Ken, Don't rely on your pacer to give you an accurate measure of rotor loss.The sensor is mounted in a position that will give you a false reading all the time.Set your pacer to shoe,take counts behind the machine for loss,subtract headloss,then adjust your machine to try and achieve 1% or less of yield.(100bu_A.= 1bu. total loss across the machine.) Once you are satisfied with your settings,then set pacer settings so that it stays in the green or yellow.(Around here I tell my customers Range 1,Setpoint 5-8)As for the rotor loss,what are your settingsIJCylinder speedIJConcave clearanceIJWhat is your loss count across the width of the machineIJMaybe we can give you some more insight after these questions are answered.
