Adjust System Settings

Machine SCV Flow

To determine correct flow setting, adjust flow up, with Active Implement Guidance engaged, until system starts to become erratic. Then adjust flow down until system stabilizes.

Left, Center, and Right Calibration

Ensure system has a good max left, center, and max right position calibrations. Center calibration is critical since Active Implement Guidance system uses center calibration for line acquisition. When calibrating max left and max right positions, continue holding pressure on SCV lever once it has reached its max position. Left and right directions are based on operator sitting in cab facing forward. Ensure steering system is turning in direction it is being calibrated for. Some applications with steer systems are difficult to see from cab and require physical confirmation of steer direction. Do not assume system is going the correct direction if it cannot be seen. Hydraulic hoses hooked up backwards cause system to steer in opposite direction.

Extend and Retract Threshold Setting

NOTE: Machine must be moving forward at a minimum of 0.8 km/h (0.5 mph) to perform extend and retract threshold tests.

Look for point at which system starts to move. If value is too low, system does not react. If value is too high, system performs erratically or consistently over shoot guidance line. Verify proper performance of feedback sensor by watching voltage on same page as extend and retract tests. Voltage must raise and lower at a steady pace with no erratic jumps. If there is no voltage reading, check implement feedback sensor harness, and verify feedback sensor has not failed. Once threshold settings are established, no more adjustments are needed unless SCV flow or counterbalance valve is adjusted.

Line Sensitivity Tracking

Line sensitivity tracking is dependent on each system and how it reacts when acquiring line after a turn. Line sensitivity tracking values vary from 2000—9000. Systems with large steer cylinders require a higher value. If system is over shooting line or s-ing back and forth across it, line sensitivity tracking is too high. If system is slow to acquire line, line sensitivity tracking is too low. Since there is a large range of values for line sensitivity tracking, make large adjustments until desirable reaction is seen. Then adjust sensitivity with smaller values.

Line Sensitivity Accumulated

Line sensitivity accumulated value most likely will be close to a quarter of what line sensitivity tracking is. For example, line sensitivity tracking—2400 and line sensitivity accumulated—600. This setting affects performance of system after line is acquired and tracking. If system does not correct offline error, adjust setting until system starts holding line.

Line sensitivity tracking and line sensitivity accumulated vary depending on system. It is necessary to watch behavior of system when acquiring line, and after tracking on line. Higher sensitivity values result in quicker response, and lower numbers result in slower response.

Wheel Sensitivity

Wheel sensitivity is dependent on each system. This setting is similar to wheel angle sensitivity on integrated machines. Find a value that shows consistent and favorable reaction on system. Wheel sensitivity directly affects line sensitivity tracking and line sensitivity accumulated.

Start with one sensitivity, and get that specific sensitivity correct. Then work on the next sensitivity.

GPS Receivers

Calibrate TCM, on implement receiver and machine receiver. Implement receiver height must be entered on StarFire™ page, not in implement setup on GreenStar™ page. Implement receiver height is working height of receiver with implement in ground. Mount receiver as close to center of implement, and as close to steering system as possible. Only enter offsets for left and right. Set fore and aft dimensions to 0. 

If receiver is positioned off center to the right, select Shifted Right and enter number of inches it is off center. If receiver is positioned off center to the left, select Shifted Left and enter number of inches it is off center.

For optimal system performance, mount implement receiver directly above the control point in relation to fore/aft position. If system is not reacting favorably on hilly terrain, adjust receiver mounting location closer to control point.

System Steers in One Direction

Check system for in-line check valves and remove them.

If no change, use following steps:

Swap hydraulic hoses around. After changing hydraulic hoses, calibrate max left, center, and max right positions. If system steers in opposite direction, determine which direction is extend, and which direction is retract. Calibrate max left, center, and max right positions. Center calibration is critical to line acquisition. If implement does not track straight, calibrate center position.

If system continues to steer in one direction after swapping hydraulic lines:

1. Turn off machine.

2. Unhook 10-pin and 4-pin connectors on controller.

3. Start machine and let up system boot.

4. Turn off machine.

5. Connect 10-pin and 4-pin connectors.

Side Shift 3-Point Hitch Locks in One Direction

An implement feedback sensor is not required with side shift hitch applications. If hitch is shifting fully to left, or right, and getting hung up in that position, install an implement feedback sensor and sensor harness. After installing sensor, change control selection from Implement Shifting, to Implement Steering. After changing control selection, calibrate left, center, and right positions.
