■Safety Precautions
*1 A SELV circuit is one separated from the power supply with double insulation or reinforced insulation,
thatdoes not exceed 30 V r.m.s. and 42.4 V peak or 60VDC.
*2 A class 2 power supply is one tested and certified by UL as having the current and voltage of thesecondary
output restricted to specific levels.
CAUTION
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to electric
shock.
Do not allow pieces of metal, wire clippings, or fine metallic
shav-ings or filings from installation to enter the product. Doing
so may occasionally result in electric shock, fire, or
malfunction.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from explosion may
occasionally occur.
Never disassemble, modify, or repair the product or touch any
of the internal parts. Minor electric shock, fire, or malfunction
may occasionally occur.
CAUTION - Risk of Fire and Electric Shock
a)This product is UL listed as Open Type Process Control
Equip-ment. It must be mounted in an enclosure that does
not allow fire to escape externally.
b)More than one disconnect switch may be required to de-
energize the equipment before servicing the product.
c)Signal inputs are SELV, limited energy.*1
d)Caution: To reduce the risk of fire or electric shock, do not
inter-connect the outputs of different Class 2circuits.*2
If the output relays are used past their life expectancy, contact
fusing or burning may occasionally occur.Always consider the
application conditions and use the output relays within their
rated load and electrical life expectancy. The life expectancy of
output relays varies considerably with the output load and
switching conditions.

VI
CAUTION
Tighten the terminal screws to between 0.74 and 0.90 N·m.
Loose screws may occasionally result in fire. (See note.)
Set the parameters of the product so that they are suitable for
the system being controlled. If they are not suitable,
unexpected operation may occasionally result in property
damage or accidents.
A malfunction in the Temperature Controller may occasionally
make control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the event
of malfunction of the Temperature Controller, take appropriate
safety measures, such as installing a monitoring device on a
separate line.
A semiconductor is used in the output section of long-life
relays. If excessive noise or surge is impressed on the output
terminals, a short-circuit failure is likely to occur. If the output
remains shorted, fire will occur due to overheating of the
heater or other cause. Take measures in the overall system to
prevent excessive temper-ature increase and to prevent fire
from spreading.

VII
Precautions for Safe Use
Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects onthe
performance and functions of the product. Not doing so may occasionally result in unexpected events.
(1) The product is designed for indoor use only. Do not use the product outdoors or in any of the
followinglocations.
•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 Controller within the rated ambient temperature and humidity.
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. Insuch 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 onthe
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-wiredconnection,
use stranded or solid copper wires with a gage of AWG24 to AWG14 (equal to a cross-sectional area of
0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two wires or two crimpterminals 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 and using separate 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 two seconds of turning ON the power 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 Temperature Controller. 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 marked 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.

VIII
(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 second 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.
●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 temperature must be kept to under
55°C, including the temperature around the Controller.
The service life of electronic devices like Temperature Controllers is determined not only by the num-
ber of times the relay is switched but also by the service life of internal electronic components.
Component 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.
●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 peripheral devices that generate noise (in particular,
motors, transformers, solenoids, magnetic coils or other equipment that have an inductance compo-
nent). 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 gener-
ate powerful high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or
surge.
●Ensuring Measurement Accuracy
When extending or connecting the thermocouple lead wire, be sure to use compensating wires
thatmatch the thermocouple types.
When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use
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.
●Waterproofing
The degree of protection is as shown below. Sections without any specification on their degree of
protection or those with IP䡺0 are not waterproof.
Front panel: NEMA4X for indoor use (equivalent to IP66)
Rear case: IP20, Terminal section: IP00

IX
Precautions for Operation
(1) It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON.
Due 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 Temperature Controller before
turning ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved. When starting operation after the Temperature Controller has warmed up, turn OFF the power
and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the
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, television set, or wireless installing. The Controller
maycause radio disturbance for these devices.
