4. Setup and Pairing Instructions

This section details how to set up and pair the remote controls with the receiver board for different operating modes. It is crucial to follow these steps carefully for proper functionality.

4.1. Clearing Existing Codes (Reset)

Before setting a new mode or pairing, it is recommended to clear any previously stored codes. This ensures a clean setup.

1. Locate the learning button on the receiver board.
2. Press the learning button 8 times consecutively. The indicator light on the receiver will flash, indicating that all stored codes have been cleared.

4.2. Pairing for Momentary Mode

In Momentary mode, the relay remains active only while the remote button is pressed and held. Releasing the button deactivates the relay.

1. Press the learning button on the receiver board 1 time. The indicator light will turn on.
2. Press button "A" on the remote control. Wait approximately 3 seconds.
3. Press button "B" on the remote control. The pairing is successful.

Figure 3: Visual guide for setting up Momentary, Toggle, and Latched modes.

4.3. Pairing for Toggle Mode

In Toggle mode, pressing a button on the remote activates the corresponding relay, and it remains active until the same button is pressed again to deactivate it.

1. Press the learning button on the receiver board 2 times. The indicator light will turn on.
2. Press button "A" on the remote control. Wait approximately 3 seconds.
3. Press button "B" on the remote control. The pairing is successful.

4.4. Pairing for Latched Mode

In Latched mode, pressing button "A" activates Relay 1 and simultaneously deactivates Relay 2 (if active). Pressing button "B" activates Relay 2 and deactivates Relay 1. This mode is commonly used for motor forward/reverse control.

1. Press the learning button on the receiver board 3 times. The indicator light will turn on.
2. Press button "A" on the remote control. Wait approximately 3 seconds.
3. Press button "B" on the remote control. The pairing is successful.

5. Operating Modes Explained

Understanding the different operating modes is key to utilizing the full functionality of the QIACHIP relay switch.

5.1. Momentary Mode

When configured for Momentary mode, the relay will activate only for the duration that its corresponding button on the remote control is pressed. Once the button is released, the relay deactivates. This is suitable for applications requiring temporary activation, such as a momentary door release.

Figure 4: Visual explanation of Momentary, Toggle, and Latched operating modes.

5.2. Toggle Mode

In Toggle mode, a single press of a remote button activates the relay, and it remains active even after the button is released. To deactivate the relay, the same button must be pressed again. This mode is useful for on/off control of lights or other devices.

5.3. Latched Mode

Latched mode provides interlocking control between the two relays. Pressing button "A" activates Relay 1 and simultaneously deactivates Relay 2. Conversely, pressing button "B" activates Relay 2 and deactivates Relay 1. This is ideal for controlling the forward and reverse motion of motors, ensuring only one direction is active at a time.

6. Wiring Diagrams

Correct wiring is essential for safe and proper operation. Always ensure power is disconnected before making any connections.

6.1. Motor Forward and Reverse Wiring

This diagram illustrates how to wire the receiver for controlling a DC motor's forward and reverse movement, typically used in Latched mode.

Figure 5: Wiring connections for motor forward and reverse operation. Connect the motor to the NO (Normally Open) and COM (Common) terminals of both relays, and the power supply to the IN and GND terminals.

6.2. External Power Supply Wiring

If an external power supply is required for the motor or other connected device, follow this wiring configuration.

Figure 6: Wiring connections when using an external power supply for the controlled device. The receiver itself is powered by DC 6~30V, and the external power is routed through the relay contacts.

Terminal Definitions:

• NO: Normally Open pin
• COM: Common pin
• NC: Normally Closed pin
• IN: Power Input (Positive)
• GND: Ground (Negative)

7. Troubleshooting

If you encounter issues with your QIACHIP wireless remote control switch, consider the following common problems and solutions:

• Remote Not Responding / Relay Not Activating:
  • Ensure the receiver board is powered correctly within the 6V-30V DC range.
  • Verify that the remote control has a working battery.
  • The remote and receiver might not be paired correctly. Perform the "Clearing Existing Codes" (Section 4.1) and then re-pair the remote for the desired operating mode (Sections 4.2-4.4). Some users report that initial pairing is necessary even if instructions don't explicitly state it as a first step.
  • Check the distance between the remote and receiver. While it has a long range, obstacles can reduce it.
• Only One Relay Working (in Latched Mode):
  • This often indicates incorrect pairing for Latched mode. Ensure you pressed the learning button 3 times, then pressed button "A", waited, and then pressed button "B" during the pairing process.
  • Clear all codes (Section 4.1) and re-pair specifically for Latched mode (Section 4.4).
• Device Not Turning On/Off:
  • Inspect all wiring connections to ensure they are secure and match the appropriate wiring diagram for your application.
  • Confirm that the connected device (motor, light, etc.) is receiving power and is functioning correctly independently of the relay.
  • Ensure the current and voltage requirements of your connected device do not exceed the relay's maximum ratings (10 Amps, 30 Volts).
