4. Setup & Installation

Careful installation and connection are crucial for the proper functioning of your HMI. Refer to the rear panel diagram for port identification.

4.1 Mounting

The HMI is designed for panel mounting. Use the provided mounting brackets and screws to secure the unit into a cutout of the appropriate size (192x138mm).

4.2 Power Connection

• Connect a DC24V power supply to the designated power input terminals on the rear panel. Ensure the polarity is correct.
• The HMI supports 12-24VDC ± 10% input.

4.3 Communication Connections

• Ethernet: Connect an Ethernet cable to the LAN port for network communication and program downloads using Modbus TCP protocol.
• Serial Ports: Utilize the RS232 and RS485 ports for communication with PLCs and other devices. The HMI supports MODBUS-Protocol, free port, and traditional PLC communication protocols.
• USB Host: An external U-disk can be connected to the USB 2.0 X1 port for program updates and historical data transfer.
• Programming Port: Use the Type-C port for connecting to a computer for programming the HMI.

5. Operation

The Coolmay TK8070H HMI provides an intuitive touch screen interface for monitoring and controlling industrial processes. Operation typically involves interacting with the custom-designed screens and controls programmed into the device.

5.1 Powering On

Once properly connected to a DC24V power source, the HMI will power on. Observe the 'RUN', 'COM', and 'PWR' indicators on the top right of the screen. 'PWR' should be lit, and 'RUN' and 'COM' will indicate operational status and communication activity, respectively.

5.2 Interface Interaction

Navigate through the HMI screens by touching the displayed buttons, input fields, and graphical elements. The specific functions and layout are determined by the application program loaded onto the HMI.

5.3 Programming and Configuration (Vcool Software)

The HMI is programmed using the Vcool configuration software. This software allows users to design custom interfaces, define data points, set up alarms, configure PID controls, and implement C language scripts for advanced functionalities. Programs are typically uploaded to the HMI via the Type-C programming port or Ethernet.

6. Maintenance

To ensure the longevity and optimal performance of your Coolmay TK8070H HMI, follow these maintenance guidelines:

• Cleaning: Regularly clean the touch screen surface with a soft, lint-free cloth. For stubborn dirt, use a mild, non-abrasive cleaning solution specifically designed for electronic displays. Avoid harsh chemicals or abrasive materials.
• Environmental Conditions: Ensure the HMI operates within its specified temperature and humidity ranges. While dustproof and waterproof, avoid exposing it to excessive moisture or extreme temperatures.
• Firmware Updates: Periodically check the manufacturer's website for firmware updates. Updates can improve performance, add features, or resolve issues. Follow the provided instructions carefully when performing updates, typically via the USB Host port.
• Connection Checks: Periodically inspect all cable connections (power, Ethernet, serial, USB) to ensure they are secure and free from damage.

7. Troubleshooting

If you encounter issues with your Coolmay TK8070H HMI, consider the following troubleshooting steps:

• No Power:
  • Check the power supply connection and ensure it is providing the correct DC24V voltage.
  • Verify that the power indicator (PWR) on the HMI is lit.
• Screen Not Responding:
  • Perform a soft reset by cycling the power to the HMI.
  • Ensure the touch screen is clean and free from obstructions.
• Communication Issues:
  • Check all communication cable connections (Ethernet, RS232, RS485).
  • Verify the communication settings in the HMI program match those of the connected device (e.g., baud rate, parity, data bits).
  • Observe the 'COM' indicator for activity.
• Program Loading Failure:
  • Ensure the Vcool software is correctly installed and configured.
  • Check the connection between your PC and the HMI (Type-C or Ethernet).
  • Verify the program file is not corrupted.

If these steps do not resolve the issue, please contact Coolmay technical support for further assistance.
