★A&D’s new indicator, the AD-4402 is designed for batching
operations and can also be incorporated into systems using
Field Bus such as CC-Link, DeviceNet and PROFIBUS.
★AD-4402 has almost all the functions, user-friendly operatingprocedures and software you need for your weighing system.
Hopper gate control is doneby forecast control mode with
1msec-high speed response.

Incorporates
Recipe and Mixing modes.

Select from 50+ functions foreach of the 11 Control Inputs
and 11 Control Outputs.

Meets Fieldbus requirementsby employing CC-Link,
DeviceNet and PROFIBUS.

Features●Large and easy to see blue Vacuum
Fluorescent Display (VFD).
●Uses a ten key pad and function buttons
that are designed for ease of operation andunderstanding.
●The main display has a 7-digit VFD with
18mm tall characters.
●The subdisplay has 108, 5mm tallcharacters and shows the values and error
comments.
●Pre-programmed with multiple sequences
and functions for filling machines, simple
mixing machines and other applications.

●Stores 100 data for raw materials and 100
data for recipe codes.
●RS-485 Serial Interface standard featureallows you to link up to 32 units to thedisplay and supports the Modbus function.
●The Monitor Function shows each
operating interface and provides aconfirmation on the display.
●The compact body meets DIN
requirements, while minimizing the depthof the indicator to135mm.
●With the proper optional interface, theAD-4402 is compatible with CC-Link,
DeviceNet, PROFIBUS.

Multi-Function Weighing Indicator●Applications●AD-4402 can be incorporated in various applications that
integrate complex systems, thereby facilitating a wide variety ofsequences, such as basic filling/discharge, recipe, mixing,compensation and preliminary sequences.

Here is why we recommend ourAD-4402 Multi-Function Weighing Indicatorfor your weighing system.
★Sequential weighing mode

The sequential weighing mode directly outputs control
signals such as supply, discharge, preliminary-fullmedium-dribble flow, recipe and mixing materials andnozzle control without PLC.

★Interface monitoring function

Control I/O, RS-232C,-422,-485 I/F, Current Loop, A/D
converter, BCD output, Relay output, Parallel I/O,
Analog output, etc. can be monitored to see if they areworking correctly. You can see each interface statusvisually during operation without stopping theweighing system.

Interface Monitoring Function
Example: Control I/O★Interactive messages

Messages that assist current operations are shownon the display and allow anyone to operate theAD-4402 without an instruction manual. Just follow
the interactive setting and operating procedures on
the display. Sometimes mistakes happen. When they
do, a message is displayed so you can recognize thesituation and take corrective steps.

★Digital Span and Gravity Acceleration
Compensation

When you cannot use an actual calibration weight due
to location, just input the load cell rated output voltage
for zero point and full capacity calibration. Aftermoving the calibrated weighing system, recalibrate itby inputting the local gravity acceleration value.

★Calibrated A/D board

The A/D board is calibrated before shipment andguaranteed to 1/500 accuracy. You can quickly
replace the A/D board if there is a malfunction.

★Safety check function

Input Terminals A1 to A11 Status

This function is used to stop the sequence when anerror or an emergency occurs. When the safetyfunction is used, an error code is displayed and anerror signal is output automatically to the PLC to stopthe system. Up to eight emergency overrides can beinstalled.

Output Terminals B1 to B11 Status
Safety Check Function (Error Alarm Signal Output)★11 Control Inputs/11 Control Outputs

50+ functions (such as Full Flow, Over, Under,
Discharge Bin, Net Display, etc.) for each of the 11Control Inputs and 11 Control Outputs, depending on
the weighing system.

Troubleoccurs

Weighinghopper★Standard RS-485

32 indicators can be hooked up to the PLC(programmable logic controller), a PC (personal computer)or other equipment that supports Modbus.
This is useful for control commands input andrecalling/updating the code memory.

★Optional Field bus networking interface
boards for CC-Link, DeviceNet orPROFIBUS
To meet increasing requirements for networking withfield bus systems, there are three bus-interface options(CC-Link, DeviceNet and PROFIBUS), which can behooked up directly to the PLC units. More than twoindicators can be hooked up to the PLC at one time.

On the main and subdisplays, a Vacuum Fluorescent Display was used for easy visual
recognition. Operation keys are arranged by function for easy setting and recalling thecontents. What’s more, there are messages for each setting and function and current statuson the subdisplay. Even without an instruction manual, you can handle many emergencies.

For speedy andtimely operation,
keys are larger
and functionallyarranged.

For harsh
environment-use
such as in moisture,
water and dust
environments,
the AD-4402 display
is IP-65 compliant.

Contents by Code and setting & status
messages are displayed on thesubdisplay.

Alphanumeric input is available
using the setting input-keys.

Display example
The AD-4402’s interactive, easy to see character arrangement andgraphics are very user-friendly.
●The main display has 18mm tallcharacters and a 7-digit VFD for theweight value displays.
●The code name, code number, total,
set-point, counts, bar graph andjudgment can be displayed on thesubdisplay.
●Displays calibration, current status (likesetting procedures), error, malfunction
and trouble-shooting messages.
