  • Page 4: Important Notes

    The temperature transmitter TRV 5-40 is designed for the connection of three temperature sensors TRG 5-6x (platinum resistance thermometer Pt 100 to EN 60751). The temperatures measured by the temperature sensors are converted by the temperature transmitter TRV 5-40 and sent to the CAN bus in the form of a data telegram.
  • Page 5: Function

    (pressurised) hot water installations according to TRD and EN 12952 and EN 12953. Function The temperature transmitter TRV 5-40 consists of the safety part for temperature limiting and the part for temperature monitoring & control. The safety part is connected with the temperature sensor. The temperature sensor detects the tem- perature and sends the measured values to the safety part of the temperature transmitter, where the measured values are recorded redundantly and monitored.

    If two or more system components are connected in a CAN bus the first and the last item of equipment must be provided with a terminating resistor of 120 Ω (terminals ). We recommend that you use the TRV 5-40 equipped with the connector fitted with the terminating resistor either as first or as last equipment.

  • Page 19: Systematic Malfunction Analysis

    System Malfunctions – continued – Systematic malfunction analysis The sources of malfunctions occurring in CAN bus systems operating with several bus-based stations must be analysed systematically since faulty components or incorrect settings can give rise to negative interactions with intact bus devices in the CAN bus system. These unwanted interactions can cause error messages in fully functional bus devices, which will make fault detection even more difficult.

  • Page 21: Note

    The switchpoints should be checked during commissioning and whenever the measuring elements of the temperature sensors or of the temperature transmitter TRV 5-40 are being exchanged. To check the switchpoint “MAX temperature limit (°C)” the adjusted limit value must be exceeded.
