AccuWeigh™ Introduction
• Real-time Access to Information – Increase Productivity– Reduce Maintenance– Prevent Overloads
PLC Based
• Integrated directly with machine control system… NO BLACK BOXES
• No proprietary equipment• “Off-the-Shelf” hardware
– Industrial durability– High Availability– Low Maintenance Training – Simplified Troubleshooting
Unprecedented Accuracy
• 20 parameters are measured and stored on a cycle or truck basis
• Sampled at 20-50 times a second• Error correction
– Tightline– Acceleration– Motor field variation– Loop Unbalance
• Highly accurate position resolvers are more accurate and durable than older encoder technology
Flexible Operator Interface
• Any PLC interface terminal• AccuWeigh™ standard panel
– PC touch screen using RSView– 12 Inch VGA– Readable in direct sunlight
Easy Access to Information
• Data is collected and stored in a non-proprietary database– Retrieved manually from machine– Optional- telemetry to mine office
• “Data Packet” provided to mine dispatch systems

Increased Productivity
• Spot performance trends with excavators and operators– Operator Performance– Excavator Performance– Excavator Faults
• Operators receive immediate feedback from operator interface system
• Timely feedback for operators and management is essential to increasing performance and productivity
Powerful Reporting Tools
• Web Based Reporting– Viewable from a standard web browser– Can be exported to Excel– E-mail reports on a schedule– Quick-pick, one-touch reports– Custom configuration of reports
• Site specific reports available
Downtime Detection
• AccuWeigh system detects downtime and prompts operator for a reason– Productive, Down, and Delay time is
accounted for and reported in AccuWeigh Database
Alarm and Trip Reporting
• Optional alarm and trip database• Tracks time and duration of specific alarms
from PLC• Allows tracking of faults and identifies
maintenance problems and trends• Allows faults to automatically enter down
codes into machine chronology report
Blasting Effectiveness
• Tracking bucket fill energy, bucket fill time, and load weight– Allows dig index creation energy/ton that can be tracked
by time or machine location– Evaluate blasting patterns and practices
Unparalleled Support
• 24 hours - 7 days a week worldwide
• Telemetry allows upgrades and improvements to be installed remotely
• Not limited to AccuWeigh– PLC troubleshooting– Remote X-Y for regulator performance
