Before deciding the design of your safety control system, it is necessary to understand which performance level you need to achieve in accordance with ISO-13849. A risk assessment is therefore required. At Phoenix Contact we have an App which can be used on an iPhone or iPad, giving the user an interactive risk assessment guide, 
therefore determining the performance level of the machine or application.
You can download the free App in iTunes here.
How do I know I have achieved the required performance level ?
One easy way to validate that you have achieved the correct performance level for your machine/application is to use a free software tool called SISTEMA. This is free to download from our website here.
