how to configure a CAN bus correctly. The following parameters must first be set: Station number and data transfer rate. CAN Bus Station Number Each CAN bus station is assigned its own station number. With this station number, data can be exchanged with other stations connected to the bus.

  • Page 29: Can Bus Termination

    TOUCH OPERATING PANEL HZS 7321 CAN Bus Termination In a CAN bus system, both end modules must be terminated. This is necessary to avoid transmission errors caused by reflections in the line. The termination is made by an internal 120 Ω resistor between CAN A (LOW) and CAN B (HIGH).

  • Page 30: Bus

    The maximum number of participants on the M-bus depends on the cable length, data trans- fer rate (Baud rate) and the drivers used in the participants. On the HZS 7321, a maximum of 10 M-bus participants can be used. Each with 6 Unit Loads. 10.2 M-Bus Baud Rate The M-bus supports the following Baud rates: 300, 600, 1200, 2400, 4800 and 9600 Baud.

  • Page 31: Further Information

    TOUCH OPERATING PANEL HZS 7321 10.5 Further Information The M-bus specifications can be found under https://m-bus.com/ and in the corresponding norm. For the initial start-up of the M-bus network, the handbooks for the remote stations (e.g. heat- ing meter) must be reviewed.

  • Page 41: Transport/Storage

    TOUCH OPERATING PANEL HZS 7321 13 Transport/Storage This device contains sensitive electronics. During transport and storage, high mechanical stress must therefore be avoided. For storage and transport, the same values for humidity and vibration as for operation must be maintained! During transport, temperature and humidity fluctuations may occur.

  • Page 42: Storage

    HZS 7321 TOUCH OPERATING PANEL 14 Storage When not in use, store the operating panel according to the storage condi- tions. See chapter 7. During storage, ensure that all protective covers are placed correctly, so that no contamination, foreign bodies or fluids enter the device.

    TOUCH OPERATING PANEL HZS 7321 15 Maintenance During maintenance as well as servicing, observe the safety instructions from chapter 2. 15.1 Cleaning and Disinfecting the Touchscreen CAUTION Before cleaning and disinfecting the touch screen, it must be deactivated by either turning off the terminal or disabling the touchscreen via the application to prevent triggering functions or commands unintentionally! The touch screen can only be cleaned with a soft, damp cloth.

  • Page 44: Service

    HZS 7321 TOUCH OPERATING PANEL 15.2 Service This product was constructed for low-maintenance operation. 15.2.1 Calibrating the Touch Screen The touch screen is calibrated at the factory. You should therefore only recalibrate the touch screen when press-point changes are noticed.

  • Page 45: Buffer Battery

    16 Buffer Battery The exchangeable buffer battery ensures that the clock time (RTC) and SRAM data of the HZS 7321 is preserved in the absence of a supply voltage. A lithium battery is installed at the manufacturer. After delivery of the HZS 7321 and storage of one year, the lifespan of the battery reaches 10 years, if it can be assumed that the module is continually in operation (connected to supply voltage).
