122. uth drives the CW antenna until the Home Switch is contacted which presets the relative position counter to the value stored in the Home Flag Offset This assures that the encoder input increments decrements from this initialization value so that the encoder does not have to be precision aligned The Home Switch is a micro switch with a roller arm which is actuated by cam mounted on the azimuth driven sprocket or it is a hall sensor which is actuated by a magnet mounted on the azimuth driven sprocket which produces the Home Flag signal The Home Flag Offset is a value saved in NVRam Non Volatile RAM in the PCU This value is the relative position of the antenna when the home switch is engaged Presetting the counter to this value assures that when the antenna is pointed in line with the bow of the ship the counter will read 000 0 Relative 360 0 000 0 In most cases when the antenna stops at the home flag it will be pointed in line with the Bow of the ship 360 0 In these cases Home Flag Offset HFO should be set 0000 to zero When Optimizing Targeting small variations 2 up to 5 0 degrees Azimuth corrected using If it AZ TRIM as described the Optimizing Kf Targeting procedure above Large variations in Azimuth position indicate that the Relative position is incorrect and should be calibrated using the correct HFO value instead of an Azimuth Trim offset This is especially true if
