Potential Applications
 

Boom Functions

  • Controlling boom functions with a closed-loop PWM signal for excellent proportionality and fine metering
  • Input modules to convert discrete and proportional analog sensor into CAN

Rated Capacity Limiter (RCL) / Load Moment Indicator (LMI)

  • Display boom configuration, actual load, and rated load
  • Provide function lockouts when operating in unsafe conditions
  • Allow user to define additional envelopes to further define safe working areas
  • Utilize HED smart dataloggers to record unsafe operation events

Outriggers

  • CAN based keypad to simply the wiring for driving your outriggers

Cab Function

  • Broad line up of displays to integrate engine and vehicle controls and diagnostic information
  • Keypad for the cab to control lighting
  • Engine and Transmission Control
  • Ability to monitor the engine and transmission

Misc Functions

  • Smart Dataloggers up to 8GB with optional Wi-Fi communication to log critical events
  • Fleet management via a fully functional Telematics system including the ability to download in application code remotely to the vehicle
  • High current power modules to drive lights and wiper (up to 40 amps per output)

Future Flexibility

  • User friendly software to allow you to modify and update your control system as required 

Advantages

Cost Effective

  • Distributing the vehicle controls will significantly reduce wiring harness and slip-ring costs
  • Reduced Installation Cost
  • Lower Cost of Ownership
  • Reduced Warranty Cost
    • Reduced wiring
    • Robust products

Increased Performance

  • Closed-loop current control (up to 5mA accuracy) for fine metering and a smooth swing/ slew

Improved Efficiency

  • Ability to coordinate functions (lift, extend, etc.)
  • Ability to coordinate subsystem (hydraulic, lighting and powertrain) to maximize fuel efficiency

Enhanced Flexibility

  • User-friendly software allows you to modify functionality in the field
  • Telematics allow you to download new functionality remotely from the web
  • CAN based, distributed system allows module to be added quickly to the system
