Optimal Fuel Efficiency: The harness is integral to systems like Auto Idle and Engine Speed Control (ESC), which reduce engine speed during inactivity, directly lowering fuel consumption.
Precision Control: Enables the Load Sensing Hydraulic System and Electronic Pump Control, which precisely match hydraulic flow to demand, improving efficiency, controllability, and productivity.
Implement Power Settings: Allows the operator to select work modes (e.g., Power, Standard, Fine, Heavy Lift) via the monitor. The harness carries this signal to the ECMs, which reconfigure engine and pump settings for optimal task performance.
Safety and System Integration:
Integrated Safety Shutdowns: Connects critical safety switches (e.g., emergency shutdown, hydraulic lockout) directly to the main control system, ensuring immediate machine response for operator safety.
Proactive Monitoring: Continuously transmits data from monitoring sensors (coolant temperature, hydraulic oil level, etc.) to the display in the cab, providing the operator with early warnings to prevent potential damage.
This 421-2680 platform harness is used for 320D2 323D2 326D2 329D2 330D2 excavator.
