begin moving to the defined value based on the azimuth potentiometer position sensor. Once
detected, the azimuth will follow the logic below to derive the center of the azimuth magnetic
switch. After the position sensors (i.e. Magnetic reed switch and/or potentiometer) have found the
physical center, the precision feedback sensors are initialized (i.e. encodes).
-
Move to the Counter-Clockwise side of the magnetic switch.
-
Move through the magnetic switch to the Clockwise side. Record the values of the
transitions on and off the switch.
-
Move through the magnetic switch to the Counter-Clockwise side. Record the values of
the transitions on and off the switch.
-
Calculate the center of the switch, removing hysteresis effect. Move to the calculated
center of the switch.

Setting the Elevation Axis
When performing the “Home” command for the first time, the system will first move to a defined
position using the elevation position sensors (i.e. switches and/or inclinometers). This action moves
