Installation and Wiring Guide
Installation Steps
- Confirm that the installation location has no severe vibration or corrosive gases, and the ambient temperature meets the requirements.
- Fix the TMS12 on a bracket or pipe, ensuring the sensor insertion depth is sufficient.
- Connect the power supply, output signal, and sensor cables according to the wiring diagram, paying attention to polarity.
- After power-on, check the indicator light status to confirm the device starts normally.
Wiring Precautions
- Use shielded cables, with the shield grounded at one end, to reduce electromagnetic interference.
- Route power and signal lines separately to avoid parallel wiring.
- It is strictly prohibited to plug or unplug wiring terminals while energized.
Parameter Setting and Calibration
The TMS12 supports parameter setting via HART communicator or RS485 communication. Users can configure range, damping time, units, etc.
- Range Setting: Set the temperature values corresponding to 4mA and 20mA according to the actual measurement range.
- Damping Time: Adjust the output response speed to suppress fluctuations.
- Calibration: Use a standard signal source for zero and full-scale calibration.
Common Troubleshooting
When encountering abnormalities, refer to the following steps to quickly locate the problem.
- Output signal fixed at 4mA or 20mA: Check whether the sensor is open or short-circuited.
- Output signal fluctuates greatly: Check whether the wiring is loose and whether the shielding is effective.
- No output signal: Confirm whether the power supply voltage is within the 12-36V DC range.
- Communication failure: Check whether the RS485 address and baud rate settings are consistent.
Summary
The TMS12 Chinese manual provides detailed information on product specifications, installation, setup, and maintenance points. Correct use ensures long-term stable operation of the temperature transmitter and improves process control accuracy.
