WARNING –
To avoid potentially serious personal injury or illness, and to prevent damage to
equipment, make sure that you read and understand the
chapter.
1. Make sure the emergency stop switch
is not depressed
. If the switch is depressed, the SAM-200
motor
will not communicate
with the Trimble display and the EZ-Pilot system will not engage for
auto steering.
2. Make sure that the IMD-600 unit is solidly mounted. If the IMD-600 unit vibrates, the SAM-200
drive motor will oscillate when engaged, causing the anti-rotation pin to damage the rubber
grommet.
3. Update the Trimble display, IMD-600 unit, and SAM-200 motor to the latest firmware from
http://www.agpartners.trimble.com
or from

4. Configure the EZ-Pilot system through the Trimble display.
Depending on your machine type, the following items must be calibrated
before
you can use the
EZ-Pilot system for autosteering:
– IMD-600 unit mounting orientation
– Antenna height, Antenna to axle offset, and Roll offset
– Machine type, Machine Wheelbase
– Angle per Turn left, Angle per Turn right
– Motor Speed, Override Sensitivity
EZ-Pilot calibration tips
• Configure the Trimble display to show travel speed on the map view screen.
• Adjust the Angle per Turn value within ±3 degrees of the calculated calibration value for your
machine may make a subtle improvement in steering accuracy.
• If the EZ-Pilot system consistently steers to one side on an AB line, adjust the left or right side
freeplay individually. Use values of 0.1 - 0.2 to balance the steering accuracy either side of the AB
line you are following.
• If the EZ-Pilot system exhibits a swimming motion while engaged, the IMD-600 unit may be
experiencing subtle vibration. Pick a different mounting location and/or hard mount the IMD-600
unit using the screws and spacers provided and then check if the IMD-600 mounting calibration
that is selected in the Trimble display is correct. You may need to recalibrate the IMD-600 roll
offset.
• If the anti-rotation pin is bouncing against the rubber grommet or if the steering column is
shaking,
reduce the motor speed, or the approach aggressiveness
,
or the steering acceleration
limit
.
