4. Operating Modes and Pairing

The AK-C211008 relay module supports three distinct working modes: Click, Self-Lock, and Interlock. Understanding these modes is crucial for proper operation.

4.1 Working Modes Explained

• Click Mode (Momentary): The relay activates only while the remote control button is pressed. It deactivates immediately upon release.
• Self-Lock Mode (Toggle): Pressing the remote control button activates the relay, and it remains active after the button is released. Pressing the same button again deactivates the relay.
• Interlock Mode (Latched): In this mode, only one relay can be active at a time. Pressing one button activates its corresponding relay and deactivates any other active relay within the same interlock group.

4.2 Pairing Remote Controls (Code Learning)

The module features a code learning key to pair remote controls. The process involves pressing the learning key a specific number of times to select the desired mode, then pressing a button on the remote.

4.2.1 Two-Point Click Mode (Momentary)

1. Press the code learning key on the controller once. The LED indicator will blink once and go off.
2. Press any key on the remote control. The LED indicator will blink three consecutive times and go off, indicating successful code matching.
3. The remote control is now set to two-point click mode.

4.2.2 Two-Point Self-Lock Mode (Toggle)

1. Press the code learning key on the controller twice. The LED indicator will blink twice and go off.
2. Press any key on the remote control. The LED indicator will blink three consecutive times and go off, indicating successful code matching.
3. The remote control is now set to two-point self-lock mode.

4.2.3 Two-Point Interlock Mode (Latched)

1. Press the code learning key on the controller three times. The LED indicator will blink three times and go off.
2. Press any key on the remote control. The LED indicator will blink three consecutive times and go off, indicating successful code matching.
3. The remote control is now set to two-point interlock mode.

4.2.4 Two-Point Click and Two-Point Self-Lock Mode

1. Press the code learning key on the controller five times. The LED indicator will blink five times and go off.
2. Press any key on the remote control. The LED indicator will blink three consecutive times and go off, indicating successful code matching.
3. The remote control is now set to two-point click mode and two-point self-lock mode.

4.2.5 Double Self-Lock and Double Interlock Mode

1. Press the code learning key on the controller six times. The LED indicator will blink six times and go off.
2. Press any key on the remote control. The LED indicator will blink three consecutive times and go off, indicating successful code matching.
3. The remote control is now set to double self-lock mode and double interlock mode.

4.2.6 Clearing All Paired Codes

To clear all previously paired remote controls from the module, press the code learning key on the controller eight times. The LED indicator will blink eight times and then go off, indicating that all stored codes have been successfully cleared. This is useful for security purposes if a remote control is lost.

6. Troubleshooting

If you encounter issues with your Dpofirs AK-C211008 Relay Remote Control Switch, refer to the following common problems and solutions:

• Remote Control Not Responding:
  • Check the batteries in the remote control. Replace if necessary.
  • Ensure the remote control is properly paired with the receiver. Refer to Section 4.2 for pairing instructions.
  • Verify that the module is receiving power.
• Limited Range or Intermittent Operation:
  • Ensure the antenna on the relay module is properly connected and positioned.
  • Minimize obstructions between the remote and the module (e.g., thick walls, metal objects).
  • Check for strong electromagnetic interference from other devices operating on similar frequencies.
• Relay Not Activating/Deactivating Correctly:
  • Confirm the wiring connections are secure and correct according to your application.
  • Verify the working mode (Click, Self-Lock, Interlock) is correctly set for your intended operation. If unsure, clear all codes and re-pair in the desired mode.
  • Ensure the load connected to the relay does not exceed the module's maximum current rating (10A).
