operations where 10% of the components fail to danger. The corresponding MTTFd value is calculated from the B 10d value and the switching cycles of the component (see EN ISO 13849-1). Measures to take to combat common cause failures (CCF) are described in EN ISO 13849-1, such as: Physical separation between the signal paths Diversity 13849-1 MTTFd: High Average Diagnostic Coverage EN ISO 13849-1 DCavg: Medium Stop Category IEC 60204-1 Stop category 0 Safety Function IEC 61800-5-2 STO Hardware Fault Tolerance IEC 61508 HFT = 1 Subsystem IEC 61508 B Items Standards Performance Level … The HR2S series safety relays provide users increased functionality and flexibility when designing system to meet safety requirements. HR2S safety relays are compact modules designed to allow machine operation only when all safety controls such as Interlock Switches, E-stop switches, Light Curtains, etc.

However, the machine norms, e.g. EN 15011 for bridge and portal cranes still kept EN 954-1 as the relevant norm for the safety of the electrical equipment of the crane. This EN ISO 13849-1:2015: MTTF D = B 10D 0.1 x n op B 10D = Mean number of cycles in which up to 10% of the components have failed in a dangerous manner. n op = Mean number of annual actuations.

Annex C): ≡ Performance Level e (CEN ISO 13849-1. Table 2) ≡ Safety Integrity Level 3 (CEN ISO 13849-1. Table 3) ≡ MTTFd denotation HIGH (CEN ISO 13849-1. Table 4) t EN 13849-1 was put into place in 2006 in order to replace EN 954-1. The main reason for that was to also consider the importance of failures-in-time of the design and its components, not only its architecture as for 954-1. However, the machine norms, e.g.
