1. General items
1.1 Introduction
The product is a temperature indicating switch contact point thermometer with a built-in indicator and
micro switch.
Before using the product, make sure to fully familiarize with the user manual that indicates how to
handle each part for the correct use.
1.2 Application
When it reaches the target temperature, the product can be used for On-Off signal-based process
control, alarm, or warning displays, etc.
1.3 Product characteristics
1) Contact point thermometers are best suited when temperature indication and switch functions are
required.
2) The contact point thermometer has separate measurement elements for indication and contact,
so the indication after switch assembly is also accurate.
3) The contact point thermometer has separate measurement elements for indication and contact,
so the indication after switch assembly is also accurate.
4) The contact thermometer is very easy to set as the indication scale and setting scale are
separately installed.
1.4 Warranty
If one causes damage to the product due to failures to comply with the user manual, or if one
arbitrarily remodels it, changes or repairs the product, the manufacturer will not be responsible for it,
and the product warranty period will expire.

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.
11) When opening the product case, make sure to turn off the power first. If you do wiring work when
current flows, there is danger of electrical shocks.

4.2 Principle of operation
As shown in the figure below, the temperature measuring element is connected to the sensor and the
capillary tube.
When the temperature changes, the gas in the sensing unit expands or contracts according to the
temperature, resulting in a change in pressure.
The displacement of the bourdon tube due to the pressure change is delivered through the rod to the
lever, thus opening and closing the micro switch.

5. Installation guide
1) Before installation, make sure to check the product for damage and the process status.
2) Periodically inspect the installation location in terms of wetness, vibration, dust, corrosive gas, etc.
3) Avoid a location with temperatures exceeding the temperature range defined in the user manual.
4) Make sure to evacuate properly to prevent lightning or vapor.
5) Avoid a location with direct sunlight.
6) When installing it in the panel or wall using an assembly hole, make sure to use M5 nuts and
bolts, and in case of using mounting tools, make sure to firmly install it.
7) During installation, if there is a temperature difference between the locations of the sensor and
the capillary tube, it is not possible to measure the temperature accurately, therefore, make sure
to protect the capillary tube.
8) Fix screws (bolts and nuts) by using the designated torque and tools.
