2. Орнотуу боюнча колдонмо
This section provides instructions for installing the P3H LCD display meter on your electric bike. Ensure your e-bike controller uses the UART2 communication protocol for compatibility.
2.1 Шайкештикти текшерүү
The P3H display operates using the UART2 communication protocol. It is crucial that your e-bike's controller also uses the UART2 protocol. If the protocols do not match, the display will not function correctly.
- Check your controller's manual or existing display for protocol information.
- Some controllers may have a label indicating the protocol (e.g., '2HAO' as shown in the image below).


2.2 Wired Installation Steps
Follow these steps for wired installation of the P3H display:
- 1-кадам: Break off the extension seat buckle and insert it from a low position.
- 2-кадам: Adjust the angle and tighten the screws to secure the display holder.
- 3-кадам: Align the position and clamp рулдагы эсептегичтин башы ордунда.
- 4-кадам: Tighten the gauge head clockwise and tighten firmly to the end.
- 5-кадам: Wrap the wire down the brake line, ensuring it is neatly routed and secured.
- 6-кадам: Install the transmitter and magnet on the front fork, aligning them correctly for speed detection.

2.3 Электр өткөргүч схемасы
The P3H display uses a 5-pin or 6-pin connection. Refer to the diagram below for the correct line sequence.



3. Иштөө нускамалары
The P3H display provides comprehensive information and control over your e-bike's functions.
3.1 Functional Interface
Дисплей төмөнкү маалыматты көрсөтөт:
- ЫЛДАМ: Current speed of the vehicle (km/h or mph).
- ЖАРДАМ БЕРҮҮ: Power assist level (0-5).
- ТӨМ: Батарея көлөмүtage.
- Пробег: Odometer (ODO) or Trip distance.
- Батарея көрсөткүчтөрү: Visual representation of battery charge.
3.2 Негизги операциялар
- Күйгүзүү/өчүрүү: Press and hold the power button (usually the middle button) to turn the display on or off.
- Changing Assist Level: Use the '+' and '-' buttons to increase or decrease the power assist level.
- Фараны башкаруу: (If supported by your controller) A short press of a specific button (often the '+' button) might toggle the headlight.
- Жүрүү режими: (If supported) A long press of the '-' button might activate walk mode.
3.3 Ылдамдык чегин жөндөө (P08 жөндөөсү)
If your display is capable of setting the speed limit (and your controller allows it), you can adjust it via the P08 setting:
- Менюга кириңиз: Long press the '+' and '-' keys simultaneously.
- P08 бөлүмүнө өтүңүз: Short press the power button to cycle through the menu options until you reach 'P08'.
- Ылдамдыкты коюу: Once in P08, use the '+' key to set your desired speed limit.
- Сактоо жана чыгуу: Жөндөөнү бүтүргөндөн кийин, жөндөөнү сактоо жана менюдан чыгуу үчүн бир убакта '+' жана '-' баскычтарын көпкө басыңыз.
Эскертүү: The default speed of the P3H display is unlimited (100). If your controller has a speed limit, the display will only show the speed up to that limit. A specially customized version may support an immediate speed limit of 25 km/h.

4. Техникалык тейлөө
To ensure the longevity and optimal performance of your Mcezdy P3H display, follow these simple maintenance guidelines:
- Тазалоо: Дисплейдин экранын жана корпусун жумшак менен сүртүңүз, damp кездеме. Экранга же экранга зыян келтириши мүмкүн болгон абразивдүү тазалоочу каражаттарды же эриткичтерди колдонуудан алыс болуңуз.asing.
- Суу таасири: While the display is IP65 waterproof, prolonged submersion or high-pressure water jets should be avoided. If it gets wet, wipe it dry as soon as possible.
- Сактагыч: When not in use for extended periods, store the e-bike in a dry, temperate environment.
- Кабелдик текшерүү: Periodically check all cables and connections for any signs of wear, fraying, or loose connections.
5. Кыйынчылыктарды
This section addresses common issues you might encounter with your P3H display.
5.1 E10 катасы көрсөтүлдү
If your instrument interface displays an 'E10' error, it typically indicates a communication failure. This can be due to two main reasons:
- Протоколдун дал келбегендиги: The communication protocol used by the display (UART2) and your e-bike's controller do not match. Ensure both devices use the UART2 protocol.
- Component Malfunction/Short Circuit: One of the e-bike's essential components (booster, rotary knob, or motor) may be malfunctioning or have a short circuit. This can prevent the controller from operating correctly and disrupt communication with the display. Inspect these components for damage.

5.2 Speed Limit Issues
- Displaying Limited Speed: If your controller has a built-in speed limit, the display will only show speed up to that limit, even if the display's internal setting is higher.
- Unable to Lift Speed Limit: If the speed limit is imposed by the controller, the display cannot override it. Only if the display itself is limiting the speed can it be adjusted via the P08 setting (see Section 3.3).
5.3 Жалпы байланыш маселелери
- Дисплей/кубат жок: Check all cable connections to ensure they are securely plugged in. Verify the e-bike's battery is charged and properly connected.
- Туура эмес окуулар: Ensure the speed sensor and magnet are correctly installed and aligned on the front fork (refer to Installation Guide).

7. Колдонуучунун кеңештери
- Verify Protocol: Always confirm your e-bike controller's communication protocol is UART2 before purchasing же шайкештик көйгөйлөрүн болтурбоо үчүн бул дисплейди орнотуңуз.
- Ылдамдыкты жөндөө: Remember that speed limits can be set by either the display or the controller. If your controller has a limit, the display cannot override it. Use the P08 setting on the display to adjust speed if the display is the limiting factor.
- E10 Ката: If you encounter an E10 error, first check for protocol mismatch, then inspect your booster, rotary knob, and motor for any faults or short circuits.
- Шайкеш келбегендиги үчүн кайтарып берүүгө болбойт: Be aware that returns or exchanges are generally not accepted for non-quality issues, especially if the problem stems from protocol incompatibility.
