4. Oppsett og paring
This section guides you through pairing the remote control with the receiver module and setting the desired operating mode.
4.1 Clearing Existing Codes
- Press and hold the 'Learn Key' button on the receiver module for approximately 8 seconds.
- The indicator light will flash rapidly, then turn off, indicating that all previously learned codes have been cleared.
4.2 Pairing the Remote Control (Learning Code)
After clearing, you can pair the remote control in one of the four operating modes:

Image 4.1: Operating Modes for Pairing.
- Momentan Mode: Press the 'Learn Key' button once. The indicator light will flash once. Then, press the desired button on your remote control (e.g., 'A'). The indicator light will flash rapidly and then turn off, confirming successful pairing in Momentary mode. In this mode, the relay activates only while the remote button is held down.
- Bytt modus: Press the 'Learn Key' button twice. The indicator light will flash twice. Then, press the desired button on your remote control. The indicator light will flash rapidly and then turn off. In this mode, one press of the remote button activates the relay, and another press deactivates it.
- Låsemodus: Press the 'Learn Key' button three times. The indicator light will flash three times. Then, press button 'A' on your remote control, followed by button 'B'. The indicator light will flash rapidly and then turn off. In this mode, button 'A' activates the relay, and button 'B' deactivates it.
- Delay Mode (5s/10s/15s/20s): Press the 'Learn Key' button four, five, six, or seven times respectively for 5, 10, 15, or 20-second delay. The indicator light will flash accordingly. Then, press the desired button on your remote control. The indicator light will flash rapidly and then turn off. In this mode, the relay activates when the button is pressed and automatically deactivates after the set delay time.

6. Operating Modes Explained
The Bkiyougo MG02 supports four distinct operating modes, each suitable for different applications:
- Momentan Mode: The relay remains active only as long as the remote control button is pressed. Releasing the button deactivates the relay. Ideal for applications requiring temporary contact, like a garage door opener or an electric strike plate.
- Bytt modus: Pressing the remote control button once activates the relay, and it stays active. Pressing the same button again deactivates the relay. This acts like a standard ON/OFF switch, suitable for lights or fans.
- Låsemodus: This mode typically uses two buttons on the remote. Pressing one button (e.g., 'A') activates the relay, and it stays active. Pressing another button (e.g., 'B') deactivates the relay. This is useful for distinct ON and OFF controls.
- Forsinkelsesmodus: Pressing the remote control button activates the relay, and it remains active for a pre-set duration (5, 10, 15, or 20 seconds) before automatically deactivating. This is useful for timed operations, such as a temporary light or a door release with automatic re-locking.
7. Feilsøking
If you encounter issues with your Bkiyougo Wireless Relay Switch, refer to the following common troubleshooting steps:
- Enheten svarer ikke:
- Ensure the receiver module is correctly powered (DC 12V). Check power connections.
- Kontroller at batteriet i fjernkontrollen ikke er utladet.
- Confirm the remote control is properly paired with the receiver. Try re-pairing the remote as per Section 4.2.
- Check for obstructions or excessive distance between the remote and receiver. The maximum range is 50 meters in open areas.
- Feil driftsmodus:
- If the relay behaves unexpectedly (e.g., stays on in Momentary mode), it might be programmed to a different mode. Clear all codes (Section 4.1) and re-pair the remote in the desired mode (Section 4.2).
- Intermitterende operasjon:
- Strong RF interference from other devices can affect performance. Try relocating the receiver or reducing interference sources.
- Ensure the antenna on the receiver module is not obstructed or damaged.
- Relay Not Switching Load:
- Verify that the load's voltage and current requirements do not exceed the relay's specifications (10A, 1V-250V).
- Check all wiring connections to the NO, NC, and COM terminals for secure contact. Refer to Section 5 for correct wiring.
8. Sikkerhetsinformasjon
Les og følg disse sikkerhetsreglene for å unngå skade eller skade på enheten:
- Elektrisk sikkerhet: Always disconnect power to the circuit before installing, wiring, or performing maintenance on the relay module. Improper wiring can cause electric shock, fire, or damage to the device.
