    Figure 1 – STT700 Temperature Transmitter (HART left, DE right) The transmitter measures process temperature and outputs a signal proportional to the measured process variable (PV). Available output communication protocols include 4 to 20mA, Honeywell Digitally Enhanced (DE) and HART protocols. July 2017 STT700 Quick Start Installation Guide...

  • Page 4: Mounting The Transmitter

    SmartLine Temperature Transmitter MOUNTING THE TRANSMITTER DIN Rail Mounting If the STT700 is to be installed on DIN Rail then the main considerations are electrical connections and mechanical fixing. Electrical connections are identical to the bench test instructions except that thermocouple wire is likely to be used with thermocouples. Mechanical fixing of the module is by means of the snap-in DIN Rail Clips which are screwed to the bottom lugs of the module.

  • Page 5: Table 2: Mounting Dimensions

    Mounting Module in Housing The STT700 module can be installed in a variety of housings suitable for direct head mounting, 2'' (50mm) pipe mounting or wall mounting.

    SmartLine Temperature Transmitter Spring Loading Figure 5: Spring Loading and Sensor Assembly Spring loading is available worldwide with direct head mounting. In North America, the spring loading is typically included in the sensor/thermowell assembly and is available with all housings. For non-North American spring loading as shown in Figure 5, simply include the springs under the 33 mm pitch mounting screws, pass the screws through...

  • Page 8: Figure 8: Stt 700 Terminal Connections

    Loop wiring is connected to the transmitter by simply attaching the positive (+) and negative (–) loop wires to the positive (+) and negative (–) terminals on the transmitter terminal block in the electronics housing shown in Figure Route the wires through the pre-molded channels on the connector cap.

  • Page 9: Wiring Variations

    Wiring Variations The above procedures are used to connect power to a transmitter. For loop wiring and external wiring, detailed drawings are provided for transmitter installation in non-intrinsically safe areas and for intrinsically safe loops in hazardous area locations. This procedure shows the steps for connecting power to the transmitter. Grounding and Lightning Protection Connect a wire from the mounting screws to earth ground to make the protection effective.

    The single sensor connections can also be used on a dual input transmitter when a second input is not required. In this case, it is recommended that the second input be configured to none in software. In case of RTD type being configured to 4-wire, this is automatically done. Figure 10: Wiring Diagram for HART Dual Sensor Connections EXLOSION-PROOF CONDUIT SEAL When installed as explosion proof in a Division 1 Hazardous Location, keep...

  • Page 11: Lightning Protector

    LIGHTNING PROTECTOR This device is designed to give the SmartLine temperature transmitter maximum protection against surges such as those generated by lightning strikes. The lightning protector mounts right on the top of the STT700 terminal block, providing easy field wiring and also protection for the EU meter if used. For more details refer to STT700 SmartLine temperature transmitter user’s manual, #34-TT-25-17.

  • Page 12: Figure 12: Installation Without Eu Meter

    Installation • If an EU meter is used, remove the shunt on the Lightning Protector. In all other cases, the shunt must be present. • Remove the cover/cap of the housing (if applicable). The device fits on the top of the transmitter module terminal block and the transmitter output screws (+ and -) fix mechanically the device.
