Simple operator interface

Powerscreen has announced improvements to the automation and control systems in its crushing and screening equipment. It implemented a wide ranging upgrade to its plant control system in 2011 as part of redesigning its machines to comply with Tier 4i/Stage IIIB legislation.

In earlier iterations in the mobile cone crusher range, the system had a multiple controller set-up with different interfaces for engine, cone setting, choke control and machine power. With the latest upgrade, all engine and machine functions are controlled and operated on a single, intuitive, human machine interface (HMI) colour display.

The menu interface and display provide the operator with a balanced amount of process detail for any task, from tracking the machine to crusher setting to full plant operation. An operator can access more detailed information through a secondary menu in the set-up, diagnostics and alarm settings menu, which helps identify and resolve faults. Within the screening range, the HMI provides improved diagnostic capabilities such as fault log history, electronic engine information and fault code support, while retaining fault icons for shutdown and de-rate warnings. A small programmable logic control inside the display panel houses the main operational software.

The aligned rollout of these systems with Tier 4i/Stage IIIB-compliant Powerscreen machines means the 1000 Maxtrak, 1000SR and 1300 Maxtrak cone crushers and some Warrior and H-range screens already include the new plant control with HMI display. The same models with Tier 3/Stage IIIA engines will be upgraded soon.

In Australia, Powerscreen is distributed by the Lincom Group.
