5. Instal·lació i cablejat

5.1 Muntatge

The LH86-RR4D controller is designed for panel mounting. Use the provided brackets to secure the device into a standard panel cutout. Ensure adequate ventilation around the unit.

5.2 Cablejat

All wiring connections are made via the terminal block located at the rear of the device. Refer to the wiring diagram below for correct connections. Ensure power is disconnected before making any connections.

• Power Supply (90-260V AC/DC): Connect the main power supply to the designated terminals.
• Load Cell Input (1-4 PCS LOADCELL): Connect the load cell excitation and signal wires to the EXC+, EXC-, SIG+, SIG- terminals. The device supports 1 to 4 load cells.
• Comunicació RS485: Connect RS485 A and B lines to the corresponding terminals for serial communication.
• Sortides d'alarma (AL1, AL2): These are relay outputs for high/low/fast/slow control. Connect external devices as required.
• RST/TARE: Terminal for external reset or tare functions.
• External Sensor Power: If using isolated sensors requiring external power, connect to the +12/40mA, 150mA, or two-wire 24V/30mA outputs as appropriate.

6. Funcionament

6.1 Pantalla i controls

The front panel features a dual LED display and control buttons:

• Visualització de PV (valor de procés): Shows the current measured weight or force.
• Pantalla SV (valor establert): Shows the configured setpoint or target value.
• Unit Indicators: g, kg, T (grams, kilograms, tons) to indicate the measurement unit.
• AL1, AL2, AL3 Indicators: Show the status of the alarm/relay outputs.
• Botó SET: S'utilitza per entrar al mode de programació i confirmar la configuració.
• /RST (Reset) Button: Used for resetting values or functions.
• Botons amunt / avall: Used to navigate menus and adjust parameter values.

6.2 Funcions bàsiques

• Tare Weight Removal: Use the /RST button or a configured external terminal to zero out the current weight, effectively removing the container weight.
• Display Correction: The device supports calibration and correction functions to ensure accurate readings. Refer to the detailed manual for calibration procedures.
• 6-Way Switch Control: The controller offers versatile control options for start/stop, fast forward/reverse, and other functions relevant to filling or batching processes. These are typically configured through the device's settings.

7. Manteniment

To ensure the longevity and optimal performance of your MYPIN LH86-RR4D controller, follow these maintenance guidelines:

• Neteja: Regularly wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Inspecció: Comproveu periòdicament totes les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o corrosió.
• Medi ambient: Maintain a clean, dry, and stable operating environment within the specified temperature and humidity ranges.
• Calibració: If accuracy drifts over time, recalibrate the device according to the procedures outlined in the full instruction manual.

8. Solució De Problemes

If you encounter issues with your LH86-RR4D controller, consider the following common problems and solutions:

• Sense pantalla/alimentació: Comproveu la connexió de la font d'alimentació i assegureu-vos que el volumtage is within the 90-260V AC/DC range. Verify that the power switch (if external) is on.
• Lectures inexactes: Ensure load cells are correctly wired and calibrated. Check for mechanical interference with the weighing platform. Verify that the load cell capacity matches the application.
• No Communication (RS485/RS232): Check the wiring for RS485 A/B or RS232 connections. Verify communication settings (baud rate, parity, data bits) on both the controller and the connected device.
• Relay Outputs Not Activating: Check the setpoints (SV) and ensure they are correctly configured relative to the process value (PV). Verify the wiring of external devices connected to the relay outputs.
• Lectures inestables: Check for electrical noise or interference. Ensure proper grounding. Verify load cell integrity and connections.
