4 Today's Presentation AccuWeighΤΜ Payload Monitoring Motor Field Control Boom Protection PLC Control Upgrades Performance Monitoring

5 AccuWeighΤΜ Introduction Real-time Access to Information Increase Productivity Reduce Maintenance Prevent Overloads

6 PLC Based Integrated directly with machine control system No proprietary equipment Off-the-Shelf hardware Industrial durability High Availability Low Maintenance Training Simplified Troubleshooting

7 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 Modular Mining Aquila/ Caterpillar Minestar

8 How It Works Cycle Detection Payload Weighing Write To Database

9 Write To Database AccuWeighΤΜ Database Dispatch Database Bucket Dumped Signal from PLC Truck Loaded Signal from Dispatch Read Data Parameters from PLC to PC Write Data from PLC to Dispatch Write Data to Database Transmit Data via Dispatch Telemetry Transmit Data via Telemetry

10 Info. Passed to Dispatch (Specified by End User) Payload of truck # of buckets Fill time of truck (seconds) Propel time (seconds) Boom jacks for that truck

11 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

12 Powerful Reporting Tools Web Based Reporting Viewable from a standard web browser Can be exported to a variety of popular file formats reports on a schedule Quick-pick, one-touch reports Custom configuration of reports Site specific reports available

13 Flexible Operator Interface Any PLC interface terminal AccuWeighΤΜ standard panel PC touch screen using RSView 12 Inch VGA Readable in direct sunlight

14 Downtime Detection AccuWeighΤΜ system detects downtime and prompts operator for a reason Productive, Down, and Delay time is accounted for and reported in AccuWeighΤΜ Database

15 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

16 Blasting Effectiveness Tracking bucket fill energy,bucket fill time, load weight Allows dig index creation energy/ton that can be tracked by time or machine location Evaluate blasting patterns and practices

17 Motor Field Control Conventional control uses fixed field or 2-step field control DCS control varies field excitation as a function of torque demand on the motion to maximize speed Reported gains of 7 to 10%++

18 DCS vs Typical Field Control Volt-Amp Plots

19 DCS vs Typical Field Controls Speed-Amp Plots

20 MF Upgrade Benefits DCS OEM %Diff Net Gain 6.5 7% in Production

21 DCS BoomPro Linear step free boom limits Simple one step limit setting procedure Bypass switch eliminates need to reset limits during rope change BOOMPRO GOEMETRY BoomPro Geometry ROPE ANGLE #1 ROPE ANGLE #2 ROPE ANGLE #3 BOOMPRO ENVELOPE RETRACT LIMIT ENVELOPE

22 PLC Control Upgrades Improves troubleshooting capabilities Increases machine reliability BoomPro Boom Protection System Provides color operator interface for alarms, limits and production data Enables motor field control and payload monitoring Provides motor stall and overload protection Enables X-Y capabilities

23 Before After

24 Improved Diagnostics

25 Cab Improvements

26 Shovel Performance Monitoring via DCS Excavator Data Acquisition System

27 Advantages of Remote XY and Chart Recording Assess performance of all mine site equipment from a central location Troubleshoot equipment problems remotely Access data from off site through dialup Improved safety for acquisition of data
