Frequently Asked Questions

What is "Muting" used for?
It allows temporary, safe suspension of the safety field to permit material transfer without stopping the machine.

How many beams do I need for my application?
Three beams are suitable for detecting the presence of a person. The 400mm spacing helps prevent crawling under.

Can it monitor my safety contactors?
Yes, the EDM (External Device Monitoring) input can check if your safety relay or contactor has dropped out correctly.

What is the difference between operating modes?
Modes (set via pin 2) change the behavior of the muting and restart functions. Refer to the manual for your specific needs.

Is this suitable for outdoor use?
With an IP67 rating, it is protected against dust and temporary water immersion, but direct rain or extreme conditions may require a hood.
