The safe choice – EKS with touch panel up to PL e

Without suitable operating modes, safety guards (e.g. safety doors) on many machines and installations still must be tampered with by bypassing for maintenance and servicing work. Providing operating mode selection allows the operator to select the required operating mode (e.g. setup mode) and activate the suitable safety guard (e.g. enabling switch). The Electronic-Key-System EKS is ideal for convenient operating mode selection in full compliance with laws.

This was previously not possible due to the lack of suitable systems. This has now changed. Using the EKS FSA, it was for the fi rst time possible to develop a procedure permitting operating mode selection on a touch panel without additional mechanical controls. With this method the touchscreen meets all requirements from the risk assessment for a Performance Level (PLr). The procedure was approved by the Institut für Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung in St. Augustin (IFA).
