Adjust the PID constants.
You can automatically or manually set the PID constants that are used for PID control.
Adjusting the PID Constants
The suitable values of the PID constants that are used for temperature control depend on the
characteristics of the controlled object.
There are three ways that you can use to set the PID constants. These are described
below.
If you ca n allow the temperature to vary while tuning the PID
constants and you need to calculate the optimum PID constants:
⇒
Use autotuning (AT).
If you know the PID constants in advance:
⇒
Set the PID constants
manually.
⇒
Use self-tuning (ST).
If you cannot allow the temperature to vary and you need to
automatically estimate the PID constants when the set point is
changed:
With self-tuning, calculation of the PID constants is affected by
changes in the temperature, such as when a heater is turned
ON and OFF. The PID c onstants will be automatically
calculated and set. If there is an external source that causes
temperature changes (such as a heater turning OFF), u se
autotuning or set the PID constants manually.

Problems with 100% Autotuning (AT-2)
If autotuning at 100% (AT-2) does not produce the desired results, you can also execute autotuning at
40% (AT-1).
●Autotuning at 40% (AT-1)
A 40% variation in the manipulated variable of the limit cycle is used for autotuning. Executing 40%
autotuning may require more time than executing 100% autotuning (AT-2).
The limit cycle timing varies according to whether the deviation (DV) at the start of autotuning execution is
less than 10% FS.

What Is a Standby
Sequence For?
Particularly with a
lower-limit alarm, the
temperature is often below
the alarm point when
temperature control is
started. In this case, an
alarm would be output at
the start of operation. To
prevent this, a standby
sequence is used to disable
the first alarm.

Sequence
Alarm output turns ON because temperature is

In the default settings, the standby sequence is restarted (and
the alarm is turned OFF) when operation is started, when the
SP is changed, or when the alarm temperature is changed.
You can change the conditions for restarting the standby
sequence.

Setting Temperature Alarms
Determining the Alarm Value

What Value Is Set for an Alarm?
You set the temperature at which the alarm is output. There are two methods to set the temperature for
the alarm types selected on pages 4-3 and 4-4: a deviation or an absolute temperature. Either positive or
negative values can be set for the alarm value.
●Setting Deviations from the Set Point
• Setting an Upper-limit Alarm (Alarm Type 2)
Example: Alarm Value = 20
• Setting a Lower-limit Alarm (Alarm Type 3)
Example: Alarm Value = 20
Alarm value: 20°C
Alarm value: 20°C

Alarm lower limit: 20°C
Alarm upper limit: 30°C
Alarm ON
80°C or lower

Set point:

●Setting Absolute Temperatures
• Setting an Absolute-value Upper-limit Alarm
(Alarm Type 8)
The alarm output will turn ON when the alarm value
is exceeded regardless of the value of the set point.
Example: Alarm Value = 100
• Setting an Absolute-value Lower-limit Alarm
(Alarm Type 9)
The alarm output will turn ON when the temperature
is below the alarm value regardless of the value of
the set point.
Example: Alarm Value = 100
Alarm value: 100°C
Alarm value: 100°C

Setting Heater Burnout Alarms
Setting Heater Burnout Alarms
The procedure to output heater burnout alarms is given step by step in this section.
A heater burnout alarm operates by detecting the heater current with a current transformer (CT). If
the detected current is less than the specified heater burnout detection current even though the
control output is ON, a heater burnout will be assumed and an alarm will be output. A heater burnout
alarm can be used only with a Controller that supports HS and HB alarm detection.
