4. Nastavitev
Follow these steps to properly install and set up your HMI Touch Screen:
4.1 Montaža na ploščo
- Prepare a panel cutout according to the specified dimensions (approx. 130mm x 80mm).
- Insert the HMI unit into the cutout from the front.
- Secure the HMI unit using the provided mounting brackets and screws from the rear of the panel. Ensure a snug fit to maintain IP65 front panel protection.
4.2 Žične povezave
Refer to the rear panel diagram (Figure 3) for port locations.
- Napajalni priključek: Connect the 24V DC power supply to the power cable terminal. Ensure correct polarity (+/-) and that the voltage is within the working range of ±15%.
- Serijska komunikacija: Connect your PLC or intelligent controller to the COM1 port using an appropriate RS232, RS485, or RS422 cable.
- USB povezave: The USB 2.0 Device port is used for program download from a computer. The USB 2.0 Host port supports U disk for data transfer and program updates.
4.3 Začetni vklop
Once all connections are secure, apply power to the unit. Observe the indicator lights:
- PWR: Označuje stanje napajanja.
- TEK: Označuje stanje delovanja.
- COM: Indicates serial communication activity.

5.2 Program Download and Configuration
The HMI supports data download and automatic display configuration. This eliminates the need for complex programming directly on the device. Typically, configuration software on a PC is used to create the HMI interface, which is then downloaded to the device via the USB 2.0 Device port or a U disk connected to the USB 2.0 Host port.
6. Vzdrževanje
Proper maintenance ensures the longevity and optimal performance of your HMI Touch Screen.
- Čiščenje: Uporabite mehko, damp krpo za čiščenje zaslona in casing. Avoid abrasive cleaners, solvents, or harsh chemicals that could damage the display or housing.
- Okolje: Operate and store the device within the specified temperature and humidity ranges to prevent damage. Avoid direct sunlight and excessive dust.
- Povezave: Periodically check all cable connections for tightness and signs of wear.
7. Odpravljanje težav
If you encounter issues with your HMI Touch Screen, refer to the following common problems and solutions:
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Zaslon je prazen | No power, faulty power cable, or unit not turned on. | Check power connections, ensure 24V DC supply, and verify the PWR indicator light is on. |
| Touch input unresponsive | Screen calibration issue, physical damage, or software error. | Restart the device. If the issue persists, check for physical damage. Re-download the HMI program if necessary. |
| Communication error with PLC | Incorrect wiring, wrong communication protocol settings, or faulty cable. | Verify serial cable connections. Ensure the HMI and PLC communication settings (baud rate, parity, data bits) match. Check the COM indicator light for activity. |
| Display flickering or distorted | Power supply instability, environmental interference, or internal fault. | Ensure stable power supply. Check for strong electromagnetic interference sources. If the problem continues, contact support. |
