Why does Raven SmarTrax machine consistently drive to the left or right of the guidance line?
If your Raven Farm Equipment machine consistently drives to the left or right of the guidance line, recalibrate the yaw sensor to zero while the machine is stationary and 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 and OL Sensitivity settings.
What does 'Road Mode' mean on Raven SmarTrax Farm Equipment and how do I fix it?
If your Raven Farm Equipment is displaying 'Road Mode', switch the roading switch to the on position.
Why can't I manually steer left or right from the System Diagnostics screen on Raven Farm Equipment?
If you cannot manually steer left or right from the System Diagnostics screen on your Raven Farm Equipment, check the hose connections and the node status lights for high current (HC) power. Also, check the power/ground fuses and connections and the solenoids on the SmarTrax valve for proper connection and voltage. Inspect the cable for shorts or breaks. Verify PWM Max settings are set correctly in the field computer and if you have SmarTrax hydraulic valve part numbers 334-0003-056 through 334-0003-079, verify FC adjustment is turned all the way out (typically eight or nine threads are visible beyond the jam nuts).
Why does Raven SmarTrax Farm Equipment valve makes noise all of the time?
If your Raven Farm Equipment valve makes noise all of the time, inspect the load sense orifice for blockage. If the problem persists, install the SmarTrax hydraulic valve recommended for the machine being used.
Why does Raven Farm Equipment valve makes noise in stand-by mode?
If your Raven Farm Equipment valve makes noise in stand-by mode, adjust the relief valve on the SmarTrax valve until the noise stops.
