3. Package Contents

The Gemini 3018 is available in Standard and Deluxe versions. Please verify the contents of your package against the list below:

4. Setup

Follow these steps for proper installation and connection of your Gemini 3018 unit:

1. Mounting the Unit: Securely mount the Gemini 3018 main unit within your RC model. If operating in a strong vibration environment, it is crucial to install shock-absorbing rubber fittings to protect the unit.
2. Battery Connection: Connect your dual 2S LiPo batteries to the BATT 1 and BATT 2 ports on the Gemini 3018. Ensure correct polarity. Use MPX adapter cables if necessary.
3. Receiver Connection: Connect your primary and secondary receivers to the SERIAL RX 1 and SERIAL RX 2 ports, respectively. The Gemini 3018 supports dual receiver input for redundancy.
4. FSS-5 Switch Installation: Install the FSS-5 electronic switch in an accessible location on your model. Connect the switch cable to the designated 'SWITCH' port on the Gemini 3018.
5. Servo Connections: Connect your servos to the 18 PWM output channels as required by your model's configuration.
6. HPB Output Connections: If using HPB-compatible devices, connect them to the HPB output ports.
7. S.HUB Mini (Deluxe Version): If you have the Deluxe version, connect the S.HUB Mini units as needed for additional functionality or servo connections. These can be connected to S.BUS1/S.BUS2 servo ports or used with the Dualsky S.HUB MINI ecosystem.

5. Operating Instructions

1. Power On/Off: Use the FSS-5 electronic switch to power on or power off the Gemini 3018 unit and connected components.
2. Monitoring Indicators: Observe the Signal, HV (High Voltage), and Load indicators on the unit. These provide real-time status of signal reception, output voltage, and current load. An 'Alarm' indicator will illuminate if an issue is detected.
3. Fail Safe Function: The FSS-5 switch incorporates a Fail Safe function. In the event of damage or disconnection of the switch, the main body of the Gemini 3018 will not lose power, ensuring continued operation of your model.
4. Programming Outputs: The S.BUS input and 4 channels of PWM output are programmable. Refer to the detailed programming guide (if provided separately) for specific instructions on configuring these settings to match your receiver and servo requirements.

6. Maintenance

• Regular Inspection: Periodically inspect all connections (battery, receiver, servo, HPB) to ensure they are secure and free from corrosion or damage.
• Cleanliness: Keep the Gemini 3018 unit clean and free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Avoid using solvents or harsh chemicals.
• Ventilation: Ensure the unit has adequate ventilation to prevent overheating, especially during prolonged operation. The aluminum casing aids in heat dissipation.
• Shock Absorbers: If shock-absorbing rubber fittings are installed, regularly check their condition and replace them if they show signs of wear or degradation.
• Battery Health: Monitor the health and charge level of your connected LiPo batteries. Always use properly charged and balanced batteries.

7. Troubleshooting

If you encounter issues with your Gemini 3018, refer to the following common problems and solutions:

• No Power to Model:
  • Check battery connections to BATT 1 and BATT 2 ports.
  • Ensure the FSS-5 switch is in the 'ON' position and functioning correctly.
  • Verify that batteries are charged.
• No Signal to Servos:
  • Check connections from receivers to SERIAL RX 1 and SERIAL RX 2 ports.
  • Ensure receivers are properly bound to your transmitter.
  • Inspect S.BUS cables for damage.
• Overload Indication (Load Indicator active):
  • Reduce the current draw by checking for binding servos or other high-current components.
  • Ensure the total current draw does not exceed the unit's 30A capacity.
  • Inspect connected components for shorts or malfunctions.
• Alarm Indicator Active:
  • This indicates a detected issue. Check all connections, battery voltage, and load.
  • If the issue persists, disconnect power and re-check all components.
• Intermittent Power/Signal:
  • Check for loose connections or damaged wiring.
  • Ensure the unit is securely mounted and protected from excessive vibration.
