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, anyon e coul d
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 pers onal comput er.
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 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.
