2. Informació de seguretat

Working with electronics and soldering irons requires adherence to safety precautions. Failure to follow these guidelines may result in injury or damage to components.

• Treballeu sempre en una zona ben ventilada per evitar inhalar els fums de la soldadura.
• Use appropriate eye protection (safety glasses) to shield against splashes or flying debris.
• Ensure your soldering iron is placed in a secure stand when not in use and is unplugged when unattended or finished.
• Eviteu tocar la punta calenta del soldador.
• Be aware of hot components after soldering. Allow them to cool before handling.
• Keep a fire extinguisher or fire blanket nearby.
• Always disconnect power before making any changes to the circuit.
• This kit contains small parts and is not suitable for young children without adult supervision.

4. Instruccions de muntatge

Before starting, ensure you have the necessary tools: a soldering iron, solder, wire cutters, needle-nose pliers, and a multimeter (optional but recommended). Follow the silk-screened labels on the PCBs for component placement.

4.1 General Soldering Tips

• Heat both the component lead and the PCB pad simultaneously.
• Apply a small amount of solder to the heated joint. It should flow smoothly and form a shiny, concave fillet.
• Remove the solder, then the iron.
• Trim excess leads with wire cutters.

4.2 Component Placement Order

It is generally recommended to solder components in order of height, starting with the lowest profile components first. This prevents taller components from obstructing access to smaller pads.

1. Resistors and Diodes: Solder all resistors and diodes. Pay attention to the polarity of diodes (band indicates cathode).
2. IC Sockets: Solder the IC sockets. Ensure the notch on the socket aligns with the notch on the PCB silk screen.
3. Ceramic Capacitors and Crystals: Solder these components. Ceramic capacitors typically do not have polarity.
4. LED: Solder the LEDs. Note their polarity: the longer lead is typically the anode (+), and the shorter lead is the cathode (-). The flat side of the LED body usually indicates the cathode. Match this to the PCB marking.
5. Electrolytic Capacitors: Solder electrolytic capacitors. These are polarized; the longer lead is positive (+), and the stripe on the body indicates the negative (-) lead. Match to the PCB markings.
6. Transistors: Solder the transistors, ensuring their flat side or pinout matches the PCB silk screen.
7. Terminal Blocks and Power Connector: Solder these connectors.
8. Cable d'antena: Solder the antenna wire to the designated pad on the transmitter board.
9. Insert ICs: Carefully insert the Integrated Circuits into their respective sockets. Ensure the notch on the IC aligns with the notch on the socket and PCB. Bend the pins slightly inward if necessary to align with the socket holes.

5. Instruccions de funcionament

Once both the transmitter and receiver boards are fully assembled and inspected for soldering errors, you can proceed with operation.

1. Connexió d'alimentació: Connect a suitable DC power supply (refer to specifications for voltage range) to the power input terminal on both the transmitter and receiver boards. Ensure correct polarity.
2. Connexió de 2 fils: Connect the two output wires from the transmitter board to the corresponding input terminals on the receiver board. These are typically labeled for data transmission.
3. Channel Activation: The transmitter board features input terminals for activating channels. By connecting these inputs to a common ground or positive voltage (depending on the design, refer to the schematic if provided), you can activate the corresponding output channels on the receiver board.
4. Output Monitoring: The receiver board will have output terminals (and possibly LEDs) that indicate the status of each channel. Connect your desired devices (e.g., relays, motors, other circuits) to these output terminals.

The 10-channel functionality allows for independent control of up to 10 different functions or devices via the 2-wire communication link.

6. Manteniment

The Whadda WSRC8023 kit requires minimal maintenance once assembled correctly.

• Keep the boards clean and free from dust and debris. Use a soft brush or compressed air if necessary.
• Periodically inspect solder joints for any signs of cracking or corrosion, especially if the device is subjected to vibration or extreme temperatures. Re-solder any faulty joints.
• Ensure all wire connections to terminal blocks are secure.
• Store the assembled unit in a dry, cool environment.

7. Solució De Problemes

If your remote control system is not functioning as expected, consider the following troubleshooting steps:

• Sense energia: Check power supply connections and polarity. Ensure the power supply is providing the correct voltage i corrent.
• No Channel Response: Verify the 2-wire connection between transmitter and receiver. Check for continuity in the wires. Ensure the correct input on the transmitter is being activated.
• Incorrect Channel Response: Double-check component placement and polarity, especially for ICs, diodes, and electrolytic capacitors. Inspect all solder joints for shorts or cold joints.
• Funcionament intermitent: This can often be caused by cold solder joints or loose connections. Re-inspect all solder points and terminal block connections.
• Component Overheating: Immediately disconnect power. This usually indicates a short circuit or incorrect component placement. Carefully review the assembly steps and component polarities.
