Introduction
Thank you very much for purchasing our Torque Monitor TM380.
The TM380 is an indicator only for our company UTM Ⅲand UTF series. Equipped with peak hold and
HI/LO limit comparison functions, the TM380 is used for a testing machine etc. (Connectable to UTMⅡ
series.)
To take full advantage of high performance of TM380, thoroughly read this operating manual first before
use and understand the explanations contained herein for correct operating procedures.Also, carefully store
this instruction manual so that it can be referred to at any time.
Safety Precautions
Installation, maintenance and inspection of the TM380 should be performed by personnel having technical
knowledge of electricity.
In order to have an TM380 Torque Monitor 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 TM380 after understanding the contents well.
BE SURE TO READ FOR SAFETY

WARNING
●For the entire system to function safely when the TM380 becomes faulty or malfunctions,
provide a safety circuit outside the TM380.
●Before using the TM380 as described below, make sure to consult with our sales personnel.
- Use in environments not described in the operation manual.
- Use greatly impacting human lives and assets, such as medical devices, transport devices
entertainment devices, and safety devices.
●Do not disassemble, repair, or modify the TM380. Doing so may cause a fire or an electric
shock.
●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.
●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.
●Be sure to use crimp contacts for connection to the terminal blocks, and do not to connect
bare wires as they are.
●After wiring, be sure to mount the attached terminal block cover. Otherwise, it may cause an
electric shock.
●Do not connect anything to unused terminal(s).
●Before applying power, carefully check the wiring, etc.
●Use a power supply voltage and load within the specified and rated ranges.
●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.
This sign forewarns the presence of hazards
that could result in serious injury or fatality
when incorrectly handled.

CAUTION
●Use the TM380 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.
- Where the temperature changes remarkably or there is a danger of freezing or condensing.
- Outdoors, or where the altitude exceeds 2000m.
- Places exposed to direct sunlight
- Dusty places
- Poor-ventilated places
- 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.
●Install the TM380 as far away from devices generating high frequency, high voltage, large
current, surge, etc., as possible. Also, carry out wiring separately from their power lines. Do
not carry out parallel wiring and common wiring.
●Do not use it, broken down.
●Tighten the screws for the power input terminal at the specified torque.
If they are loose, shorts, fire or malfunctions may occur.
Tightening torque: 0.5N•m
●For external inputs/outputs and options, use shielded cables.
●The temporary overvoltage applied to the power should not exceed 1500V.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●After power-on, make sure to warm up the TM380 for at least 30 minutes or more before use.
●If the TM380 is not used by the specified method, its protective performance may be
impaired.
●Maintenance
- When performing maintenance, disconnect the power.
- Do not wipe with a wet rag, or with benzine, thinner, alcohol, etc. Doing so may cause
discoloration or deformation of the TM380. In the case of heavy contamination, wipe off
the contamination with a cloth after dipping it into a diluted neutral detergent and wringing
it well, and then wipe with a soft, dry cloth.
●When the TM380 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
TM380 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.
This sign forewarns the presence of hazards
that could result in personnel injury or property
damage when incorrectly handled.

1-1. Main features of the TM380
●The TM380 is a simple torque monitor that can easily be connected to our torque meter
UTMⅢand UTF series (UTMⅡ) with a dedicated cable (optionally available).
●In addition to torque, rotation speed and angle can also be displayed.
●The TM380 is equipped with hold functions with respect to torque.
(sample, peak, bottom, P-P, average, and angle peak)
●The TM380 is equipped with the function of recording data according to a print command
of the SI/F (up to 30 pieces of the most recent data). Also, data can be checked on the
spot by key operation.
●The TM380's compact size of DIN96×96 realizes space-saving.
●By mounting an optional interface according to the purpose, ease of load control can be
further improved.

The following are precautions related to connection.
The precautions described here are important for safety.
Make connections after properly understanding the description.
WARNING
●Do not connect commercial power directly to the signal input/output terminals.
●Make connection to the signal input/output terminals with no power applied
because you may receive an electric shock.
●For connections to the signal input/output terminals, carry out wiring properly after
confirming the signal names and pin assignment numbers.
●Be sure to use crimp contacts for connection to the terminal blocks, and do not to
connect bare wires as they are.
●After wiring, make sure to mount the attached terminal block cover. Otherwise, you
may receive an electric shock.
●Turn on the power after carefully checking the wiring, etc.
●Do not touch the signal input/output terminals while the power is on. Otherwise, you
