Installing the CRG-CLAAS on your CLAAS Lexion 8800 combine requires careful attention to detail. Here's a step-by-step guide to help you through the process:
Pre-Installation (Optional: CRG SIM Card): If your CRG-CLAAS unit has a cellular modem, install the SIM card before proceeding. Note that once the CRG is installed, the SIM card cannot be changed without removing the unit.
Mounting the CRG: Mount the CRG unit on the front center of the cab roof exterior using the supplied mount. Ensure the CRG is level when the combine is on level ground.
Installing the Mounting Plate: Remove the plastic eyebrow panels. Then, install the CRG mounting plate using the provided bolts and locking nuts.
Accessing Interior Panels: Open the necessary interior plastic panels as indicated in your manual. This will provide access for cable routing.
Routing the CRG Cable: Carefully route the receiver connector through the cab ceiling. Connect it to the CRG unit. Make sure the cable is securely routed and attached.
Mounting the JD Display: Use appropriate mounts to connect your John Deere display. Note that the display mount is not included in the CRG kit and needs to be purchased separately.
Setting Up ISObus Apps: Load the CRG and Bridge ISO applications onto your John Deere monitor. Follow the specific setup instructions for the Lexion 8800 combine.
Configuring the Bridge App: Enter the correct settings into the CRG-Bridge ISO application, specifically designed for CLAAS machines.
Setting Up the ISO Window Mask: Configure the window mask to display yield and moisture information on the main run pages of your John Deere monitor.
CEBIS Setup: In the CEBIS system, set the steering input source and enable the auto on/off feature.
Auto-Steer Operation: Follow the instructions to enable and engage auto-steering using the AutoTrac Pie indicator on the John Deere monitor.
Appendix A: Product Specifications: For detailed technical information, including operating voltage, power consumption, and operating temperature, consult Appendix A of the CRG-CLAAS documentation.
By following these steps, you can successfully integrate the CRG-CLAAS system into your Lexion 8800, enhancing your combine's functionality with autosteer capabilities.
