1. Installation precautions
CautionThis instrument is intended to be used under the following environmental
conditions (IEC61010-1):
Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85%RH• No large capacity electromagnetic switches or cables through which large current
is flowing.
• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
• Take note that the ambient temperature of this unit must not exceed 50 (122 ) if
mounted through the face of a control panel. Otherwise the life of electronic
components (especially electrolytic capacitors) may be shortened.
Note: Avoid setting this instrument directly on or near flammable material eventhough the case of this instrument is made of flame-resistant resin.

2. Wiring precautions
Caution• Use the solderless terminal with an insulation sleeve in which the M3 screw fits
when wiring the FCR-23A.
• The terminal block of this instrument is designed to be wired from the upper side.
The lead wire must be inserted from the upper side of the terminal, and fastened withthe terminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied tothe screw when tightening, the screw or case may be damaged.
• Do not apply a commercial power source to the sensor which is connected to the
input terminal nor allow the power source to come into contact with the sensor, as the
input circuit may be burnt out.
• This controller has no built-in power switch, circuit breaker or fuse.
It is necessary to install them near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• For a 24V AC/DC power source, do not confuse polarity when using direct current(DC).

3. Operation and maintenance precautions
Caution• It is recommended that AT be performed on the trial run.
• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal andcleaning.

5.2 Wiring example

Caution• Use a thermocouple and compensating lead wire according to the sensor input
specifications of this controller.
• Use a 3-wire RTD system according to the sensor input specifications of this controller.
• This controller does not have a built-in power switch, circuit breaker or fuse. Therefore,
it is necessary to install them in a circuit near the external controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• When using a relay contact output type, externally use a relay according to the capacityof the load to protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load
wires to avoid external interference.
• Use a thick wire (1.25 to 2.0mm2) for grounding.

4310. Control actions
10.1 Fuzzy self-tuning PID
Fuzzy self-tuning PID 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 production processchange due to various external factors (types and rates of production).
If Lock 1 or Lock 2 is selected, Fuzzy self-tuning or AT does not work.
In the control system in which load fluctuation periodically occurs, the Fuzzy
self-tuning PID may malfunction. In such cases, use controllers with the AT mode.
(1) When the control initiates, the unit performs this function by the PID values previously
adjusted.
(2) When the control result is disordered by disturbance or a change in the process, thecontroller checks the convergence 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 changes the PID
values to correct this.
(d) When hunting occurs, the controller checks its waveform and performs a fineadjustment of PID values.
The instrument is always in self-tuning status, and when deviation occurs, the tuning
starts. Even in Fuzzy self-tuning status, when very large hunting occurs and thecontrol is not stabilized, AT starts automatically.
When the AT “Perform” is selected by the keypad, AT initiates. When the control isstabilized, the AT is released, and the controller returns to self-tuning status.
10.2 PID(1) Proportional band (P)Proportional action is the action during which the control output varies in proportion to
the deviation between the SV (desired value) and the PV (process variable).
If the proportional band is narrowed, the output changes by a slight variation of the processing
temperature, and 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, 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 SV (desired 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, thereturning 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 thederivative time is shortened, the restoring value becomes small, and if the derivative timeis extended, an excessive returning phenomenon may occur and the control system may
oscillate.
4410.3 AT of this controller
In order to set each value of P, I, D and ARW automatically, the AT process should bemade to fluctuate to obtain an optimal value.
Sometimes the AT process will not fluctuate if AT is performed at or near room
temperature. Therefore AT might not finish normally.
(A) In the case of a large difference between the SV (desired value) and PV (process
variable) as the temperature is rising.
The AT process will fluctuate at the temperature 1.5% of input span lower than the SV.
