4. Змесціва ўпакоўкі
The Velleman K8057 kit typically includes:
- K8057 Receiver PCB (Printed Circuit Board)
- Electronic components for assembly
- Інструкцыя па зборцы
- Кіраўніцтва карыстальніка (гэты дакумент)
Note: Transmitters (e.g., K8059, VM108, VM130T) are sold separately.
5. Настройка
5.1 Зборка
Before proceeding, ensure the K8057 kit is fully assembled according to the provided assembly instructions. Proper soldering and component placement are crucial for correct operation.
5.2 Падключэнне харчавання
Connect the appropriate DC power supply to the receiver's power input terminals. Refer to the assembly instructions for the exact voltage requirements and polarity. Incorrect power supply can damage the unit.
5.3 Output Wiring
Connect your desired devices (e.g., garage door opener, lights) to the two relay contact outputs. The relays provide potential-free contacts, allowing them to switch various loads. Ensure the load's voltage and current ratings do not exceed the relay specifications.
5.4 Learning Transmitters
To enable the receiver to respond to a transmitter, you must 'learn' its unique code:
- Press and hold the 'Learn' button on the K8057 receiver. An LED indicator will illuminate or flash.
- While holding the 'Learn' button, press a button on your compatible transmitter (e.g., K8059, VM108, VM130T).
- The LED on the receiver will change its state (e.g., flash rapidly, turn solid) to indicate successful learning.
- Адпусціце абедзве кнопкі.
- Repeat this process for any additional transmitters or buttons you wish to program, up to a maximum of 31 transmitters.
5.5 Setting Output Modes (Toggle/Pulse)
The K8057 allows you to configure each of its two outputs independently for either toggle or pulse operation. Consult the detailed assembly manual for specific jumper settings or software configuration steps to select the desired mode for each output. The pulse function may also have an adjustable switch-off timer.
5.6 Эрasing Memory
To erase all learned transmitter codes from the receiver's memory for security or reprogramming purposes:
- Пераканайцеся, што прыёмнік уключаны.
- Press and hold the 'Learn' button for an extended period (e.g., 10-15 seconds) until the LED indicator confirms the memory has been cleared (e.g., a specific flash pattern).
- Release the button. All previously learned codes are now deleted.

6. Аперацыйная
Once transmitters are learned and output modes are set, operating the K8057 is straightforward:
- Рэжым пераключэння: Pressing the corresponding transmitter button will switch the output relay ON. Pressing it again will switch the relay OFF.
- Імпульсны рэжым: Pressing the corresponding transmitter button will activate the output relay for a preset duration (the switch-off timer). The relay will then automatically switch OFF.
- Special Pulse Mode: If configured, pressing both transmitter buttons simultaneously can activate both outputs in pulse mode, useful for specific applications.
The LED indicators on the receiver will provide visual feedback on the status of the outputs and any ongoing operations.
7. Тэхнічнае абслугоўванне
- Трымайце прыёмнік чыстым і без пылу. Выкарыстоўвайце для чысткі мяккую сухую тканіну.
- Не выкарыстоўвайце вадкія ачышчальнікі або растваральнікі.
- Перыядычна правярайце ўсе злучэнні правадоў, каб пераканацца ў іх надзейнасці.
- Забяспечце, каб тэмпература і вільготнасць у рабочым асяроддзі знаходзіліся ў межах зададзеных дыяпазонаў.
8. Выпраўленне непаладак
- Receiver not responding to transmitter:
- Ensure the transmitter has fresh batteries.
- Verify the transmitter has been successfully learned by the receiver (refer to Section 5.4).
- Check the distance and any obstructions between the transmitter and receiver.
- Пераканайцеся, што прыёмнік уключаны.
- Outputs not activating:
- Check the wiring to the connected devices.
- Verify the output mode (toggle/pulse) is correctly set.
- Ensure the load connected to the relay is within its specified limits.
- Learning process fails:
- Ensure the transmitter is compatible with the K8057.
- Try clearing the receiver's memory and re-learning the transmitter.
- Ensure you are pressing the buttons correctly and within the specified time frame.
- Кароткі дыяпазон:
- Check the antenna connection on the receiver.
- Minimize sources of RF interference in the vicinity.
- Ensure the receiver is not enclosed in a metal casing that could block RF signals.
