(reduce by 0.05V each time), till the processes of left turn and right turn are
almost symmetrical. The final degree of asymmetry should be no more than 0.1°.
When the commissioning is completed, switch the slide block from “Auto” to
“Manual” and touch “Send” button to exit from the steering sensitivity
commissioning.
5.5.4.3
Common Problems and Troubleshooting During the
Calibration of Left/Right Jump-off Voltage
When the engine is started, the guide wheel does not move or move only by small
amplitude no matter how the cursor of left/right jump-off voltage is adjusted or even
when it is adjusted to 5V at the maximum.
Throttle up the engine and observe if the guide wheel has any movement. If yes,
set the left/right jump-off voltage to an arbitrary value of 2.5V~2.8V. If not, go to
step b).
Throttle up the engine, drive the tractor to move at a low speed (It is
recommended to be no more than 0.5/s to prevent any possible danger) and
observe if the guide wheel has any movement. If yes, set the left/right jump-off
voltage to an arbitrary value of 2.5V~2.8V. If not, go to step c).
Throttle up the engine press the action button of the hydraulic valve manually and
observe if the guide wheel has any movement. If not, refer back to section 3.3 to
check if the hydraulic valve is correctly installed.
5.5.4.4
Common Problems and Troubleshooting During the
Calibration of Steering Sensitivity
No matter how high the steering sensitivity is, the guide wheel does not move.
Throttle up the engine and observe if the guide wheel has any movement. If yes,
perform the steering sensitivity commissioning as normal. And consider to
increase the steering sensitivity to 0.4~0.6 during the process. If not, go to step b).
Throttle up the engine, drive the tractor to move at a low speed (It is
recommended to be no more than 0.5/s to prevent any possible danger), and
observe if the guide wheel has any movement. If yes, perform the steering
sensitivity commissioning when the tractor is moving forward at low speed. And
consider to increase the steering sensitivity to 0.4~0.6 during the process. If not,
go to step c).
