5. Setup and Installation
Follow these steps for proper installation of the eMylo RF Motor Controller Module:
- Power Disconnection: Before starting, ensure that the power supply to your motor system is completely disconnected to prevent electric shock.
- Identify Wiring: Identify the positive (Live line) and negative (Null line) wires from your DC 5-24V power source and the corresponding wires for your DC motor (Load).
- Connect Power Input: Insert the power supply's positive (Live line) and negative (Null line) wires into the input terminals of the controller module. The module features insulated push-in terminals for easy, tool-free connection. Simply press the terminal lever, insert the wire, and release.
- Connect Motor Output: Connect the motor's wires to the output terminals of the controller module. Ensure correct polarity for desired forward/reverse operation. If the motor direction is incorrect, you can swap the output wires.

- Secure Connections: Verify all connections are firm and secure. The pre-soldered cabling on the module ensures reliable contact.
- Power On: Reconnect the power supply. The module is now ready for operation.
Remote Control Pairing (if necessary):
The remote controls are typically pre-paired. If re-pairing is needed or if you wish to add new remotes, refer to the specific pairing instructions provided with your product packaging. Generally, this involves pressing a learning button on the module and then a button on the remote.
6. Operating Instructions
The eMylo RF Motor Controller Module operates using the provided 433MHz remote controls. Each remote typically has three buttons: Forward, Reverse, and Stop.

- Forward Movement: Press the designated "Forward" button on the remote control to activate the motor in the forward direction.
- Reverse Movement: Press the designated "Reverse" button on the remote control to activate the motor in the reverse direction.
- Stop Function: Press the "Stop" button to halt the motor's movement. The module is designed to stop the motor automatically when it reaches its limit or if a single press is used for full travel.
Remote Control Range:
The remote control offers a stable signal with an indoor range of 20 to 50 meters, allowing control through walls, floors, and doors without significant interference.

7. Maintenance
- Cleaning: Use a dry, soft cloth to clean the module. Do not use liquid cleaners or solvents.
- Inspection: Periodically check wiring connections to ensure they remain secure.
- Battery Replacement: If remote control range decreases or buttons become unresponsive, replace the battery in the remote control. Refer to the remote's specific instructions for battery type and replacement procedure.
- Storage: If storing the module for an extended period, disconnect it from the power supply.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not respond to remote. | No power to module; Remote battery low/dead; Remote not paired; Obstruction between remote and module. | Check power connections; Replace remote battery; Re-pair remote control (see Setup section); Reduce distance or remove obstructions. |
| Motor moves in the wrong direction. | Incorrect wiring of motor output. | Disconnect power and swap the motor's output wires connected to the module. |
| Module LED indicator is off. | No power supply; Faulty module. | Check power input connections and power source; If power is confirmed, the module may be faulty and require replacement. |
