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.
