5. Setup and Installation
5.1 Component Overview
5.2 Physical Installation
- Mounting the GEMINI 3018: Securely mount the GEMINI 3018 unit within your model. Ensure it is placed in a location that minimizes exposure to vibration and allows for good airflow.
- Vibration Damping: When the GEMINI 3018 is used in environments with strong vibrations, it is necessary to install shock-absorbing rubber fittings to protect the unit.
5.3 Battery Connections
- The GEMINI 3018 power supply is specifically designed for 7.4V (2S) lithium polymer batteries.
- Connect your two 7.4V LiPo batteries to the BATT 1 and BATT 2 ports on the GEMINI 3018. Use MPX adapters if necessary for your battery connectors.
- Ensure correct polarity when connecting batteries.
5.4 Receiver and Signal Connections
- The GEMINI 3018 supports dual receiver input for signal redundancy. Connect your primary receiver to SERIAL RX 1 and your secondary receiver to SERIAL RX 2.
- The system supports Futaba S.BUS, JETI EX.BUS, and Spektrum SRXL protocols. Ensure your receivers are configured correctly for these protocols.
- If using DUALSKY S.HUB MINI modules (included in Deluxe version), connect them to the S.BUS1/S.BUS2 servo ports or as per the S.HUB MINI instructions.
5.5 Servo and Peripheral Connections
- Connect your servos and other peripherals to the 18-channel PWM output ports.
- Utilize the 2 HPB outputs for high-power devices, each capable of delivering up to 30A.
- Ensure all connections are secure and correctly oriented.
5.6 FSS-5 Electronic Switch
- Connect the FSS-5 electronic switch to the designated 'SWITCH' port on the GEMINI 3018.
- The FSS-5 switch is a dedicated safety electronic switch with a Fail-Safe function. Any damage or disconnection of the switch will NOT cause the main unit to power off, ensuring continuous power to your model.
6. Operation
6.1 Powering On/Off
- To power on the system, ensure both batteries are connected, then activate the FSS-5 electronic switch.
- To power off, deactivate the FSS-5 switch.
6.2 Indicator Lights
The GEMINI 3018 features several indicator lights to provide system status:
- Signal Indicator: Provides comprehensive signal status.
- HV Indicator: Indicates high voltage output status.
- Load Indicator: Shows the current load status.
- Alarm Indicator: Illuminates in case of a system alarm or fault.
7. Maintenance
- Regularly inspect all wiring and connectors for signs of wear, damage, or loose connections.
- Keep the GEMINI 3018 unit clean and free from dust, dirt, and moisture.
- Ensure adequate ventilation around the unit during operation to prevent overheating.
- Periodically check battery health and charge levels.
8. Troubleshooting
- No Power: Check battery connections, ensure batteries are charged, and verify the FSS-5 switch is in the 'ON' position.
- Intermittent Power/Signal: Inspect all wiring for loose connections or damage. Ensure receivers are properly bound and configured.
- Alarm Indicator On: Refer to the specific alarm code (if available) or consult the DUALSKY support for diagnosis. This typically indicates an issue with power input, output, or internal fault.
- Servos Not Responding: Verify receiver connections, ensure the GEMINI 3018 is powered, and check individual servo connections.
9. User Tips
- Always perform a range check and functional test of all control surfaces and systems before each flight.
- Use high-quality, matched batteries for redundant power systems to ensure balanced discharge and optimal performance.
- Consider using a battery checker to monitor individual cell voltages before and after flights.
- Proper cable management is crucial to prevent interference and ensure reliable connections in complex models.
- For models with high current draw, ensure your battery connectors (e.g., MPX) are rated for the expected current.
