Lahti offers inexpensive way to upgrade dosing controls

Supplier of industrial weighing and dosing systems for the glass industry, Lahti Glass Technology Oy has developed a new batch controller for the dosing and weighing control of raw material components for glass batch. The new instrument offers an inexpensive way to upgrade dosing controls. It is designed to replace and fit into the space occupied by the old (Raute) Lahti WB-950 and WB-951 dosing controllers – users can keep the existing control system mainly as is; there is no need to modify the PLC program or HMI but the communication protocol must be changed to Profinet.

The new Lahti batch controller’s hardware is based on Siemens standard components, and is therefore future-proof for as long as these components are available – the same applies to hardware support worldwide. Software retains all the features of the old instrument (e.g. automatic pre-act value compensation when material flow properties change) and more.

Spare parts will soon be unavailable for the WB-951 batch controller for single component dosing as it becomes obsolete. Old units such as these can be replaced with Lahti’s new controller while the batch plant is in production. Installation requires only short breaks to dismantle the existing units and to mount the new modules in the same place. New modules will be delivered ready wired and programmed.
