Depending on the application, machine installations can be subdivided into safe and unsafe zones. Experience in mechanical engineering has shown that approximately 90 % of technical safety applications comply with the requirements of EN 954-1, Category 3, and just10 % comply with the highest level, Category 4 (Source: VDW).
Active safety technology products are designed for applications in accordance with the provisions of EN 954-1 Category 4, which is a technically and financially challenging approach that often exceeds practical requirements.
- Represents a milestone on the road to safety technology.
- Complies with all EN 954-1, Category 3 requirements.
- Has impressive technical and financial advantages.
The requirements are determined on the basis of the relevant standards. The new prEN ISO 13849-1 standard represents a balancing act between the deterministic EN 954-1 standard and the probabilistic DIN EN IEC 61508 standard (Source: BGIA).
Passive safety distributors replace manually wired EMERGENCY STOP terminal boxes in the field. 2-channel EMERGENCY STOP buttons can be quickly and easily connected using preterminated M12 cables by means of the safety distributor. The distributor automatically combines individual buttons to create an EMERGENCY STOP loop.
Additional M12 plug-in locations for acknowledge buttons and machine lamps also make installation easier. The safety distributor indicates the point at which the EMERGENCY STOP loop has been interrupted when an EMERGENCY STOP button is pressed. This has tremendous advantages during service and maintenance.
