Rev. 1.07
OPERATION MANUAL

INTRODUCTION
INTRODUCTION
The F320 is a digital indicator for a strain gauge sensor, DIN96×48mm in size.
It is best suited for quality control in production lines, including pressure load control of
pressing, pressurizing, caulking, etc., and torque control of rotating devices.
The RS-485 (protocol; Modbus-RTU) is included as standard, which facilitates introduction
into a system that is formed by using the Modbus protocol.
To take full advantage of the F320’s excellent performance and to use it safely, carefully read
this operation manual and properly understand the descriptions in this manual before use.

SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Be sure to read for safety.
In order to have an F320 Digital Indicator used safely, notes I would like you to surely follow
divide into and , and are indicated by the following documents. Notes
indicated here are the serious contents related to safely. Please use F320 after understanding the
contents well.
WARNING
CAUTION
WARNING
Misuse may cause the risk of death or serious
injury to persons.
CAUTION
Misuse may cause the risk of injury to persons
or damage to property.

SAFETY PRECAUTIONS
WARNING
●For the entire system to function safely when the F320 becomes faulty or malfunctions,
provide a safety circuit outside the F320.
●Do not modify the F320. Doing so may cause fire or electric shocks.
●Do not install in the following environments.
- Places containing corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.
●Do not connect a commercial power source directly to the signal input/output
terminals.
●Be sure to ground the protective ground terminal.
●The attached AC cable is designed for domestic use in Japan, and its rating is 125V
AC, 7A. For use at voltages exceeding the rating and for overseas use, have a
separate AC cable prepared.
●Before performing the following, make sure that no power is applied.
- Attachment/detachment of connectors of options, etc.
- Wiring/connection of cables to the signal input/output terminals.
- Connection to the ground terminal.
●For connection to the signal input/output terminals, check the signal names and pin
assignment numbers, and then carry out wiring properly.
●After wiring, be sure to mount the attached terminal block cover. Otherwise, it may
cause an electric shock.
●To take measures against lightning surge, install a lightning surge protector (optionally
available).
●Before applying power, carefully check the wiring, etc.

Warning on wiring

SAFETY PRECAUTIONS
WARNING
●Use at a proper power supply voltage.
●Do not damage the power cord. Doing so may cause fire or electric shocks.
●Do not touch any signal input/output terminal while applying power. Doing so may
cause electric shocks or malfunctions.
●If the cover of the main body is opened, it may cause an electric shock internally. Even
if the power is off, the internal capacitor is charged. Contact us for internal inspection
or repair.
●In the case of smoke, an abnormal smell or strange sound, immediately turn off the
power, and disconnect the power cable.
Warning during startup and maintenance

SAFETY PRECAUTIONS
CAUTION
●Use the F320 as it is incorporated in a control panel, etc.
●Do not install in the following environments.
- Where the temperature/humidity exceeds the range of the specifications.
- Outdoors, or where the altitude exceeds 2000m.
- Places containing large quantities of salt or iron powder.
- Where the main body is directly affected by vibrations or shocks.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●Tighten the screws for the signal input/output terminals at the specified torque.
If they are loose, shorts, fire or malfunctions may occur.
Tightening torque: 0.2 – 0.6N•m
●For sensors, external inputs/outputs and options, use shielded cables.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●If the F320 is not used by the specified method, its protective performance may be
impaired.
●When the F320 is shipped, spacers made of corrugated cardboard are used as
cushioning materials.
Though it is factory-designed so that shocks can sufficiently be absorbed, breakage
may result if shocks are applied when the spacers are reused for transportation. If you
send the F320 to us for repair, etc., take adequate measures against shocks by using
polyurethane materials, etc., separately.
●If you dispose of the product, handle it as industrial waste.

RoHS-compliant product
The parts and attachments (including the instruction manual, packaging box, etc.) used for
this unit are compliant with the RoHS Directive restricting the use of hazardous substances
with regard to adverse effects on the environment and human body.
What is RoHS?
It is an abbreviation for Restriction on Hazardous Substances, which is implemented by the
European Union (EU). The Directive restricts the use of six specific substances in electric and
electronic equipment handled within EU borders. The six substances are lead, mercury,
cadmium, hexavalent chromium, PBB (polybrominated biphenyls), and PBDE
(polybrominated diphenyl ethers).
EN61000-4-5 (lightning surge immunity)in the EMC directives applies to
the F320 body and lightning surge protector in combination.
For the connection of the lightning surge protector, see page 14.
Please inquire of our sales person about the RoHS-compliance of the option.
