5. Schemi elettrici
Proper wiring is crucial for the correct function of the relay module. Refer to the diagrams below for common application scenarios.

Immagine 3: This image displays three wiring diagrams: a Control 12V load wiring diagram (showing connection to a light bulb), a Wiring diagram of an exit switch, and an Access Control Wiring Diagram (illustrating connection to a magneto-electric lock or electric bolt lock).
- Potenza in ingresso: Connect the 12V DC power supply to the +V (positive) and -V (negative) terminals on the module.
- Connessione di carico: Il relè ha tre terminali:
- NO (normalmente aperto): The circuit is open (disconnected) when the relay is inactive and closes (connects) when activated.
- COM (Comune): Questo è il terminale comune per l'interruttore del relè.
- NC (normalmente chiuso): The circuit is closed (connected) when the relay is inactive and opens (disconects) when activated.
6. Programming and Operating Modes
The Bkiyougo MG03 module supports four operating modes: Momentary, Toggle, Latched, and Delay. Follow these steps to program the remote control and set the desired mode.
6.1 Cancellazione dei codici esistenti
Before programming a new remote or changing modes, it is recommended to clear any existing codes from the receiver.
- Premere e tenere premuto il tasto Pulsante di apprendimento on the receiver module for approximately 8 seconds until the indicator light flashes rapidly and then turns off.
- Release the button. All previously stored remote control codes are now cleared.
6.2 Programmazione delle modalità operative
After clearing codes, you can program the desired operating mode.

Momentary Mode (Inch Mode)
The relay activates only while the remote button is pressed and deactivates upon release. Ideal for applications like electric door locks or garage door openers where a brief signal is needed.
- Premere il tasto Pulsante di apprendimento on the receiver module una volta. La spia si accende.
- Press the desired button on your remote control (e.g., button 'A'). The indicator light on the module will flash and then turn off, indicating successful pairing.
- Test: Press and hold the remote button; the relay should activate. Release the button; the relay should deactivate.
Toggle Mode (Self-Locking Mode)
Each press of the remote button toggles the relay state (ON/OFF). Press once to activate, press again to deactivate. Suitable for lights or fans.
- Premere il tasto Pulsante di apprendimento on the receiver module due volte. La spia si accende.
- Press the desired button on your remote control (e.g., button 'A'). The indicator light on the module will flash and then turn off, indicating successful pairing.
- Test: Press the remote button once; the relay should activate. Press it again; the relay should deactivate.
Latched Mode (Interlock Mode)
One button activates the relay, and another button deactivates it. Requires two distinct buttons on the remote.
- Premere il tasto Pulsante di apprendimento on the receiver module tre volte. La spia si accende.
- Press the first desired button on your remote control (e.g., button 'A'). The indicator light will flash.
- Press the second desired button on your remote control (e.g., button 'B'). The indicator light will flash and then turn off, indicating successful pairing.
- Test: Press button 'A'; the relay should activate. Press button 'B'; the relay should deactivate.
Delay Mode (Timed Mode)
The relay activates when the button is pressed and remains active for a set duration (e.g., 5, 10, 15, 20 seconds) before automatically deactivating.
- Premere il tasto Pulsante di apprendimento on the receiver module quattro volte for 5-second delay, cinque volte for 10-second delay, sei volte for 15-second delay, or sette volte for 20-second delay. The indicator light will turn on.
- Press the desired button on your remote control (e.g., button 'A'). The indicator light on the module will flash and then turn off, indicating successful pairing.
- Test: Press the remote button; the relay should activate and remain active for the programmed delay time before automatically deactivating.

8. Risoluzione Dei Problemi
If you encounter issues with your Bkiyougo MG03 module, refer to the following common problems and solutions:
- Module not responding to remote:
- Ensure the module is correctly powered (12V DC).
- Check if the remote control battery is functional.
- Verify that the remote is properly paired to the module. Try clearing codes and reprogramming the remote (refer to Section 6.1 and 6.2).
- Ensure the remote is within the effective operating range (up to 50 meters in open areas). Obstacles like thick walls can reduce range.
- Relay not activating/deactivating correctly:
- Confirm the wiring connections to your load are correct (COM, NO, NC terminals).
- Check if the load's current draw exceeds the 10A maximum rating of the relay.
- Verify the operating mode is set as intended (Momentary, Toggle, Latched, or Delay). Reprogram if necessary.
- La spia luminosa non funziona:
- If the indicator light on the module does not illuminate when powered, check the power supply connection.
- If it doesn't flash during programming, try clearing codes and re-attempting the programming sequence.
- Interferenza:
- Strong RF interference from other devices operating on similar frequencies (433MHz) can affect performance. Try relocating the module or reducing interference sources.
