2.1. Precaution
2.1.2.1.
Befor any use, confirm the following articles for the safty operation.
Grounding the indicator
Ground the indicator certainly. The earth terminal is the rear panel.
Separate this earth l ine from other g round line like a motor, inverter or a power source.
Unless the indicator is grounded, it may cause to receive an electric shock, be
happen operation error or catch fire
Use adaptable power cord
Confirm the AC voltage and current of the power cord. If the voltage range of cord is
lower than power line voltage, it may cause of a leak or catching fire. Use
compression terminals to connect the power cord to the terminal of the rear panel.
Fuse
The fuse is installed to prevent the indicator from catching fire.
The indicator is equipped many safety circuits. Therefore, the fuse is not broken in
normal operation. If the fuse i s broken , do no t repl ace the fuse and co ntac t your local
or A&D dealer. This trouble may cause of an electric discharge of thunder.
Precaution
PrecautionPrecaution
Splashing water
The indicator is not water-resistant. When the indicator is mou nted to panel with
accessory rubber, the front panel is equivalent to IP-65.
Flammability gas
Do not install the indicator in any flammable gas.
Radiation of the indicator
Space out instruments to radiate heat sufficiently.
Removing the cover
Remove the power cord terminals i n the side o f the power source before r emoving the
cover to avoid receiving an electric shock.
Do not touch the internal circuit within 10 seconds after turning off the indicator
because of receiving an electric shock.

loadcell pan and display its "mass" value. The calibration function is used to adjust
the weighing value (displaying value) so that the weighing system can weigh
correctly.
There are two way of the calibration. The "actual load calibration" uses a rated
mass and zero output from the loadcell. The "digital span" inputs arbitrary values
(calculated by hand). T hese 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 other place.
These calibration para meters are stored in the indicator without any power supply.

Items for the "Actual Load Calibration"
Common items Unit, decimal point, minimum di vi sion and w eighing capacity
Zero point adjustment A zero point output is used from the loadcell unit.
Span adjustment Rated mass is place on the weighing pan and is weighed.
The sensitivity is adjusted. This sensitivity is the same as "

Items for "Digital Span"
Common items Unit, decimal point, minimum di vi sion and w eighing capacity
Zero point output The numerical data is input as zero point output of loadcell
unit.
Rated capacity The rated capacity of the loadcell is input.
The sensitivity of the loadcell is input.
Caution
When the CAL switch on the A/D board is "DISABLE", any calibration can not
perform.
Do not perform any calibration during a weighing sequnce operation.
Entering calibration mode during a weighing sequnce operation, the weighing
sequnce operation is terminated. Calibrate the weighing system, when a
weighing sequnce operation does not work
The accuracy of the "Digital Span (Calibration without Mass)" is 1/1000.
Do not use a "loadcell summing box", the "digital span" is performed.
It is necessary that the loadcell sensitivity is exactly known, if the "digital
span" is used.

The section explains for recipe code (another name: formal function). The recipe
code is used on a simple hopper scale to mix several materials that are preset target
value. "The simple hopper scale" means that does not control the ratio and a weight
of ingredient, but simply accumulates the preset target weight of the material code.
Therefore, the recipe code is a code to accumulate the preset target weight of the

In General, looking an old type hopper scale design, the simplest indicator only displayed
weighing value, other system devices communicated the control signal with each I/O
interface. And the key operation and monitoring the system separately were controlled.
The indicator AD-4402 has the I/O interface to control the system, sub-display to
monitor system infor mation, mai n display to display w eighing data and keys to c ontrol
the system in a unit.
The indicator is designed so as to be able to select arbitrary keys and terminals to
control the system form front pan el keys and th e I/O interface w ith the men u function.
And the function of keys and terminals can be designed in the same way.

The mode is used to get a (constant) target weight from a supplying Mat for the
hopper scale and filling machine . And the mode can be classified to normal batch
weighing and loss-in weight.
There are two control methods of the custom er programmed control and sequential
control (built-in automatic program mode).
Batch Weighing Mode

Normal Batching
Normal batch weighing weighs the material charged into the hopper.
The control gates (valves) can be used. (The full flow, medium flow and dribble flow)
Loss-in-weight
Loss-in weight weighs the material discharged form the hopper.
The control gates (valves) can be used. (The full flow, medium flow and dribble flow)
Caution
Use the PLC (programmable logic controller unit) to supply material into the
weighing hopper and monitor the bulk of material of the hopper.

7.3. Sequential
7.3.7.3.
The sequential weighing mode (built-in automatic program mode) directly outputs
control signals (example: medium flow valve, batch finish) without the PLC.
The sequential weighing mode can include several partial sequences like an
approach sequence, mixture sequence and etc. into basic sequential weighing.
The power of the control I/O signal output is too small to drive a large valve directly.
Use option relay output ( OP-02 ) to drive them.
If the number of the control I/O terminals is not enough, use option parallel I/O ( OP-05 ).
Sequential Weighing Mode
SequentialSequential
Forecast Control Function
The function forecasts a timing to close the dribble flow (valve) and realizes more
precision weighing. T he forecast method calculates the weighing value at some
points between sampli ng da ta and compares it with the dribble setpoint. Th e e ffect is
equivalent to use a high speed A/D converter. The sampling rate of this indicator is
100 [times/second]. But the ratio is equivalent to 1000 [times/second], when the
function is used.
Caution
If prual supplying mat is used (the recipe code is used), the mode ca n not use.
Relation section is " 7.3.7. Automatic Selection of Supplying Mat".
Use the high speed high precision valve like a direct voltage solenoid valve.
Design the mechanical valve so as to minimize the delay time.

The "customer programmed control" simply outputs the comparison result of the
setpoints and weighing value.
The setpoint : It means the preset standard value to compare the weighing value.
The comparison and output of the result are performed at every sampling time.
If the function is used, the PLC (pr ogrammabl e log ic controller uni t) needs for a batch
weighing on the hopper scale.
The power of the control I/O signal output is too small to drive a large valve directly.
Use option relay output ( OP-02 ) to drive them.
If the number of the control I/O terminals is not enough, use option parallel I/O ( OP-05 ).
