What Is the PanelView 550?

The PanelView 550 is a high-performance operator terminal featuring:

• A space-saving construction.
• A flat panel design. 
• A fiber optic backlight.
• A 5.5-inch diagonal LCD monochrome screen. 
• A lamp to illuminate the fiber optic strands.
• A keypad and touchscreen input combo with 10 functional keys and numeric keypads.

The PanelView 550 performs best at 32 to 131 degrees Fahrenheit (0 to 55 degrees Celsius). The back panel is accessible for wiring, maintenance and troubleshooting.

How the HMI Device Works

A Human Machine Interface (HMI) shows operational information about a system, such as its status and parameters. The HMI sends commands to a Programmable Logic Controller (PLC) over a communication network. The PLC then collects sensor data and uses this information to control outputs such as valves and motors. The HMI displays this information to the operator and processes the user’s input.

Common PanelView 550 Touchscreen Failures 

Some common failures our technicians troubleshoot include:

Pronounced Lines Through the Screen and Fading Contrast

This could be due to various reasons:

• The processor board is not working.
• The cable connecting the LCD to the processor board is loose.
• There is corrosion inside the connector.
• The LCD is not working and needs replacing.

How to Fix

Our technicians can fix this issue by:

1. Replacing the old PanelView 550 LCD with a new LCD.
2. Holding the bottom right screen to go to configuration mode. The lines will be gone and the image will be clear and bright.
3. Checking the brightness, contrast, backlight timeout and different video modes. 
4. Testing the touch functionality to see if all portions of the touchscreen are functional.

Our specialist will then replace the overlay, clean the unit and ship it back to you.

Blank Screen

A blank screen might be due to:

• Low voltage reaching the component.
• A broken LCD.
• The backlight failing to illuminate.
• An outdated bulb.

How to Fix

We address this problem by:

• Turning up the voltage. If the cursor is slightly visible, the LCD is functioning, and the problem could be the backlight.
• Turning off the power and opening the back plate to access the lamp.
• Powering the device back on and using pins to measure the lamp’s DC voltage. It should be around 5 volts. After confirming the voltage, we can conclude that the problem is the backlight.
• Turning off power, removing the old lamp and installing a modern LED bulb, ensuring it aligns with the glass and fiber optics. Old bulbs are prone to failure and have short life expectancies.
• Putting the cover back on and testing the device. 

Our technicians will perform additional tests on the machine, clean it and ship it to you.
