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 displayed in the front panel, anyone could
operate the indicator without instruction manuals.
Full weighing sequences
The AD-4402 can combine plural materials and the plain mixture 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.
RS-485 interface
32 indicators can be connected to a programmable controller or a personal computer.
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 the weighing sequence parameters for a raw 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
PrecautionPrecaution
Precaution
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.
Separatethis earth linefrom otherground line like a motor, inverter ora 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 is broken, do not replace the fuse and contact your local
or A&D dealer. This trouble may cause of an electric discharge of thunder.
Splashing water
The indicator is not water-resistant. When the indicator is mounted 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 terminalsin theside of thepower source before removingthe
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.
