3. Installation and Precautions
3.1. Installation and Precautions
The AD-4406A weighing indicator is a precision electronic instrument. Handle the
indicator carefully.
The operating temperature is -10 to +40 (14 to 104 ).
Do not install the indicator in direct sunlight.
A malfunction or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
When an AC Adapter is used, please confirm 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.
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is less than 45%. Plastic and isolators are
apt to be charged with static electricity.
3.2. Power Supply
When an AC adapter is used
A stable power source must be used; an unstable power source which includes an
instantaneous noise component may result in a malfunction.
When standard batteries are used
Use six new size C batteries, preferably alkaline type.
Remove the battery cover. Press in and up on the end of the battery box. Slowly
release pressure on the battery box while holding it against the top of the battery
compartment. The battery box will slide out.
Insert the batteries into the battery box, taking care of the polarity of the batteries.
Then, insert the battery box, contact end first, into the battery compartment. Push it
in and towards the bottom. The battery box will hook onto the edge of the
compartment. Attach the cover over the battery box so that it will not fall out.
Rechargeable size C batteries can be used in place of standard batteries. For
details on how to use and charge the rechargeable batteries, refer to the battery
instruction manual.
3. Installation and Precautions

Page 6 AD-4406A Weighing Indicator
3.3. Load Cell Connections
Connect the load cell wires to the connector (receptacle), at the rear panel, using
the accessory load cell plug.
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.
The output voltage of a load cell is a very sensitive signal. Place the load cell cable
away from any noise source.
It is possible to connect four 350 ohm load cells.
The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60
mA.
3.4. Adjustment of the Load Cell Output
Caution Use a metal film resistor in the range of 50kohm to 500kohm with a
good temperature coefficient, when adding a resistor to adjust a load
cell output. Use the largest resistance value possible in the range in
which 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. Installation and Precautions
Connection available for
a cable shorter than 5 m.
(Recommended wire cross-
sectional area: 0.5 mm2or greater)

3.5. 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 in 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.
Weighing instrument
using multi-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
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.
3.6. Installing an Option Board
Caution Do not remove any screws other than described below.
This is the procedure for the interface (OP-03, OP-04, OP-05, OP-07 and OP-08).
Step 1 Remove the batteries or AC adapter from the indicator.
Step 2 Remove two screws from the rear blank panel.
Step 3 Remove the rear blank panel.
Step 4 Align the option board with both board guides and insert the board. Then the
connector between the main board and the option board will connect properly. If
the option board panel will not close completely, retry step 4 to insert the option
board correctly.
Step 5 Secure the option board panel using two screws.
3.7. Attaching the Display Stand (OP-11)
Caution Do not remove any screws other than described below.
Step 1 Remove the batteries or AC adapter from the indicator.
Step 2 Secure the stand to both slide-rails with the bolts provided.
