Section Control Settings

Raven field computers can adjust section control settings, allowing the operator to customize when sections are turned on or off during field operations.

Adjust Section Control Settings

To adjust any of the Section Control settings:

Select Settings on the bottom left of the Home screen. The Settings Menu will open.
Select Section Control on the Settings menu. The Section Control window will open.
Select in the cell to the right of the desired setting.
Enter the desired setting.
Note: If using a RavenAccuBoom™ node, select the Use AccuBoom™ checkbox and the AccuBoom™ node will control the sections for the implement selected in the drop-down list.
Select Accept to return to the Section Control window.
Select Accept to save the displayed settings and return to the Settings menu.

The number of sections is based on the information entered while creating the implement. The default settings for On Override is five seconds. The default Turn Off Percent is 95%. The default Exiting/Entering Overlap is zero meters. The default Boundary Percent Overlap is 5%. To adjust the number of sections, adjust the tractor settings.

On/Off Override

The On/Off Override feature allows the operator to override the automatic section control and force all AccuBoom™ controlled sections on for a user defined interval. This feature is useful for re-applying product to a heavily infested field area or when accelerating from a complete stop. The time for the override may be modified to match specific application needs.

Turn Off/On Percent

Turn Off/On Percent allows the user to define the amount of coverage tolerated during an application. For applications which require complete coverage, the coverage percent setting should be set to a higher value (80% to 100%). When applying products that do not tolerate overlaps, the percent coverage should be set to a lower value.

Exiting/Entering Overlap

Exiting/Entering Overlap settings allows the operator to avoid gaps in coverage by adjusting the amount (in meters) of entering and exiting coverage overlap. If sections turn off too early while entering existing coverage, adjust the Entering Overlap setting to force the sections to remain on for an additional specified distance. Conversely, if sections turn on too late when exiting coverage, adjust the Exiting Overlap setting to force sections to turn on earlier, avoiding possible gaps in coverage.

Note: If Entering Overlap is set to 1 meter, the implement sections will stay activated for an extra meter of coverage. If Exiting Overlap is set to 1 meter, the implement sections will activate 1 meter early.

On/Off Look Ahead

On/Off Look Ahead monitors the GPS position and coverage map while considering the look ahead times to begin controlling sections on or off before the section crosses spray or no-spray boundaries. Look ahead times may help compensate for delays in the sprayer system including the time it takes for boom or control valves to open.

Note: Off Look Ahead is the amount of time before entering an already applied area or a no spray zone that the section will turn off.

Note: On Look Ahead is the amount of time before area that needs to be applied that a section will turn on.

Adjust the Off Look Ahead to determine how far (in seconds) to turn a section off.

Adjust the On Look Ahead to determine how far (in seconds) to turn a section on.

Boundary Percent Overlap

The Boundary Percent Overlap feature allows the operator to configure the percent of the boom section allowed to pass beyond the field boundary before the section is commanded to turn off.

Note: The default Boundary Percent Overlap is set to 5%, so the boom section will turn off after 5% of the section is outside of the boundary. If Boundary Percent Overlap is set to 90%, the boom section will not turn off until 90% of the boom section is outside of the boundary.

Disable Corrected Coverage

Corrected coverage is the concept of waiting for as many seconds as the lookahead value to turn on or off coverage drawing. It is enabled by default for any implement. When disabled, coverage is turned on or off as soon as the response from the node is received.

Modify Section Settings

To set up or modify section settings on an implement:

Select the Machine Panel icon in the bottom left corner of the Street Maps view to display the available machine configurations.
Select any of the profile buttons for the machine or implements that are desired to be configured.
Select the larger machine icon near the top of the screen. The General Information tab of the selected machine or implement will display.
Select the Equipment tab.
Select the:
- Add button to create a new section group and use the on-screen keyboard to enter a group name or description for the new group.
- Edit button to modify group and section settings for an existing section group.
Note: If no section groups are configured, the Add button will be displayed in the first group.
Select the General Information tab.
Select the Name field and enter the desired name or description of the section group.
Select the Type drop-down field and select the type of sections in the group.
Enter any applicable information to be shown with the completed job or field report in the lower portion of the General Information tab.
Select the Measurements tab.
Configure the overall offset of the implement (e.g. spray boom, spread pattern, knives or shanks, etc.) from the center of the machine or implement pivot point as necessary.
1. Select the left/right offset direction and select the offset distance field and use the on-screen keypad to enter the distance from the center of the implement pivot point to the center of the section group. Refer to Equipment Setup - Measurements Tab for additional information on measuring the implement offsets.
2. Select the aft offset distance field and use the on-screen keypad to enter the distance from the center of the implement pivot point to the center of the section group. Refer to Equipment Setup - Measurements Tab for additional information on measuring implement offsets.
Select the Sections tab.
Select the Number of Sections field and use the on-screen keypad to enter the number of sections in the group. ROS will update the sections display with the appropriate number of sections.
Select a section indicator to display section settings.
Select the section label field and use the on-screen keyboard to enter the desired label (up to three characters) for the section.
Select the Width field and use the on-screen keypad to enter the section width in inches [centimeters].

Note: ROS is capable of calculating section offsets for standard implements automatically. For standard section configurations (e.g. sections aligned end-to-end and centered on the swath midpoint) set the section width for each section and touch the “Calculate Offsets” button.

Section offsets may still be adjusted to customize the section configuration as necessary.
Select the Wired As field and enter the appropriate “boom sense” connection or lead used to sense the section status. Refer to the ROS Device Installation Manual, the Raven CANbus Installation Manual, or contact a local Raven dealer for additional assistance with section connections and cabling.
Repeat step 13 through step 16 to set the section settings for each section in the section group. Once the section labels, width, and wired as settings are configured, ROS may be used to automatically calculate and set the section offsets for the group.

Calculate Section Offsets

To automatically calculate section offsets:

Verify that the section width field for each section in the group has been entered correctly.
Select the Calculate Offsets button to automatically align sections end-to-end along the swath midpoint. ROS will calculate and set the offset values for a standard section configuration (e.g. similar to sections on a self-propelled sprayer).

Configure/Adjust Section Offsets

To manually configure or adjust section offsets:

Select the left/right direction setting and select the appropriate offset direction.
Select the left/right field and enter the offset distance.
Select the fore/aft direction setting and select the appropriate offset direction.
Select the fore/aft field and enter the offset distance.

View Section Groups

The section groups feature of ROS provides a flexible method for configuring sections for various implement types. Section groups may be configured for separate “boom systems” or to group various boom sections as necessary. For example, section groups may be used to configure a tiered boom system, setup control sections on a row crop planter, or to separate implement sections on a multi-bin air seeder system with liquid booms.

Note: ROS uses the section groups to determine the overall implement or working width when providing swath guidance during field operations. For assistance with modifying the width used for implement guidance, refer to Machine Configuration Tab.

To view configured section groups:

Select the Machine Panel icon in the bottom left corner of the Street Maps view to display the available machine configurations.
Select any of the profile buttons for the machine or implements that are desired to be configured.
Select the larger machine icon near the top of the screen. The General Information tab of the selected machine or implement will display.
Select the Equipment tab.

Note: When using an implement profile assigned to a machine configuration, use the page navigation at the bottom of the tab, or swipe across the screen, to access additional implement profiles without backing out to the machine configuration panel.

The Equipment tab displays the name or description, type, and overview of the configured sections and section labels for any configured section groups.
Select the:
- Edit button to access or edit additional section group or individual section settings. Refer to the Modify Section Settings for more information on modifying section settings within section groups.
- Delete button to remove a section group from the machine or implement.
- Add button in the next available group to add a new section group. Use the on-screen keyboard to enter a group name or description for the new group and refer to the Modify Section Settings for assistance with section settings within section groups.
Note: The Edit and Delete buttons will only display for configured section groups. If no section groups are configured, the Add button will be displayed in the first group.
