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 without 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 as well as the control panel must
not exceed 50 (122 ) if mounted through the control panel. Otherwise the life ofelectronic components (especially electrolytic capacitors) may be shortened.
Note: Avoid setting this instrument directly on or near flammable material even though
the case of this instrument is made of flame-resistant resin.

2. Wiring precautions

Caution• Do not leave bits of wire in the instrument, because they could cause fire or
malfunction.
• Use the solderless terminal with an insulation sleeve in which an M3 screw fits whenwiring the FCD-15A, FCR-15A.
• The terminal block of this instrument is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened withthe terminal screw.
• Tighten the terminal screw within 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 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. Running and maintenance precautions

Caution• It is recommended that PID auto-tuning be performed on the trial run.
• Do not touch live terminals. This may cause electric shock or operation problems.
• Turn the power supply OFF before retightening the terminal or cleaning.
Working or touching the terminal with the power switched ON may result in severe
injury or death due to Electric Shock.
• Use a soft, dry cloth when cleaning the instrument.

Do not confuse the top and bottom of the internal assembly.
If inserting the assembly into the case forcibly in the wrong direction, the PCB
may be damaged.

20Note before operating keys
• Pressing the
key for approx. 1 second from any mode turns the control output OFF.
• Once the control output OFF function is enabled, the function cannot be released
even if the power to the instrument is turned OFF and ON again.
To cancel the function, press the
key again for approx. 1 second.
• Pressing the
key registers the set value and proceeds to the next setting item.
If thekey is pressed for approx. 3 seconds from any mode, the unit reverts to the
PV/SV display mode.
Turn the Power ON
The PV display indicates the input type, and the SV display indicates input range highlimit value selected during Input type selection for approx. 2 seconds after the power isturned on. See (Table 6.1-1) below.
During this time, all outputs and LED indicators are in OFF status.
Control will then start indicating the PV (process variable) on the PV display and SV(desired value) on the SV display.

[About Lock 3]
When using the unit as a Fixed value controller
The set values of the selected Set value memory number can be changed
temporarily. However, if the memory number is changed, the changed valuesof the previous number are cancelled. (Returns to the values before setting.)
When using the unit as a Program controller
The set values of the currently performing step number can temporarily bechanged. However, if the step number is changed, the changed set values arecancelled. (Returns to the values before setting.)
Set value change during running standby status will be invalidated.
(Running starts at the values memorized in the memory.)• Be sure to select Lock 3 when changing the set value frequently via
communication function considering the life of non-volatile memory.
• Selection item:(Unlock): All set values can be changed.
(Lock 1): None of the set values can be changed.
(Lock 2): Only SV can be changed.
(Lock 3): All set values can be changed temporarily. However, changed
values revert to their previous value after the power is turned off because
they are not saved in the non-volatile memory.
This function is suitable when changing value temporarily.
Since this function has no relation to the memory life, it is well suited whenchanging set values frequently using Shinko programmable controller(PC-900, PCD-33A with SVTC option).
Do not change any setting item in Auxiliary function setting mode 2. If any
item in the mode is changed, it will affect other setting items such as the
SV and Alarm value.

• Setting range: –100.0 to 100.0 ( )• Default: 0.0
Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set atthe exact location where control is desired, the sensor measured temperature
may deviate from the temperature in the controlled location.
When controlling with plural controllers, sometimes the measured temperatures(input value) do not concur due to differences in sensor accuracy or dispersion ofload capacities. In such a case, the control can be set at the desired temperatureby adjusting the input value of sensors.
However, it is effective within the input rated range regardless of the sensor
correction value.

10. Control actions
10.1 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 production process arechanged due to things like variation and variability.
If Lock 1 or Lock 2 is selected, Fuzzy self-tuning or Auto-tuning does not work.
In the control system in which load fluctuation periodically occurs, the Fuzzy
self-tuning may malfunction.
In such cases, use the controller with the PID auto-tuning 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 theprocess, the controller checks the converging status, and performs a fineadjustment 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 afine adjustment 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, auto-tuning starts automatically.
When the auto-tuning “Perform” is selected by the keypad, auto-tuning initiates.
When the control is stabilized, the auto-tuning is released and the controller
returns to self-tuning status.
The controller can be used without Fuzzy self-tuning by selecting the internal switch.
When using the controller without Fuzzy self-tuning, perform the PID auto-tuning or
set the proper PID values by key operation.

43

10.2 Explanations of PID(1) Proportional band (P)Proportional action is the action which the control output varies in proportion to thedeviation between the SV (desired value) and the PV (process variable).
If the proportional band is narrowed, even if the output changes by a slight variationof the PV (process variable), 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 PV (process variable), control action changes to ON/OFF
action and the so-called hunting phenomenon occurs.
Therefore, when the PV (process variable) comes to the balanced position near
the SV and a constant temperature is maintained, the most suitable value isselected 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 accelerated. However, the cycle of oscillationis also accelerated and the control becomes unstable.
(3) Derivative time (D)Derivative action is used to restore the change in the PV (process variable) according
to the rate of change. It reduces the amplitude of overshoot and undershoot width.
If derivative time is shortened, restoring value becomes small, and if derivative time isextended, an excessive returning phenomenon may occur and the control system may
oscillate.

4410.3 PID auto-tuning of this controller
In order to set each value of P, I, D and ARW automatically, the auto-tuning process
should be made to fluctuate to obtain an optimal value.
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performedat or near room temperature. Therefore auto-tuning might not finish normally.
(A) In the case of large difference between the SV and PV (process variable)
as the temperature is rising.
The AT process will fluctuate at a temperature of 1.5% input span lower than the SV.

If the input value drops below -199.9, the PV display flashes “”. However,the control will perform to [Scaling low limit value -1% of scaling span].
(2) Self-diagnosis
The CPU is monitored by a watchdog timer, and when an abnormal status is found on
the CPU, the controller is switched to warm-up status.
(3) Automatic cold junction temperature compensation (Thermocouple input type)This detects the temperature at the connecting terminal between thermocouple andthe instrument, and always keeps it at the same status as if the reference junction
is located at 0 (32 ).
(4) Warm-up indication
For approximately 2 seconds after the power supply to the instrument is turned on, theinput type and the temperature unit are indicated on the PV display, and the input range
high limit value (for DC input, scaling high limit value) on the SV display.
(5) SV (desired value) ramp function
When the SV is adjusted, it approaches the new SV by the preset rate of change.
When the power is turned on, the control starts from the PV (process variable)
and approaches the SV by the rate of change.
