Application
Designed for feeding duties in continuous
processes, the INTECOUNT PLUS
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 or weigh
belts with controlled prefeeders
• Weighfeeders
• Coriolis mass flow feeders
• loss-in-weight feeders
without expensive control of the feeder
environment. The system can also be
used in special applications, i.e. in the
hazardous area
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.

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-in-weight 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-in-weight 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

Operating Principle
Although the INTECOUNT PLUS 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 (EEPROM)
• Integrated diagnostics and self-testing
• functions (SPC)
• Preset with default values for easy and
quick commissioning
• AUTO calibration (automatic
calibration programs), theoretical span
calibration without auxiliaries
• Totalizing pulse (level and pulse width
set by parameter)
• Simulation mode for testing and
learning
• Status, event, calibration and quantity
reports

Equipment
The electronics is supplied as front-of-panel
mounting unit or with an optional wallmounting
housing for installation at site.
The system is operated via an
ergonomically styled keyboard organised
into operating and service functions. A
luminescent, anti-glare two-line display
ensures easy reading of results.
Equipped with appropriate communication
module, INTECOUNT PLUS optimally fits into
any automated environment.
