5. Operating Instructions
5.1 Configuration via HART Protocol
The TTH200 supports HART communication, allowing for remote configuration, monitoring, and diagnostics. A HART communicator or compatible software is required.

- Connect the HART communicator to the transmitter's output loop.
- Use the communicator's interface to set parameters such as sensor type, measurement range, output scaling, and damping.
- Verify the configuration settings before putting the transmitter into service.
5.2 Data Monitoring
Once configured, the transmitter will output a 4-20 mA signal proportional to the measured temperature. The HART protocol also allows for digital access to process variables, device status, and diagnostic information.
6. Maintenance
6.1 Calibration
The transmitter is supplied with a calibration valid for one year, traceable to National Standards. Regular recalibration is recommended to ensure continued accuracy, especially in critical applications.
6.2 Cleaning
Clean the exterior of the transmitter with a soft, damp cloth. Do not use abrasive cleaners or solvents that could damage the polycarbonate housing.
6.3 Storage
If storing the transmitter, ensure it is kept within the specified storage temperature range of -50°C to 85°C (-58°F to 185°F) in a dry environment.
7. Troubleshooting
This section provides general guidance for common issues. For complex problems, contact technical support.
- No Output Signal:
- Check power supply connections and voltage (11-42 VDC).
- Verify sensor wiring and integrity.
- Ensure correct configuration via HART protocol.
- Inaccurate Readings:
- Check sensor type and range settings in the configuration.
- Inspect sensor for damage or incorrect installation.
- Consider recalibration if accuracy drift is suspected.
- HART Communication Failure:
- Ensure HART communicator is properly connected to the loop.
- Verify loop impedance is within HART specifications.
