INSTALLATION

Step 1:
GPS antenna
a. Mount the antenna on the
highest part of the vehicle. Ensure that there are no obstructions in the way of the GPS antenna.
b. Mount the antenna along the
boom centerline as shown below.
Note – Ensure that the vehicle with the GPS antenna on top can safety fit through the door of the machine shed!
Mounting the antenna

Step 2:
Lightbar and remote keypad
a. Attach the suction cup to the
lightbar. Mount the lightbar for comfortable viewing inside the cab.
Note – The lightbar can be mounted upside down.To flip the text, change the MOUNT setting to CEILING.
b. Mount the remote keypad for
comfortable access.
Boom centerline
a. Attach the cables as shown
below.
b. Place the cigarette lighter
plug into the vehicle’s cigarette lighter adaptor.
c. Optionally, connect the
Sonalert alarm.

Step 4:
Test your installation
a. Drive outside and turn on the
unit. The lightbar display should illuminate.
Note – GPS does not work indoors.
b. Press –/+ to change the
swath widt h, then press Enter to accept.
c. Wait for the SET A message

SWATH PATTERN OPTIONS

The following table lists the swath pattern options and describes the approach LED colors and operation.
Pattern Tips on using this pattern Diagram
NEW A-B
NEW A+
NEWCURVE
To set a straight guidance line, set new A and B points.
If you have set area points, this area is used for headland approach LED color.
Use A+ pattern for irregular gaps in your field, or for adjacent parallel fields. Just reset Point A to generate a new reference line that is perfectly parallel to the last A-B line.
With this pattern, if you have set area points, this area is used for headland approach LED color . If y ou d o not ha v e any area points, then you do not get any approach LED indication.
This option is only available if there is a valid A-B Line still in memory.
To set a curved guidance line, set new A and B points.
The approach LED does not indicate the start and end of the curve swaths. However , when you are approaching a turn, end LEDs appear as a turn signal.
Snap to Swath is not available with the Curve pattern. You must manually increment the swath. Before beginning your turn, you must press –/+.

Approach LED color
NEWHLND
For straight parallel swaths inside the headland, map at least one headland pass around the outside of the field and then set A and B points.
Before you can set the A and B points, you must complete the headland.
When you approach the he adland, the approach LED indicates your distance to the end of the swath.
Note – EZ-Guide only calculates field area based on area points, not headlands.

GUIDANCE

To obtain guidance in a field, define a reference swath by mapping A and B points. The lightbar then provides guidance at swath-width intervals. To get guidance:
Clear guidance
a. At the start of the
new field, clear old guidance points by pressing:
b. To select the desired pattern
option, press:
c. When the lightbar displays the
desired option, press:
Note – With a curve pattern, the lightbar LEDs and text only provide cross-track error (XTE) guidance parallel to the last swath. When you get past the end of each swath, they display the distance to the end of the swath.
+
• Diagrams in the SWATH PATTERN OPTIONS section on the previous page show which keys to press for each pattern option.

Approach indication

The large, central LED indicates where you are in relation to the swath line:
• GREEN – inside the spray zone. Turn the boom on when the LED turns green.
• RED – outside the spray zone. Turn the boom off when the LED turns red. For more information, see the diagrams in the SWATH PATTERN OPTIONS section on the previous page. If the HLNDWARN value is configured to greater than 0, the approach LED turns ORANGE to indicate your
approach to the spray zone boundary (from either direction). Prepare to turn the boom on or off.
Step 2:
Map the guidance line
Step 3:
Follow the lightbar
a. T urn left or right for the next sw ath. If the
next swath is not automatically selected or the wrong swath is selected, press –/+.
b. Steer your vehi cle so that you center
the green lights in the middle of the lightbar and drive forward down the swath.

Pausing guidance

You can pause guidance, for example, to refill chemical tanks or refuel.
To pause guidance … To resume guidance …
While in mid-swath, press . Press again.

CALCULATING ACREAGE

You can map area points to calculate acreage. Area points can be added in both Guidance mode and Area mode.
New Area Calculate Area View Area

1. To clear all area points in preparation for a new field, at any time press:

2. To toggle between CONFIRM or CANCEL, press:

3. When the desired option is displayed, press:

+
• To calculate the area of your field drive to each corner of the field and press: Each time the key is pressed, a new area value is displayed. The area is calculated from the outside end of the application boom.
Note – A minimum of three area points are required to calculate the field area. The maximum number of area points is 99.
The following diagram shows mapped area points and the area calculated.
• To view the field area at any time, press the following buttons until the area is displayed:
+
Actual swath pass width
Adjusted area is calculated at the outside of the swath pass
Tip – Acreage calculations take the current swath width into account, so you should drive a half-swath in from the field edge.

ALARMS

If the alarm is connected, it sounds at various times during a swathing operation to indicate that you are:
• entering or leaving the spray zone (as defined by the A-B end-zone, or by a defined headlands area)
• drifting too far off-swath (use the
• returning to the current swath while guidance is paused
• losing differential corrections (use the
XTE WARN option to configure this)
DIFF GPS option to configure this)
