The GEYA GRT8-TS Bluetooth time control relay is a versatile device designed for precise timing control in various industrial and domestic applications. This instruction manual provides a comprehensive overview of its functions, features, and operational guidelines.
The GRT8-TS relay serves as a programmable timer that can control the switching on and off of electrical loads at predetermined times. Its primary function is to automate the operation of equipment, contributing to energy efficiency and operational convenience. The device is particularly well-suited for applications requiring regular, scheduled activation and deactivation of systems.
The core functionality of the GRT8-TS lies in its ability to receive timing instructions via Bluetooth connectivity from a mobile phone application. This modern approach to programming eliminates the need for complex manual adjustments on the device itself, making it user-friendly and highly adaptable. Once programmed, the relay operates autonomously, executing the scheduled tasks with precision.
The relay supports multiple timing settings, allowing for intricate schedules to be established. For instance, the GRT8-TS1 model offers 8 ON/8 OFF timing groups, while the GRT8-TS2 provides 2x8 ON/2x8 OFF groups, catering to different levels of complexity in scheduling. This flexibility makes it suitable for a wide array of applications, from simple daily on/off cycles to more complex weekly or seasonal programs.
Furthermore, the GRT8-TS incorporates two distinct working modes: automatic and manual. In automatic mode, the relay adheres strictly to the programmed schedule. The manual mode, on the other hand, allows for immediate override of the programmed settings, providing flexibility for situations that require temporary deviations from the schedule. This dual-mode functionality ensures that users have both automated reliability and immediate control when needed.
The device is also equipped with visual indicators to provide real-time feedback on its operational status. A green LED indicator, labeled "Un," signifies the power status of the relay. When the device is powered on, this indicator remains steadily lit. If the panel key is pressed, the green indicator will flash, confirming user interaction. A red LED indicator, labeled "R," communicates the relay's output status, indicating whether the connected load is currently active or inactive. This visual feedback is crucial for quick diagnostics and operational verification without needing to consult the mobile application.
The GRT8-TS is designed with ease of use as a paramount feature, primarily through its Bluetooth connectivity and intuitive mobile application. The setup process begins by ensuring that Bluetooth is enabled on the mobile phone. Users then scan a provided QR code or enter a specific URL into a mobile browser to download the dedicated application. This streamlined approach to software acquisition ensures that users can quickly get started with programming their relay.
Once the application is installed, users can open it and follow the on-screen prompts to set the timer. The application interface is designed to be user-friendly, simplifying the process of creating and managing timing schedules. For those who require more detailed guidance, a comprehensive app operation manual is available from the after-sales department, ensuring that users can fully leverage all the features of the application.
A key operational feature is the ability to calibrate the time automatically. If the red and green indicators flash simultaneously, it signals that the relay's internal clock needs synchronization. Reconnecting the relay with the app will automatically calibrate the time, ensuring accurate scheduling. This self-correction mechanism enhances the reliability of the device.
For scenarios involving multiple GRT8-TS relays, the mobile application facilitates efficient management. When multiple relays need to be configured simultaneously, the app can search for and display them in an equipment list. To identify a specific relay for programming, users can press and hold the relay panel button for three seconds. This action will temporarily add a "wait setting" word next to the relay's name in the app, indicating that it is ready for configuration. After two minutes, the equipment name reverts to normal, maintaining a clean interface. This feature is particularly useful in installations with numerous timing devices, allowing for organized and targeted programming.
The device also includes a factory reset option, which is valuable for troubleshooting or reconfiguring the relay from scratch. If users forget the entry password or wish to restore all settings to their default state, they can press and hold the panel button for ten seconds. This action initiates a factory reset, clearing all programmed schedules and passwords, and returning the device to its original settings.
The GRT8-TS is designed for DIN rail mounting, specifically adhering to EN/IEC 60715 standards. This standard mounting method ensures compatibility with common electrical enclosures and facilitates organized installation within control panels. The compact 1-MODULE design further contributes to space efficiency, making it suitable for installations where panel space is at a premium.
The wide operating voltage range of AC/DC 24-240V makes the GRT8-TS highly adaptable to various power supply configurations, enhancing its versatility across different applications and geographical regions. This broad compatibility simplifies inventory management and reduces the need for specialized versions of the relay.
The GRT8-TS is engineered for reliability and minimal maintenance, reflecting its industrial application suitability. The robust construction and adherence to international standards like GB/T14048.5, IEC60947-5-1, and EN 61812-1 underscore its durability and long operational life. These standards ensure that the device can withstand typical operating conditions without frequent failures.
The visual LED indicators play a crucial role in maintenance by providing immediate status updates. The green "Un" LED confirms power supply, while the red "R" LED indicates output status. Any deviation from expected behavior, such as the simultaneous flashing of both LEDs, signals a need for time calibration, which is easily resolved via the mobile app. This immediate visual feedback helps in quickly identifying and addressing minor operational issues without complex diagnostic tools.
The device's design for DIN rail mounting not only aids in initial installation but also simplifies any future maintenance or replacement. The modular nature allows for easy removal and re-installation of the unit without disturbing adjacent components in a control panel. This "plug-and-play" aspect minimizes downtime during servicing.
The mobile application itself contributes to maintenance by offering a centralized platform for monitoring and managing the relays. While not explicitly a diagnostic tool, the ability to view the relay's working state and confirm its automatic operation mode helps in verifying correct functionality. Should a relay not be operating as expected, the app provides the interface to re-program or reset it, often resolving issues remotely.
The factory reset function, accessible by holding the panel button for ten seconds, is a powerful maintenance feature. It allows for a complete system refresh, which can resolve software glitches or configuration errors that might accumulate over time. This ensures that the relay can always be returned to a known, stable state, extending its useful life and simplifying troubleshooting.
The GRT8-TS is designed to operate within a wide temperature range, from -20°C to +55°C, and can be stored in temperatures ranging from -35°C to +75°C. This resilience to environmental variations reduces the likelihood of temperature-related failures, contributing to its overall reliability and reducing maintenance needs in diverse operational environments.
Finally, the instruction manual emphasizes the importance of professional installation. It states that "The products must be installed by qualified electricians. All and any electrical connections of the product shall comply with the appropriate safety standards." This highlights a key aspect of maintenance: proper initial installation by trained personnel significantly reduces the risk of future malfunctions and ensures the long-term reliability and safety of the device. Adherence to WEEE regulations for disposal also underscores a commitment to responsible end-of-life management, although this is not a direct maintenance feature of the device itself.
