Setup (setting the Input type, Event output allocation, SV, etc.) should be done before using thiscontroller, according to the user’s conditions.
Perform setup in Initial setting mode.
Setting items in Initial setting mode are shown in (Table 6.1).
If the user’s specification is the same as the factory default value of this instrument, or if user’s
instrument has already been installed in a system, initial settings are not necessary.
Proceed to Section ‘7. Settings’ (p.53).

• Setting range: -10.000 to 10.000
Sensor correction• This corrects the input value from the sensor.
When a sensor cannot be set at the exact location where control is desired, thesensor-measured temperature may deviate from the temperature in the controlled
location. When using multiple controllers, sometimes the measured temperatures do
not concur due to differences in sensor accuracy or dispersion of load capacities. In
such a case, the control can be set at the desired temperature by adjusting the input
value of sensors. However, it is effective within the input rated range regardless ofthe sensor correction value.

2DOF PID control
Proportional gain 2DOF coefficient (α)• Sets Proportional gain 2DOF coefficient.
Increasing Proportional gain 2DOF coefficient (α) results in a quick response,and decreasing it causes a slow response.
• Setting range: 0.00 to 1.00
Available only when 2DOF PID control is selected in [Control method].

Integral 2DOF coefficient (β)• Sets Integral 2DOF coefficient.
By increasing Integral 2DOF coefficient (β), overshoot or undershoot can becontrolled more effectively.
However, response will be slower than the usual PID control for suppressing theovershoot or undershoot.
• Setting range: 0.00 to 10.00
Available only when 2DOF PID control is selected in [Control method].

2DOF PID Control
Two degree-of-freedom PID control has follow-up characteristics when SV is changed, and can
suppress disturbance.
Two degree-of-freedom means that the above 2 characteristics can be adjusted independently.
Follow-up characteristics when SV is changed, can be adjusted by setting the Proportional gain 2DOF
coefficient (α).
To suppress disturbance, Integral 2DOF coefficient (β) is used for adjustment.
The factory default values have been set at the optimum coefficients (α, β) for standard control.

Select PID control or ON/OFF control action in [OUT1 proportional band] in Sub setting mode.
If ‘OUT1 proportional band’ is set to 0 (zero), the unit performs ON/OFF control action.
Factory default value is PID control.
PID control
Proportional (P) action suppresses overshoot and hunting, Integral (I) action corrects offset,
and Derivative (D) action adjusts for rapid temperature change due to disturbance in shorter time.
Optimum values of P, I, D, ARW for PID control can be automatically set by performing AT.
ON/OFF control
When PV is lower than the SV, the control output is turned ON, and if PV exceeds the SV,
the control output is turned OFF.
Overshoot, undershoot and hunting are generated in ON/OFF control action.

Fixed value control is a typical temperature control action, which reduces deviation from a single SV
by comparing with PV.
To perform Fixed value control, set the SV.
There are 2 ways to set the SV.
• Set the SV in [SV1] in Initial setting mode.
• Set the SV in [SV1] in Main setting mode.
Setting item [SV1] in Initial setting mode corresponds to [SV1] in Main setting mode.
Therefore, if one SV1 is changed, the other SV1 will also be changed.
Factory default value is 0 (zero).

838.5 Setting PID Constants (by Performing AT)

Notice• Perform the AT during the trial run.
• During the AT, none of the setting items can be set.
• If power failure occurs during the AT, the AT stops.
• If AT is cancelled during the process, P, I, D and ARW values revert to the values before AT
was performed.
• AT will be forced to stop if it has not been completed within 4 hours.
• Sometimes the AT process will not fluctuate if AT is performed at or near room temperature.
Therefore, AT might not finish normally.

To set PID constants, perform AT.
There are 2 types of AT: Usual AT and ‘AT on Startup’
8.5.1 Usual AT
In order to set each value of P, I, D and ARW automatically, the AT process should be made to fluctuate
to obtain an optimal value.
For DC voltage, current inputs, the AT process will fluctuate around the SV for conditions of [A], [B] and[C] below.
One of 3 types of fluctuation below is automatically selected depending on the deviation between SV
and PV.
[A] If there is a large difference between the SV and PV as the temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.

8.5.2 AT on Startup
When usual AT cannot be performed normally due to temperature interference, P, I, D and ARWvalues can be calculated only when temperature is rising.
As the selected [AT on startup Perform] is internally memorized, ‘AT on startup’ is performed
whenever the power is turned ON.
To stop ‘AT on startup’, select ‘AT/AT on startup/Auto-reset Cancel’ in [AT/Auto-reset Perform/Cancel].

(Fig. 8.5.2-1)[Conditions of Performing ‘AT on startup’]• When starting ‘AT on startup’, if deviation between PV and SV exceeds the proportional band by
2 times or more, ‘AT on startup’ will perform.
When power is turned ON (*), or when the unit reverts to RUN mode after canceling control output
OFF, ‘AT on startup’ performs.
Even after ‘AT on startup’ is successfully finished, ‘AT on startup’ has been still selected in[AT/Auto-reset Perform/Cancel].
When power is turned ON again, or when the unit reverts to RUN mode by cancelling Control output
OFF, ‘AT on startup’ performs again under the above performance conditions.
To stop ‘AT on startup’, select ‘AT/AT on startup/Auto-reset Cancel’ in [AT/Auto-reset Perform/Cancel].
(*) For Fixed value control, ‘AT on startup’ can be performed when power is turned ON. It cannot be performed for
Program control.

85However, if PV slope and delay time cannot be measured normally for P, I, D calculation, the error
code below will be indicated on the PV Display, and automatically ‘AT on startup’ will stop.
If an error has occurred, P, I, D and ARW values revert to the previous value at which ‘AT on startup’is performed.
Error CodeError Contents
Normally PV slope and delay time cannot be measured for P, I, D calculation.

To cancel the error code, press thekey.
If ‘AT on startup’ is performed or stopped again, the error code will be cancelled.
[Conditions of Cancelling ‘AT on startup’]• When Control output OFF is enabled• When input is burnt out• When deviation between SV and PV is not within 2 or is not within 2% of proportional band

If AT or ‘AT on startup’ does not finish after 4 hours.

To cancel the error code, press thekey.
The error code will be cancelled in the following cases.
• When Control output OFF function is enabled• When Program control is stopped and the unit reverts to Standby (Program control waiting) mode.
• When ‘Control output OFF function’ or ‘Auto/Manual control’ is selected in [OUT/OFF key function].
• When ‘AT/AT on startup/Auto-reset Cancel’ is selected in [AT/Auto-reset Perform/Cancel].

868.6 Performing Auto-reset

Notice• Auto-reset finishes in approximately 4 minutes. It cannot be cancelled while performing
this function.
• If input is burnt out, Auto-reset will be forced to stop.

In PD control, Auto-reset is performed to correct the offset at the point at which PV indication isstabilized within the proportional band. Since the corrected value is internally memorized, it is notnecessary to perform the Auto-reset again as long as the process is the same.
However, when OUT1 proportional band (P) is set to 0 or 0.0, the corrected value is cleared to 0 (zero).

9.5 Using as a Converter

CautionInput/Output response time of this instrument is approx. 1 second.
When using as a converter, the converter input will be 1 sec slower due to the response time.
(In such cases please use a converter with input time slower than the response time above.)This instrument can be used as a simplified converter.
Converts each input value (thermocouple, RTD, DC voltage and current inputs) to ‘4 to 20 mA DC’,and outputs it.
When OUT1 is direct current output type, the controller can be used as a converter.
Select ‘Converter’ in [Controller/Converter] in Engineering mode 1.
Factory default value is ‘Controller’.
When this instrument is switched from controller to converter, values in the table below (Table 9.5-1)
are automatically set. The SV Display turns blank.
When this instrument is switched from converter to controller, the PV Display indicates

When the input is any other value except 4 to 20 mA DC
Input and output conditions:
Input: 6 to 14 mA DC (Indication: 30.0 to 130.0),
Output: 4 to 20 mA DC
Setting method(1) Calculating Scaling high and low limit values of 4 to 20 mA DC
Indication value per mA DC: (130.0 – 30.0) ÷ (14 – 6) = 100 ÷ 8 = 12.5
Scaling high limit value:
130.0 + (20 – 14) x 12.5 = 205.0
Scaling low limit value
30.0 – (6 – 4) x 12.5 = 5.0(2) Calculating OUT1 Proportional band of 6 to 14 mA DC (Slope setting)
OUT1 Proportional band (P) = {(14 – 6) ÷ (20 – 4)} x 100 = 0.5 x 100 = 50 (%)(3) Calculating SV (desired value) so that 4 mA DC output can be obtained from 6 mA DC input(Parallel shift setting)

signal wire for DC voltage(0 to 5 V DC, 0 to 10 V DC)
and direct current (0 to 20
mA DC) is disconnected.

Check whether the input
terminals for DC voltage(0 to 5 V DC, 0 to 10 V DC) or

Solution
Check the input signal wires of DC voltage (0 to 5
V DC, 0 to 10 V DC) and direct current (0 to 20
mA DC).
How to check whether the input signal wire is
disconnected[DC voltage (0 to 5 V DC, 0 to 10 V DC)]If the input to the input terminal of this controller is
1 V DC, and if a value (converted value from
scaling high, low limit setting) corresponding to
1 V DC is indicated, the controller is likely to be
operating normally, however, the input signal wire
may be disconnected.
[Direct current (0 to 20 mA DC)]If the input to the input terminal of this controller is
4 mA DC, and if a value (converted value from
scaling high, low limit setting) corresponding to 4
mA DC is indicated, the controller is likely to be
operating normally, however, the input signal wire
may be disconnected.
Connect the input terminals of DC voltage andcurrent to the input terminals of this instrument
securely.

Solution
Release the lock in [Set value lock].
If AT or ‘AT on startup’ is performing, cancel AT or‘AT on startup’.
Please wait until Auto-reset is finished.
