Troubleshooting
If there is a problem calibrating the hydraulics, review the following errors
and conditions and make the appropriate changes to allow it to calibrate.
• Gain Difference High- This error occurs if the calibration values for the
left and right hydraulics differ by too much. Try to operate the system if
the performance is unsatisfactory then recalibrate. If this error
continually occurs, there is likely a problem with the hydraulic system.
• Hydraulics backwards- This error will occur if the machine turns in the
opposite direction of what the SmarTrax expects. To fix this, reverse the
connectors on the solenoids and then recalibrate.
• Hydraulic Error- This error will occur if the hydraulics are connected
improperly or if one or both of the solenoids are disconnected.
• SPS Backwards- The SPS was calibrated backwards (i.e. left is right,
right is left). If this occurs, the SmarTrax will prompt you to reset the
SPS left center and right values and then a new calibration will be
necessary.
• Steer Switch Activated- If the steer switch is continually being engaged,
the steer pulse time can be altered. To do this, press down from the steer
switch screen. Then press the right arrow to increase the time. Press
down again to return to the calibration screen and then press the foot
switch. Also, to ignore any steer switch signals, the left arrow can be held
during calibration. If the pulse time is changed, it will be reset to the
default value of 150 ms after calibration is complete.
• Too Slow- This error appears when the speed drops below 3 mph or
when the SmarTrax looses DGPS. To continue calibration, confirm a
valid GPS signal, drive the machine above 3 mph and then press the foot
switch.
• Too Fast- This error appears when the speed rises above 6 mph. To
continue, drive between 3 and 6 mph and press the foot switch.
• Valid Points Low- If the SmarTrax does not receive enough valid data
from the calibration a new calibration will be needed.
• Yaw Backwards- If the yaw sensor is mounted improperly this error will
occur. Be sure that the yaw is connected properly and is mounted with
the flat surface parallel to the ground with the Raven logo facing up.
