• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• No mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )
that does not change rapidly
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current
is flowing
• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
Note: Do not install this instrument near flammable material even though the case of
this instrument is made of flame-resistant resin.
Avoid setting this instrument directly on flammable material.
2. Wiring precautions
Caution
• Use the solderless terminal with an insulation sleeve that fits in the M3 screw when
wiring the KT9 Series.
• The terminal block of this instrument is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened with
the terminal screw.
• Tighten the terminal screw within the specified torque.
If excessive force is applied to the screw when tightening, the terminal screw or
case may be damaged.
• Do not apply a commercial power source to the sensor which is connected to the
input terminal nor allow the power source to come into contact with the sensor.
• This controller does not have built-in power switch, circuit breaker or fuse.
It is necessary to install them near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
3. Running and maintenance precautions

Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at a
location where control is desired, the sensor measuring temperature may deviate from
the temperature in the controlled location. When controlling with plural controllers,
the accuracy of sensors affects the control.
Therefore, sometimes the measured temperatures (input value) do not concur. In such a
case, the control can be set at the desired temperature by adjusting the input value of
sensors.

8. Control action explanations
8.1 PID
(1) Proportional band (P)
Proportional action is the action during which the control output varies in proportion to
the deviation between the SV and the PV (processing temperature).
If the proportional band is narrowed, even if the output changes by a slight variation
of the processing temperature, better control results can be obtained as the offset
decreases.
However, if the proportional band is narrowed too much, even slight disturbances
may cause variation in the processing temperature, control action changes to
ON/OFF action and the so-called hunting phenomenon occurs.
Therefore, when the processing temperature comes to the balanced position near
the SV and a constant temperature is maintained, the most suitable value is selected
by gradually narrowing the proportional band while observing the control results.
(2) Integral time (I)
Integral action is used to eliminate offset. When the integral time is shortened, the
returning speed to the set point is accelerated. However, the cycle of oscillation is also
accelerated and the control becomes unstable.
(3) Derivative time (D)
Derivative action is used to restore the change in the processing temperature according
to the rate of change. It reduces the amplitude of overshoot and undershoot width.
If the derivative time is shortened, restoring value becomes small, and if the derivative
time is extended, an excessive returning phenomenon may occur and the control
system may oscillate.
8.2 PID auto-tuning of this controller
In order to set each value of P, I, D and ARW automatically, the auto-tuning process
should be made to fluctuate to obtain an optimal value.
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed
at or near room temperature. Therefore auto-tuning might not finish normally.
(A) In the case of a large difference between the SV and processing temperature as
the temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower
than the SV.

8.3 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indication
is stabilized within the proportional band during the PD action.
Since the corrected value is internally memorized, it is not necessary to perform
the auto-reset again as long as the process is the same.
However, when the proportional band is set to 0, the corrected value is cleared.
