Instructions for Initial Startup of Ag Leader Lightbar
Beginning April 1, 2002, the instructions for initial startup of the Ag Leader Lightbar
have changed slightly. These changes apply to all Lightbars with the model number of
21A that are used in conjunction with an PF Series monitor (PF3000, PF3000 PRO and
PFavantage) running version 4.20 and lower. This model number can be found on the
serial number tag on the bottom the Lightbar and should read AgGPS 21A Lightbar.
If the Ag Leader Lightbar does not have this model number, this product bulletin can be
disregarded and the instructions detailed in the Lightbar Manual should be followed as
usual.
1. Before hooking the Lightbar to the GPS unit, the Lightbar Status setting must be
turned ON in the PF monitor. To turn on the Lightbar, press the MENU button until
you see SETUP on the bottom of the screen and press this button. Locate and press
the GPS button (may need to scroll left or right) on the bottom of the screen. A
screen similar to the one pictured below should now be displayed.

2. Lightbar status should now be highlighted. Press the EDIT button and use the up or
down arrow to change this setting to ON (Do Not
time).
3. Now plug the Lightbar into the GPS connection.
4. After plugging in the Lightbar, press ACCEPT on the PF monitor. The Lightbar
should now be ready for operation. Refer to the Lightbar Manual for additional setup
and operational instructions.
If you see EZ-Guide displayed on the Lightbar or it prompts you for a swath width, the
process was not completed correctly and should be tried again. It is important to plug the
Lightbar in first, before you press the Accept button. If you still encounter problems,
please contact your local Ag Leader dealer or our Tech Support department at (515) 2325363 ext. 1.

IMPORTANT: The Light Bar must be mounted inside the cab
of your vehicle. The Light Bar is not resistant to weather
elements on the outside of the vehicle and could be damaged if
mounted outside of the cab.
1. Determine a location on the dash or ceiling to mount the Light Bar.
The Light Bar should be positioned within your peripheral vision.
2. Use an upright position for dash mounting and inverted for ceiling
mounting.
NOTE: Mounting the Light Bar on the ceiling inverts the Light Bar
text and requires a SETUP change.
3. Mounting the Light Bar bracket may be done by using three
methods: Dual-Lock strips, mounting hardware or the Optional
Suction cup. Select one of the methods below to mount the
bracket.
a. Bracket mounting with Dual-Lock strips:
(1) Clean the surface of the mounting location with
provided alcohol swabs.
(2) Remove the peel off strip from the Dual-Lock strip
on the back of the Light Bar bracket.
Do not touch the adhesive surface of the strip.
(3) Press the Light Bar bracket to the mounting location
determined in Step 1. Press the bracket firmly or
gently pound on the bracket to bond the adhesive
strip.
NOTE: The two additional Dual-Lock strips are for
replacement of the bracket strip or to add additional
mounting locations in the cab.
b. Bracket mounting with hardware:
(1) Using the mounting bracket as a template, mark the
three bracket holes for the position you determined
in Step 1.
(2) Use a 3/16-in. drill bit to drill the holes.

center of the swath will be represented by one
LED. The second LED will represent two feet
etc.
Scaled – Sets the first 10 LED’s each side of the
lightbar on a linear scale. The outer 7 LED’s on
each side are scaled to represent an end value
setting.
LED Spacing: This setting establishes LED spacing distance. If the
setting is 3 feet, the LED slides one unit to the left or
right for every 3 feet off line.
NOTE: The smaller the LED spacing the more precise
guidance the lightbar will provide.
End Distance: This setting is used when in Scaled for LED Spacing
Mode. You cannot set an end value smaller than the
LED spacing multiplied by 17 (there are 17 LEDs on
each side of the lightbar.

General Information
Auto: Automatically increments in the direction
turned after the first swath. The swath
increments when the vehicle turns more than
110 degrees.
Right: Swaths are manually incremented to the
right of the A-B line.
Left: Swaths are manually incremented to the left
of the A-B line.
Snap: Automatically increments swath
number to the closest swath. (Not availabe
with Pass Skip and Curve following.) This is
the default setting.
Swath Width: Adjust in .5 ft increments from 1 to 999 ft. Set the
swath width to 1 ft less than the actual swath width to
reduce skip. Set the swath width 1 ft more than the
actual swath to reduce overlap.
Antenna Offset: The distance from the antenna, ahead or behind the
spray boom so that guidance information is
referenced to the spraying boom instead of the
antenna. It is adjusted in .5 ft increments from 0 to
100 ft. The antenna must be placed along the
vehicle’s centerline. Negative numbers are used for
a boom in front of the antenna, positive numbers are
for a boom behind the antenna.
Pass Skips: Adjusted in 0 to 99.
Units Displayed: Determines whether Metric or US Standards
(English) are used. The default is Metric.
Contour Log Interval: The settings are Swath Change and Heading
Change. Heading change is the default and
recommended setting. With the Contour Log
Interval set to Heading Change a reference
point will be logged whenever the heading
changes slightly.

General Operation

Line
Using Headlands
Using Light Bar
with PF Series
monitors
The following are general operation information to aid you in the use
of the Light Bar.
When using curve following pattern, guidance is provided parallel to
the previously driven swath.
While driving a swath, the GPS receiver records the swath location.
When the swath is incremented, positions logged are offset in the turn
direction. Guidance begins down the offset positions. Meanwhile,
new positions are logged for the current swath. When the swath
increments, the new positions are offset and guidance begins down the
next swath. The cycle repeats until guidance is reset.
Because of limited memory capacity, only the positions representing
the current and next swath are stored. Positions representing previous
swaths are deleted.
To help operators anticipate upcoming turns; a turn signal has been
added to the Light Bar. As turns approach, the lightbar illuminates in
the turn direction. The more LEDs illuminated, the sharper the turn.
The turn signal indicates a swath turn at twice the look-ahead distance.
By default, the turn signal occurs six seconds before the turn is
required.
Headlands specify field zones that have specific meaning. In some
applications, it may be an area where chemical application is not
desired. In other applications, the headland can be used to turn
equipment and move to the next swath. Its most simple function might
be to indicate the end of swath.
Power up the PF monitor.
Press the MENU key until OPTIONS is displayed and press OPTIONS
key.
Under OPTIONS press the LIGHTBAR key. (See Figure 10)
The key settings perform the following functions:
SET A: Sets the beginning of the first swath.
SET B: Sets the end of the first swath.
