3. Setup

3.1 Unpacking and Inspection

Before installation, carefully unpack the device and inspect for any signs of damage. Ensure all components are present:

• DL1-WLTE-T/TVC Controller
• Antenna
• DC12V Power Adapter (if included with your version)
• USB Cable (for certain configurations/updates, if included)

3.2 SIM Card Installation

1. Ensure the controller is powered off.
2. Locate the Micro SIM card slot on the device.
3. Insert a local 4G LTE Micro SIM card into the slot. Ensure it is correctly oriented and securely seated.

3.3 Antenna Connection

Screw the provided antenna onto the SMA interface connector labeled "ANT" on the controller.

3.4 Mounting the Controller

The controller supports two installation methods:

• DIN35mm Rail Installation: Attach the controller to a standard DIN35mm industrial rail.
• Screw Installation: Use screws to mount the controller to a flat surface. Refer to the diagram for screw hole locations and dimensions (115mm x 90mm).

3.5 Wiring Connections

Connect your equipment to the relay output terminals (COM, NO, NC) and provide DC power to the device. Ensure all connections are secure and follow local electrical codes. The relay output is rated for 30A/30VDC, 30A/250VAC, and 30A/125VAC.

Power Input: DC 7-36V (Standard adapter DC12V 1A recommended).

Below are common wiring examples:

• Low Power Lamp or Home Appliance: Direct connection to AC 220V.
• DC Motor or Equipment: Direct connection to DC 12/24V.
• High-power AC Motor/Equipment: Requires an external AC contactor for AC 220/380V applications.
• Trigger to Control Electronic Lock: Connect the switch and electronic lock as shown.

Temperature Sensor: Connect the temperature sensor to the designated sensor port. The device supports 1 sensor port with a detection range of -40℃ to 120℃.

Input Interface: The device has 2 input interfaces (GND, 1, 2) for external triggers or monitoring.

4. Operating Instructions

The DL1-WLTE-T controller offers several methods for remote operation.

4.1 Dial Control

You can control the device by making a phone call to the SIM card number inserted in the controller. The device will recognize authorized numbers and execute commands (e.g., toggle relay state).

4.2 SMS Control

Send specific SMS commands to the controller's SIM card number to control connected equipment. The device will respond with status messages.

4.3 Mobile App Control (WLTE Control)

Download and install the "WLTE Control" app on your smartphone for convenient and intelligent control. The app allows for device management, sensor monitoring, timing settings, and receiving notifications.

• Function 1: 30A Relay Output: Directly drive AC motors below 3KW.
• Function 2: Temperature Control: Monitor real-time temperature. Trigger relay switch and send alarm messages when temperature exceeds set limits.
• Function 3: Time Control: Set up to 24 groups of timing schedules for daily or specific day operations.
• Function 4 (TVC Version Only): Power Failure Alert: Receive SMS/APP/Email alerts upon power failure or restoration.
• Function 5: E-Mail Pushing: Receive email notifications when temperature reaches preset values.
• Function 6: APP Pushing: Get app notifications to stay informed about device status.

4.4 Web Control

The device can be centrally controlled via a web browser on a PC, offering a comprehensive interface for managing equipment.

4.5 Short-time Trigger Switch (Inching)

This function allows for a brief activation of the relay (1 to 9 seconds settable), suitable for applications like opening garage doors. This allows you to trigger the action and then automatically switch off after a set duration.

5. Maintenance

• Keep the device clean and free from dust and moisture.
• Regularly check all wiring connections for tightness and integrity.
• Ensure the antenna is securely connected for optimal signal reception.
• Periodically verify the functionality of connected sensors and controlled equipment.
• For optimal performance, ensure the SIM card has an active data plan and sufficient balance.

6. Troubleshooting

• Device not responding to commands:
  • Check if the SIM card is properly inserted and has an active 4G LTE data plan and sufficient credit.
  • Verify the power supply to the controller.
  • Ensure the antenna is connected and in an area with good 4G signal.
  • Confirm that the phone number or app is correctly configured and authorized.
• Temperature alerts not received:
  • Check the temperature sensor connection.
  • Verify temperature threshold settings in the app or via SMS commands.
  • Ensure notification settings (SMS, App push, Email) are correctly configured.
• Relay not switching:
  • Check the wiring to the connected equipment and the relay output terminals.
  • Ensure the load does not exceed the relay's maximum ratings (30A/30VDC, 30A/250VAC, 30A/125VAC).
  • Test the control command again.
• Power failure alert not working (TVC version):
  • Ensure you have the TVC version of the controller.
  • Verify the power failure alert settings are enabled in the app or via SMS.
