Pressure Transducer
This screen is displayed for vehicle profiles that use
a pressure transducer on Steering Valve. It allows
the user to adjust autosteer kickout sensitivity and
verify sensor is functioning properly.
Information and controls available on Manual
Steering Override screen for pressure transducers:
Pressure Graph
—Current pressure populates as
shaded green area starting from left side of graph,
kick out pressure is shown by triangles on bottom
and top.
Saved
—Value that is currently saved for manual
kickout.
Current
—Pressure reading determined by pressure transducer.
Minus (-) and Plus (+) Buttons
—Increases or decreases setting for kick out pressure. This moves two triangles left or right
on graph to manually adjust kick out pressure value.
Save Limit
—If kick out pressure values are changed from saved values, press this button to save them. If they are not
saved, any changes will be lost when user leaves this screen.
Autocal
—Auto Calibration wizard for pressure transducer. This is generally the best way to set up Manual Steering
Override value. It may be necessary to manually adjust this kick out value after Autocal wizard to take into account vehicle
specific behavior. Always test kick out in AutoSteer mode to determine if it working properly.
Change Samples
—Number of times system must detect kick out reading in a row before it considers that user has
started turning wheel. If this value is set too high, kick out will be slow to happen or not happen at all. If this value is set
too low, vehicle may spontaneously kick out from random pressure spikes. This value should be left at default value and
kick out limit adjusted first. Modify this value only if kick out limit is unable to provide a good balance.
Start
—Places system into an AutoSteer simulation. This will change to a Stop button after calibration start. Test kick out
setting by turning steering wheel. If system reaches kick out pressure the stop button will change back to a start button.
Use this procedure to test system and ensure kick out works properly.
Manual Steering Override Auto Calibrate
This wizard automatically calibrates manual
steering override value. Autocal automatically
tests system pressures and sets kick out value to
the optimal value for sucessful kick out.
