5 Rexroth supports machine and production system manufacturers with know-how and individual consulting. The guideline 10 Steps to Performance Level supports you by the evaluation of risks systematically and according to standards, by designing and implementing the corresponding safety measures. We gladly support you personally please contact us.

7 The ISO shows the way to fulfill the safety requirements of the European Machinery Directive for control systems. This standard considers the design and integration of safety-related parts of a control system (SRP/CS), regardless of the applied technology, such as electrical, hydraulic, mechanical or pneumatic. Furthermore, IEC regulates the specifications specifically for electronic control systems. The focus is on the parts of the control system which are relevant to the safety of the machine. As soon as the safety of a machine depends on a correct function of the control system, it is therefore called Functional Safety with special requirements on the availability of the Safety Function. Additional information can be found under:

8 The new design criteria and probabilistic calculations cover safety engineering classifications of components and systems for nearly all stationary and mobile machines. For this purpose, suppliers must provide information about the reliability of all involved electrical, hydraulic, mechanical and pneumatic components. Rexroth provides these data with all necessary additional information. Because of our product know-how and worldwide application experience, we know the interactions and interdependency between the different technologies applied for mechatronic systems. Take advantage from our knowledge.

10 Dividing the complex regulations into clearly defined working packages: This guideline shows the way from the risk assessment up to finally implementation and evaluation of the reached safety level. This systematics supports you in implementing the current state of the art of safety engineering for personnel protection in an economical and well documented way.

23 Discrete level used to specify the ability of safety-related parts of control systems to perform a safety function under foreseeable conditions Required Performance Level Safety Integrity Level (appropriated only for electronic control systems, see PL and IEC 62061) Statistic expected value of the mean time to failure Statistic expected value of the mean time to dangerous failure Unit used to measure the failure rate of electronic components (1 FIT=1x10-9 /h) Probability of dangerous failure per hour (reference value for PL and SIL) Statistic expected value of the number of cycles until 10% of the components have exceeded specified limits (response time, leakage, switching pressure, ) under defined conditions Expected number of cycles until 10% of the components fail dangerously Expected value of the mean time until 10% of the components fail dangerously (maximal service time of a component). Service life Diagnostic Coverage Common Cause Failure Safety-Related Parts of a Control System Failure which has the potential to put the SRP/CS in a hazardous or fail-to-function state
