2. Warning
Guide on handling for safe use
For the safe and correct use of the product, make sure to read the handling guide carefully before use.
Handling errors can cause device malfunctions, and it can lead to injury, accidents, etc.
Warning !
1) For the safety, only a worker with professional skills in electronics and electrical construction is
allowed to install the product.
2) Make sure to use the product within the rated input/output range set in the specifications.
3) Install the product in the environment of use indicated in the specifications.
4) Use the product in the permissible temperature range. If you use it outside the temperature range, it
can cause malfunctions or damage to the temperature switch, thus causing a degradation in the
safety nearby.
5) Do not apply excessive loads, vibrations, or impacts.
6) Do not let the sensor of the temperature meter to get bent. If the sensor gets bent, it can interfere
with the normal operation of the temperature meter, thus it can lead to temperature discrepancies.
7) Do not grab the head and turn it. Using a tool, hold the hexagonal screw parts to turn it.
8) O-ring can cause changes over time or characteristics change, and it can lead to a loss of
necessary functions for sealing, thus it requires periodic replacement, and in general, it is
recommended to replace it every 5 years.
9) When installing it in the site, make sure to follow the guide from the user manual.
10) Do not remodel the product itself or try to add a new function to it.

4.2 Principle of operation
4.2.1 Bimetal type
A bimetal strip is a rod-shaped component where two thin sheets of metals with different thermal
expansion coefficients are joined by welding.
The difference between expansion of the coils depending on temperature is used to measure
temperature.
The degree to which the coil is twisted is converted into temperature.
Coil type thermometers are used for industrial temperature measurement.

4.2.2 liquid filled type
1) Temperature measurement
A filled system type thermometer is comprised of a ② sensor and indicator, and a ③ capillary tube
connecting the two. The inside is filled with a gas.
When the gas inside the sensor expands or contracts due to temperature change, the change in volume
is transmitted to a ④ Bourdon tube through a conduit.
The displacement of the tube is indicated as a temperature on the ⑤ display.
2) Temperature compensation
In a temperature measurement circuit, there can be an error between the temperature of the
measurement contact point and the actual temperature of the object being measured due to
temperature fluctuations around signal-transmitting lines or conduits or thermocouple converters.
The measured temperature is corrected to compensate for error due to changes in the surrounding
temperature.
There are two methods of compensation: In the first type of compensation, the temperature indicated by
the sensor is kept from changing regardless of fluctuations in the surrounding temperature.
In the second, methods are used to offset errors caused by fluctuations in the surrounding temperature.
A compensation wire uses the first method of compensation, maintaining the temperature indicated
regardless of surrounding temperature fluctuations.

5. Installation guide
5.1 Pre-installation checks and precautions
1) Handle with care during transport, as impact due to dropping may cause damage to performance.
2) Store in locations with low humidity and without dust or vibration. When stacking, weight should
be limited to prevent deformation of the packaging boxes. Boxes should be stacked to prevent
toppling over.
3) Open packaging carefully.
4) Check the product for damage and check process conditions before installing the product.
5.2 Matters of caution for installation
1) Temperature differentials are caused by the insertion depth of the sensor. For accurate temperature
measurement, the entire sensor of the thermometer must be inserted.
2) The product is sensitive to vibration and impact.
3) If the installation location is subject to vibration or mechanical impact, install the thermometer a safe
distance away.
4) Use of a thermowell is recommended for safe use and maintenance.

5) Fasten securely using tools such as a spanner.
.
6) Holding and turning the thermometer case at installation may cause defects.
7) The bolt under the case must be loosened to adjust the direction of the indicator unit of the
thermometer. Once the bolt is loosened, the indicator can be adjusted to the desired angle.
8) Periodically inspect the installation location for moisture, vibration, dust, corrosive gas.
9) Avoid areas that might exceed the temperature ranges specified in this manual.
10) Make sure to protect from lightning or steam.
11) Avoid areas with direct sun light.

6.2 Setting method
1) Open the cover of the setting adjustment dial.
2) Adjust the setting value by pressing and turning the setting adjustment dial right or left using a flat
head screwdriver.
3) Depending on the depth to which the adjustment dial is depressed, the settings for contact NO.1 or
NO.2 can be adjusted.
4) After adjusting settings, close the cover to prevent ingress of foreign matter into the thermometer.
6.3 Cautions for wiring
1) Do not apply excessive force to the main body.
2) Use vinyl insulation cables, cap tier cables, etc., adequately for the load.
3) Make a firm connection to the terminal board using an M4 compression terminal.
4) Make sure to wire it after checking the contact point format on the wiring diagram.
5) Grounding
- Use the grounding terminal made of aluminum material for corrosion prevention.
- Use the grounding bolt made of 304SS materials.
- Use a spring washer to prevent looseness of the grounding terminal.
- After checking the joint, connect a proper grounding cable to the external grounding terminal.
6) After making a connection, check if the power supply and the signal cable are connected properly.

7. Repair and maintenance
1) Use it in a temperature that is no more than 75% of the max scale reading.
2) Do not apply temperatures out of the temperature range.
3) Avoid sudden temperature change.
4) Do not inject fuel into the driving unit within the temperature meter.
5) Periodically check the product for normal operation at least once or twice every 6 months.
6) If the setting error is big, then disassemble the product for inspection.
7) The product can malfunction due to each part's abrasion, corrosion, external vibration, or impact
that causes distortions. In this case, you need to remove the cause, make an adjustment, or
replace parts.
8) Use the rated current according to the standard in 3.1 9) but in case of the built-in micro switch, it
may differ, thus consider some margins based on the rush current within the range of rated current
for the product.
9) The micro switch's contact resistance will increase gradually as time passes. Especially, in case of
contact point operation in an environment with silicon, light load can lead to an accumulation of
SiCO2 in the contact point, thus causing a sudden increase in the contact resistance. Therefore,
make sure to ventilate properly, or use it in the clean environment. Especially, if used for inputs to
the control sequence, it can cause contact point failure, thus make sure to use the 110/220V buffer
relay.
8. Defect
1) If the indicator needle shakes, please check for the following.
à Loose fastening of connection, worn connection, vibration near the installation location.
2) If the temperature indicated by the needle differs from the actual temperature, adjust using the zero
point adjustment device on the rear face of the thermometer.

9. User's duties
1) Incorrect installation can eventually lead to an inaccurate reading of temperature.
2) During use, if one causes damage to the product due to failures to comply with the user manual, or
if one arbitrarily remodels, changes or repairs the product, the manufacturer will not be responsible
for it, and the product warranty period will expire.
3) Wise can support users’ selection but will not be responsible for them in any sort of way.
10. Product return
1) If the product gets returned for recalibration or repair work, make sure to use the original packaging
or safe packaging method, and also make sure to return the related documents.
2) Make sure to prevent exposures of the product to dust, wetness, or other sources of pollution
during the conveyance.
3) Pack it properly to prevent vibration or any kind of impact during the conveyance.
4) If the product gets damaged during the conveyance, make sure to record it on paper, and if there is
some kind of loss due to a delayed installation, one may demand compensation from the
conveyance company.
