The swing sensor is located in the collector ring assembly under the hydraulic swivel. The job of the
potentiometer is to track the movement of the upper half of the crane all the way around the swing
circle. This function can only be zeroed in the stowed, or house lock positions, and the numbers should
count up, when rotating to the right or in a clockwise direction. If no swing potentiometer is present,
calibration is not required.
