Setting Unit: °C or °F

Initial Value1000●PV compensation gain setting[Function]
Multiplies PV (measurement value) of input with the correction value.
[Sample Setting]
In case PV is displayed as 90°C in an environment where the actual temperature is 100°C, PV can still be adjusted to
100°Cby setting the gain of PV correction to 1.11 (times). [Computation formula = 90°C(before PV correction) x 1.11
times = approximately 100°C]

24

[Function]
Adds correction value to PV (measurement value).
[Sample Setting]
In case PV is displayed as 90°Cin an environment where the actual temperature is 100°C, PV can still be adjusted to
100°Cby zero-setting the PV correction to 10 (°C). [Computation formula = 90°C(before PV correction) + 10°C= 100°C]※ Numerical formula for the combination of “PV compensation gain setting” and “Zero Setting of PV Correction” is thefollowing:“(Before PV Correction x PV compensation gain setting) + Zero Setting of PV Correction = After PV Correction”
Caution:1) Setting the gain of PV correction greater may cause instability of the measurement value.
2) Setting the gain of PV correction to less than x1 will change the range of display.
[Sample Setting]If the input of K thermocouple is -199.9°C–999.9°C:
PV compensation gain setting: x0.5 → “-100.0°C–500.0°C”
PV compensation gain setting: x0.1 → “-20.0°C–100.0°C”
3) Setting the zero setting of PV correction to less than 0 will change the range of display.
[Sample Setting]If the input of K thermocouple is -210°C–1382°C:
Zero setting of PV correction: +100°C → “-110°C–1382°C”
Zero setting of PV correction: -100°C → “-210°C–1282°C”

00[Function]
A function to programmatically realize CR filtering effect by performing a primary delay operation for PV of the input.
Filter effect will be set through time constant.
(Time constant is a time that was spent before PV to reach up to approximately 60% when the input has changed in a
step-by-step manner)※The purposes of PV filter are the following:① The effect of the electrical noise that was applied to the input can be minimized by eliminating the high-frequency
noise.
② The response against sudden change of the input can be delayed.

3) Please be careful that if 5 (Output 1/Output 2 Auto Tuning) is set, AT will also be performed for Output 1.
<Auto Tuning>
Auto Tuning calculates the PID constant through the response of ON/OFF.
Calculated PID constant can only be changed by redoing the auto tuning.
Therefore, it is ideal for the control of a situation where temperature changes periodically, such as seal-packaging
device.
<Self-Tuning>Self-Tuning is a method of tuning that automatically calculates the PID constant by observing the control wave.
It is ideal for the control of a situation where subject of control differs, setting value changes, or environment—such as
ambient temperature—changes.
Unlike auto tuning, self-tuning does not require tuning time.

Sets the sensitivity of the switching of ON/OFF during AT.
Switching of ON/OFF will be performed during AT.

Too much fluctuation in the measurement value during AT may affect the tuning result and may cause a miscalculation of
the PID constant.
In such a case, adjust AT Sensitivity to correct the tuning result.
Also, if AT sensitivity is small, fluctuations in the measurement value caused by the noise may occur or control may greatly
be affected by the external environment if it is operated in the temperature that is close to normal.
In such a case, the product may recognize the effect caused by the external environment as a characteristic of the subject ofcontrol, and therefore, the product may not be able to come up with the optimal control characteristic.

Proportional bandsetting for OUT1

Setting Range: 0.1–200.0
Setting Unit: % that corresponds to SLL-SLH

Initial Value

30

Sets the proportional band for Output 1.
In case of heating and cooling controls, the proportional band of the heating side will be set.
See the figure shown below on how the proportional band will be placed during the heating control. In case of cooling control,
the proportional band will be placed on top.

Proportional bandwidth can be calculated by the following formula:
Proportional Bandwidth = (SLH - SLL) x P1
SLH: Maximum Limit of SV Limiter
SLL: Minimum Limit of SV Limiter
Example: If SLH=1200°C, SLL=0°C, and P1=3.0%, then:(1200°C -0°C)×3% = 36°C
Output gradually increases from the point where the temperature gets lower than SV by 36°C.
In general, setting the proportional band wider will make the startup slow.
If the proportional band is narrow, on the other hand, the startup is faster but may cause instability of control, such as
overshooting and hunting.

Reset Operation is an action performed to make the deviation between setting values, which happens during the proportional
control, closer to zero.

Reset Time is a numerical value that sets the intensity of the reset operation. It shall be set in seconds. The shorter the time,the more intense the reset operation becomes (because it tries to reset the deviation within the time duration that was set).

In case of heating and cooling controls, both heating and cooling controls use this setting. (Setting cannot be performed
individually)
Derivative operation is an operation performed to quickly normalize the state of control against a sudden disturbance by
providing a large amount of manipulated variable.
It provides an output with the size that is proportional to the time derivative value of the measurement value.
Since proportional operation and reset operation are operations that will correct the result of control, they are not capableof responding timely to a sudden temperature change (such as a disturbance). Derivative action will be used to cover that
disadvantage.
It is a numerical value that sets the intensity of the derivative action. It shall be set in second. The longer the time, the more
intense the derivative operation becomes (because the interval to get the difference gets wider).

･ This product can switch the input type of the sensor. Upon using the product, please match the type of the sensor with thesensor setting of the product.
･ This product can perform two types of control: PID and ON/OFF.
The characteristics of each control are described below. Choose the control to use based on their characteristics.
PID Control
Pros: Can achieve better control result than ON/OFF control.
Cons: Life of a relay contact point gets shorter because of the frequent ON and OFF of the output.
ON/OFF Control
Pros: Life of a relay contact point is generally longer since it turns ON if the temperature is lower than the setting value and OFFif higher.
Cons: Less controllability than PID control.
