Schartec YET402PC-V2.0 - User Manual

This document describes an external wireless receiver, model YET402PC-V2.0, designed for controlling various systems, likely garage doors or gates, via remote controls. The receiver acts as an interface, receiving signals from hand transmitters and translating them into actions through its relay outputs.

Function Description

The primary function of this external wireless receiver is to enable wireless control of a connected system. It features two independent relay outputs, labeled CH1 and CH2, allowing it to control two distinct functions or devices. For instance, CH1 could operate a main gate, while CH2 could control a pedestrian gate or a separate lighting system. The receiver is designed to store up to 400 different remote control codes, providing ample capacity for multiple users or various control scenarios.

The device operates by receiving radio frequency signals from compatible hand transmitters. Once a signal is received and recognized, the corresponding relay output is activated. This activation typically involves a momentary closure of the relay contacts, which then triggers the connected system (e.g., opening or closing a gate motor). The receiver includes dedicated "Learn" buttons (Learn 1 and Learn 2) for each channel, simplifying the process of pairing new remote controls. An integrated LED (Learn-LED) provides visual feedback during the programming and erasing processes, indicating the status of the learning mode.

Power is supplied to the receiver via a 12-24 V DC input, making it compatible with a wide range of existing control systems. It also includes terminals for connecting an external antenna, which can be crucial for optimizing signal reception, especially in environments with potential interference or over longer distances. The clear labeling of terminals (ANT, CH1, CH2, V+, GND) ensures straightforward installation and wiring.

Usage Features

The receiver offers user-friendly features for programming and managing remote controls.

Programming Remote Controls: To program a new remote control, the user initiates a learning sequence for the desired channel. This involves pressing and holding the respective "Learn" button (Learn 1 for CH1 or Learn 2 for CH2) for approximately one second. Upon activation, the "Learn-LED" for that channel will illuminate, indicating that the receiver is in learning mode. The user then needs to press and hold the desired button on the hand transmitter. The "Learn-LED" will first blink, confirming that a signal has been received, and then extinguish, signaling that the remote control has been successfully learned to that specific channel. This process can be repeated for each additional hand transmitter that needs to be paired with the receiver, ensuring that multiple users can operate the connected system. The ability to program up to 400 remote controls makes it suitable for residential, commercial, or multi-user applications.

Controlling Outputs: Once a remote control is programmed, pressing the corresponding button on the hand transmitter will activate the associated relay output on the receiver. For example, if a remote control button is programmed to CH1, pressing that button will momentarily close the CH1 relay, triggering the connected device. The two independent channels allow for versatile control, enabling users to manage two separate functions with a single receiver.

Maintenance Features

While the document does not detail specific routine maintenance procedures, it provides crucial information regarding setup and troubleshooting that can be considered part of maintaining optimal performance.

Erasing Encoded Remote Controls: Should there be a need to remove all programmed remote controls from a specific channel, the receiver offers a simple erase function. To delete all encodings for a channel, the user must press and hold the respective "Learn" button (Learn 1 or Learn 2) until the "Learn-LED" for that channel extinguishes. This action completely clears the memory for that channel, ensuring that previously programmed remote controls no longer operate the connected system. This feature is particularly useful for security purposes, such as when a remote control is lost or when access needs to be revoked for certain users.

Installation Considerations for Optimal Performance: The manual includes a significant caution regarding the installation location of the receiver. To prevent potential interference and ensure reliable operation, it is strongly advised not to install the radio receiver in the immediate vicinity of the control unit of the connected system. This recommendation is a key maintenance-related guideline, as proper installation directly impacts the receiver's performance and longevity. Avoiding electromagnetic interference from other electronic components helps maintain signal integrity and prevents erratic behavior or communication failures. Ensuring a clear line of sight or an optimal placement for the external antenna can also contribute to better signal reception and overall system reliability.

Compliance and Documentation: The declaration of conformity (CE) indicates that the device meets applicable European and national guidelines. This compliance is supported by declarations, certificates, test reports, and documents held by the manufacturer. While not a direct maintenance feature, the availability of this documentation ensures that the device adheres to safety and performance standards, indirectly contributing to its reliability and reducing the likelihood of issues that might require maintenance. Users can request these documents if needed, providing transparency and assurance regarding the product's quality and regulatory adherence.

Safety Information: The manual also includes important safety instructions, such as keeping remote controls out of the hands of children and ensuring that only authorized and instructed persons operate them, always in sight of the door or gate. These guidelines, while primarily for user safety, also contribute to the safe and proper operation of the device, preventing misuse that could lead to damage or malfunctions.

Environmental Disposal Information: Finally, the document provides crucial information regarding the environmental disposal of electronic devices and batteries. It states that these items must not be disposed of as household waste but should be taken to designated acceptance and collection points. This information, while related to the end-of-life of the product, is an important aspect of responsible ownership and environmental maintenance, ensuring that the device's components are recycled properly.
