Basic Operation of Active Implement Guidance System

PC18001-UN-09DEC13

Active Implement Guidance — Selective Control Valve (SCV)

A - Wheel Angle Sensor

B - Application Controller 1100

C - Implement Feedback Sensor Harness

D - Display

E - SCV Control Lever

F - StarFire™ Receiver

G - Application Controller Harness

H - 9-Pin Machine Side Implement Feedback Harness

I - Implement Steering Mechanism

• Selective control valve (SCV) set to AUTO or automatic control (AC) mode. NOTE: SCV cannot change to AUTO or AC mode when machine is in park.
  
• Wheel angle sensor (A) communicates implement steering angle to controller (B) with signals carried through implement feedback harness (C).
• Implement steering angle information is calibrated by operator, using display (D) and SCV control lever (E).
• Application Controller 1100 calculates implement off-track error using StarFire™ Receivers (F).
• When a steering adjustment is required, a signal is sent from Application Controller 1100, through application controller harness (G), to machine SCV controller through implement feedback harness (H) or external valve through CAN bus.
• SCV controller communicates instructions for sending hydraulic fluid to implement steering mechanism (I).
• Process returns to first step to monitor for any implement off-track error. Constant adjustments are made to keep implement steering towards guidance line. NOTE: If using an external valve, 9-pin machine side implement feedback harness cannot be used. Disconnect harness when machine is powered off.
