From the safety function to the product
From the safety function to the product: Our products with safety engineering.
An essential aspect of a safe machine is its “Functional Safety”. This means having a safety function, e.g. the machine switching off when a safety door is opened, that is always implemented or ensuring that an error is uncovered in the implementation of a safety function before it causes any injury to people.
The complexity and failure risk increases with each additional component in a machine. Deep integration of “Functional Safety” into the products and engineering tools will provide the necessary safety. The safety functions thus correspond to one element of the uniform standards.However, they are more convincing if they have application-specific functions that considerably reduce the engineering expenditure and provide additional benefits, such as reducing the need for large buffer zones in storage and retrieval units.
