How to locate the induction switch of the hot storage bin?

For example, locate the reject bin,First make sure the air pressure is enough,the position of the induction switch in the reject bin,Rotate the bin selection switch to the reject bin position ,confirm that the bin selection in place signal is activated,then turn the skip mode switch to the "manual" position,Press and hold the skip up switch, then the skip moves slowly until the induction switch of the reject bin is sensed and stops , At this time, release the skip up switch, press the skip stop knob, and turn the mode selection switch to the "memory" position, At this time, the system has memorized the position in the reject bin, Then loosen the skip stop knob, press and hold the skip down switch to move the skip to the position under the mixer.
