AccuControl

Combines are the only units that ship from the factory with a Case IH approved USB stick. The USB stick is found in the plastic pouch with the combine operator's manuals.

Contact your dealer to purchase the recommended USB stick.

First, verify there is a layer assigned in Work Condition > Layer. If no layer can be assigned, create a Manual Application Channel. (Search FAQ page for procedure).

Next, in Toolbox > Implement, set the implement type to "Hitch" (if equipped). Cycle the hitch down and up and see if the work state arrow appears.

If the work state arrow appears then change back to EHR implement. Cycle the configured EHR paddle forward to detent, then back to detent. It is crucial to detent valve.

Also note the tractor is running task controller, AccuControl (with the implement switch turned on), or a CNH planter, these will always override the EHR's.

If the work state arrow still does not appear, the tractor may need a software update. Please contact your dealer.

Yes, for pricing and availability, please contact your dealer. When contacting your dealer have your All-Makes harness number available. This can be located roughtly six inches from the display connector.

Overlap Control refers to the ability of the AFS Pro 600 or AFS Pro 700 to automatically shut off seed drive motors or row clutches based on the position of a planter section relative to an already-applied area of the field. Overlap Control is based on the as-applied map created by the display. (This feature also applies to Patriot Sprayers and Titan Floaters equipped with the AFS Pro 600 or AFS Pro 700 application control system.)

To enable Overlap Control, set the Overlap Control window to "On" in the Toolbox > Overlap Setup screen. Then set the desired Percent Overlap. The default value is 99%. This means that 99% of a section (hydraulically controlled or clutch controlled) must be overlapping a previously applied area before the section will turn off. A high percentage results in more overlap and very little skip; a lower percentage results in more skip and less overlap. The allowable range is 1% - 99%.

Overlap Control also requires that the Section Control Method, Start Early Distance, Stop Late Distance, Bar Distance, and Product Delay be set correctly. (see below)


Boundary Control refers to the ability of the AFS Pro 600 or AFS Pro 700 to automatically shut off seed drive motors or row clutches based on the position of a planter section relative to an inner or outer boundary in a field. (This feature also applies to Patriot Sprayers and Titan Floaters equipped with the AFS Pro 600 or AFS Pro 700 application control system.) Boundary Control is based on boundaries, and is not related to the as-applied map. To use Boundary Control, you must have existing Inner and/or Outer Boundaries for the current Field. Boundaries can be recorded in the AFS Pro 600 or AFS Pro 700, or can be exported from a compatible desktop software application.

To enable Boundary Control, set the Boundary Control window to "Yes" in the Toolbox > Overlap Setup screen. Then set the desired Percent Out Of Bounds. The default value is 1%. This means that when 1% of a section is outside an Outer Boundary (or inside an Inner Boundary) the section will shut off. A low value will result in very little application outside the boundary. A higher value will result in more application outside the boundary, but will also make the system less susceptible to the effects of GPS drift. The allowable range is 1% to 99%.

Boundary Control operates independently of Overlap Control, and is not affected by Start Early Distance or Stop Late Distance.

Bar Distance (Toolbox > Config) is the distance from the corrected GPS reference point on the vehicle to the seed drop point on the planter. It should be measured horizontally, on the ground, at the tractor centerline, with the planter in planting position.

The corrected GPS reference point will vary depending on the vehicle model and the GPS receiver offsets entered in the Toolbox > GPS Setup screen. Refer to your AFS Pro 600 or AFS Pro 700 Operator's Manual for Precision Farming and Framework Software for more information.

Product Delay (Work Condition > Controller Setup) is the amount of time that elapses between the operator starting the product drives and the product actually hitting the ground. This measurement is extremely important because it provides ground speed compensation for the rate or section control system. As travel speeds increase, the accuracy and precision of the Product Delay becomes even more critical to proper performance.

Start Early Distance (previously called Lead Distance) is the distance used to start the planter when exiting an overlap area. This distance can be adjusted to ensure that the planter turns on at the appropriate time to prevent overlaps or skips when leaving a previously-planted area (such as a headland). If your planter is starting BEFORE leaving overlap, decrease the Start Early Distance by the distance between the start and the overlap. If your planter is starting AFTER leaving the overlap area, increase the Start Early Distance by the distance between the start and the overlap.

Stop Late Distance (previously called Lag Distance) is the distance used to stop the planter when entering an overlap area. This distance can be adjusted to ensure that the planter turns off at the appropriate time to prevent overlaps or skips when entering a previously-planted area (such as a headland). If your planter is stopping BEFORE entering the overlap area, increase the Stop Late Distance by the distance between the stop and the overlap. If your planter is stopping AFTER entering the overlap area, decrease the Stop Late Distance by the distance between the overlap and the stopping point.

The allowable range for Start Early and Stop Late Distance is 0ft to 25ft.

Start Early Distance and Stop Late Distance work in conjunction with Bar Distance (the distance from the GPS receiver reference point to the seed tube) and Product Delay (the elapsed time between the "plant" command from the display, and when seed actually hits the ground). Both Bar Distance and Product Delay must be set correctly to ensure that the Start Early and Stop Late Distance values work properly. Start Early and Stop Late distances should only be adjusted to fine-tune performance after configuring Bar Distance and Product Delay. If you feel that you need negative values for Start Early and/or Stop Late distances, you likely have errors in your Bar Distance and/or Product Delay.

Your local Case IH dealer or the AFS Support Center can assist you with configuring your planter.

Varieties should always be put in as Products.

These Products can then be assigned to map layers in Work Condition > Layer.  This will ensure that variety information is recorded properly for analysis in the desktop software, and for use with the automatic Variety Tracking feature in Case IH combines.

Yes, always assign a Default Rate for the Product when defining a Product in the Product Setup screen (Toolbox > Product).

You should also assign the Min Rate, Max Rate, and Delta Rate for the Product.  This will ensure that the Product setup is completed successfully.

When a prescription is exported from the desktop software, the software will ask the user for a default rate to be used when the vehicle leaves the prescription zone.  If a default rate is not specified, the prescription will use a default rate of "0" for product application outside the prescription zone.

The Default Rate assigned in the Product Setup screen (Toolbox > Product) is only used during manual product application.

The three basic parameters that we tune with are Gain, Deadzone and Breakout

Gain: How aggressively the system will attempt to change rate Deadzone: percentage away from target rate before flow is adjusted Breakout: The initial amount of PWM/Servo voltage required to move the valve

There are also two types of Gain to adjust depending on the valve used: PWM valves use the Integral Gain Servo valves use the Proportional Gain

For specific values please contact your dealer with the brand, type, and diameter of the valve being used.
