3.2 Konexio elektrikoak
A detailed wiring diagram is essential for correct electrical connections. Please refer to the diagram provided with your product packaging or official documentation. Below is a textual description of typical connections for the LH86-VRRD model:
- Elikatze-iturria: Connect the appropriate AC/DC power (90-260V or 18-30V) to the designated power terminals (typically labeled 23 and 24).
- Load Cell Input: The device supports 1-4 load cells. Connect the load cell excitation and signal wires to the corresponding terminals:
- EXC+ (Excitation Positive)
- EXC- (Excitation Negative)
- SG+ (Signal Positive)
- SG- (Signal Negative)
- Alarma Irteerak (AL1, AL2): Connect external alarm devices or relays to the alarm output terminals (e.g., 20, 21, 22). These are multi-function Relay/SSR controls.
- Transmit Output (OUT 0-10V): For analog signal output, connect to the 0-10V transmit output terminals (e.g., 16, 17, 18, 19).
- RST/TARE Control: Connect external buttons or control signals for Reset (RST) and Tare (TARE) functions to their respective terminals (e.g., 9, 10).
- Komunikazio Interfazea: If using RS485, RS232, or LAN (RJ45) for data communication, connect to the appropriate communication ports. The device supports MODBUS-RTU protocol.
Abisua: Incorrect wiring can damage the device and pose safety risks. Always consult the specific wiring diagram for your model and ensure power is off during installation.
4. Funtzionamendua
The MYPIN LH86-VRRD is designed for user-friendly operation with its clear 6-digit LED display and intuitive controls.
4.1 Oinarrizko funtzioak
- Weight Indication: The primary 6-digit LED display (PV) shows the current weight measured by the connected load cells.
- Set Value (SV): The secondary display (SV) shows the set point or other configurable parameters.
- START/STOP Control: Use the designated buttons (e.g., 'SET' or 'RST' in combination with other keys) to initiate or halt weighing processes or control sequences.
- Clear TARE Control: The TARE function allows you to zero out the weight of a container or platform, so only the net weight of the item is measured. Use the dedicated TARE button or combination.
- Data/Peak Value Holding: This optional function allows the device to hold the current weight reading or the peak weight detected during a measurement cycle. Refer to the programming section for activation and configuration.
4.2 Programming and Configuration
The device offers various programmable parameters for calibration, alarm settings, output control, and communication protocols. Access the programming menu by pressing and holding the 'SET' button. Navigate through parameters using the arrow keys and confirm changes with 'SET' or 'RST'. Consult the detailed programming guide for specific parameter definitions and adjustment procedures.
