Safety Precautions
WARNING
Do not use this device in an environment with conductive pollution, or with dry non-
conductive pollution which can become conductive due to condensation, etc.
Otherwise, problems such as tracking phenomena may damage parts, resulting in fire.
When wiring the power for this device, be sure to mount a shutoff switch for the main power
to this unit within reach of the operator.
In addition, when wiring the power for AC power models, install a time-lag (T) fuse (rated
current 0.2 A, rated voltage 250 V) as specified by IEC 127.
Otherwise, tracking phenomena or parts failure due to other factors may cause fire.
Do not disassemble this device.
Doing so might cause electric shock or faulty operation.
Before removing, mounting, or wiring this device, be sure to turn off the power to the device
and all connected devices. Failure to do so might cause electric shock.
Do not touch electrically charged parts such as the power terminals.
Doing so might cause electric shock.
CAUTION
Use this device within the operating ranges recommended in the specifications (temperature,
humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.).
Do not block ventilation holes.
Doing so might cause fire or faulty operation.
Wire this device properly according to predetermined standards.
Also wire the device using specified power leads according to recognized installation
methods. Failure to do so might cause electric shock, fire or faulty operation.
Do not allow lead clippings, metal shavings or water to enter the controller case.
Doing so might cause fire or faulty operation.
Firmly tighten the terminal screws at the torque listed in the specifications.
Insufficient tightening of terminal screws might cause electric shock or fire.
Do not use unused terminals on this device as relay terminals.
Doing so might cause electric shock, fire, or faulty operation.
We recommend attaching the terminal cover (sold separately) after wiring this device.
Failure to do so might cause electric shock, fire, or faulty operation.
Use the relays within the recommended life.
Failure to do so might cause fire or faulty operation.
If there is a risk of a power surge caused by lightning, use a surge absorber (surge protector)
to prevent fire or device failure.
Do not make incorrect connections. If the cables are connected incorrectly, this might cause
the unit to malfunction.
The controller does not function for approximately 6 s. after the power has been turned
ON. Great care should be taken if the relayoutput from the controller is used as an interlock
signal.

v
CAUTION
There is no isolation between control outputs 1 and 2. When necessary, use an appropriate
isolator.
Do not connect multiple loader cables to multiple units from one personal computer. The
current coming from other circuits might cause an error in the indication of the PV.
When wiring RS-485 communications, do not connect a terminating resistor to either end of
the communication path. A terminating resistor might cause a communication failure.
Do not operate the keys with a mechanical pencil or other sharp-tipped object.
Doing so might cause faulty operation.
In addition to ON/OFF control and conventional PID control, this unit is equipped with self-
tuning control, which does not require manual setting of control constants. Self-tuning
control ensures stable control even after a change in the SP or an external disturbance. This
is achieved by monitoring the control target, learning its characteristics, and automatically
calculating control constants.
Before Using This Unit
The protective film is adhered to the front console of this unit to protect the surface.
After the installation and wiring work has been completed, stick a scotch tape to the corner of the console and pull it
out in the direction indicated by an arrow to peel off the protective film.
Handling Precautions
If you attempt to peel off the protective film with your fingernail, this might
cause damage to the console.
