SETUP
CAUTION: AutoTrac Universal does not steer
properly in reverse for Articulated Tractors and
Windrowers. Operator should not engage
AutoTrac in reverse for Articulated Tractors and
Windrowers.
NOTE: Set StarFire height and fore/aft before adjusting
other settings.
Vehicle Type
• Row Crop Tractor—If customer is using AutoTrac at
high vehicle speeds, then they may choose sprayer as
the vehicle type
• Articulated Tractor
• Windrower
• Combine
• Sprayer
• Track Tractor
• Forage Harvester
• Cotton Harvester
Steer Wheel Speed Determines the maximum speed the
steering wheel turns to make corrections. Higher gains will
turn the steering wheel faster. Lower gains are required
for vehicles with slower hydraulic systems. The maximum
steering wheel speed increases with steer wheel speed
settings from 20 to 190. From 190 to 200 the maximum
steering wheel speed stays the same, but the rate at
which the steering wheel accelerates increases. The steer
wheel speed should be adjusted in increments of 10
between 20 and 190 and in increments of 2 between 190
and 200. Setting the steer wheel speed too high may
cause ATU unit to disengage. Adjust the steer wheel
speed as high as possible without causing
disengagements of the steering wheel.

SETUP
Acquire Sensitivity Determines how aggressively the
vehicle acquires the track. Higher gains will result in more
aggressive steering while acquiring the track. Lower gains
will give smoother entry into the next track. Setting
sensitivity too high may cause vehicle instability; setting
too low will delay acquisition. This setting affects
performance while acquiring the track only
Line Sensitivity – Tracking Determines how aggressively
ATU responds to tracking errors while the vehicle is on
the track. Tracking error is the distance between the
vehicle’s location and the desired track. Setting this
number higher will cause ATU to respond more
aggressively to match the vehicle location to the desired
track. Higher numbers will result in more aggressive wheel
motion. Lower gains may result in reduced accuracy. This
setting affects performance while on track only.
Line Sensitivity – Heading Determines how aggressively
ATU responds to heading errors while the vehicle is on
the track. Heading error is the difference between the
vehicle’s actual direction and the track direction. Setting
this number higher will cause ATU to respond more
aggressively to match the actual vehicle direction and
track direction. Higher numbers will result in more
aggressive wheel motion. Lower numbers may result in
reduced accuracy. This setting affects performance while
on track only.
Curve Sensitivity Determines how aggressively ATU
responds to a curve in the track. If the tractor is turning
inside of the curve, this number should be set lower. If the
tractor is turning outside of the curve, this number should
be set higher. This setting affects performance in curve
track only.

StarFire Height (in.) Enter the height of the StarFire
receiver. Height is measured from the ground to the top of
the dome.
StarFire Fore-Aft (in.) Enter the Fore-Aft measurement.
This is the distance from the fixed axle of the vehicle to
the receiver. The fixed axle is the rear axle on a row crop
tractor and sprayer or the front axle on an articulated
tractor, windrower, combine, forage harvester, and cotton
harvester. For track machines this measurement shall be
0. The receiver must be at or in front of the fixed axle for
all machines except articulated tractors where the receiver
needs to be behind the front axle.

Operator Presence Select a seat switch or operator
activity monitor to detect operator presence.
Disengagement Force Determines distance operator is
required to move steering wheel to disengage. High
setting will require more steering wheel motion before
disengagement. Use high setting when rough conditions
cause frequent disengagement of AutoTrac Universal.
SETUP
Steer Play Some vehicles may have excess play in their
steering system which allows the steering wheel to be
turned without change in the vehicle direction. This setting
will control the distance that the steering wheel turns in
order to take up this excess play. When ATU is placed on
a machine that has excess play this setting should be
used. This number should be set higher on vehicles which
require greater steering wheel movement before the
steering system responds. This setting should only be
used on vehicles with excess play in their steering
system. This number should be set to 0 on most vehicles
except windrowers.
IMPORTANT: Use AutoTrac Universal only on
Approved Vehicles – see
www.StellarSupport.com for list of
approved vehicles
It is important that the operator stay
seated while vehicle is moving.
When seat switch is chosen the
external seat switch must be plugged
into the AutoTrac Universal wiring
harness. If operator leaves the seat for
more than 7 seconds AutoTrac will be
disengaged.
When activity monitor is chosen
AutoTrac Universal will look for
operator activity every seven minutes.
Operator will get a time out warning 15
seconds before AutoTrac will
disengage. Pressing resume will reset
activity monitor timer.

When operating in curves, start with the curve sensitivity
equal to the optimized acquire sensitivity.
These recommended settings are a good starting point for
most vehicles. Each setting can be adjusted to try and
optimize performance. Operator may need to readjust line
sensitivity - heading and line sensitivity - tracking for best
results. Increase or decrease settings to change
aggressiveness as desired. If system is not responsive
enough, increase sensitivity settings. If desired
performance is not achieved, see TROUBLESHOOTING
section for more detail.
Step 1: Optimize Steer Wheel Speed
• Tune speed by operating parallel to and 1.2 m (4 ft) off
of the A-B Line.
• Engage AutoTrac Universal and observe performance.
• Tune steer wheel speed down until the system no
longer disengages while acquiring the line.
Continued on next page
OUO6050,0001AFB –19–20MAR06–1/5

PN=11

SETUP
• While tuning, adjust in increments of 10 between Steer
wheel speeds 20 – 190 and in increments of 2 between
190-200.
• In general, optimum performance will be achieved when
steer wheel speed is set at higher settings.

Acquire Sensitivity Too Low
Step 2: Optimize Acquire Sensitivity
• Tune speed by operating parallel to and 1.2 m (4 ft) off
of the A-B Line.
• Engage AutoTrac Universal and observe performance.
• Tune Acquire Sensitivity until machine acquires the line
smoothly.

Line Sensitivities Too Low
Step 3: Optimize Line Sensitivity
A: Line Sensitivity—Tracking
SETUP
• Tune line sensitivity tracking while operating on the A-B
line.
• If machine wanders too far from the A-B line adjust line
sensitivity – tracking higher.
• If machine becomes unstable around A-B line adjust
line sensitivity – tracking lower.
B: Line Sensitivity—Heading
• Tune line sensitivity heading while operating on the A-B
line.
• If the front of the machine wanders too far from the
track direction adjust line sensitivity – heading higher.
• If machine becomes unstable adjust line sensitivity –
heading lower.
NOTE: Line Sensitivities work together – If both are set
too high the vehicle will become unstable. If both
are set too low, the vehicle will wander around the
A-B line

Curve Sensitivity
Curve Sensitivity Too Low
• Tune Curve Sensitivity while operating in Curve Track
• If vehicle turns outside of the curve adjust sensitivity
higher
• If vehicle turns inside of the curve adjust sensitivity
lower.
Steer Play
• Steer Play is only used for vehicles that have excess
play in the steering system.
• If overall performance is unacceptable due to high play
in the steering system, adjust steer play setting higher
until effects of loose steering system are minimized.
• If Steer Play is set too high, system will become
unstable.
