1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the Yaesu G-5500 Azimuth-Elevation Rotator. The G-5500 is designed for precise control of satellite antennas, allowing for simultaneous adjustment of both azimuth (horizontal direction) and elevation (vertical angle).
The system consists of a robust rotator unit and a dual-meter control box, enabling accurate tracking of orbiting satellites. Please read this manual thoroughly before attempting installation or operation to ensure safe and correct usage.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in injury, equipment damage, or electric shock.
- Always disconnect power to the rotator and control unit before performing any installation, maintenance, or troubleshooting.
- Ensure all electrical connections are secure and properly insulated to prevent short circuits and electrical hazards.
- Antenna installation should be performed by qualified personnel, adhering to local building codes and safety regulations.
- Avoid installing antennas near power lines. Contact with power lines can be fatal.
- Use appropriate lifting equipment and safety gear when working at heights.
- The rotator unit is designed for outdoor use, but the control box must be installed indoors in a dry environment.
- Verify the correct operating voltage (117V or 220V) before connecting the control box to a power source.
3. Setup and Installation
Proper setup is crucial for the optimal performance and longevity of your G-5500 rotator system.
3.1 Unpacking and Inspection
Carefully unpack all components. Verify that all parts are present and undamaged. The package includes the rotator unit, the control box, and two sets of rotator plugs for cable assembly. Cables are not included.
3.2 Cable Requirements
The G-5500 requires two runs of 6-conductor cables to connect the rotator unit to the control box. These cables are not supplied and must be sourced separately. UTP (Unshielded Twisted Pair) cable, commonly used in LAN connections, is suitable for this purpose. Ensure the cables are of sufficient gauge and quality for the intended length and outdoor exposure.
3.3 Rotator Unit Mounting
The rotator unit should be securely mounted to a mast or tower capable of supporting the combined weight and wind load of the rotator and antenna. The G-5500 is designed to handle wind loads up to 1 square meter (10 square feet).
- Ensure the mast size is within the specified range of 38mm to 62mm diameter.
- Mount the rotator unit in a position that allows for unobstructed rotation and elevation movement of the antenna.
- Secure all mounting hardware tightly to prevent slippage or instability.
3.4 Electrical Connections
Use the provided rotator plugs to assemble your control cables. Connect one end of each 6-conductor cable to the rotator unit and the other end to the corresponding ports on the rear of the control box. Pay close attention to the wiring diagram provided in the full product manual (not included here) to ensure correct pin assignments for azimuth and elevation control and feedback.
The G-5500 is wired for either 117V or 220V operation. Confirm your unit's voltage requirement before connecting the control box to a power outlet.
Figure 1: Yaesu G-5500 Azimuth-Elevation Rotator unit (left) and Control Box (right). The rotator unit connects to the control box via two 6-conductor cables (not shown). The control box features dual meters for elevation and azimuth, along with directional control switches and a power switch.
4. Operating Instructions
Once the G-5500 system is installed and connected, follow these steps for operation:
4.1 Powering On
Connect the control box to the appropriate 117V or 220V AC power outlet. Press the red "POWER" switch on the front panel of the control box to turn the unit on. The meters should illuminate or become active.
4.2 Azimuth Control
The right-hand meter displays the current azimuth position of the antenna (0-360 degrees). Use the "LEFT (CCW)" and "RIGHT (CW)" switches to rotate the antenna horizontally. Hold the switch down until the desired azimuth is reached. Release the switch to stop rotation.
4.3 Elevation Control
The left-hand meter displays the current elevation angle of the antenna. Use the "DOWN" and "UP" switches to adjust the antenna's vertical angle. Hold the switch down until the desired elevation is reached. Release the switch to stop movement.
4.4 Satellite Tracking
For satellite tracking, simultaneously adjust both azimuth and elevation controls to follow the satellite's path. Practice smooth and coordinated movements to maintain optimal signal reception.
5. Maintenance
Regular maintenance ensures reliable performance of your G-5500 rotator.
- Cable Inspection: Periodically inspect all control cables for signs of wear, damage, or degradation, especially where exposed to weather. Replace damaged cables promptly.
- Connection Check: Ensure all electrical connections remain tight and free from corrosion.
- Mounting Hardware: Check mounting bolts and clamps on the mast for tightness. Re-tighten if necessary.
- Lubrication: Refer to the full service manual for specific lubrication requirements, if any. Generally, the rotator unit is designed for minimal user lubrication.
- Environmental Protection: While the rotator unit is weather-resistant, extreme weather conditions (heavy ice, strong winds) can impact performance. Consider protective measures if operating in such environments.
6. Troubleshooting
This section addresses common issues you might encounter with your G-5500 rotator.
| Problem | Possible Cause | Solution |
|---|---|---|
| Rotator does not move. | No power to control box; loose cable connections; internal fuse blown; motor failure. | Check power supply and power switch. Verify all cable connections. Inspect internal fuses (refer to full manual). If motor failure is suspected, contact authorized service. |
| Meters show incorrect readings. | Incorrect cable wiring; faulty feedback potentiometer; calibration issue. | Review wiring diagram and re-check connections. If problem persists, professional service may be required for potentiometer or calibration. |
| Rotator moves intermittently or sluggishly. | Loose connections; insufficient power; excessive load on antenna; internal mechanical issue. | Check all cable connections. Ensure power supply is stable. Verify antenna load is within specifications. If mechanical issue, contact authorized service. |
For complex issues or internal repairs, it is recommended to contact an authorized Yaesu service center.
