INTECONT PLUS Weighfeeder Operation Manual
1: - Overview
1: - Overview
What Is The INTECONT :
INTECONT PLUS is designed as a measuring and evaluation system for
Belt Weighers
Solids Flow Meters
Mass Flow Meters
Mass Flow Feeders
Weighfeeders
Loss-in-weight Feeders
The system is supplied in 3 variants:
1.Without option card (standard)
2.With option card VFE 610V for additional input/outputs and printer
3.With option card for Fieldbus
VSS021V: Modbus/S5
VPB 020V: Profibus
VCB020V: DeviceNet
This manual applies to control systems equipped with a conveyor belt.
1. Weighfeeder Control fo feed rate via a belt speed
2. Belt weigher with controlled pre-feeder Control of feed rate via belt load
3. Belt weigher with constant load Control of belt load via belt speed

Some Definitions:
I - Feed rate in kg/h or t/h Material amount discharged from a conveyor belt per unit time
P - Feed rate setpoint in kg/h or t/h
Z - Amount fed in kg or t Amount fed = feed rate x feed time
V - Conveyor belt speed in m/s
Q - Belt load in kg/m Weight or material on one belt meter
Gravimetric: Controlled mode
Volumetric : Uncontrolled mode
Y - Controller output in mA
Measuring principle:
Belt load Q and speed V are continuously measured and multiplied with one another. The result is feed rate I used to determine the amount fed out.
I = Q 。 V 。 3600 I in kg/h
I - Feed rate in kg/h or t/h Material amount discharged from a conveyor belt per unit time
P - Feed rate setpoint in kg/h or t/h
Z - Amount fed in kg or t Amount fed = feed rate x feed time
V - Conveyor belt speed in m/s
Q - Belt load in kg/m Weight or material on one belt meter
Gravimetric: Controlled mode
Volumetric : Uncontrolled mode
Y - Controller output in mA
Measuring principle:
Belt load Q and speed V are continuously measured and multiplied with one another. The result is feed rate I used to determine the amount fed out.
I = Q 。 V 。 3600 I in kg/h
Q in kg/m
V in m/s
Measuring Technique:
➤ Precision AC voltage amplifier with continuous correction of zero point and range.
➤ Highly resolving analog-to-digital converter. The integrated method is designed to efficiently suppress mains voltage interferences.
➤ 16-bit microcontroller
➤ Unlimited storage of counter readings configuration and calibration data.
The schematic below shows all inputs and outputs.
L/C ➤ Load cell used to acquire belt load Q
D ➤ Speed transducer
S ➤ Belt circuit sensor for automatic belt influence compensation BIC (not always present)
M ➤ Drive motor
24 V ➤ Power supply
MIN ➤ Relay output for lower limit values
MAX ➤ Relay output for the upper limit value
ALARM ➤ Relay output for ALARM
DEV. ➤ Relay output for DEVIATION fault
START/STOP➤ Start / stop scale
ACK ➤ Acknowledge event message
SET ➤ Analog setpoint
SERIAL ➤ Printer and a host computer
ON ➤ Scale is active. Outputs for control of belt and pre-feeder drives, a connection of totalizing counter and analog display unit are available.
RELEASE ➤ Release
2: - Operation
Power ON
During power failure
all counter readings
counter pulses still to be output
preselected normal displays,
Service values,e.g. ON-time
are stored for an unlimited time.
The internal clock continues running for approx. 5days.
After power-up, an automatic display and lamp test is performed, followed by the display version number, then by normal displays.
Message E1
reports power failure.
The message can be configured as an ALARM or WARNING.
ALARM:
Red lamp 
symbol E1 flash.
Acknowledge message before starting scale.
WARNING:
Signal lamp 
remains dark,
symbol E1 does not flash.
No acknowledgment. Start scale manually or automatically.
Signal Lamps
MIN (red) MIN LIMIT VALUE
lit if feed rate limit value is exceeded down.
MAX (red) MIN LIMIT VALUE
lit if feed rate limit value is exceeded up.
READY: The two green signal lamps light and no Alarm is available.
Normal Display
Upper Display
Left Rotating point as running message.
Scale is started, amount fed out and feed rate are acquired.
In STOP state (point stands still) only belt load and belt speed are measured.
