4. Setup jeung Wiring

Proper connection of the module is crucial for its functionality. Refer to the wiring diagram below for detailed connections.

4.1 suplai kakuatan

• The module is powered via a Type-C port, requiring a 5V DC input.
• Connect a standard Type-C 5V power source to the module's Type-C port.
• The module provides a stable 3.3V output for the connected sensor.

4.2 Beban Cell Connection

Connect your load cell to the module using the following pins:

• E+ (Excitation+): Connect to the positive excitation of the load cell.
• E- (Excitation-): Connect to the negative excitation of the load cell.
• S+ (Signal+): Connect to the positive signal output of the load cell.
• S- (Signal-): Connect to the negative signal output of the load cell.

4.3 Alarm Output Connection

The module provides two alarm output pins:

• AL1: Alarm output 1.
• AL2: Alarm output 2.

These can be connected to external relay modules or other control circuits to trigger actions based on weight thresholds.

4.4 Interface Komunikasi

The module supports TTL communication with Modbus RTU protocol. Connect to your communication device (e.g., PLC, microcontroller, computer via a TTL-to-USB converter) using the following pins:

• RX (nampi): Data input to the module.
• TX (Pangiriman): Data output from the module.
• GND: Ground connection for communication.
• 5v: Power supply for communication (optional, depending on external device).

5. Parentah Operasi

The module features a 5-digit LED display and four control buttons for local operation and debugging.

5.1 Fungsi Tombol:

• Settings (设置): Used to enter or exit configuration menus and confirm selections.
• Shift / Tare (移位/除皮): Used to shift digits during numerical input or to perform a tare operation (zeroing the current weight).
• Add Key / Clear (加键/清零): Used to increment values during numerical input or to clear certain settings.
• Subtract Key / Zero Point (减键/零点): Used to decrement values during numerical input or to set the zero point.

5.2 Weighing Display

Once powered and calibrated, the 5-digit LED display will show the real-time weight measured by the connected load cell.

5.3 Kalibrasi

Calibration is essential for accurate measurements. The module supports calibration via both the onboard buttons and through the communication interface. Refer to the detailed protocol document for communication-based calibration procedures. For button-based calibration:

1. Enter calibration mode using the 'Settings' button.
2. Follow the on-screen prompts to set the zero point using the 'Subtract Key / Zero Point' button.
3. Apply a known reference weight and adjust the span using the 'Add Key / Clear' and 'Subtract Key / Zero Point' buttons.
4. Save settings using the 'Settings' button.

5.4 Fungsi Alarm

The module can be configured with upper and lower weight limits. If the measured weight exceeds the upper limit or falls below the lower limit, the corresponding alarm output (AL1 or AL2) will activate. These limits can be set via the buttons or through the communication interface.

6. Communication (TTL & Modbus RTU)

The module provides a TTL serial communication interface and supports the standard Modbus RTU protocol, allowing for integration into larger control systems.

6.1 TTL Interface

The TTL interface operates at 5V logic levels. Ensure your connecting device is compatible or use appropriate level shifters.

6.2 Modbus RTU Protokol

The module acts as a Modbus RTU slave device. You can read weighing data, set alarm thresholds, and perform calibration commands by sending Modbus RTU requests from a master device (e.g., PLC, HMI, PC software).

For detailed Modbus register addresses, function codes, and communication parameters (baud rate, parity, stop bits), please refer to the specific Modbus RTU protocol documentation provided by the manufacturer. This documentation is essential for developing custom software or configuring Modbus master devices.

7. Tips pamaké

• Jelas tampilan: The 5-digit LED display provides clear and immediate feedback on the measured weight.
• Kapasitas Timbangan: The maximum weighing capacity of your setup depends entirely on the specifications of the load cell connected to the module, not the module itself. Always ensure your load cell is rated for the expected weight range.
• Konfigurasi Alarm: Utilize the upper and lower limit alarm functions to automate processes or alert operators when weight thresholds are met. These can be adjusted via buttons or communication.
• Communication for Advanced Control: For complex systems or remote monitoring, leverage the Modbus RTU communication to integrate the module with PLCs or other industrial control systems.
