Description:

This fault code, CLC 002050.06, is triggered when the Cab Load Center (CLC) control unit detects excessive load current: over 130 amps when the circuit board temperature is below 115 °C (239 °F) or over 100 amps when the temperature exceeds 115 °C (239 °F), for a duration longer than 2 seconds. This condition can lead to potential overheating and overloading of the circuitry, risking damage to the control unit and connected devices.

Reaction:

To manage this high current situation, the control unit’s software initiates an automated sequence to shut down individual drivers to reduce the load current. The software allows 8 seconds before it shuts down the first driver, with subsequent shutdowns occurring at 2-second intervals. The shutdown sequence prioritizes drivers based on several criteria, including exceeding fuse ratings, a predefined order of importance, and proximity to fuse ratings.

Recommendations:

• Immediate Current Reduction: Promptly reduce the number of active drivers or load to lower the overall current draw.
• Inspect and Repair Circuitry: Check the CLC circuit board for signs of damage or overheating and make necessary repairs.
• Review System Configuration: Assess the configuration and compatibility of all connected devices and drivers to ensure they are not contributing to excessive current draw.
• Regular Monitoring: Implement continuous monitoring of current levels and circuit board temperature to prevent recurrence.
• Priority Adjustment: If necessary, adjust the shutdown priorities to better protect critical components based on operational needs.
• Consult Technical Support: Persistent or unclear issues should be addressed in consultation with John Deere technical support for advanced diagnostics and guidance.

Note:

Preventive maintenance and routine checks are vital in managing the risks associated with high current levels in heavy-duty machinery. Ensuring that all components operate within their electrical specifications is crucial for safety and operational efficiency.
