4 Determining the PL If the categories, and are known, the performance level (PL) can be determined based on the table. Example 1: SG-EFS 104/2W Category 3 = 60 % = 257 years Result: => => => PL d Simplified process for determining the achieved PL Category B none none medium medium medium a a b b c b b c c d c c d d d e table table Designation Zone none < 60 % 60 % < 90 % medium 90 % < 99 % 99 % Designation Zone 3 years < < 10 years medium 10 years < 30 years 30 years < 100 years PL => SIL Performance Level (ISO13849) Safety Integrity Level (IEC 61508) Probability of a dangerous failure (PFH) [1/h] PL a 10-4 > X 10-5 PL b SIL > X 3x 10-6 PL c SIL 1 3x 10-6 > X 10-6 PL d SIL > X 10-7 PL e SIL > X 10-8 Note: Safety edges, safety mats or safety bumpers can reach PL d as a maximum. 4/5 Consensus with ISO

5 Determining the sensor = 0.1 Example 2: Safety mat in front of processing centre with 30-second cycle in 3-shift operation, 250 days per year. = 120 actuations/h x 24 h/day x 250 days = 720,000 actuations per year = / (0.1 x ) = 6,000,000 / (0.1 x 720,000) = 83.3 years => Example 3: NC safety edge on sliding gate with 2 actuations per day (morning and evening), 365 days per year. = 2 actuations/day x 365 days = 730 actuations per year = / (0.1 x ) = 2,000,000 / (0.1 x 730) = 27,397.3 years => Determining the overall = + SG sensor Example 4: As in example 2; Safety mat SM connected to SG-EFS 1X4 ZK2/1. SG = 313 years SM = 83 years = years 83 years = 65 years => Note: This is a very simplified description, which only approximates the determination of the real overall MT- TF D. Other factors that must be taken into account: + supply lines between the sensor and the control unit + different channels + supply lines between the control unit and the machine + types of connections Glossary PL SIL number of cycles until 10 % of the components have undergone dangerous failure (for electromechanical components) average diagnosis consistency level; measure for the effectiveness of the diagnosis, which can be defined as the ratio of the failure rate of the detected dangerous failures to the failure rate of the overall dangerous failures mean time to dangerous failure average number of actuations per year; = (3600 s/t cycle )/h h op d op Performance Level; discrete level that specifies the ability of safety-related elements of a control system to execute a safety function under predictable conditions Safety Integrity Level; discrete level for specification of the safety integrity of the safety function Consensus with ISO /5
