4. INSTALLATION and PRECAUTIONS
4-1. Precautions for Installing the Indicator
Ground the indicator so that the user will not be subjected an electric shock.
Do not handle the main power cord with wet hands.
The AC plug is not water-resistant. Install it in an area where it does not get wet.
Do not install the indicator where there is flammable or corrosive gas present.
Do not install the indicator under water.
Do not pull, fold or arrange cables forcibly.
Use shielded cables for all connections.
Ground the platform to be connected to the indicator to avoid a risk of electric shock.
Read the section “CAUTION” in the instruction manual of the FS-ito
understand the conditions and precautions for installation, operation and
cleaning the indicator.
4-2. Load Cell Connections
Solder the load cell cable to the connector plug (1JMNJW-165-PM7) provided with
the FS-D and connect it to the connector on the bottom of the FS-D.
1. Use the supplied hexagonal wrench (1.27 mm / 0.05 inch) to loosen the setscrews A
and B to disassemble the connector plug.
2. Put the load cell cable through each parts of the connector taking care of their order
and directions.
3. Remove the sheath and wire covering of the load cell cable referring to the drawing
below.
The external diameter of the applicable load cell cable is Ø5.7 ~ Ø6.8 mm.

4. Solder the wires to the pin contacts of the connector.
A 5 m or less load cell cable is recommended as the
FS-D uses a 4 wire system (no remote sensing).
5. Reassemble the connector plug
and tighten the setscrew A.
6. Move the load cell cable back
and forth and around, and tighten
each parts again. Finally, tighten
the setscrew B.
7. Connect the connector plug to the
load cell connector on the bottom
of the display pod.
4-3. Verifying Load Cell Output and Input Sensitivity
The input sensitivity is 0.2 µV/division or more. When designing a weighing scale, the
load cell output voltage should satisfy the input sensitivity of the indicator. Or the scale
should be designed so that the following calculating formula is satisfied.
In order to achieve a scale with stable performance, select the input sensitivity as
large as possible.
Calculating formula:
A : Rated capacity of load cell (kg)
B : Rated output (mV/V)
d : Min. display (smallest of kg) / scale division
E : Excitation voltage (mV) = 5000 mV for FS-D
n : Number of load cells
Example of calculation:
In the case of designing a scale with a capacity of 60 kg, using a load cell with a
rated capacity of 100 kg and rated output of 1 mV/V:
Load cell capacity: A= 100 kg
Rated output: B= 1 mV/V
Set function setting C02-3, then
Min. display (smallest): d= 0.005 kg
Excitation voltage: E= 5000 mV
Number of load cell: n= 1

7. CALIBRATION
This function adjusts the scale (indicator) for accurate weighing.
Calibration must be done when the FS-D is initially connected to a load cell (base unit).
Calibration may also be required according the changes in the environment.
When the scale (indicator) has been moved.
When the ambient environment has
significantly changed.
For regular calibration.
Loose the lock screws on the rear side of the
display pod, and remove the (CAL) switch
cover. The calibration switch inside.
7-1. Calibration using a weight
1. Warm up the indicator with a weighing platform connected for at least half an hour.
Change the user function setting “f01” or place something on the platform to
disable the auto power-off function.
When turning the power on and the indicator may display ------- ,
press the PRINT/ENT key to proceed to the weighing mode.
2. Press and hold the calibration (CAL) switch until
Cal appears, and release the switch.
Press and hold the 0 key for about 5 seconds, then you
can also enter the calibration mode (when “C01-0” is set).
Press the ON/OFF key or (CAL) switch to exit without
calibration.
3. Press the PRINT/ENT key, then the gravity
acceleration value will be displayed.
 It is not necessary to set the gravity acceleration value
when calibrating the indicator with a calibration weight
at the place where it is to be used. (See the next
section about the gravity acceleration correction.)
4. Press the PRINT/ENT key, then Cal 0will be
displayed.
5. Make sure that there is nothing on the platform, and wait
until the STABLE indicator turns on.
6. Press the PRINT/ENT key. The indicator inputs the
zero point, and the display shows 5pn 1and the
weight value for calibration (SPAN calibration).
 The weight value is equal to the capacity. When you
enter with “kg” or “g” mode, then the value is “kg”.
Entering with “lb” or “oz”, then “lb”.

If you need ZERO calibration but do not need SPAN
calibration, turn the power off to exit from the calibration
procedure.
7. To calibrate with a different weight, change the
displayed value using the 10-key pad.
If you enter the wrong number, press the C key. The
value returns to the capacity and enter the number again.
8. Place a calibration weight on the platform with the same
value as displayed, and wait until the STABLE indicator
turns on.
9. Press the PRINT/ENT key. The indicator calibrates
SPAN and end will appear. Remove the weight
from the platform, and turn the power off.
 Note
The value set in step 7 will be cleared after the power is switched off.
If the indicator will be moved to another location, set the gravity
acceleration value for the current location and calibrate the indicator
according to the procedure above. See the next section to set the value.
7-2. Gravity acceleration correction
When the indicator will be moved to different place from the calibration location, it
should be calibrated using a calibration weight.
But if a calibration weight is not available, the gravity acceleration correction will
compensate the indicator. To use this function, set the gravity acceleration value to the
value of the location where the calibration will be done. Refer to the gravity
acceleration map appended to the instruction manual of the FS-iseries.
1. At step 3 of the previous section “7-1. Calibration using
a weight”, enter a new value using 10-key pad.
The integral part “9” is fixed, enter the value after the
decimal point.
If you hit the wrong number, press the C key. The
value returns to the original number. Enter the number
again.
2. Press the PRINT/ENT key, then Cal 0will be
displayed.
3. Go to step 5 of “7-1. Calibration using a weight”.

8. AUTO-TARE FUNCTION
The FS-D has an auto-tare function to be used with the comparator function enabled.
If the weight value is within the OK range and stable for a preset time, then the
indicator will automatically tare the weight and show zero. The Function “f22”
designates the timing to tare automatically. See “9. ADDITIONAL INFORMATION”
about the added F-Function settings related to the auto-tare function.
To use the auto-tare function, set the function settings below.
f08-1: Compare all weighing data (other settings may be used depending on
the application).
f21-1: Auto-tare function enabled.
f22-0 ~ 9: Select the timing to tare automatically to avoid the wrong tare
operation, for example; too early to tare, to take a longer time to go to
the next weighing and so on.
Take-away check weighing:
Take-away check weighing (negative comparison) is the way to compare the
negative weight taking away material from a container. Set the Function “f24-1”
together with the auto-tare function enabled “f21-1”. In this operation mode, the
indicator operates as “take-away the material” Æ“OK and stable” Æ“auto-tare” Æ
“take-away the material” Æ······.
In this setting, the polarity of the target weight and the upper / lower limit weight are
ignored and the indicator shows the comparator results as below.
Note To start the take-away check weighing, be sure to use the TARE key to tare
the weight of the container filled with material. The ZERO key may zero the
display, and the indicator goes below the zero point by taking out the material.
Then, the auto-tare function does not work.
When the Function “f23-1 Tares the initial (container) weight.” is set:
To start the auto-tare function application, usually the container (filled with material) will
be placed on the weighing pan and its weight must be tared using the TARE key.
When the Function “f23-1” is set, the indicator will tare the initial (container) weight
automatically.
Remove all load on the weighing pan to return to the zero point, the tare weight will be
automatically cleared. If the indicator could not return to the zero point because of a
zero shift, press the ZERO key to clear the tare weight.
If the indicator is equipped with the optional RS-232C interface, the OK weighing data
only can be sent out automatically. Set the Function setting “f06-7 Auto-print mode
+/- data”.

The frame ground and the shield are connected internally and there is no difference
between them in use.
Multi-connection with Print key mode (new function)
This is one of the applications when a PC and more than one FS-D are connected.
The indicator will prepare the weighing data by pressing the PRINT key first and will
send out the prepared data after receiving a command from the PC.
1. Set the Function “f06-5” for all of the indicators.
2. Weigh something and wait for the STABLE indicator to turn on (the indicator having
f18-##).
3. Press the PRINT key, the indicator will temporarily store the weight data and turn
the PRINT indicator on.
The indicator does not accept the PRINT key while the PRINT indicator on.
4. Send the “@##S” command to the indicators from the PC.
5. The indicator (f18-##) will respond to the command to send the weight data in
memory and turn the PRINT indicator off.
The address ## = 23 (f18-23).

10. ERROR MESSAGES
Overload error
Warning to indicate that an object beyond the weighing
capacity has been placed on the weighing pan. Remove
the object from the weighing pan.
Power-on error
Warning to indicate that an object beyond the power-on
zero range (50% of the weighing capacity or 10%) is
placed on the weighing platform. Remove the object from
the weighing pan.
Pressing the PRINT/ENT key, the indicator will show
the weight value without zeroing the indicator.
Low battery
Warning to show that the OP-02 battery is discharged.
Immediately connect the power cord to the AC power
source to charge the battery. The indicator can be used
while the battery is charging (except when the OP-04 is
installed).
CAL error
Warning to indicate that the calibration has been
canceled because the calibration weight is too light.
Check if the calibration weight is correct.
Other errors
Showing errors inside the indicator. Check the
connection between the indicator and platform, and turn
the power off and on with nothing on the weighing
platform. (# signifies an error number.)
When the indicator does not recover from errors or shows other errors, contact your
local A&D dealer.
