Hi Steve - the manufacturer of the light curtain will make that claim on their technical documentation for the specific device, but they will say it is capable of being connected as a type 2 or type 4. It basically boils down to the way it has been installed with the rest of the safety circuit components to ensure the whole safety loop meets the requirements for a type 2 or a type 4 system. Hope this helps! Email us on marketing@pilz.co.uk if you need any further info or have further questions.
How do you determine if the ESPE is type 4 or type 2?
