4. Installing The Module
This section is explained for the environment to install the module and for the terminals of the
power source and load cell cable. Refer to each section of options for I/O interface.
4.1. Conditions To Install The Module
The module is a precision electronic instrument. Handle it carefully.
The operating temperature is -10°C to +50°C.
Do not install the module in direct sunlight.
4.2. Power Supply
Earth ground the module to prevent electrical shock or indicator malfunction.
Before connecting the module to the power source, read the instruction manual thoroughly.
Do not connect the module to the power source before the installation is complete.
To avoid electrical shock, do not handle the power cable with a wet hand.
Earth ground the module. Do not share the ground line with other electrical power equipment.
The power requirement is 24 DCV, +10% to -15%.
Use a stable power source free from instantaneous power failure or noise.
To avoid a malfunction, do not share the power line with other devices.
The output voltage of a load cell is a very sensitive signal. Keep all electrical noise sources
away from the load cell and load cell cable.
Use shielded I/O cables. Connect the cable shield to the F.G. terminal or the module housing.
4.3. Loadcell Cable
Load cell cables should have high insulation and shielding performance.
Use shielded cables with the insulator that is made of materials with high insulation resistance
such as Teflon and polyethylene. NOTE: Teflon is a registered trademark of DuPont. When
usingthe extension cable, we recommend usingA&D's load cell cables.

Cable diameter......................................................φ9mm
Ex. Rod crimping terminal
Illustration 4 Cable type

AD-4430B - 11 -
4.4. Shield Cable
Connect the load cell shield wire only to the shield terminal of theAD-4430B.
As a general rule, No ground is connected between the load cell and theAD-4430B. This is to
prevent the ground loop generated by multiple ground points.Aground loop can be created
along the wiring route, and interference such as high-frequency noise becomes more likely.
4.5. Connecting Loadcell Cable
Shield Cable Connection
As a general rule, only connect the load cell cable's shield wire to the module's shield
terminal. This is because when there are multiple ground points, it becomes easier for noise
to occur as a result of a ground loop. However, when there are higher priorities than noise
prevention, such as explosion prevention systems or static electricity release routes, this rule
does not necessarily need to be followed.
Load Cell Terminal Connections
Two types of load cell connection are available: 6-wire connection and 4-wire connection.
For high precision and stable weighing, 6-wire connection is recommended.
Terminal No. Terminal Name & Function
1 SIG- Load cell input (-)
2 SIG+ Load cell input (+)
3 EXC- Load cell excitation voltage (-)
4 SEN- Sensing input (-)
5 SEN+ Sensing input (+)
6 EXC+ Load cell excitation voltage (+)

(recommended)
The error is small even
when the load cell cable
is extended, a thin load

multiple load cells are
used.
Complicatedwiring Use a 6-wire shielded
cable when a summing
box is used.
4-wire

worsensthe
temperaturecoefficient.
Prone to the influence of
the contact resistance of
the connector
The error increases
when the load cell cable
is extended or multiple
load cells are used.
Precautions to be taken when using the 4-wire connection:
If the 4-wire connection has to be used, please take the following measures.
Be sure to connect terminals EXC+(6) and SEN+( 5 ) and terminals SEN-(4) and EXC-(3).
When lengthening the load cell cable, try to use cable with a large cross-sectional area.
Also, keep the cable as short as possible.
4.6. Verifying Loadcell Cable
When the load cell connection is complete, perform a connection check using the following
procedure.
Perform a visual check to ensure that the wiring is correct.
Turn the module on.
When calibration has not yet been carried out, the display value may be blank. However, as
long as there are no problems with the display, confirmation can still be carried out using
check mode.
Enter the check mode and check the load cell output value.
Refer to “7.3.Check Mode" to enter theA/D check mode.
Confirm that the displayed load cell output value matches the specified value. Normally the
displayed value will be the load cell rated output value or less.
If an error occurs, refer to "7.2. Verifying The Loadcell Connections ( DIAGNOS )" or "7.5.
Verifying The Loadcell Connections Using Multimeter".
