13.1.5 Diagnostics Page
Figure 13 - 24 shows the diagnostic page, which is a helpful tool if troubleshooting the system is re-
quired. This screen shows you live data from the ECU that can be used to determine if or where an is-
sue might be. The following are descriptions of each of the items displayed.
- System Voltage: The system voltage is the voltage being received from the tractor. It should be be-
tween 11 and 13.5 volts.
- Wand Depth: The wand depth is the depth that the system thinks the machine is currently at based
on the wand position. When the machine is up in the air and the wands are not touching the ground,
these readings should be 0.00. If not the system needs to be calibrated, see section 13.1.8,
“ Calibration. ”
- Wand Sensor Voltage: The wand voltage is the reading of the angle sensors on the wands in front of
the machine. The voltage should be between 0.5 and 4.5 volts. As the wand is moved up and down,
the voltage should move between this range accordingly.
- Axle Position Sensor Voltage: The axle voltage is the reading from the rear axle cylinder sensors. The
voltage should be between 0.25 and 4.75 volts. As the cylinders move up and down, the voltage
should move between this range accordingly.
- Axle Height: The axle height is the current stroke distance of the rear axle cylinders. The reading
should be between 0 and 10 inches and should match the physical cylinder stroke distances.
- PTO Running: The PTO running is a simple “ YES ” or “ NO ” if the PTO is running. This is determined by
a sensor at the front of the machine, just after the PTO shaft.
