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 latest generation of controllers is ready for Internet 4.0 functions such as predictive maintenance, electronic service options, overall equipment effectiveness, outlier detection, machine optimisation and much more.

The new 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 user interface of the new controller. Each controller 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 new controller is rated for Atex 3D environments and listed for Nec Class II Division 2 hazardous areas, states the company.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

The controller also features a completely 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. According to the firm, 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 the company’s latest generation of SFT (Smart Force Transducer) load cells (released in 2019) the new controller 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, mentions the company.
