Operating Instructions Temperature Indicating Controller CF1H
***** Note to users *****
Before operating this controller, make sure you have understood the following.
Warning
Turn the power supply to the instrument OFF before wiring or
checking. Working or touching the terminal with the power switched
ON may result in Electric Shock, which can cause severe injury
or death.
Moreover, the instrument must be grounded before the power supply
to the instrument is turned on.
Caution
Do 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: °C
and 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”.

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 time referring 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 circuit 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
/
key is pressed, it starts the program control from the step 1.
OFF
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 FAST key is pressed.
To end the program cont r ol during th e p ro ce ss .
The program control is ended if the
OUT
/
key is pressed for approx. 1 second or longer.
OFF
To change the displays.
In the PV/SV display, if the MODE key is pressed for approximately 3 seconds, the Output manipulating
value display mode is activated, and if the MODE key 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 the
program continuously.
The PV display blinks until the step at which the power failure occurs is finished.

8. Control actions
8.1 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 change
in 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 Auto-tuning PID action cannot work.
] or [] is designated, Fuzzy self-tuning
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.

(1) Burnout alarm
(Upscale)
When the thermocouple or RTD is burnt out or the input value exceeds
[Rated scale maximum value +1 % of rated scale span], the control output
is turned OFF(main output low limit value for the current output type)
and the PV display blinks [
With the input RTD Pt100 (°F), if the input value is greater than 999.9, the
PV display blinks [

For DC input, if the input value exceeds [scaling high limit value +10 % of
scaling span], the control output is turned OFF (main output low limit value
for the current output type) and the PV display blinks [].
However, if the input value exceeds 9999, the PV display blinks [
(Downscale)
When the input value falls to [Rated scale minimum value –1 % of rated scale span]
or less, the control output is turned OFF (main output low limit value
for the current output type), and the PV display blinks [
For the Thermocouple T or RTD input, if the input falls to less than –199.9,
the PV display blinks [
minimum value –1 % of rated scale span].
For DC input, if the input value falls to less than [Rated scale minimum
value –1 % of rated scale span], the control output is turned OFF (main output
low limit value for the current output type), and the PV display blinks [].
(2) Self-diagno sti c fu n ction
The CPU is monitored by a watchdog timer, and when any abnormal status is
found on the CPU, the controller is switched to warm-up status.
(3)Automatic cold junction temperature compensation (
This detects the temperature at the connecting terminal between thermocouple
and the instrument, and always keeps it on the same status at which the
reference junction is located at 0°C [32°F].
(4) Warm-up indication
For approximately 2s after the power supply to the instrument is turned on,
the type of input and the unit are indicated on the PV display, and the
maximum input rated value (for DC input, scaling high limit value) on the SV display.
(5) Setting value ramp function
When the main setting value is adjusted, it approaches the new setting value
by the set rate of change.
When the power is turned on, the control starts from the PV (process variable)
