Like EN 954-1, it incorporates the safety-related parts of control systems (SRP/CS) in its area of application and all types of machines, regardless of the technology and energy form used (electric, hydraulic, pneumatic, mechanical, etc.). EN ISO 13849-1:2006 introduces the performance levels from PL a (lowest) to PL e (highest) and is determined by: • EN ISO 13849 categories (Cat B, Cat 1,….Cat 4) • Diagnostic Coverage (DC) • Mean Time To Dangerous Failure (MTTF d) The first two parameters relate to the control system, meanwhile MTTF d stands for the quality and 13849-1 MTTFd = 134.8 years instantaneous safety outputs EN/ISO 13849-1 MTTFd = 54.5 years time delay safety outputs EN/ ISO 13849-1 DC > 98.4 time delay safety outputs EN/ISO 13849-1 PFHd = 6.81E-9 1/h instantaneous safety outputs EN/IEC 62061 PFHd = 1.96E-8 1/h time delay safety outputs EN/ IEC 62061 Type of start Configurable Determining B10 values for pneumatic components according to ISO 19973 e converting a B10 value into an MTTFd value EN ISO 13849-1 Definition of the B10 value Statistically expected value for the number of cycles at which 10% of the components have exceeded the limit values defi ned for the test (switching time, leakage, switching pressure etc.) under specifi c conditions.

Annex C): ≡ Performance Level d (CEN ISO 13849-1. Table 2) ≡ Safety Integrity Level 2 (CEN ISO 13849-1. Table 3) ≡ MTTFd denotation HIGH (CEN ISO 13849-1.

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. Notice: According to EN ISO 13849-1:2015, higher MTTF D values can be assumed with a limited number of operations per year: n op MTTF D > 1,000,000 150 years For hydraulic components, the standard ISO 13849-1:2015 stipulates an MTTF D value of 150 years, assuming that basic and well-tried safety principles are applied. This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software.

The MTTFd value does not change when in a cascade configuration. Safety Light Curtain F3SG-4RA* SIL3 1.1E-8 e 4 100 98 – It conforms to IEC 61496-1 TYPE 4. As subsystem, it conforms to IEC61508 SIL 3 and ISO13849-1 PL e. For a cascade configuration, multiply the PFHd value by the number of sensor segments cascaded. The MTTFd value

The new standard contains a number of changes, one of which is that a new value for MTTFd is allowed ISO 13849-1 is a revised version of EN 954-1.

2019-06-12 · A machinery control system manages, commands, directs, or regulates other devices or systems. These systems can be simple, such as a thermostat that regulates a boiler. Or, complex, such as a control system for industrial processes. Regardless of how elaborate a machinery control system may be, it must follow several safety standards to ensure that it is safe and reliable. For that reason, it

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.
