  • - EasyServe PC program for convenient commissioning and service 
  • - High operating convenience, automatic calibration programs

 

Application

Designed for feeding duties in continuous processes, the INTECONT Tersus measuring, control, and supervisory electronics is specially suited for single feeders and small gangs controlled by a host system. The system is the right choice whenever bulk solids have to be fed with high accuracy with the use of

  • - Belt weighers (MULTIBELT®or weigh belts with controlled prefeeders
  • - Weighfeeders (MULTIDOS®)
  • - Coriolis mass flow feeders (MULTICOR®) [in 2012]
  • - Loss-in-weight feeders (discharge and fill weighing with MECHATRON®/ AccuRate) [in 2012]

Without expensive control of the feeder environment. The system can also be used in special applications, i.e. inthe hazardous area. [in 2012].

The measuring, control, and supervisory electronics is specially economical if the feed system is controlled locally in normal mode or from the display and control panel in a central control room.

 

Equipment

The electronics is supplied as front-ofpanel mounting unit or with an optional wall-mounting housing for installation at site. The system is operated via an ergonomically styled keyboard organised into operating and service functions. The
colour LCD-display shows clearly measuring values and status information.
Equipped with appropriate communication module, INTECONT Tersus optimally fits into any automated environment. The Ethernet network connection is included in the basic equipment.

 

Operating Principle

Although the INTECONTTersus functions vary with every scale type, the basic equipment is always the same:

  • - System accuracy for weighing tasks better than 0.05 %
  • - Precise speed acquisition
  • - Optimal feed control for accurate batching via an adaptive control circuit
  • - High electromagnetic compatibility
  • - Galvanically isolated outputs
  • - Fail-safe data memory
  • - Integrated diagnostics and self-testing functions
  • - Preset with default values for easy and quick commissioning
  • - User language in German, English, Italian, Spanish and French. More languages loadable including Chinese or Russian (Cyrillic)
  • - Automatic calibration programs, theoretical span calibration without auxiliaries
  • - Configurable and selectable display modes
  • - Simulation mode for testing and learning
  • - Status, event, calibration and quantity reports

 

Weighing Functions

The difference of set and actual feed rates, determined by comparison, forms the control output to the feeder control circuits. As a function of feeder type, a corresponding control signal is transferred to the speed-controlled weigh belt, the controllable discharge unit of the loss-inweight feeder or the controllable feed unit of the Coriolis mass flow feeder. The control circuit exactly controls the actual feed rate for setpoint. The actual feed rate is acquired using:

  • - Measured variables, i.e. belt speed and belt load with weighfeeders
  • - Loss in weight in the hopper per unit time with loss-inweight feeders
  • - Direct mass flow measurement on the Coriolis principle (mass flow feeders)

In addition to the comprehensive basic equipment, the following weighing functions are available:

  • - Weighfeeders
  • - Control for point of discharge
  • - Automatic belt run monitoring (belt slip, belt skew)
  • - Belt influence compensation (BIC)
  • - Loss-in-weight feeders
  • - Adaptive fuzzy disturbance auto elimination
  • - Fill control as a function of time and/or weight
  • - Adaptive control adjustment to material properties
  • - Coriolis mass flow feeders
  • - Manual and automatic zero setting
  • - Prefeeder control
