Active Implement Guidance requires correct supply and return flow of hydraulic fluid for proper operation.

1. Select Application Controller 1100 Button.

2. Select Application Controller Main softkey.

3. Select SCV Threshold Setup button.

4. Extend or retract selective control valve (SCV) control lever while monitoring wheel angle sensor position value (A) and sensor voltage (B).

   • SCV extend (implement moves right during forward travel): Wheel angle and sensor voltage increases (Example: voltage from -5.0 to -1.0).
   • SCV retract (implement moves left during forward travel): Sensor voltage decreases (Example: voltage from -1.0 to -5.0).
   
   

   If SCV extend or retract results in wrong wheel angle or sensor voltage direction value, swap hydraulic lines.

5. Record sensor voltage with SCV in:

   • maximum left position (SCV retract).
   • maximum right position (SCV extend).
   • center position. Center voltage = (Maximum left position voltage plus maximum right position voltage) divided by 2.
   
   

Adjust wheel angle sensor position if:

• Implement does not travel straight at calculated center position voltage value.
• Difference between center position voltage and maximum left position voltage is less than 1 V.
• Difference between center position voltage and maximum right position voltage is less than 1 V.
