DISOCONT® Tersus Measurement, Control and Supervisory System

Application

DISOCONT Tersus is a modular system for controlling continuous weighing and feeding applications. The controller is used wherever bulk solids need to be measured, fed or batched with the use of: Loss-in-weight feeders

(measuring/feeding) Weighfeeders Mass flow meters Solids flow meters Belt scales Weighing hoppers

The DISOCONT Tersus is easily integrated into the automation structures of a plant using the built-in Ethernet interface or optional fieldbus modules.

Equipment

The DISOCONT Tersus electronics consist of a main VCU and multiple optional expansion VCU’s. Because of its modular design approach, a cost-effective system configuration is achievable.

Central unit VCU for all measurement and control functions with interface to operator panels and expansion VCU’s

EasyServe-PC-program for commissioning and service

Fieldbus communication modules plug into the VCU for transfer of all relevant data to the user’s control system

Additional expansion VCU is for discrete I/O and provides expanded control of the scale system

Operator panel with graphical display and touchscreen for operation of the scale and/or parameter modifications Integrated web server for browser

server access to logs, HMI and service information

Local control station for manual operation of motors to assist with setup and maintenance

Compatible with DISOCONT Master Group Controller, see data sheet for further details

Optional access via LAN, WLAN and Bluetooth

The internal DISOCONT Tersus communication bus permits a flexible arrangement of the VCU’s, locally or in cabinets. All modules can be replaced with no need for recalibration and reconfiguration.

Technical features for all weighing and feeding systems System accuracy for scales better

than 0.05 % (DIN EN 61143-1); Resolution of the weight signal: 24 million parts Galvanically isolated inputs/outputs Non-volatile process data retention Factory presets for easy and

quick commissioning Interfaces are multilingual,

selectable and loadable Status, event, calibration, and

batch reports Batch control with adaptive

accuracy improvement algorithm Simulation mode for testing

and learning

FunctionsDISOCONT Tersus is designed to acquire the actual feed rate, ex. [lb/h, t/h, etc.] via: Belt load and belt speed for belt

scales and weighfeeder applications Changes in weight of material in

weigh hopper per unit of time for loss-in-weight feeders

Reactive force for solids flow meters

Direct mass flow measurement using the Coriolis force for mass flow meters

The load of the feeding screw with automatic calibration via a check hopper for screw feeders

The VCU precisely controls the actual feed rate to match the setpoint. Depending on the type of scale, DISOCONT Tersus routes a control signal to a:

Speed-controlled weighfeeder drive or the drive of the feed helix Controllable loss-in-weight feeder

discharge unit Controllable solid and mass flow

feeder prefeederIn a batch mode, the DISOCONT Tersus feeds a preset amount of material and then automatically stops feeding at the end of the batch. The system has learning features which use the batch results for automatic adaptive accuracy improvement.
