Product Introduction
The EXOR UNIOP ETT-VGA (6ZA1005-7) is a legacy industrial Human Machine Interface (HMI) designed for machine automation and process visualization. It provides operators with a graphical VGA touchscreen to monitor and control PLCs and other industrial equipment reliably.Built for demanding factory environments, this panel operates on a standard 24VDC supply with a low power draw of just 0.70A. Its compact, rugged design allows for easy integration into control cabinets and machinery panels, serving as a durable bridge between human operators and complex automation systems.
Installation & Configuration Guide
Phase 1: Preparation (10 min)
- Power Down: Ensure the main control cabinet and the 24VDC power supply are completely turned off.
- Verify Model: Double-check the label on the back of the unit reads 6ZA1005-7 to ensure it matches your project’s electrical requirements.
- Tools Needed: Phillips screwdriver, wire strippers, and a multimeter.
Phase 2: Panel Mounting (10-15 min)
- Cutout: Prepare the standard rectangular cutout in the control panel door according to the ETT-VGA mounting template.
- Insert: Slide the HMI unit into the cutout from the front.
- Secure: From the back, attach and tighten the mounting clips (usually included with the unit) to secure the panel firmly against the door. Do not overtighten, as this can warp the front bezel.
Phase 3: Wiring & Power (10 min)
- Locate Terminals: Find the power terminal block on the rear of the unit.
- Connect Power: Wire the 24VDC positive (+) and negative (-) leads. Ensure the power supply can comfortably handle the 0.70A load.
- Grounding: Connect the chassis ground (PE) to a proper earth ground to prevent electrical noise interference on the screen.
Phase 4: Power-On & Test (10 min)
- Voltage Check: Before flipping the main breaker, use a multimeter to confirm the incoming power is stable at 24VDC.
- Boot Up: Turn on the power. The UNIOP logo should appear on the VGA screen.
- Communication: Verify that the communication cable (serial or Ethernet, depending on your specific project setup) is securely connected to the PLC.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Quick Fix |
|---|---|---|
| Screen remains black | No power or loose wiring | Check the 24VDC supply with a multimeter. Ensure the polarity (+/-) is correct at the terminal block. |
| Touch response is inaccurate | Calibration drift | Access the HMI system settings menu and run the “Touchscreen Calibration” utility. |
| No communication with PLC | Wrong COM port or baud rate | Verify the communication parameters (baud rate, parity, station number) in the project software match the PLC exactly. |
| Screen flickering | Electrical noise / Bad ground | Check the grounding wire. Ensure the 24VDC power lines are routed away from high-voltage AC cables or motor drives. |
Dimensions, Mounting & Wiring Notes
- Mounting Method: Panel mount (requires a specific rectangular cutout in the enclosure door).
- Power Wiring: Strictly 24VDC. Reversing the polarity or supplying a higher voltage (like 110VAC) will instantly destroy the unit.
- Environment: Keep the rear of the unit clear of debris. Ensure the control cabinet has adequate ventilation, as excess heat can shorten the lifespan of the backlight.
- Handling: The front is a touchscreen. Avoid using sharp objects (screwdrivers, pens) to press the screen, as this can cause permanent physical damage.
FAQ
Q: The ETT-VGA 6ZA1005-7 is an older model. Is it still supported?
A: This is a legacy product from EXOR/UNIOP and is considered discontinued. While you can still find surplus stock, official manufacturer support and new replacements are no longer available. If your unit fails, you will likely need to look for a modern HMI replacement and reprogram the project.Q: What software do I need to program this HMI?
A: You will need the specific EXOR/UNIOP programming software compatible with the ETT-VGA series (often referred to as UniOP Designer or similar legacy suites). Note that modern HMI software usually cannot open or edit these older project files directly.Q: Can I replace my broken 6ZA1005-7 with a newer EXOR model?
A: Not directly. Newer EXOR or other brand HMIs will have different physical dimensions, cutout sizes, and communication protocols. A replacement would require mechanical modifications to the panel door and, more importantly, converting or rewriting the entire visualization project program.Q: My screen is dim or has dark spots. What is happening?
A: This is a common sign of backlight failure, which is expected after many years of continuous operation (typically 50,000+ hours). Since this is a discontinued model, replacing just the backlight is difficult. Usually, the entire unit needs to be swapped out.Q: Is the 6ZA1005-7 unit you sell new or used?
A: Due to its discontinued status, most available units on the market are “New Surplus” (unused old stock) or “Refurbished/Tested” (used but verified to be working). Please check the specific product listing or ask our sales team for the exact condition and testing report before purchasing.Q: Does this HMI support Ethernet communication?
A: The standard ETT-VGA series primarily relies on serial communication (RS-232/RS-485) for connecting to PLCs. While some specialized versions or add-on modules might exist, you should assume serial communication unless your specific project documentation states otherwise.
