ATORCH GR2P Series Smart Din Rail Meter - User Manual

Product Overview

This document provides comprehensive instructions for the ATORCH GR2P series of smart din rail meters, including the GR2P (Basic), GR2PW (WiFi), and GR2PWS (WiFi Switch) models. These advanced meters are engineered to accurately measure and display critical electrical parameters for single-phase AC power systems. Key measured data includes voltage, current, power consumption, energy usage (KWh), electricity bills, and frequency. The devices also integrate control capabilities and safety protection alarm functions, making them ideal for monitoring and managing electrical loads.

The ATORCH GR2P series meters are designed for compatibility with single-phase AC power supplies operating within a voltage range of AC50~320V and a frequency of 50/60Hz, supporting current ratings up to 100A.

The user interface features a high-definition color screen that provides clear, real-time readings of essential electrical data. This includes Voltage (Vol), Current (Cur), Power (Pwr), Energy (Ene), Electricity Bill (Bill), Frequency (Fre), Power Factor (Factor), operational Run Time, and internal CPU Temperature.

Installation and Wiring

The smart din rail meter is designed for straightforward installation onto a standard C45 National standard DIN rail, which typically measures 35mm in width. This ensures secure and compliant mounting within electrical enclosures.

Wiring Connections:

• AC Output (Load): Connect the load wires to the designated L OUT and N OUT terminals on the meter.
• AC Input: Connect the incoming AC power supply wires to the L IN and N IN terminals.

The meter is equipped with an external spring mounting buckle. This feature allows for quick and secure installation, as well as easy removal, typically requiring only a screwdriver for operation.

Main Interface and Button Operation

The primary display screen of the meter presents all critical electrical parameters in an easily readable format. The device is operated via three intuitive buttons located on the front panel:

• [Power] Button: Use a short press to cycle through different display pages (page up). A long press switches between operational modes. If a numerical value is flashing, a press-and-hold action will continuously decrease the value.
• [M] Button: Serves as the primary setting and menu navigation key. A short press will flash the current setting value or allow cycling through setting options. Repeated short presses can change the position of the flashing digit. A long press will access the main settings menu or background configuration.
• [Connect] Button: A short press allows you to cycle through display pages (page down). A long press switches operational modes. When a number is flashing, a press-and-hold action will continuously increase the value.

Device Indicators:

• Power Supply Indicator: This LED illuminates to confirm that the meter is receiving normal power.
• WiFi Indicator: (Applicable only to WiFi-enabled models like GR2PW and GR2PWS) This indicator visually confirms the status of the WiFi connection. Models without WiFi functionality will not feature this indicator.

Menu and Settings Configuration

Access the advanced settings by performing a long press on the [M] button. Within the settings menu, use the [M] button to navigate between different configuration columns. When a specific numerical setting is flashing, use the [+/-] buttons to adjust it. A long press on the [+/-] buttons will confirm the adjustment or cancel the flashing number.

The following settings are accessible:

• Language: Select between Chinese and English display languages.
• Display Brightness: Adjust the brightness level of the main screen (e.g., setting 9).
• Standby Brightness: Adjust the brightness for the standby display (e.g., setting 3).
• Enter Standby Time: Configure the duration of inactivity before the meter enters standby mode (e.g., 60 seconds).
• Key Beep: Enable or disable audible feedback for button presses.
• Price: Input the electricity tariff rate per unit (e.g., per KWh) for accurate bill calculation.
• Over-Voltage (OVP) Threshold: Set the maximum permissible voltage. If this limit is exceeded, an alarm will trigger, and the output may be cut off (depending on the model). Example: 265.0V.
• Over-Current (OCP) Threshold: Set the maximum permissible current. Exceeding this limit triggers an alarm and potential output cutoff. Example: 100.0A.
• Over-Power Threshold: Set the maximum permissible power. Exceeding this limit triggers an alarm and potential output cutoff. Example: 26500W.
• Under-Voltage Threshold: Set the minimum permissible voltage. Falling below this limit triggers an alarm and potential output cutoff. Example: 075.0V.
• Switching Model: Select the operational mode or control type (e.g., 'Controlled').
• Standby Screen: Choose the display content for the standby mode (e.g., 'Measurement' for large number display).
• Wi-Fi Device Reset: Utility to reset and reconfigure WiFi network connection settings.
• Date Zero: Function to reset the internal date and time settings.
• System All Default Setting: Resets all user-configured settings and parameters back to their original factory defaults.

Important Notes on Settings:

• Protection thresholds (Over-Voltage, Over-Current, Under-Voltage) are critical safety features. When these thresholds are met or exceeded, an alarm interface will appear. For models equipped with a relay, the output will be automatically disconnected to prevent damage or hazards.
• The standby screen can be configured for a simplified measurement view, displaying large numerical values for quick status checks after a period of inactivity.
• To clear accumulated historical data, such as total energy consumption or electricity bills, navigate to the relevant setting and press the [+] button. The system will prompt with "OK" to confirm the data erasure.
• If you change your WiFi network name (SSID) or password, you must use the 'Wi-Fi Device Reset' option to re-establish the connection.
• To restore the meter to its original factory state, navigate to 'System All Default Setting', then perform a long press (approximately 3 seconds) on the [+] button.

Alarm Functions and Protection

The ATORCH GR2P series offers different levels of alarm and protection features depending on the model:

• Basic version (GR2P): This model provides alarm notifications when abnormal conditions are detected but does not automatically cut off power. It does not support WiFi connectivity.
• WiFi version (GR2PW): Offers alarm notifications and supports remote configuration and reminders via the WiFi connection. Similar to the basic version, it does not interrupt power supply during alarms.
• WiFi Switch Version (GR2PWS): This advanced model includes all WiFi features, provides alarm notifications, and crucially, can automatically cut off the power supply when protection thresholds are breached.

Note: The automatic power cut-off functionality is exclusively available on the GR2PWS model and requires the companion mobile application for operation. The GR2P and GR2PW versions lack this specific power-interrupting capability.

App Control and Connectivity

The WiFi-enabled versions of the ATORCH GR2P series meters (GR2PW and GR2PWS) offer advanced remote monitoring and control capabilities through dedicated mobile applications. Users can leverage either the "Smart Life" or "Tuya" applications for seamless integration with their smart home ecosystems.

Getting Started with App Control:

1. Download the App: Obtain the "Smart Life" or "Tuya" application from your mobile device's official app store. Compatibility is ensured for Android devices running version 5.0 and above, and iOS devices running version 8.0 and above.
2. Network Requirements: Ensure your mobile device is connected to a 2.4GHz WiFi network, as the meter operates on this frequency band.
3. Enable Permissions: For initial device discovery and setup, it is crucial to enable Bluetooth and GPS location services on your mobile device.
4. Device Configuration: Launch the downloaded application and follow the on-screen prompts to add and configure your ATORCH smart meter. The app guides you through the connection process step-by-step.

Once connected, the mobile application provides a comprehensive suite of features, including real-time data visualization, historical trend graphs for voltage, current, and power, the ability to schedule device operations, and management of prepayment electricity features. The app also allows for remote control of the meter's functions.

Important Note: If the GR2P_BLE model fails to appear in the app after initiating the Bluetooth scan, please verify that your mobile phone's settings grant the application necessary permissions for storage and location access. Enabling these permissions is essential for correct model detection.
