Coperion K-Tron Introduces KCM-III Feed Controller

Coperion K-Tron, Niederlenz, Switzerland, a provider of compounding and extrusion systems, feeding and weighing technology, bulk materials handling systems and services, has introduced the newest generation of the time-tested KCM feeder controller.

The newly redesigned KCM-III has a variety of new features, including a larger five-inch LCD screen with an improved user interface, context-sensitive help, stainless steel enclosure and built-in Ethernet capability with optional Wi-Fi. With Ethernet capability (wired or wireless) the KCM-III can be accessed via a user-friendly feeder web page that includes a full feature user interface. In addition, the KCM-III is ready for Internet 4.0 functions, such as predictive maintenance, electronic service options, overall equipment effectiveness, outlier detection and machine optimization.

The KCM-III controller combines the motor drive and control modules of a feeder and its ancillary components into one component and is generally mounted directly at the feeder, pre-wired and pre-tested at the factory. All motor setup, diagnostics and operator interface functions are integrated into the KCM-III user interface. Each KCM-III includes a complete software package to support a wide variety of application types, both batch and continuous, from loss-in-weight feeders to weigh belt feeders to Smart Flow Meters. The KCM-III controller is rated for ATEX 3D environments and listed for NEC Class II Division 2 hazardous areas.

The KCM-III also features a new, powerful CPU with extended memory to allow for the storage of more log and event files, trace and process data. Seven days of traceability are included as standard but extended traceability is available as part of an optional software bundle. Improved control algorithms provide faster communication with the feeder drive, weighing system and auxiliary equipment, and result in more precise control of the system. In combination with our latest generation of SFT (Smart Force Transducer) load cells the KCM-III offers a significantly higher weighing resolution – 8,000,000:1 in 20 ms. Together this results in better short-term feeding accuracy as the controller reacts quickly to changes in the system. In addition to built-in flash memory the KCM-III stores all key files on a micro-SD memory card. The data files are all PC-readable, making downloading or updating files simple. Files are accessible via Web, Wi-Fi, FTP, USB flash drives or offline via the micro-SD card.

KCM-III controllers equipped with the optional Wi-Fi Gateway create their own local area network. This Wi-Fi access point allows an operator with the proper login credentials to access any or all connected KCM-III controllers using a phone, tablet, laptop or other mobile device to control the feeder remotely, check its status or access files. The KCM-III uses multi-factor security methods to ensure no unintended access occurs over Ethernet or Wi-Fi. In addition, USB ports are provided for easy connections to flash drives or laptops to transfer files, perform diagnostics or update software. Connectivity to customer PLC and DCS systems is provided via a KCM-III host port communications module available in the widely used Profinet and Ethernet/IP protocols, as well as many others.

The KCM-III currently supports over a dozen languages, including graphical languages such as Japanese, Chinese and Korean. The keypad features user-friendly and language-independent icons.
