Kandungan Pakej
Sila sahkan bahawa semua komponen ada sebelum meneruskan pemasangan:
- Orion 7829 EQ-3M Single-Axis Motor Unit
- Pengawal Tangan
- Battery Case (requires four D-cell batteries, not included)
- Hex keys for installation
Persediaan
1. Pemasangan Bateri
- Buka casing bateri.
- Insert four D-cell batteries (not included) into the battery case, ensuring correct polarity.
- Tutup bekas bateri dengan selamat.
2. Memasang Unit Motor
- Locate the Right Ascension (RA) fine tuner shaft on your AstroView equatorial mount.
- Slide the hollow cylinder of the motor unit over the RA fine tuner post.
- Align the small hex nut on the motor unit's cylinder with the groove on the RA fine tuner post.
- Tighten the hex nut using the provided hex key to couple the motor drive to the RA fine tuner. Ensure it is snug to prevent slipping, but do not overtighten.
- Attach the motor unit to the mount using the designated attachment points and hex key.
3. Connecting the Hand Controller and Battery Case
- Connect the cable from the motor unit to the designated port on the hand controller.
- Connect the cable from the battery case to the designated power input on the hand controller.
- Pastikan semua sambungan selamat.
4. Initial Checks and Polar Alignment
- Sebelum ini viewing, ensure the N/S switch on the hand controller is set to the correct hemisphere (e.g., "N" for Northern Hemisphere). This switch can be easily bumped, so always verify its position.
- For effective tracking, your equatorial mount must be properly polar aligned. Refer to your telescope mount's manual for detailed polar alignment procedures. A more accurate polar alignment will result in better tracking performance.
- Ensure the RA fine tuner is positioned to allow for full range of motion before starting your viewing session. If the RA fine tuner reaches its limit, you will need to manually reset it.
Arahan Operasi
1. Powering On and Sidereal Tracking
Once the motor unit, hand controller, and battery case are connected, and batteries are installed, the drive is ready for operation. The motor will begin tracking at the sidereal rate automatically when powered on, assuming the N/S switch is correctly set.
2. Using the Hand Controller
The hand controller allows for precise adjustments to the tracking speed:
- 2x Speed: Press the 2x button to temporarily increase or decrease the tracking speed by a factor of two. This is useful for centering objects in the eyepiece.
- 8x Speed: Press the 8x button for faster adjustments, increasing atau decreasing the tracking speed by a factor of eight. Use this for larger positional changes.
- Mod Jeda: The controller may include a pause function to temporarily stop tracking without powering down the unit.
- Kawalan Arah: Use the directional buttons (often labeled + and - or arrows) in conjunction with the 2x or 8x speed buttons to move the telescope east or west in Right Ascension.
When making adjustments, especially with the 8x speed, be aware that there might be a slight lag or overshoot when releasing the button. With practice, you will develop a feel for these minor characteristics.
3. Clutch Mechanism
The motor unit features a spring-loaded clutch. This allows for quick disengagement of the motor, enabling manual coarse adjustments to the Right Ascension via the mount's control knob. To re-engage, simply release the clutch. Ensure the thumb screw on the mount shaft is kept as loose as possible while maintaining functionality to prevent gear slipping.
Penyelenggaraan
Pengurusan Bateri
The drive operates on four D-cell batteries. Battery life can vary, but expect approximately 2-2.5 hours of continuous use before performance may degrade. It is highly recommended to use rechargeable D-cell batteries and to carry spare charged batteries for extended viewing sessions. Low battery power can cause timing inaccuracies and lag.
Penjagaan Am
- Keep the motor unit and controller clean and free from dust and moisture.
- Store the unit in a dry, temperate environment when not in use.
- Avoid dropping or subjecting the unit to harsh impacts.
Menyelesaikan masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Motor not tracking or moving |
|
|
| Drive gear slips |
|
|
| Inaccurate tracking or object drifts out of view dengan cepat |
|
|
| Lag or overshoot when using 2x/8x speed buttons | Normal operational characteristic. | Practice using the speed controls to develop a feel for the response time. Approach targets from the positive direction to minimize overshoot. |
| RA fine tuner reaches limit | The RA worm gear has reached its end of travel. | Manually reset the RA fine tuner to its central position before starting a viewing session. This may require temporarily disengaging the motor. |
