Precautions for Safe Use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on
the performance and functions of the product. Not doing so may occasionally result in unexpected events.
1) The product is specifically designed for indoor use only. Do not use the product outdoors or in any of the
following places.
• Places directly subject to heat radiated from heating equipment.
• Places subject to splashing liquid or oil atmosphere.
• Places subject to direct sunlight.
• Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
• Places subject to intense temperature change.
• Places subject to icing and condensation.
• Places subject to vibration and large shocks.
2) Use and store the Digital Temperature Controlle r within the ra te d am b ien t tem p er a tu re and hum id i ty.
Gang-mounting two or more temperature controllers, or mounting temperature controllers above each
other may cause heat to build up inside the temperature controllers, which will shorten their service life. In
such a case, use forced cooling by fans or other means of air ventilation to cool down the Digital
Temperature Controllers.
3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes on
the product.
4) Be sure to wire properly with correct polarity of terminals.
5) Use the specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. For open-wired
connection, use stranded or solid copper wires with a gage of AWG24 to AWG14 (equ al to a crosssectional area of 0.205 to 2.081 mm
size and type or two crimp terminals can be inserted into a single terminal.
6) Do not wire the terminals which are not used.
7) To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block away from
power cables carry high voltages or large currents. Also, do not wire power lines together with or parallel
to Digital Temperature Controller wiring. Using shielded cables an d using separat e conduits or ducts is
recommended.
Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular, motors,
transformers, solenoids, magnetic coils or other equipment that have an inductance component).
When a noise filter is used at the power supply, first check the voltage or current, and attach the noise
filter as close as possible to the temperature controller.
Allow as much space as possible between the Digital Temperature Controller and devices that generate
powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
8) Use this product within the rated load and power supply.
9) Make sure that the rated voltage is attained within 2 seconds of turning ON the po we r b y using a switch or
relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may
occur.
10) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the
power before starting actual control operations to ensure the correct temperature display.
11) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital T emperat ure Co ntroller. If power is turned ON for the Digital Temperature
Controller before turning ON power for the load, self-tuning will not be performed properly and optimum
control will not be achieved.
12) A switch or circuit breaker should be provided close to this unit. The switch or circuit breaker should be
within easy reach of the operator, and must be m arked as a disconnecting means for this unit.
13) Always turn OFF the power supply before pulling out the interior of the product, and never touch nor apply
shock to the terminals or electronic components. When inserting the interior of the product, do not allow
the electronic components to touch the case.

14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
15) Design system (control panel, etc) considering the 2 seconds of delay that the controller’s output to be set
after power ON.
16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
17) The number of EEPROM write operations is limited. Therefore, use RAM write mode when frequently
overwriting data during communications or other operations.
18) Always touch a grounded piece of metal before touching the Digital Temperature Controller to discharge
static electricity from your body.
19) Control output that is voltage output is not isolated from the internal circuits.When using a grounded
thermocouple,do not connect any of the control output terminals to ground. (Doing so may result in an
unwanted circuit path, causing error in the measured temperature.)
20) When replacing the body of the Digital Temperature Controller, check the condition of the terminals. If
corroded terminals are used, contact failure in the terminals may cause the temperature inside the Digital
Temperature Controller to increase, possibly resulting in fire. If the terminals are corroded, replace the
case as well.
21) Use suitable tools when taking t he Dig ita l T em p erature Controller apart for dispos a l. Sh ar p pa rt s ins ide th e
Digital Temperature Controller may cause injury.
22) Check the orientation of the connectors on the Conversion Cable before connecting the Conversion Cable.
Do not force a connector if it does not connect smoothly. Using excessive force m ay damage the
connector.
23) Do not place heavy object on the Conversion Cable, bend the cable past its natural bending radius, or pull
on the cable with undue force.
24) Do not connect or disconnect the Conversion Cable while communications are in progress. Product faults
or malfunction may occur.
25) Make sure that the Conversion Cable
26) Do not touch the connectors on the Conversion Cable with wet hands. Electrical shock may result.

s metal components are not touching the external power terminals.
O Service Life
Use the Temperature Controller within the following temperature and humidity ranges:
Temperature: −10 to 55°C (with no icing or condensation), Humidity: 25% to 85%
If the Controller is installed inside a control board, the ambient tem perature must be kept to under 55°C,
including the temperature around the Controller.
The service life of electronic devices like Temperature Con trolle rs is dete rm ined not only b y the nu mbe r
of times the relay is switch ed but also by the s ervice lif e of interna l electro nic c omponen ts. Com pone nt
service life is affected by the ambient temperature: the higher the temperature, the shorter the service
life and, the lower the temperature, the longer the service life. Therefore, the service life can be
extended by lowering the temperature of the Temperature Controller.
When two or more Temperature Controllers are mounted horizontally close to each other or vertically
next to one another, the internal temperature will increase due to heat radiated by the Temperature
Controllers and the service life will decrease. In such a case, use forced cooling by fans or other means
of air ventilation to cool down the Temperature Controllers. When providing forced cooling, however, be
careful not to cool down the terminals sections alone to avoid measurement errors.
O Ambient Noise
To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block wiring
away from power cables carrying high voltages or large currents. Also, do not wire power lines together
with or parallel to Digital Temperature Controller wiring. Using shielded cables and using separate conduits or ducts is recommended.
Attach a surge suppressor or noise filter to per ipher al d evices th at ge nerate noise (in particular, motors,
transformers, solenoids, magnetic coils or other equipment that have an inductance component). When
a noise filter is used at the power supply, first check the voltage or current, and attach the noise filter as
close as possible to the Temperature Controller.
Allow as much space as possible between the Digital Temperature Controller a nd devices that ge nerate
powerful high frequencies (high-freq u ency we lde rs , high-frequency sewing machines, etc.) or surge.
xii
O Ensuring Measurement Accuracy
When extending or connecting the thermocouple lead wire, be sure to use compensating wires that
match the thermocouple types.
When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use
wires that have low resistance and keep the resistance of the three lead wires the same.
Mount the Temperature Controller so that it is horizontally level.
If the measurement accuracy is low, check to see if input shift has been set correctly.
O Waterproofing
The degree of protection is as shown below. Sections without any specification on their degree of protection or those with IP@0 are not waterproof.

Precautions for Operation
1) It takes approximately 2 seconds for the outputs to turn ON from after the power supply is tu rn ed ON. Du e
consideration must be given to this time when incorporating Temperature Controllers into a control panel
or similar device.
2) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the
power before starting actual control operations to ensure the correct temperature display.
3) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Temperature Controller. If power is turned ON for the Te mperature Controller
before turning ON power for the load, self-tuning will not be performed properly and op timum control will
not be achieved. When starting operation after the Temperature Controller has warmed up, tu rn OFF the
power and then turn it ON again at the same time as tu rn ing ON power for the loa d. (In ste ad of turnin g th e
Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)
4) Avoid using the Controller in places near a radio, tele vision set, or wireless ins talling. The Controller may
cause radio disturbance for these devices.

the input temperature setting range is –20.0 to +500.0°C, 1 EU is 0.1°C.
For analog inputs, the size of EU varies according to the decimal point position o f the scaling settin g,
and 1 EU becomes the minimum scaling unit.
