2. Outline and Feature
2.2.
The AD-4402 is the multi-function weighing indicator for batch weighing and filling
weighing. This indicator has control I/O for weighing sequence and options.
Large display
This indicator has blue vacuum fluorescent display (VFD).
The character height of the main display is 18 mm.
Current weighing data, material names, comparison references and accumulation
data are displayed in the same time.
Material names and recipe
Operation guidance
Message that assists current operation are di splayed in the fron t panel, any one could
operate the indicator without instruction manuals.
Full weighing sequences
The AD-4402 can combine plural mater i al s and the pl ain mi xture function is equipped.
Filling nozzle and agitation sequence is equipped.
Using the forecast control function, the flow control can be performed that is
equivalent to A/D conversion of 1000 times per second.
Outline and Featuressss
Outline and FeatureOutline and Feature
RS-485 interface
32 indicators can be co nnected to a pr ogramma ble controll er or a per sonal compu ter.
These protocols are according to public formats.
Options
There are built-in options of AC 250 V direct drive relay, serial interface, parallel
interface, analog output and etc.
There are built-in options of CC-Link, DeviceNet, PROFIBUS.
There are three expansion slots to install options.
Check mode during operation
The monitor mode can confirm system situation during operation.
The test mode can test Input / Output interface.
Even if there is not monitor instrument, interface can be confirmed.
Recipes and raw material data stored in the indicator
The recipe is described a combination of material codes and weights.
The material code is described th e weighi ng sequence param eters for a r aw material .
Water-resistant panel
The classification code of the front panel is equivalent to IP-65 of IEC 529 using
accessory rubber packing. The "IP-65" code is explained as follows:
IP: International Protection.
6: Against ingress of solid foreign objects.
Dust-tight. No ingress of dust.
5: Against ingress of water with harmful effects.
Protected against water jets (no powerful jets). Water projected in jets against
the enclosure from any direction shall have no harmful effects.

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.

Share the loadcell cable from noise-generating device and these power lines
beacuse loadcell signal is sensitive.
We recommend you to use the 6 wire shielded cable to prevent loss of weighing
precision.

Loadcell Output Adjustment for Zero Calibration (Zero Point)
When a message "CERR2" is displayed, zero point of zero ca libration is too large.
When a message "CERR3" is displayed, zero point of zero calibration is too small.
Use the resist er more than 50 kΩ with low (good) temperature coefficient, when
adding a resister to adjust the loadcell output to indicator terminals.

5. Calibration
5.5.
The indicator, which is connected loadcell unit, can weigh the "weight" value on the
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.
Calibration
CalibrationCalibration
Common Calibration Items
Unit The "g", "kg" and "t" or "lb" can be selected.
Decimal point The decimal point can be selected form "not used" to "four
decimal places".
Minimum division The minimum division of the weighing display.
Weighing capacity The maximum display of the weighing display.
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 "
sensitivity " of digital span.
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.
