    3.3. Mounting 3.3.1. DIN Rail Mounting If the STT700 is to be installed on DIN rail option 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 19: Mounting Module In Housing

    3.3.2. Mounting Module in Housing The STT700 module can be installed in a variety of housings suitable for field mounting (2” or 50mm pipe mount), direct head mounting, or wall mounting. Ensure that the installation location is suitable for reliable transmitter operation (e.g. for high temperature applications, a thermowell extension is recommended to minimize failure rates due to high ambient temperatures near the transmitter).

  • Page 25: Figure 11 -Stt700 Module 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 module terminal block. Route the wires through the pre-moded channels on top of the terminal module. Connect the loop power wiring shield to Earth Ground only at the power supply end.

  • Page 26: Digital System Integration Information

    The positive and negative loop wires are connected to the positive (+) and negative (–) terminals on the STT700. Barriers can be installed per Honeywell’s instructions for transmitters to be used in intrinsically safe applications. Note: Problems detected as non-critical diagnostics may affect performance without driving the analog output to the programmed burnout level (for HART only).

  • Page 27: Grounding And Lightning Protection

    3.4.4. Grounding and Lightning Protection Connect a wire from the mounting screws to Earth Ground to make the protection effective. Use size 14 AWG or 2.0mm bare or green covered wire for this connection. For ungrounded thermocouple, mV, RTD or ohm inputs, connect the input wiring shield(s) to the same Earth Ground connection.

  • Page 32: Startup

    The actual steps in a startup procedure vary based on the type of transmitter and the measurement application. In general, the procedures in this section are based on using Honeywell MC Toolkit, with a HART or DE variant, to check the transmitter input and output under static process conditions, and make adjustments as required initiating full operation with the running process.

    4.1.4. Constant Current Source Mode Procedure Figure 17 – Current Loop Test Connections 1. Refer to Figure 17 for test connections. Verify the integrity of electrical components in the output current loop. 2. Establish communication with the transmitter. For these procedures, the values of components in the current loop are not critical if they support reliable communication between the transmitter and the MC Toolkit.
