■Safety Precautions
Note
1. A SELV circuit is one separated from the power supply with double insulation
or reinforced insulation, that does not exceed 30 V r.m.s. and 42.4 V peak or
60 VDC.
2. A class 2 power supply is one tested and certified by UL as having the current
and voltage of the secondary output restricted to specific levels.
CAUTION
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.
CAUTION - Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process Control
Equipment. 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. (See note 1.)
d) Caution: To reduce the risk of fire or electric shock, do not
interconnect the outputs of different Class 2 circuits. (See note
2.)
Do not touch the terminals while power is being supplied. Doing
so may occasionally result in minor injury due to electric shock.
Be sure to turn OFF the power supply before mounting the option
unit. Not doing so may occasionally result in minor or moderate
injury due to electric shock.
Do not allow pieces of metal, wire clippings, or fine metallic
shavings 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.

x
CAUTION
Loose screws may occasionally result in fire.
Tighten terminal screws to the specified torque of 0.74 to
0.90 N⋅m.
Unexpected operation may result in equipment damage or
accidents if the settings are not appropriate for the controlled
system. Set the Temperature Controller as follows:
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.
Be sure that the platinum resistance thermometer type and the
input type set on the Temperature Controller are the same.

xi
Be sure to observe the following precautions to ensure the safe use of the product.
1. Do not use the product in any of the following environments.
• 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
• Places directly subject to heat radiated from heating equipment.
2. To reduce the risk of fire or electric shock, install the Temperature Control-
ler in a controlled environment relatively free of contaminants.
3. Use and store the product within the rated temperature and humidity rang-
es. Group-mounting two or more Temperature Controllers, or mounting
Temperature Controllers above each other may cause heat to build up in-
side 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 Temperature Controllers.
4. To allow heat to escape, do not block the area around the product. Do not
block the ventilation holes on the product.
5. Use the specified size (M3.5, width of 7.2 mm or less) crimped terminals
for wiring.
6. To connect bare wires to the terminal block, use copper braided or solid
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
of the same size and type, or two crimp terminals can be inserted into a
single terminal.
7. Be sure to wire properly with correct polarity of terminals. Do not wire any
of the I/O terminals incorrectly.
8. Do not wire the terminals that are not used.
9. The voltage output (control output) is not electrically isolated from the in-
ternal circuits. When using a grounded temperature sensor, do not connect
any of the control output terminals to ground.Otherwise unwanted current
paths will cause measurement errors.
10. To avoid inductive noise, keep the wiring for the Temperature Controller's
terminal block away from power cables carrying high voltages or large cur-
rents. Also, do not wire power lines together with or parallel to Temperature
Controller wiring. Using shielded cables and using separate conduits or
ducts is recommended. Attach a surge suppressor or noise filter to periph-
eral devices that generate noise (in particular, motors, transformers, sole-
noids, 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 Tem-
perature Controller and devices that generate powerful high frequencies
(high-frequency welders, high-frequency sewing machines, etc.) or surge.
11. Use the product within the rated load and power supply.
Precautions for Safe Use

xii
12. Use a switch, relay, or other contact so that the power supply voltage
reaches the rated voltage within 2 seconds. If the applied voltage is in-
creased gradually, the power supply may not be reset or malfunctions may
occur.
13. When using PID operation (self-tuning), turn ON the power supply to the
load (e.g., heater) at the same time or before turning the power supply to
the Temperature Controller ON. If power is turned ON for the Temperature
Controller before turning ON power supply to the load, self-tuning will not
be performed properly and optimum control will not be achieved.
14. Design the system (e.g., control panel) to allow for the 2 seconds of delay
required for the Temperature Controller's output to stabilize after the power
is turned ON.
15. 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.
16. Approximately 30 minutes is required for the correct temperature to be dis-
played after turning the power supply to the Temperature Controller ON.
Turn the power supply ON at least 30 minutes prior to starting control op-
erations.
17. The output may turn OFF when shifting to certain levels. Take this into con-
sideration when performing control.
18. When turning OFF the power, use a switch or relay to ensure the voltage
decreases immediately. Incorrect operation and data storage errors may
occur if the voltage decreases slowly.
19. When extending the thermocouple lead wires, always use compensating
conductors suitable for the type of thermocouple. Do not extend the lead
wires on a platinum resistance thermometer. Use only low-resistance wire
(5 Ωmax. per line) for lead wires and make sure that the resistance is the
same for all three wires.
20. Make sure that any option units are installed correctly. Do not remove the
internal PCB when installing an option unit.
21. When drawing out the Temperature Controller from the case, do not apply
force that would deform or alter the Temperature Controller.
22. When drawing out the Temperature Controller from the case to replace the
Temperature Controller, check the status of the terminals. If corroded ter-
minals are used, contact faults with the terminals may cause the tempera-
ture inside the Temperature Controller to increase, possibly resulting in fire.
If the terminals are corroded, replace the rear case as well.
23. When inserting the Temperature Controller into the case, do not force it
into the case. Doing so will damage internal parts.
24. When drawing out the Temperature Controller from the case, turn the pow-
er supply OFF first, and absolutely do not touch the terminals or electronic
components or apply shock to them. When inserting the Temperature Con-
troller, do not allow the electronic components to come into contact with the
case.
25. Static electricity may damage internal components. Always touch ground-
ed metal to discharge any static electricity before handling the Tempera-
ture Controller. When drawing out the Temperature Controller from the
case, do not touch the electronic components or patterns on the board with

xiii
your hand. Hold the Temperature Controller by the edge of the front panel
when handling it.
26. The EEPROM has a limited write life. When overwriting data frequently,
e.g., via communications, use RAM Mode.
27. Do not use paint thinner or similar chemical to clean with. Use standard
grade alcohol.
28. Use tools when separating parts for disposal. Contact with the sharp inter-
nal parts may cause injury.

xiv
Service Life
1. Use the product within the following temperature and humidity ranges:
Temperature: −10 to 55°C (with no icing or condensation)
Humidity: 25% to 85%
If the product is installed inside a control board, the ambient temperature
must be kept to under 55°C, including the temperature around the product.
2. The service life of electronic devices like Temperature Controllers is deter-
mined not only by the number of times the relay is switched but also by the
service life of internal electronic components. Component service life is af-
fected 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.
3. 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 ser-
vice 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 termi-
nals sections alone to avoid measurement errors.
Measurement Accuracy
1. When extending or connecting the thermocouple lead wire, be sure to use
compensating wires that match the thermocouple types.
2. 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.
3. Mount the product so that it is horizontally level.
4. If the measurement accuracy is low, check to see if input shift has been set
correctly.
Operating Precautions
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 in a sequence circuit.
2. When using 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 pow-
er for the load, self-tuning will not be performed properly and optimum con-
trol will not be achieved.
3. 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
installation. These devices can cause radio disturbances which adversely
affect the performance of the Controller.
