1. COMPLIANCE
Compliance with FCC rules
Please note that this equipment generates, uses and can radiate radio frequency
energy. This equipment has been tested and has been found to comply with the
limits of a Class A computing device pursuant to Subpart J of Part 15 of FCC rules.
These rules are designed to provide reasonable protection against interference
when equipment is operated in a commercial environment. If this unit is operated in
a residential area it might cause some interference and under these circumstances
the user would be required to take, at his own expense, whatever measures are
necessary to eliminate the interference.
(FCC = Federal Communications Commission in the U.S.A.)
Classification of protection provided by enclosures
The equipment is designed to comply with the IP Code of IEC 60529.
The “IP65” 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.

2. INTRODUCTION
This manual describes how this product works and how to get the most out of it in
terms of performance.
The FS-D weighing indicator is used to build high performance check weighing
scales. It has similar specifications and functions as an indicator of the FS-i series.
Please refer to the instruction manual for the FS-i supplied with the FS-D.
The FS-D indicator has the following features.
The indicator can be used to build platform scales from 6 kg (15 lb) capacity to 1500
kg (3500 lb) capacity.
The indicator can drive up to 4 x 350 Ω load cells.
Three weight display resolutions are available, 1/3,000, 1/6,000 (~1/7,500) and
1/12,000 (~1/15,000) to cover various applications.
Weighing units are kg (kilogram), g (gram), lb (pound), oz (ounce), and lb-oz
(pound and ounce). However, the FS-D set to a capacity higher than 30 kg (70 lb)
does not have all of them. Refer to “11-1. Capacity and minimum display” in detail.
Waterproof to IP-65 specifications.
Constructed from stainless steel for harsh working environments.
Large liquid crystal display with back lighting and analog sweep display of 60
segments with back lighting.
AC power source (100V ~ 240V), and an optional SLA (sealed lead acid) battery is
available for operation where AC power is not available.
Built in comparator lights with large and bright red, green and yellow LEDs for better
visibility.
Two modes of comparator operation, Target weight setting and Upper / Lower limits
setting.
Take-away check weighing with auto-tare function.
Optional serial data and comparator relay interface.

3. UNPACKING
Unpack the indicator carefully and keep the packing material if you are likely to
transport the indicator again in the future.
When unpacking, check whether all of the following items are included:
Main power cord

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-i to
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.
Load cell cable
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
6. Move the load cell cable back
7. Connect the connector plug to the

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)

≤0.2

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
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
