3.2. Connecting the Load cell Cable
Caution
Do not share the load cell cable with noise-generating devices or power lines,
because the load cell signal is very sensitive.
We recommend that you use a 6 wire shielded cable to prevent loss of weighing
precision.
If the load cell cable length is shorter than 5 m, you may use a 4 wire shielded cablewith terminals 1 & 2 shorted (EXC+ & SEN+ shorted) and terminals 3 & 4 shorted(EXC- & SEN- shorted).

Adaptable Compression Terminal Parts

Use the appropriate compression terminal parts to attach the cables.

Load cell Output Adjustment for Zero Calibration (Zero Point)

If the message "CERR2" is displayed, the zero point of zero calibration is too large.
If the message "CERR3" is displayed, the zero point of zero calibration is too small.
Use a resistor of more than 50 k with low (good) temperature coefficient, when
adding a resistor, to adjust the load cell output, to the indicator terminals.

In Case of Positive Offset

In Case of Negative Offset

Page 12AD-44023.2.1. Verifying Load Cell Output and Input Sensitivity
The input sensitivity of the indicator is 0.3V/division or more. Adapt to the following
inequality, when you design a weighing instrument using the indicator and loadcell(s).

CautionA change in input voltage sensitivity is equivalent to a one division change ofthe display. Select as large an input voltage sensitivity voltage as possible sothat the weighing interval becomes stable.
Consider the leverage if a lever is used.

Calibration

The indicator, when connected to a load cell unit, can weigh the "weight" value on theload cell pan and display its "mass" value. The calibration function is used to adjust
the displayed value so that the weighing system can weigh correctly.
There are two ways of calibration. The "actual load calibration" uses a rated massand zero output from the load cell. The "digital span" inputs arbitrary values(calculated by hand). These methods are selected in the calibration procedure.
There is a compensation function of the "gravity acceleration correction".
This function is used, when a calibrated weighing system is moved to another place.
The calibration parameters are stored in non-volatile memory in the indicator and aremaintained even if power is removed.

6.2. Simple Hopper Scale with a Recipe CodeThis section explains the recipe code. The recipe code is used on a simple hopper
scale to mix several materials that have preset final values. "The simple hopper scale"means that it does not control the ratio or the weight of an ingredient, but simply totals
the preset final weight of the material code. Therefore, the recipe code is used to total
the preset final weight of the material code.

6.2.1.

Definition of a Recipe CodeA recipe code consists of multiple preset material codes.
A maximum of ten material codes can be stored in a recipe code.
A recipe code is used in order to total the final weight of the material code.
The AD-4402 indicator can store one hundred recipe codes.
The recipe code is necessary, to store the details before use.
The code is recalled using a code number in a weighing sequence.
The recipe code is used to total the preset final weight of the material code.
If a recipe code is used in the batch weighing (or loss-in-weigh), you can obtain aweight that is the total preset final weight of the material code.
The recipe sequence that uses a recipe code is also called a formula sequence.

6.3. System Design of a Hopper Scale
6.3.1.

Operation and I/O Design

In General, looking at an old type hopper scale design, the simplest indicator only
displayed the weight value, other system devices communicated the control signal witheach I/O interface. And the key operations and monitoring the system were controlled
separately.
The AD-4402 indicator has an I/O interface to control the system, a sub-display tomonitor system information, a main display to display weighing data and keys tocontrol the system, in one unit.
The indicator is designed so as to be able to select arbitrary keys and terminals tocontrol the system from the front panel keys and the I/O interface with the menufunction. The function of keys and terminals can be designed in the same way.
The system information of the sub-display can be selected in at the function list.

6.3.2.

Design Example

Suppose that the I/O, keys and sub-display are as follows:
Batch start:
F1 key,Emergency stop key:
F2 key,Dribble signal :terminal B1,
Batch finish signal :terminal B2,
Not used recipe code
Use default setting for the sub-display[0thf- 2] [6][0thf- 3] [13][0utf- 1] [6][0utf- 2] [14][5q f- 8] [0][5ub f 1] [0]

7.2. Batch Weighing Mode
This mode is used to obtain a (constant) final weight from a supplying hopper for thehopper scale and filling machine. And mode can be classified as normal batchweighing or loss-in-weigh.
There are two control methods of the customer programmed control and built-in
automatic program mode.

Normal Batching

Normal batch weighing weighs the material charged into the hopper.
Control gates (valves) can be used. (Full flow, medium flow and dribble flow)

Loss-in-weighLoss-in-weigh weighs the material discharged from the hopper.
Control gates (valves) can be used. (Full flow, medium flow and dribble flow)

CautionUse a PLC (programmable logic controller unit) to supply material into theweighing hopper and monitor the bulk of material in the hopper.

Selection of Batch Weighing

Selection of Normal Batching or Loss-in-weigh

The mode can be selected at Loss-in-weigh in the Function list.

terminal that is set to [9] of External switch control.
(The menu [Function] - [Function setting] - [Control I/O Function] - [Input] )Example of use: 100 kg of material is supplied to the hopper in the first step. It is
subdivided into material of 10 kg.

AdviceIf the mode is switched concerning a specified material only, set the hopper number.
in the material code, short the hopper number output line and the supply/discharge
switch input line. Set the delay timer [5q f-32] to "above 0.1sec.".

Page 38

AD-44027.3. Built-in Automatic Program Mode
The built-in automatic program mode directly outputs control signals (example:
medium flow valve, batch finish) without a PLC.
The built-in automatic program mode can include several partial sequences like an
initial flow sequence, mixing sequence etc. into basic built-in automatic programmode.
The control I/O signal output power is too small to drive large valves directly.
Use option relay output ( OP-02 ) to drive them.
If the number of control I/O terminals is not enough, use parallel option I/O ( OP-05 ).

Forecast Control Function

This function forecasts a timing to close the dribble flow (valve) and realizes more
precise weighing. The forecast method calculates the weighing value at some points
between sampling data and compares it with the dribble setpoint. The effect isequivalent to using a high speed A/D converter. The sampling rate of this indicator is
100 [times/second]. But the rate is equivalent to 1000 [times/second], when thisfunction is used.

Automatic Selection of the Supplying Hopper

When multiple supplying hoppers are used, the indicator has to control the gates of
the hoppers. There are two methods to control the gates.

Case 1: Direct Gate Control

The method that connects the gate control lines of supplying hoppers to the I/O
terminals of the indicator and the indicator directly controls them.
Three kinds of gates can be used in a supplying hopper. (Full, medium, dribble gate)
Number of supplying hoppers:
Ten hoppers can be used.
Preset material codes and recipe codes can be used.
The selection of the supplying hopper is [MatEDIT] - [Material code] - [Material hopper].
The selection of the I/O terminals is [Function] - [Function setting] - [Control I/O Function] - [Output].
Even if a code is recalled during the sequence, the code does not work until thesequence finishes.
When the number of I/O terminals is not enough, use the relay output option (OP-02)
or parallel I/O (OP-05).

Case 2: Gate Control with Supplying Hopper Selection

The method:
Parallel the gate-lines of hopper gates of a kind and connect them to the I/O
terminals of the indicator.
Make hop-lines that are identified by each hopper and connect them to the I/O
terminals.
The indicator can control any gate which the gate-line and hop-line are active. (logicalAND gate)
Three kinds of gates can be used in a supplying hopper. (Full, medium, dribble gate)
Number of supplying hoppers:
Twenty hoppers can be used.
Preset material codes and recipe codes can be used.
The selection of the supplying hopper is [MatEDIT] - [Material code] - [Material hopper].
The selection of the I/O terminals is [Function] - [Function setting] - [Control I/O function] - [Output].
When the number of I/O terminals is not enough, use the relay output options (OP-02)
or parallel I/O (OP-05).

Nozzle Control Sequence (Vacuum Cleaner)

The nozzle is used for filling a bottle with a liquid or powder. The procedure inserts thenozzle into the bottle automatically using the signal "nozzle down" before theweighing, weighs it and removes the nozzle when dribble flow is finished. Therefore,
the result (comparison) of weighing is not affected.

AdviceWhen the automatic free fall compensation cannot work.
Check the fluctuation of dribble flow.
When the error (| result - final value |) of the displayed value is greater than thisparameter, the function does not work.
Check if the dribble flow timer is too short.
When the timer is shorter than Dflow auto-FFall override [5q f-36], thefunction does not work.

When the accuracy does not improve, even if automatic free fall compensation is
used.
Check the stability of the dribble flow.
When the dribble flow is unstable and the dribble flow timer is short, the function
cannot work correctly.
When the result becomes over, even if automatic free fall compensation is used.
Remove the timer between preliminary and free fall
When the values of preliminary and free fall are near, medium flow only works toreach the final value and the dribble flow cannot work.

Page 58

AD-44027.3.14. Real Time Free Fall Compensation
This function adjusts the free fall parameter to obtain more precise weighing during
the sequence (in real-time calculation).
Example: This function fits a liquid weighing (water, cement, tar) where the flow rate is
not constant due to temperature, viscosity and the remains.

7.4. Customer Programmed Control (Comparison Output)
The "customer programmed control mode" simply outputs the comparison results ofthe setpoints and the displayed value.
The setpoint : A preset standard value to compare with the displayed value.
The comparison and output of the results are performed at each sampling time.
If this function is used, a PLC (programmable logic controller unit) is needed for batchweighing on a hopper scale.
If the control I/O signal output power is too small to drive a large valve directly,
use relay output option ( OP-02 ) to drive them.
If the number of control I/O terminals is not enough, use the parallel I/O option ( OP-05 ).

CautionInitial flow sequence and compensation sequence cannot be used in the"customer programmed control"

AdviceAutomatic free fall compensation and Total function
If the start key is used in the same as sequential mode, when three gates are closed, theEval timer has worked and the displayed value becomes stable, then the batch finish
signal can be output.
The start key is not necessary to compare displayed values basically.

7.4.1. Normal Batching of the Customer Programmed
Control Mode
This function outputs gate control signals that are derived from the compared setpoint
and weighing data of the materials totaled in the hopper.
When the weight increases above the setpoint, the gate control signal turns off.
When the weight decreases under the setpoint, the gate control signal turns on.
The weighing mode in this function is bi-directional. Therefore, the comparison isrepeatable (reversible).

7.4.2. Loss-in-weigh of the Customer Programmed
Control Mode
This function outputs gate control signals that are derived from the compared setpoint
and weighing data of the materials from the hopper.
When the weight decreases past the setpoint, the gate control signal turns off.
When the weight increases past the setpoint, the gate control signal turns on.
The weighing mode in this function is bi-directional. Therefore, the comparison isrepeatable (reversible).

Recipe Printing

Recipe printing is a function to output the results of weighing performed using thesimple recipe function to an external printer.
Use a printer in dump print mode.
Set “Communication mode” to “Auto print mode” (CLF-02=2).

Recipe printing mode

Recipe printing has three modes depending on the printer. A mode is selected in thefunction setting.
CLF-07 (Process print of recipe)
Parameter
Description0
No recipe printing
1Mode 1
For general-purpose printers and A&D 24-digit printerssuch as AD-8118A/B
The material code is printed in two lines.
The material name of 12 characters is fully printed.
The maximum number of printing characters per line is 22,
with CRLF at the end of the line.
2
Mode 2
Exclusively for A&D 24-digit printers such as AD-8118A/B
To save printing paper, the material code is printed in one
line. Consequently, the material name is printed using only
the first nine characters.

Printing the date and time

When a printer with the data and time printing function such as AD-8118A/B or
AD-8121 is used for recipe printing, the data and time can be added to the printout.
These printers will print the date when ECD (1B, 44) is received, and the time whenE
CT (1B, 54) is received.
For the date and time printing format, refer to each printer instruction manual.
The printing position of the date and time can be specified to be before the recipe
printing or after the recipe printing in the function setting.
