Centurion control system

The Centurion electrical control system provides superior performance, monitoring, and data integration capabilities.

The supervisory controller, with direct integrated communication with the motor drives, allows precise motor control and fast cycle times. Real-time multi-tasking capability means optimal machine logic sequencing, monitoring, and control.

The I/O system uses the Profibus communication protocol for seamless integration of all drill subsystems. Low-voltage 23V DC I/O drop points feature open- and short-circuit detection for improved diagnostics and troubleshooting.

The graphical user interface features intuitive, icon-based screens that display vital information, including shovel status, troubleshooting information, and optional production monitoring data and operator feedback.

PreVail remote health management system

The PreVail remote health management (RHM) system provides timely and efficient machine health and performance data. The PreVail RHM system taps into the powerful communication, command, and control capabilities of the drill’s electrical control system, transforming the data into valuable knowledge, including KPI (key performance indicator) dashboards, graphical analysis tools, predictive modeling, and reporting tools.

When you activate PreVail RHM on your 320XPC drill, you have access to:

  • Increased asset performance visibility to help you determine when to intervene, minimizing corrective action costs
  • Valuable risk management tools that help reduce troubleshooting time and mean time to recovery
  • Key performance indicator (KPI) benchmarking that makes performance gaps more visible and allow you to set in motion corrective measures to maximize productivity
  • Operating practices analysis that allows you to review and correct operators that are not following best practices for optimal productivity

The initial subscription period of one year is included free; after one year, subscription fees apply.
