LV800 Figure 7 Delay: A potentiometer is provided for setting the time delay between the time material is "sensed" (Yellow LED on) and the time the relay contact output changes (Red LED on). Units have a 1- turn potentiometer. A clockwise rotation will increase the delay from .25 to 15 seconds. This adjustment minimizes false sig- nals associated with temporary material shifts. The delay between the time material is "not sensed" (Yellows LED off) and the time the relay cont
