Q & A: Category 2 and Testing Intervals

This entry is part 1 of 2 in the series Q&A

Dur­ing the Free Safe­ty Talks that we did with Schm­er­sal Cana­da and Franklin Empire, we had a “hot ques­tion” come up regard­ing Cat­e­go­ry 2 archi­tec­ture and the test­ing inter­val require­ment. In the short video below, Doug answers that ques­tion.

If you have more ques­tions or felt some­thing wasn’t clear in the video, leave us a com­ment and we will get back to you!

If you are hav­ing prob­lems with devel­op­ing your safe­ty func­tion, please get in touch with Doug direct­ly.
