Figure 1 ‐ HOME SCREEN A – Joystick Selection and Activation Button Signifies the PTO is not engaged and the joystick is inactive. Upon initial system power up, press once for the JOYSTICK FUNCTION SELECTION SCREEN (Figure 2) to appear. Signifies the PTO is engaged, but joystick remains inactive. Press once to activate the joystick and the button turns Green. PTO is engaged and joystick is activated. Press once to deactivate joystick (Back to Red). NOTES: Upon each initial system power‐up and PTO engagement, the button will begin as Red until the initial joystick activation (Button to Green). After the initial activation (Red to Green), the button will toggle between Blue (Inactive) and Green (Active) based on whether the PTO is engaged. After the initial power up & joystick activation, the button, no matter the color (Blue, Red or Green), will need to be held for 3 seconds for the JOYSTICK FUNCTION SELECTION SCREEN (Figure 2) to appear. TROUBLESHOOTING TIP: If PTO is engaged and button remains Blue, check PTO sensor. The connections should be secure and proximity of the sensor to the collar should be within a 1/8”. ...

Figure 1 ‐ HOME SCREEN B – Wand Depth Indicators The wand depth indicators show the instantaneous values of the left and right hand wands. These values are used to achieve the target depth (Figure 1 – F). PLEASE NOTE: If either the LH or RH indicators lose complete movement or do NOT appear to be tracking the target depth (Figure 1 – F), re‐calibrate the wands. (See “M” – Page 7) If the problem continues after re‐calibration, check rotary position sensors for damage. C‐ “LOWER HITCH” Button This button lowers the hitch incrementally. It functions in two different increments, small and large, dependent on whether the PTO is engaged. If the PTO is not engaged (non‐harvesting) and the button is pressed, the hitch cylinder will move smoothly in a larger increment. If the PTO is engaged (signifying harvesting) and the button is pressed, the hitch cylinder will move a small increment each time the button is pressed and will deactivate the “AUTO” mode. D‐ “RAISE HITCH/END ROW” Button This button has dual functions. This button raises the hitch incrementally. And, if this button is held for 3 or more seconds, it goes to “END ROW” mode and raises harvester to its maximum height. PLEASE NOTE: It works on the same increment and operating premises described above for the “LOWER HITCH” Button. ...

Figure 1 ‐ HOME SCREEN E – “–” Button This button decreases the target digging depth in increments of 0.2 inches. F – Digging “Depth” Indicator This indicator shows the target digging depth of the ADC unit when it is run in “AUTO” mode. Currently, Figure 1 – F shows a current target depth of 3.4. PLEASE NOTE: The target digging depth is an arbitrary number. The default Wand setting from factory will attempt to set target digging depth close to what the actual digging depth measures. By adjusting the wand height (See “Wand Adjustment” – Page 12), you can change the relationship between the target digging depth and actual digging depth to your satisfaction. G – “+” Button This button increases the target digging depth in increments of 0.2 inches. H – “AUTO” Button This button initiates the “AUTO” mode. It turns Green when engaged. I – Axle Cylinder Height Indicators The Orange bars on the left and right indicate the instantaneous height of the axle cylinders. The axle cylinders will vary +/‐ 2 inches from the axle cylinder setpoint. The maximum differential between the cylinders equals 4 inches. Pressing either of the axle cylinder graphics (Figure 1 – I) will put you into the AXLE CYLINDER SETPOINT SCREEN (Figure 3 – Next Page) ...

HYDRAULICS: The modulated valve can be run either open or closed center. The valve comes standard with a closed center plug. Provide the modulated valve 16‐18 gallons per minute (GPM) to run the ADC system. The case drain line comes from the rear valve section. This line needs to be plugged into the tractor’s case drain. There is a relief valve in this loop to ensure the valve will be relieved in the case that the line becomes disconnected from the tractor for any reason. Wand Adjustment: Loosen bolts A and use adjustment rod (bolts B) to adjust the height of the wands. (Ref Figure 8 below). Figure 8 – Wand Height Adjustment Note: From factory, dimension C is 5.25 inches. Tractor Cab Connections: Use the stripped Black (Ground) and Red (Positive) wire from the tractor harness provided and connect to the tractor battery power. ...
