Introduction
Thank you very much for purchasing our Torque Monitor TM500.
The TM500 is an indicator only for our company UTMⅡseries. Being equipped with the waveform
comparison and hold functions, the TM500 can be used for multipurposes, such as in automatic
assembling machines, testing machines, etc.
For good performance, and proper and safe use of the TM500, be sure to read this instruction manual and
properly understand the contents of it before use. Also, carefully keep this instruction manual so that it can
be referred to at any time.
Safety Precautions
In order to have an TM500 Digital Indicator used safely, notes we 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 TM500 after understanding the contents well.
For safety reasons, please read the following safety precautions thoroughly.
WARNING
This sign forewarns the presence of hazards that could result in serious injury or
fatality when incorrectly handled.

WARNING
●For the entire system to function safely when the TM500 becomes faulty or malfunctions,
provide a safety circuit outside the TM500.
●Before using the TM500 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 modify the TM500. 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.
●Before performing the following, make sure that no power is applied.
- Attachment/detachment of each connectors.
- Wiring/connection of cables to the power input terminals.
- 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 install the attached terminal block cover after wiring to the power input terminals.
Otherwise, electric shocks may result.
●Before applying power, carefully check the wiring, etc.
●Use power supply voltage and load within the specified range and rating.
●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 TM500 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.
- Locations subjected to drastic temperature fluctuations or icing and 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 as far away as possible from equipment generating high frequency, high voltage,
large current, surge, etc. Perform wiring of cables separately from these power lines. Do not
perform parallel wiring and identical wiring.
●Do not use the product if damaged.
●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: 0.5N •m
●For external inputs/outputs, RS-232C 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.
●Use after warming up for 30 minutes or longer following the startup of power supply.
●If the TM500is 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 TM500. 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.

IV
About the Built-in Lithium Battery
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).
CAUTION
●When the TM500 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
TM500 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.
WARNING
●Never disassemble, deform under pressure or throw the battery
into fire.The battery may explode, catch fire or leak.

1-2. Features
TM500 is a torque monitor that enables waveform display of changes in torque with respect to
displacement (mainly angles), combined with UTMⅡseries with optional rotary encoder. Changes
in torque that are hard to grasp numerically can be grasped visually on waveform display.
With the color liquid crystal touch panel display adopted, twists have been provided in many places
by thoroughly paying attention to ease of understanding so that all operations can be performed
without the instruction manual. Also, having a high-speed processing capability of 4,000 times/sec
ready for fine changes in values, and being equipped with the waveform display, HI/LO limit
comparison and other various hold and judgment functions, it can be used for a wide range of
applications, such as in production control systems, automatic equipment, and testing machines.
