Angle Hall Sensor - Main Pillar: Notes

The angle sensor for the main pillar is mounted on the left side top linkage by the left main pillar hydraulic cylinder. The angle sensor receives power (5 volts) and ground from the CVM. It provides a linear voltage signal input from approximately 0.5 to 3.5 volts as the top frame is lowered into and raised out of the storage compartment.

The CVM uses the input signal from the main pillar angle sensor for top frame positioning
