2. Technical Specifications

3. Installation & Initial Setup

3.1 Physical Installation

The controller supports multiple installation methods:

• DIN35mm Rail Installation: Mount the device onto a standard DIN35mm rail.
• Screw Installation: Secure the device using screws. The mounting dimensions are 115mm x 90mm.

3.2 SIM Card Insertion

1. Ensure the controller is powered off before inserting the SIM card.
2. If your Micro SIM card has a PIN code, please disable it using a mobile phone before inserting it into the controller.
3. Locate the Micro SIM card slot on the device.
4. Insert the SIM card into the slot until you hear a 'ticking' sound, indicating it is securely in place.
5. To remove the SIM card, push it in again until it 'pops out'.

3.3 Power On

Connect a DC 12V power adapter to the DC power input port (7-36V DC compatible). Ensure the power supply is stable.

3.4 Connecting to the 4G Network

After powering on, observe the SIG indicator:

• If the SIG LED flashes once per second, it indicates connection to the GSM network.
• If the SIG LED flashes once every two seconds, it means the device is successfully connected to the 4G network.
• If the SIG LED remains constantly on, it indicates no access to the network. In this case, check the SIM card installation, antenna connection, and ensure the SIM service is active and has data. You may need to configure APN settings (see Troubleshooting).

4. Operation Modes

4.1 SMS Control

The controller can be managed via SMS commands. SMS control is not limited to authorized mobile phone numbers if the password is correct; any SMS command can enter the device.

Note: RLO (feedback SMS when input action) is only valid after APP input control is set and push is activated.

4.2 APP Control (WLTE Control)

The WLTE Control app provides a convenient, intelligent, and handy way to manage your device. The app communicates with the controller via 4G internet access.

4.2.1 App Download

The app is named "WLTE Control".

• Android: Search for "WLTE Control" in the Google Play Store or use the following link: Google Play Store
• iPhone: Search for "WLTE Control" in the Apple App Store or use the following link: Apple App Store
• Alternatively, you can download the app via the usage guide link: APP Usage Guide

4.2.2 Adding Devices to the App

The default password for adding devices to the app is 1234.

4.3 Web Control

Centralized control of equipment is possible via a web browser on a PC.

4.4 Temperature Linkage

The controller can monitor real-time temperature. When the temperature reaches a preset value, it can trigger the relay switch (on/off) and send temperature alarm messages (SMS/APP/Email).

4.5 Timing Control

Set up to 24 groups of timing controls to automate equipment operation (e.g., turn on/off at specific times daily or on certain days).

4.6 Short-time Trigger (Inching)

This function allows for a short-duration relay activation (1 to 9 seconds settable), suitable for applications like controlling electric gates or garage doors.

4.7 Power Failure Alarm (DL2-WLTE-TVC only)

The DL2-WLTE-TVC version includes a power failure alert function. Upon power failure or restoration, you can receive an SMS/APP/Email alert.

5. Wiring Instructions

Refer to the following diagrams for connecting the controller to various devices. Always ensure power is disconnected before performing any wiring.

• Low Power Lamp or Home Appliance (AC 220V): Connect the lamp/appliance to the relay's COM and NO terminals, with the AC 220V power supply.
• DC Motor or Equipment Application (DC 12-120V): Connect the DC motor/equipment to the relay's COM and NO terminals, with the DC 12-120V power supply.
• High-Power AC Motor/Equipment Application (AC 220/380V): For high-power AC loads, use an AC contactor. The controller's relay output (COM, NO) triggers the AC contactor, which then controls the high-power AC motor.
• Trigger to Control Electronic Lock: Connect the electronic lock to the relay's COM and NO terminals. The relay acts as a switch to open/close the lock.
• DC Motor Forward and Reverse Control: This requires two relays. One relay controls forward rotation (Channel 1 ON, Channel 2 OFF), and the other controls reverse rotation (Channel 1 OFF, Channel 2 ON). Ensure the power of the DC motor is less than 80W.
• Three-Phase Motor Forward and Reverse Control (380V): This setup requires two AC contactors for controlling the forward and reverse rotation of a three-phase AC motor. The controller's relays activate the respective contactors.

6. Troubleshooting

6.1 Network Connection Issues

If the SIG LED is constantly on, indicating no network access:

1. Verify that the Micro SIM card is correctly inserted and activated with a data plan.
2. Ensure the antenna is securely connected.
3. Check the APN settings. The default APN is "internet" with empty username and password. If this doesn't match your country's provider, you need to set it manually via SMS.

How to set APN via SMS:

Command format: SN+password+APN+length of APN=APN content, length of user=user content, password length =password content

Example: For APN: datelo.com.br, user: algar, password: 12345, send: SN0000APN13=datelo.com.br,05=algar,05=12345

To set parameters to null (empty), use 00=0. Example: SN0000APN05=cmnet,00=0,00=0

6.2 SMS Feedback Issues (KT Command)

If you are not receiving SMS feedback in certain situations, the KT mode might be closed. Try setting KT mode:

Command format: SN+password+KT+length of country code+S+country code+L+length of number

Example (France, country code 33, number length 9): SN0000KT2S33L09

To close KT mode, send: SN0000KTC

6.3 App Connection Issues

Ensure the device is successfully connected to the 4G network (SIG LED flashing once every two seconds). If not, resolve network issues first.

7. Maintenance

• Keep the device in a dry, clean environment, away from direct sunlight and extreme temperatures.
• Avoid exposing the device to water or excessive moisture.
• Clean the exterior of the device with a soft, dry cloth. Do not use harsh chemicals or solvents.
• Ensure all connections (power, antenna, SIM card, relay outputs) are secure and free from corrosion.

8. Warranty & Support

Most products from this store come with a 1-year warranty.

9. Important Notes

• The DL2-WLTE-T version does NOT include the power failure alarm function. This feature is exclusive to the DL2-WLTE-TVC model.
• Always disconnect power before performing any wiring or SIM card insertion/removal.
• Ensure your Micro SIM card has no PIN code enabled before insertion.
• For optimal performance, ensure a strong 4G signal in the installation area.
