Raven SmarTrax Calibration & Operation Manual page 51

Problem
Wheels are jittery while on-line.
System slowly oscillates while on-
line.
Machine consistently drives to the
left or right of the guidance line.
Machine consistently skips or
overlaps in the field.
The system disengages when the
auxiliary hydraulic functions
(including boom and pump
functions, raising and lowering an
implement) are operated.
Wheels do not turn fast enough in
LA mode.
Steering wheel is difficult to turn
when attempting to disengage
SmarTrax.
Steering wheel is difficult to turn
when attempting to turn the
vehicle while SmarTrax is not
engaged.
P/N 016-9001-022 Rev. D
Possible Cause
The OL Sensitivity setting is too
high.
PWM Min values are too high.
The OL Sensitivity setting is too
low.
PWM Min values are too high.
The yaw or SPS/WAS sensor is out
of calibration.
The left or right PWM Min value is
too high.
The LA Aggressiveness setting is
too low.
The OL Sensitivity setting is too
low.
Antenna is position entered in the
field computer does not correlate
with the position on the roof.
The knob on the pressure release
switch is turned out too far.
The Disengage setting is too low.
The LA Aggressiveness setting is
too low.
The pressure switch knob or
disengage setting is set incorrectly.
Load sense hose connections are
installed incorrectly.
TROUBLESHOOTING
Corrective Action
Decrease the OL Sensitivity setting
in increments of 1, allowing at least
40 seconds between adjustments.
Lower PWM Min values until the
front wheels steer very slowly
manually and with minimum
buttons.
Increase the OL Sensitivity setting
in increments of 1, allowing at least
40 seconds between adjustments.
Lower PWM Min values until the
front wheels steer very slowly
manually and with minimum
buttons.
• Recalibrate the yaw sensor to
zero while the machine is
stationary.
• Reset the SPS/WAS center
calibration.
Lower the appropriate PWM Min
value until the front wheels steer
very slowly manually and with
minimum buttons.
Increase the LA Aggressiveness
setting.
Increase the OL Sensitivity setting.
Physically re-measure the antenna
height and offset. Adjust the values
in the field computer.
Turn the knob on the pressure
switch in, if applicable.
Increase the Disengage setting.
Increase the LA Aggressiveness
setting.
Turn the knob out on the pressure
switch and/or decrease the
disengage setting.
Verify the load sense hoses are
installed correctly on the SmarTrax
valve.
