Power Supply: Connect a DC 10V-30V power source to the designated power terminals (PD+ and PD-).

Sensor Connection: Connect your load cell or weighing sensor to the excitation voltage (E+, E-) and signal input (S+, S-) terminals. The device provides 5VDC excitation voltage and supports up to six 350Ω sensors.

Communication: Use the RS232 or RS485 terminals (TXD, RXD, GND for RS232; A, B for RS485) for data communication with external systems, supporting MODBUS RTU protocol.

Switch Outputs: The three-way transistor outputs (OUT1, OUT2, OUT3, COM) can be used to control external devices based on weighing thresholds. They support a 24V/1A load capacity.

Analog Output (for TDA-08A digital+analog and TDA-08C models): Connect to the 0~10V, 0~20mA, or 4~20mA output terminals as required by your system.

Caution: Ensure all power is disconnected before making any wiring connections to prevent damage to the device or injury.

5. Operating Instructions

5.1 Basic Operation

Upon powering on, the device performs an auto-zero function. The six-digit LED display will show the current weight reading.

• ZERO Button: Press this button to manually zero the display. This is useful for taring containers or resetting the zero point.
• SET/CALI Button: Used to enter calibration mode or access system settings. Refer to the detailed programming guide for specific calibration procedures and parameter adjustments.
• SWITCH Button: Controls the transistor switch outputs. Its function may be configurable in settings.
• OFTEN Button: This button is typically used for frequently accessed functions or quick settings, which can be configured by the user.

5.2 Configuration and Settings

The device allows for configuration of various parameters to optimize performance for specific applications:

• Zero Range: Adjust the range within which the auto-zero function operates.
• Filter Strength: Configure the analog filtering level to reduce signal noise and improve stability. Higher filter strength provides more stable readings but may increase response time.
• Baud Rate: Set the communication baud rate for RS232/RS485 to match your external system.
• MODBUS RTU Parameters: Configure slave ID, data format, and other MODBUS specific settings for seamless integration.

Detailed instructions for accessing and modifying these settings are typically found within the device's programming menu, accessible via the SET/CALI button.

6. Maintenance

The EDRIWYIM TDA-08A/C series weight transmitter is designed for robust industrial use and requires minimal maintenance. However, adhering to the following guidelines will ensure its longevity and reliable performance:

• Cleaning: Keep the device clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature range (-30°C to 60°C) and humidity levels. The IP64 protection level indicates resistance to dust and splashing water, but direct exposure to strong jets of water or immersion should be avoided.
• Connections: Periodically check all wiring connections for tightness and signs of corrosion. Loose connections can lead to inaccurate readings or device malfunction.
• Calibration: Regular calibration of the weighing system (including the load cell and transmitter) is recommended to maintain accuracy, especially in critical applications or after prolonged use.

7. Troubleshooting

The TDA-08A/C series features automatic error diagnosis to assist in identifying and resolving issues. If a problem occurs, the device may display an error code or exhibit unusual behavior.

• No Display/Power: Check the DC 10V-30V power supply connection and ensure it is within the specified voltage range. Verify that the power terminals are correctly wired.
• Inaccurate Readings:
  • Check load cell connections (E+, E-, S+, S-).
  • Ensure the load cell is correctly installed and not overloaded.
  • Perform a system calibration.
  • Check for environmental interference (vibrations, temperature fluctuations).
• Communication Failure:
  • Verify RS232/RS485 wiring.
  • Ensure baud rate and protocol settings match between the transmitter and the host system.
  • Check for correct MODBUS slave ID.
• Switch Output Not Functioning:
  • Verify output wiring and load capacity (24V/1A max).
  • Check switch trigger settings in the device configuration.
