- USB Connection: For program download and monitoring, connect a standard USB cable from the USB port on the rear of the panel to your PC.
5. Operating Instructions
5.1 Powering On and Indicators
Once connected to a power source (PC via USB or PLC via RS-232), the green Power LED indicator will light up, indicating the unit is powered on. The red Alarm LED indicator will flash according to specific statuses:
- Flashes three times when connected with DVPACAB2A30P.
- Flashes with a buzzer sound when user-defined settings are matched.
- Indicates communication errors or other special conditions programmed by the user.
5.2 Using the Display and Keys
- Display Area: The LCM display will show the current program status, data, and messages as configured in the HMI program.
- Numeric Keys (0-9): Use these keys to input numerical data. Their functions can also be customized within the HMI program.
- F Key: This is a user-definable function key. Its action depends on the HMI program loaded.
- ESC Key: Press to cancel an operation, exit a menu, or return to the previous screen.
- Enter Key (ENT): Press to confirm an input, accept a value, or execute a command.
- Arrow Keys (Up/Down/Left/Right):
- Up/Down: Navigate through menus, increase/decrease numerical values, or scroll through pages.
- Left/Right: Move the cursor, select specific positions within a field, or navigate horizontally.
5.3 Backlight and Contrast Adjustment

- Contrast: The display contrast can be adjusted in 10 levels via the programming software to optimize readability.
5.4 Program Download and Monitoring
Programs for the TP04G-BL-CU are downloaded from a PC using a virtual COM port via the USB interface. This method also allows for monitoring the panel's operation.
6. Maintenance
6.1 Cleaning
To clean the front panel, use a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the display or casing. Ensure no liquid enters the device.
6.2 Environmental Conditions
To ensure optimal performance and longevity, operate the TP04G-BL-CU within the specified environmental conditions:
- Operating Temperature: 0°C to 50°C
- Operating Humidity: 20% to 90% RH (non-condensing)
- Storage Temperature: -20°C to 60°C
The front panel has an IP66/NEMA4 waterproof rating, protecting it from dust and strong jets of water. However, the rear of the unit is not similarly protected and should be shielded from moisture and excessive dust.
7. Troubleshooting
7.1 Power and Display Issues
- No Power LED: Check the power connection. Ensure the USB cable is properly connected to a powered PC, or the RS-232 cable is correctly connected to a PLC providing 5V DC.
- Blank Display: If the Power LED is on but the display is blank, check the backlight settings in the HMI program. Adjust contrast via software if the display is faint.
- Alarm LED Flashing: Refer to your HMI program documentation for specific alarm codes or conditions that trigger the red LED. Common causes include communication errors or user-defined events.
7.2 Communication Problems
- No Communication with PLC: Verify the RS-232 cable connection. Check the baud rate, data length, stop bits, and parity settings in both the HMI and PLC programs to ensure they match.
- Program Download Failure: Ensure the USB cable is securely connected and the correct virtual COM port is selected in the programming software. Check for driver installation issues on the PC.
7.3 Resetting the Device
If the unit becomes unresponsive, locate the Reset key on the back panel and press it to restart the device. This may resolve temporary software glitches.
