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”.

6.2 When using the CF1H as a simplified program controller

(1) Turn the power 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 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.).

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.

Operating Instructions Temperature Indicating Controller CF1H

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.

9. Other functions

(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 [ maximum value +1 % of rated scale span]. 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) and approaches the main setting value by the rate of change.

Notices

• Use a thermocouple and compensating lead wire according to the input specifications of this controller.

• Use a 3-wire RTD system according to the input specifications of this controller.

• This controller has no built-in power switch or fuse. It is necessary to install them manually (IEC approved, 100 V AC 5 A or 220 V AC 5 A) in the circuit near the external controller.

• In the case of 24 V DC, do not confuse the polarity.

• For the relay contact output type, use an external auxiliary electromagnetic

switch to protect the built-in relay contact.

• When wiring, keep the input wire (Thermocouple, RTD, etc.) away from AC source and the load wire to avoid external interference.

• Use a thick wire (1.25 to 2.0 mm
