Compliance
1.1.
Compliance with FCC Rules
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radiofrequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expense.

Introduction
The AD-4407A is a weighing indicator that amplifies the signal from a load cell,
converts it to digital data and displays it as a mass value.
This indicator has the following performance:
Input sensitivity: .................. 0.15 µV/division.
Maximum display: ............... 40000 divisions.
Refresh rate of the display:. 10 times/second approximately.
Input voltage range: ............ -35 mV ~ +35 mV.
The following standard functions are available:
The HiHi / Hi / OK / Lo / LoLo limit comparison to check a mass value.
The setpoint comparison for batching applications.
The counting function for piece counting.
The preset tare function.
Four code memories to store the above mentioned data.
The accumulation function to totalize the mass values and to count the
number of accumulations.
The hold function enables weighing a living animal.
UFC (Universal Flex Coms) function to customize the protocol of outputting
data using the serial interface.
0 - 9 keys enables easy operation, such as specifying comparator
values.
IP-65 dust & water-proof stainless housing.
The following interfaces are available as options:
One interface can be installed in the indicator at a time.
An RS-232C serial interface is standard, to communicate with a computer,
printer or a remote display. This interface outputs data and can request
weight data, enter parameters and control the state of the indicator.
OP-03: RS-422/485 and 3-Relay Outputs
OP-05: RS-232C, 3-Relay Outputs and 3-Control Inputs
OP-07: Analog Output (4-20mA)
OP-08: RS-232C, Current Loop Output, 3-Relay Outputs and 1-Control Input
The calibration function includes the following functions:
Setting the minimum division (weighing interval) and the maximum capacity.
Zero and span calibration.
The weighing range function of the multi-interval weighing instrument (scale).
Digital linearization function.

Installation and Precautions
3.1.
Installation and Precautions
The weighing indicator is a precision electronic instrument. Handle it carefully.
The operating temperature is -10°C to +40°C (14°F to 104°F).
Do not install the scale in direct sunlight.
Mis-operation or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
Do not connect the power cord before the installation has been completed.
Verify that the local voltage and receptacle type are correct for your indicator.
Use shielded cables for all connections. Connect the cable shields to the shield
terminal or case as an earth terminal.
Earth ground the indicator. Do not share the earth ground line with other electrical
power equipment. ( Example: There is an earth ground terminal at the power cord receptacle. )
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is lower than 45%RH. Plastic and
insulating materials are apt to be charged with static electricity.
Even if the display is turned off, the power is on while the power cord is connected to
the AC power source.
Even if the indicator complies with IP-65, do not immerse the indicator in water.
To maintain water-proof performance, tighten the cable clamp firmly when connecting
the load cell cable or interface cable. And tighten the bolts on the rear panel firmly.
The recommended torque is 1Nm.
3.2.
Load Cell Connections
Connect the load cell cable to the terminal as shown below.
It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 are
connected, if the distance between the indicator and a load cell is shorter than
5m. At this time, use a cable with a wire having a cross-sectional area of 0.5
mm2or greater because thin cables will decrease the temperature coefficient.
The output voltage of a load cell is a very sensitive signal. Space the load cell
cable away from any noise source.
It is possible to connect eight 350ohm load cells.
The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum
current 120mA.

3.3.
Adjustment of the Load Cell Output
Caution When adding a resistor to adjust a load cell output, use a metal film
resistor in the range of 50kohm to 500kohm with a good temperature
coefficient. Use as large of a resistance value as possible in the
range in which the zero adjustment is possible. Solder this resistor
at a point near the load cell or the indicator.
In Case of Reducing the Output Voltage
When the zero output is too large, add a
resistor between EXC+ and SIG-.
In Case of Adding an Offset Voltage to the Output
When the zero output is too small, add a
resistor between EXC+ and SIG+.
3.4.
Verifying Load Cell Output and Input Sensitivity
The input sensitivity of the indicator is 0.15 µV/division or more. Satisfy the following
inequality, when you design a weighing instrument using the indicator and load cell(s).
Caution A change in input voltage sensitivity is required to cause a one
division change of the display. Select as large an input sensitivity
voltage as possible so that the weighing interval becomes stable.
Consider the leverage if a lever is used.
Weighing instrument
using one load cell.
A: Rated capacity of load cell [kg]
B: Rated output [mV/V]
D:Weighing interval [kg]
E: Excitation voltage [mV]
N:Number of load cells
Weighing instrument
using multi-load cell
Verification Example
Design:
Load cell N=1
Rated capacity A=750 [kg]
Rated output B=3 [mV/V]
Excitation voltage E=5000 [mV]
Weighing interval D=0.05 [kg]
Weighing capacity 300 [kg]
Therefore, regard the instrument as a
good design.

Installing an Option board
Caution Do not remove any screws other than described below.
Install an interface (OP-03, OP-05, OP-07 or OP-08) as follows:
Step 1 Remove the power cord from the AC power source.
Step 2 Remove eight hex bolts (one of them is the sealing bolt) from the rear panel.
Step 3 Remove the rear panel carefully as there are cables between the front panel unit
and the rear panel.
Step 4 Place the option board on the option board installation area in the rear panel
and secure it with screws.
Step 5 Connnect the option board and the main board in the front panel unit, using
the option cable.

J3 - Main board J6
OP-05 (RS-232C, I/O) J5 - Main board J6
OP-07 (4-20mA Analog output) J2 - Main board J2

Step 6 Pass the interface cable through the cable clamp to the external equipment.
Step 7 Connect the interface cable to the option board connector or terminal block.
Step 8 Place the rear panel on the front panel unit, and secure it using the bolts
removed in Step 2. The recommended torque is 1Nm.
Step 9 After powered on, enter the F-functions and store the F30 parameter,
depending on the option.
