DUALR3 Lite vs. DUALR3 (Standard)

It is important to note the differences between the DUALR3 Lite and the standard DUALR3 module:

Note: The DUALR3 Lite does not support power metering or overload protection features found in the standard DUALR3.

5. Монтаж

Before proceeding with installation, ensure the power is OFF at the main circuit breaker to prevent electric shock. All wiring should be performed by a qualified electrician.

5.1 Інструкції з підключення

Важливо: Do not pull the wire directly from the live wire to the S1/S2 external switch. All connections to S1/S2 must originate from the DUALR3 Lite device itself.

Motor Mode Wiring (e.g., for Roller Shutters)

This mode is suitable for four-wire tubular motors. Connect the motor to the L Out 1 and L Out 2 terminals for forward and reverse operation. External momentary switches can be connected to S1 and S2 for manual control.

Image: AC Motor Wiring Demo for Motor Mode with momentary switches.

For dual relay momentary switch or 3-gang rocker switch configurations, refer to the detailed diagrams in the eWeLink app or the full PDF manual for specific wiring instructions.

Switch Mode Wiring (e.g., for Lights)

In Switch Mode, the DUALR3 Lite controls two output loads independently. You can connect existing physical switches (momentary, rocker, or ON/OFF) to S1 and S2 to retain manual control alongside app control.

Image: Compatible switch types for lights and roller shutters.

For double two-way control using SPDT switches, refer to the detailed diagrams in the eWeLink app or the full PDF manual.

Dry Contact Sensor Wiring (Follow Mode)

The DUALR3 Lite can also be used in Follow Mode with dry contact sensors. This allows the device to respond to signals from external sensors.

Image: Wiring for dry contact sensors in Follow Mode.

Ensure the neutral wire and live wire connections are correct. The device can still function if no physical light switch is connected to S1/S2. If S1/S2 are connected to physical switches, the corresponding working mode must be selected in the eWeLink APP.

5.2 Монтаж

The DUALR3 Lite is designed for flush-mounted installation, typically behind a standard wall switch or within a junction box. It also features a detachable mounting base for DIN-Rail installation.

• Вага пристрою менше 1 кг.
• An installation height of less than 2 meters is recommended.

9. Вирішення проблем

9.1 Fail to Pair Wi-Fi Devices with eWeLink App

1. Режим сполучення: Ensure the device is in pairing mode (Wi-Fi LED indicator flashes two short, one long). The device automatically exits pairing mode if not paired within 3 minutes.
2. Служби визначення місцезнаходження: Turn on location services on your mobile phone and grant permission to the eWeLink app. Location information is used to obtain Wi-Fi list details.
3. Діапазон Wi-Fi: Make sure your Wi-Fi network operates on the 2.4GHz band.
4. SSID & Password: Verify that you have entered the correct Wi-Fi SSID and password. Avoid special characters. Incorrect passwords are a common cause of pairing failure.
5. Близькість до роутера: During pairing, keep the device close to the router for optimal signal transmission.
6. Сумісний режим: If standard Bluetooth pairing fails, try pairing using the Compatible Mode (refer to Section 6.4).

9.2 Wi-Fi Devices "Offline" Issues

If the Wi-Fi LED indicator blinks once every 2 seconds, it means the device failed to connect to the router. Check the following:

• Incorrect SSID/Password: Double-check your Wi-Fi SSID and password. Ensure no special characters (e.g., Hebrew, Arabic) are used, as the system may not recognize them.
• Router Capacity: Your router might have a low carrying capacity. If the number of connected devices exceeds the maximum, remove some devices or upgrade your router.
• Потужність сигналу: The Wi-Fi signal might be weak due to distance from the router or obstacles. Move the device closer or remove obstructions.
• Управління MAC: Ensure the device's MAC address is not blacklisted in your router's MAC management settings.

If the Wi-Fi LED indicator flashes twice repeatedly, it means the device connected to the router but failed to connect to the server. Check the following:

• Підключення до Інтернету: Verify your internet connection is working normally (e.g., by browsing on your phone or PC).
• Router Capacity: As above, check if your router's capacity is exceeded.
• ISP Blocking: Contact your Internet Service Provider (ISP) to confirm that the eWeLink server addresses are not being blocked.

If these steps do not resolve the issue, submit your problem via the "Help & Feedback" section in the eWeLink App.

10. Поради користувача

• Version Clarity: Always confirm you are using the DUALR3 Lite model, as it has specific feature limitations compared to the standard DUALR3, particularly regarding power metering and overload protection.
• Вимірювання потужності: The DUALR3 Lite does NOT include power metering functionality. If this feature is essential for your application, consider the standard DUALR3 model.
