What should you do if your machine is getting on in years? We show Pilz’s systematic approach to bringing plant and machinery back up to the state of the art – including higher availability and a longer service life.
You can find them almost everywhere: “classic machines” in production halls. They have been working hard for many years now. Up-to-date automation and safety technology can breathe new life into them. However, a so-called retrofit of the machines generally leads to a number of questions. But the focus is always: the question of cost effectiveness. In the first step it is therefore important to consider what the retrofit should include: a simple exchange of old for new, or should the existing machine be expanded or the process optimised and adapted? How does Pilz support customers when answering these questions? Back to the beginning!
1. The risk assessment
Experts from Pilz thoroughly examine the “classic machine” under consideration in the first step and create a risk assessment: Where does the plant or machinery stray from the state of the art according to the current standards situation? Which safety-related gaps have to be filled? And how? For this purpose, Pilz also makes basic suggestions for achieving the necessary mechanical and safety-related protection objectives as part of a safety concept.
2. The safety design
If needed, our experts then create a detailed safety design for the implementation – a consulting component that smoothly transitions into the implementation and includes hardware as well as software, where possible. Which components should be exchanged in order to preserve availability? Which movable guards or protective devices should be used to guarantee safety of the machine and increase availability and productivity? Which electronic access systems could improve the protection against manipulation? Consulting is adapted to the individual needs of the customer here – from smaller to larger retrofit scopes – and is initially fully product-neutral. The customer can then decide how to proceed with the retrofit, and with whom. If so desired, Pilz will provide the entire package from one source: Consultancy service including engineering and integration.
3. Following the conversion: the verification and validation
Before completing a successful conversion, the verification and validation of the targeted safety features must still be performed. After all it’s not just important what one does, but also that each step is checked for accuracy. An approach that is a matter of course at Pilz. Protocols required by standards transparently verify every step.
4. Training the employees
And finally, the employees should also be able to easily and straightforwardly deal with the machine upgrade in their daily work. The experts offer seminars for safety-related software, hardware and design as well as machinery safety and CE seminars in the training centres at Pilz locations or on-site with the customer. On the whole, an all-round safe and sustainable retrofit!
