Structural Characteristics
- Panel flush mounting structure for cabinet door cutout installation.
- Front surface integrates LCD display, touch area and arranged physical function keys.
- Rear casing contains PCB assembly, power terminal and serial communication connectors.
- Sealing gasket between front frame and cabinet door provides dust and splash protection.
- Rear mounting clips fix the panel to cabinet door.
- Internal layout isolates low voltage logic circuit from external wiring terminals.
Working Principle 24VDC power supplies the terminal hardware. The panel communicates with PLC via serial bus to continuously read register data. The main controller renders graphics, numerical values and alarm information on VGA LCD. Touch controller and physical key circuit capture operator operation events and transmit corresponding commands to PLC. Real-time clock provides timestamp for alarm and log entries. Flash memory retains project, recipe and event data after power loss.
Installation Requirements
- Prepare cabinet door cutout matching panel dimension drawing.
- Install sealing gasket before inserting panel into cabinet opening.
- Fasten rear mounting clips evenly.
- Use shielded twisted pair cable for serial communication wiring.
- Separate signal wiring from high-current power cables.
- Connect protective earth terminal to cabinet earth bar.
- Download HMI project and set communication parameters after wiring completion.
Usage Notes
- Avoid sharp objects contacting touch screen surface.
- Do not apply high pressure spray water directly onto front panel.
- Keep cabinet rear area dry and free of corrosive vapors.
- Backup project file before any firmware or project modification.
- Check communication cable connection periodically under vibration conditions.
- Replace backlight component once display brightness degrades.
- Perform periodic project backup for spare unit replacement.
