***** Note to users *****

Before operating this controller, make sure you have understood the following.

WarningTurn the power supply to the instrument OFF before wiring or

checking. Working or touching the terminal with the power switched

ON may result in Electr ic Shock, which can cause severe injury

or death.

Moreover, the instrument must be grounded before the power supply

to the instrument is turned on.

CautionDo not apply a commercial power source to the sensor connecting to the input terminal

nor allow the power source to come into contact with the sensor, as the input circuit

may be burnt out.

Set-up by the DIP switch and the rotary switch inside of the controller is required

before the power is turned on.

The product is factory adjusted as [Sensor input: K, Control action: Fuzzy self-tuning

PID, Heating action, Alarm (A1): No alarm action, no standby function, Unit: Cand Program starting form: manual]. Refer to page 9 Setup.

It is recommended that the PID auto-tuning be performed on the trial run.

It is advised to provide the protective device against such environmental conditions

which may cause damage to the device or contribute to the deterioration of its parts.

If you are mounting this controller to the control panel or machine, read this manual from

Chapter 10 Mounting to control panel or 11 Wiring connection after checking the model

name by 1 Model names.

If you are operating this controller already mounted, read this manual from Chapter 2 Name

and functions of the sections or 4 Operations.

When the Setting value memory number is selected by external operation,

the number cannot be selected by front key operation.

When selecting the memory number by front key operation, all terminals

(b0, b1, b2and COM) should be open.

Memory number cannot be changed during setting mode or PID auto-tuning.

Setting value memory funct ion operating procedure(1) In the PV/SV display mode, select the setting value memory number by

connecting the terminals.

(2) In the setting mode, set each setting value; Main setting, PID each value,

Cooling control proportional band value, Alarm setting values (A1 and A2),

Overlap band/Dead band value, Main output high limit, Main output low

limit, Cooling output high limit, Cooling output low limit.

(3) After setting, press the MODEkey to revert to the PV/SV display mode.

RegistrationThe setting data is registered to the file whose number is indicatedon the Setting value memory number display.

When the number is called up, the selected number by terminal connectionis displayed, and the control is performed by the data (setting value) of the file.

To change the setting values, repeat the operation above-mentioned, and

the values will be changed to new values.

6 RunningAfter the controller has been mounted to the control panel and wiring is

completed, it can be started in the following manner.

6.1 When using the CF1H as a Temperature cont rol ler

(1) Turn the power suppl y to the CF1H ON.

For approx. 2s after the power is switched ON, the type of sensor and the unit

designated in Sensor input designation (page 10, 11) will be indicated on the

PV display, and the rated maximum value will be indicated on the SV display.

See [table 6.1-1].

During this time, all outputs and LED indicators are in their OFF status.

After that, the display turns to the PV/SV display.

When the Control output OFF function is working, the item selected in

Display selection when control output is off is displayed on the PV display.

6.2 When using the CF1H as a simp lified p rogram control ler

(1) Turn the pow er supply to the CF1H on.

For approx. 2s after the power is turned ON, the type of sensor and the unit designated in Sensor input

designation (page 12, 13) are indicated on the PV display, and the rated maximum value is indicated on

the SV display.

See [table 6.1-1].

During this time, all outputs and LED indicators are in their OFF status.

After that, the display reverts to the PV/SV display.

When the Control output OFF function is working, the item selected in Display selection when control

output is off is displayed on the PV display. (See page 32.)

(2) Input each setting value and each step timereferring to Chapter 4. Operations

(page 13ff), especially page 17 (Setting value memory) and page 35 (Program control

change, Step time setting). Then the PV display will indicate the actual temperature

and the status turns standby.(3) Turn the load ci rcu it power ON.

(4) Program control start

If Automatic start is designated in the Program start Auto/Manual designation (page 10), it will switch to

warm-up status for approx. 2 seconds after the power is turned on, and then will automatically start the

program control from step 1.

If Manual start is designated in Program start Auto/Manual designation (page 10), it will switch to

warm-up status for approx. 2 seconds after the power is turned on, and then it reverts to standby status.

In this status, if the OUT/OFFkey is pressed, it starts the program control from the step 1.

While the program control is being performed, the change of Step number (by Setting value memory

number) is ineffective.

To make the step time progress faster.

The step time progress becomes 60 times as fast as usual when the FASTkey is pressed.

To end the program cont rol during the process.

The program control is ended if the OUT/OFFkey is pressed for approx. 1 second or longer.

To change the displays.

In the PV/SV display, if the MODEkey is pressed for approximately 3 seconds, the Output manipulating

value display mode is activated, and if the MODEkey is pressed again, the Step rest time display will be

indicated (see page 38.).

Instrument status when power failure is restored.

When power is restored after a power failure occurs during program control, the CF1H performs theprogram continuously.

The PV display blinks until the step at which the power failure occurs is finished.

8. Control actions8.1 Fuzzy self-tuning

Fuzzy self-tuning is a function to perform a fine adjustment of PID values automatically. The stable

control can be carried out even if the conditions of the process are changed due to things like changein types and rates of production.

(1) When the control is rising, the controller performs the control by the PID

values tuned in advance.

(2) When the control result is disordered by the disturbance or a change in the process, the controller

checks the converging status, and performs a fine adjustment of PID values if necessary.

(a) If the convergence is performed smoothly, the PID values are not changed.

(b) If the convergent speed is slow, the controller corrects the PID values

to accelerate the convergence.

(c) When overshoot is generated during the convergence, the controller corrects

the PID values so as not to generate the overshoot.

(d) When hunting is generated, the controller checks the waveform and performs

a fine adjustment of PID values.

(3) The controller can be used without Fuzzy self-tuning by designating the internal switch.

(4) When using the controller for the first time, performing the PID auto-tuning

or setting the proper PID values by key operation is recommended.

The instrument is always in self-tuning status itself, and when deviation is created, it starts the tuning.

Even if in Fuzzy self-tuning status, when very large hunting is caused and the control is not stabilized,

it starts auto-tuning automatically.

When the auto-tuning performance is designated by the key operation, tuning is initiated, and when the

control is stabilized, the auto-tuning is released and returns to self-tuning status.

When lock mode [ ] or [ ] is designated, Fuzzy self-tuning

or Auto-tuning PID action cannot work.

With the control system in which load fluctuation periodically occurs,

the Fuzzy self-tuning may fall into malfunction.

In such a case, use the controller with the PID auto-tuning mode.

8.2 Explanations of 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 when the proportional band is narrowed too much, even slight disturbances may cause

variation in the processing temperature, and 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 quickened. However, the cycle of oscillation is also quickened 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 made

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

8.3 PID auto-tuning o f this controllerIn order to decide each value of P, I, D and ARW automatically, this systemgives the fluctuation to the controlling object by force.

(1) When the difference between setting value and proc essing temperature

is l arge when the temperature rises.Fluctuation is given at the temperature 1.5 % of scaling span less than the setting value.

(2) When the control is stable or when control temperature is w ithin 1.5 %of scaling span.Fluctuation is given at the setting value.

(3) When the contro l temperature is 1.5 % or greater of scaling span higherthan the setting value.

Fluctuation is given at the temperature 1.5 % of scaling span higher than the setting value.
