The KEBA HMI terminals Touch Screen Issues:

Improper calibration
Check for activation points that are offset from touch points. Calibrate the touch screen.

Non-functioning touch screen
Check the touch screen for damage, such as cuts or excessive wear. If there is damage, replace the terminal.

Touching multiple-input elements
Application screens contain graphic input elements that are configured in the Machine Edition application. When touched, these elements perform operations in a predictable manner. For example, an input element is configured to navigate to a specific screen in the application or start a motor when touched.

Multiple operations cannot be conducted simultaneously. Doing so results in an unintended operation.
• Do not touch multiple input elements simultaneously.
• Do not rest a hand or multiple fingers on the display.
