Easy Mode Guidance

Introduction to Guidance

The EZ−Guide 250 lightbar uses onscreen lines, either straight or curved, to guide you. These are called the guidance lines. The most simple form of guidance line is a straight AB Line. To create an AB Line, you define a start point (the A point) and an end point (the B point). Once you define the A and B points, a straight line is drawn between them. This is your master line.

When you define the first guidance line, the lightbar copies it to create additional guidance lines.

Distance between guidance lines

When you begin to define the line, you specify the width of the implement attached to the vehicle. This width is used to calculate the distance between the guidance lines. If you do not want the guidance lines to be exactly one implement width apart, you can set an overlap or skip.

Headlands

You can record a headland boundary and get guidance to it, or you can work without a headland.

Onscreen appearance

When the main guidance screen shows the perspective view, the lines are tagged with flags that describe them.

ITEM DESCRIPTION

The master line that you created, and that the swaths are based on.

The A (start) and B (end) point on the master line. The first swath to the left of the master line. (The direction "left" is relative to the direction the

master line was drawn, not the vehicle's current position). The current swath and tag are orange.

Note: On a Pivot pattern, the swaths are numbered out from the center, not from the initial swath.

The second line to the left of the master line.

Following Guidance

The lightbar displays guidance in two places:

On the LEDs• On the screen•

Guidance on the LEDs

The term LED refers to the row of 15 Light Emitting Diodes (LEDs) that are located above the screen. The LEDs that are lit up show the position of your vehicle relative to your intended guidance line. As your vehicle position changes in relation to the guidance line, the lit LED moves left or right. Use the lightbar to obtain accurate guidance, if an implement offset or implement draft is set, or for fine guidance on straight swaths.

VEHICLE POSITION LIGHTBAR APPEARANCE

Vehicle is directly on the guidance line

The three center LEDs (green) show that the vehicle is online.

Vehicle is off the guidance line

A single lit LED has moved right. This shows that the vehicle is offline to the left.

Note: This assumes that the LED Mode is set to Chase (the default). If the LED Mode is set to Pull, the LEDs move left when the vehicle is offline to the left.

Guidance on the screen

The lightbar screen shows the position of your vehicle in the field, the guidance line, and the offline distance, so you can tell how much you need to correct your position.

ITEM DESCRIPTION

1 Offline distance 2 Guidance line 3 Vehicle position

Guidance Patterns

The EZ−Guide 250 lightbar has seven guidance patterns so you can create guidance to suit your field layout:

Straight AB

A Straight AB is the most simple form of line. Use a straight AB Line when you do not need to define headlands and you want to drive the field in parallel straight lines.

To create a straight AB Line, define a start point (A) and an end point (B). The Straight AB Line then appears as a straight line between the two points.

PATTERN EXAMPLE

Note: When the vehicle is on a guidance line, the line extends 1 km (0.6 miles) before Point A and 1 km beyond Point B. This makes it easier to see where the next swath is, and to get online after the turn.

Mapping an AB Line

Drive to the start point of the master line.1. Set the A point:2.

Press or until you have selected the icon.a. Press . The A point is set.b.

Drive to the other end of the line.3. Ensure that the icon is selected and then press . The master AB Line appears.4.

Turn left or right for the next swath. As you move toward the next swath, it appears on the screen and

5. turns orange to show that it is selected.

A+ line

An A+ line is also a straight line. It is defined by a single point on the line (the A point) and the heading of the line.

PATTERN EXAMPLE

When you choose to create an A+ line, you enter the heading.

The default heading is the same as the previous AB Line. This pattern is useful for when you need guidance exactly parallel to the last AB Line, for example when:

driving adjacent fields• mapping the AB Line on a road down the side of the field• skipping an access road in a field•

The A+ line extends 1 km (0.6 miles) before and after the A point.

Mapping an A+ Line

Drive to the start point of the master line.1. Set the A point:2.

Press or until you have selected the icon.a. Press . The A point is set. Because you have already set the line heading, your master AB

Line appears on the screen. Follow the AB Line for guidance down the first swath.3. Turn left or right for the next swath. As you move toward the next swath, it appears on the screen and

4. turns orange to show that it is selected.

Identical curve

The identical curve pattern records your exact route between the A and B points, instead of a straight line.

All of the guidance lines will match the master curve, regardless of where the vehicle has driven. Use the curve pattern when you want to work the field with gentle curves.
