Warning Symbols
CAUTION
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Electric shock, fire, or malfunction may occasionally occur. Do not allow metal objects, conductors,
cuttings from installation work, or moisture to enter the Digital Controller, the Setup Tool ports, or
between the pins on the connectors on the Setup Tool cable.
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 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.
c) Signal inputs are SELV, limited energy.
d) Caution: To reduce the risk of fire or electric shock, do not interconnect the outputs of different Class 2 circuits.
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.
Loose screws may occasionally result in fire. Tighten the terminal screws to the specified torque of 0.5
N•m.
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 Digital 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 Digital
Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

Long-term overvoltage: 250 V + (Power supply voltage)
Always externally connect the recommended fuse that is specified
in the Instruction Manual before you use the Digital Controller.
Analog Input
• If you input an analog voltage or current, set the Input Type
parameter to the correct input type.
• Do not use the Digital Controller to measure a circuit with
Measurement Category II, III, or IV.
• Do not use the Digital Controller to measure an energized circuit to
which a voltage that exceeds 30 Vms or 60 VDC is applied.
The protection provided by the Digital Controller may be impaired if the
Digital Controller is used in a manner that is not specified by the
manufacturer.
This product with sokect P2CF-11(E) or P3GA-11 gets the UL Listing
Certification.It must be used with the sokect which mentioned above.
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.
Use the product within specifications.
(1) The product is designed for indoor use only. Do not use the product outdoors. Do not use or store the product
in any of the following locations.
•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/store within the rated temperature and humidity ranges. Provide forced-cooling if required.
(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 of crimped terminals (M3.5, width 7.2 mm or less) for wiring. To connect bare wires to
the terminal block, use copper braided or solid wires with a gage of AWG24 to AWG14 (equal to cross-
sectional area of 0.205 to 2.081 mm 2 ). (The stripping length is 5 to 6 mm.) Up to two wires of same size and
type, or two crimped terminals can be inserted into a single terminal.
(6) Do not wire the terminals which are not used.
(7) Allow as much space as possible between the controller and devices that generate a powerful high- frequency
or surge. Separate the high-voltage or large-current power lines from other lines, and avoid parallel or
common wiring with the power lines when you are wiring to the terminals.
(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 Digital 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 the load and the unit ON simultaneously, or turn the load ON before you turn
the controller ON.
(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) Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine, alcohol, or any
cleaners that contain these or other organic solvents. Deformation or discoloration may occur.
(14) Design system (control panel, etc) considering the 2 second of delay that the controller's output to be set after
power ON.
(15) The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when
performing control.
(16) The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data during communications or other operations.
(17) When disassembling the Temperature Controller for disposal, use suitable tools.
(18) Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion Cable is
connected. The Digital Controller may malfunction.
(19) The terminals can reach temperature of up to 65℃.

• Insert the main unit through the mounting hole in the panel (1 to 5 mm thickness). Insert the
mounting brackets (supplied) into the fixing slots located on the top and bottom of the rear
case.
• Tighten the two mounting screws on the top and bottom of the adapter to keep them
balanced, and finally tighten them to a torque of between 0.29 and 0.39 N·m.
• When more than one machine is installed, make sure that the ambient temperature does
not exceed the specified limit.
• STOP:
Lit when "Run/Stop" is stopped during operation.
During control stop, functions other than control output
are valid.

* When complying with EMC standards, the line connecting the sensor must be 30 m or less.
If the cable length exceeds 30 m, compliance with EMC standards will not be possible.
