For A2 output, terminals 12 and 13 are used.

A1 and A2 indicators light up when between the output terminals is ON, and goes out when between them

is OFF.

7.6 SV1/SV2 external selection action

If the serial communication is applied, this function is disabled.

8. Control action explanations

8.1 PID

(1) Proportional band (P)

Proportional action is the action which the control output varies in proportion to the deviation between

the setting value and the 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 setting value 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

setting point is accelerated. However, the cycle of oscillation is also accelerated and the control be-
comes 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 made

longer, an excessive returning phenomenon may occur and the control system may be oscillated.
