Non-compliance with transport, storage, installation, or maintenance requirements voids the warranty.
| Condition | Troubleshooting |
|---|---|
| No earth connection or protective conductor connection | Malfunctions of the capacitive touch screen; may cause personal injury or property damage. Always connect the device to a grounding conductor or protective conductor. Ensure low impedance connection to earth. Connect protective conductor to the control cabinet/system with a minimum cross-section of 2.5 mm². |
| Maloperation | Configure the plant so safety functions are not operated by touch screen. Switch off for cleaning/maintenance. Keep touch screen clean. |
| Improper execution of gestures | Gestures may not be recognized or may be recognized incorrectly, leading to unintended device implementation. Incorrect execution can cause plant errors and physical injury. Touch screen reacts to surface contact, not pressure. Use capacitive touch pens. Avoid unintended multiple touches. Familiarize yourself with gestures and applications. |
| Touch screen locked (security reasons) | Conductive liquid on screen with ground contact, or electromagnetic interference exceeding EN 61000-4-2. Touch screen unlocks when interference ceases. |
