3.1. Komponentidentifikation

Billede 3.1: Detaljeret view of the KR3001A receiver module, highlighting the antenna, learning button, indicator light, and terminal connections (NC, COM, NO, V+, V-).
The receiver module features an antenna for signal reception, a learning button for pairing, an indicator light for status, and screw terminals for connections:
- V+: Positive power input (DC 5V-60V)
- V-Negativ strømindgang (jord)
- KOM: Common terminal of the relay
- INGEN: Normally Open terminal of the relay (disconnected from COM when relay is off, connected when on)
- NC: Normally Closed terminal of the relay (connected to COM when relay is off, disconnected when on)
3.2. Wiring Principles
The KR3001A is a dry contact relay with passive output. This means the relay acts as a switch, controlling the circuit of your connected device without providing power to it. You must provide external power to your device.
Video 3.2.1: This video demonstrates the wiring and working principles of the QIACHIP 1-channel remote control switch, including how to connect power and a load (e.g., an LED light) to the relay terminals.
For basic operation, connect the power supply to the V+ and V- terminals. The device you wish to control (e.g., an LED light, motor) should be connected to the COM and either NO or NC terminals, depending on the desired default state (normally open or normally closed).

Image 3.2.2: Wiring diagrams illustrating how to connect a light bulb to the receiver using either the Normally Open (NO) or Normally Closed (NC) contacts. The receiver's power input is DC 5V-60V.
When the relay is not activated, the NO port is disconnected from COM, and the NC port is connected to COM. When the relay is activated, the NO port connects to COM, and the NC port disconnects from COM.
4. Driftstilstande
The KR3001A supports four operating modes: Momentary, Toggle, Latched, and Delay. These modes determine how the relay responds to button presses on the remote control.
Video 4.1: This video demonstrates the Momentary, Toggle, and Latched operating modes of the KR3001A receiver with a remote control and an LED indicator.

Image 4.2: Visual representation of the four operating modes: Momentary (press and hold ON, release OFF), Toggle (press ON, press again OFF), Latched (Press A ON, Press B OFF), and Delay OFF (press button, turns off after a set time).
4.1. Momentantilstand
In Momentary mode, the relay remains activated only while the remote control button is pressed. Releasing knappen deaktiverer relæet.
- Handling: Press and hold the remote button.
- Resultat: The connected device turns ON.
- Handling: Release the remote button.
- Resultat: The connected device turns OFF.
4.2. Skift tilstand
In Toggle mode, each press of the remote control button alternates the state of the relay. One press turns it ON, the next press turns it OFF.
- Handling: Press the remote button once.
- Resultat: The connected device turns ON.
- Handling: Press the same remote button again.
- Resultat: The connected device turns OFF.
4.3. Låst tilstand
Latched mode requires a remote control with at least two buttons (e.g., A and B). Pressing one button activates the relay, and it remains active until the other button is pressed to deactivate it.
- Handling: Press button 'A' on the remote.
- Resultat: The connected device turns ON.
- Handling: Press button 'B' on the remote.
- Resultat: The connected device turns OFF.
4.4. Delay Mode
In Delay mode, the relay activates when the button is pressed and automatically deactivates after a preset time (e.g., 5s, 10s, 15s, 20s). The specific delay time is configured during the pairing process.
- Handling: Press the remote button.
- Resultat: The connected device turns ON and starts a countdown.
- Handling: After the set delay time.
- Resultat: The connected device automatically turns OFF.
5. Parringsinstruktioner
To use your remote control with the KR3001A receiver, you must first pair them. The pairing process also sets the operating mode.
- Clear Existing Pairings (Factory Reset): To clear all previously paired remote controllers, press the learning button on the receiver 8 times. The indicator light will flash to confirm successful clearing.
- Gå ind i parringstilstand: Press the learning button on the receiver a specific number of times according to the desired operating mode:
- 1 gang: Momentary Mode
- 2 gange: Toggle Mode
- 3 gange: Latched Mode (requires a 2-button remote)
- 4 gange: Delay Off Mode (5 seconds)
- 5 gange: Delay Off Mode (10 seconds)
- 6 gange: Delay Off Mode (15 seconds)
- 7 gange: Delay Off Mode (20 seconds)
- Par fjernbetjening: After pressing the learning button the required number of times, the indicator light on the receiver will flash. Immediately press the desired button on your remote control. The indicator light will flash again to confirm successful pairing.

7. Fejlfinding
If you encounter issues with your QIACHIP KR3001A, please refer to the following common troubleshooting steps:
7.1. No Output Voltage opdaget
If you cannot detect output voltage, troubleshoot as follows:
- Kontrol af ledninger: Ensure the product has been correctly wired. The COM terminal should be jumped to the positive power supply if you intend to switch the positive line of your load.
- Parringsstatus: Verify that the product has been successfully paired with the remote control. Refer to Section 5 for pairing instructions.
- Terminalvalg:
- If the product relay is ON, the detected terminals should be the NO terminal and the negative pole of the power supply.
- If the product relay is OFF, the detection terminals should be the NC terminal and the negative pole of the power supply.
7.2. Remote Control Range Issues
The transmitting distance is rated at 50 meters in open space. Obstacles such as walls, metal structures, or other electronic interference can significantly reduce the effective range. Ensure the antenna is unobstructed and consider the environment when assessing range performance.
