1-1 Features
The basic features of the Thermac E5
J Temperature Controller are outlined
below.

Fuzzy Self-tuning When using a conventional temperature controller for ideal temperature control,
it is necessary to adjust the PID constants of the temperature controller accord-
ing to the controlled device. The Thermac E5
J Temperature Controller incor-
porates a fuzzy self-tuning function, thus allowing ideal temperature control
without any adjustment of the PID constants. The user needs only to set the
E5
J to the desired temperature for ideal temperature control.

Auto-tuning Auto-tuning is also available. It is useful when appropriate results are not
obtained through fuzzy self-tuning. (Refer to Section 10 Auto-tuning.)

Event Input Function It is possible to select a set point out of a maximum of two set values on the
E5CJ-
B and four set values on the E5AJ-
B via their event input terminals
from the PCs connected to these Temperature Controllers. The control opera-
tion of the E5AJ-
B via can be stopped with an event input signal.

Watertight Construction The E5
J can be used in places where water is sprayed onto the E5
J, be-
cause the front panel of the E5
J assures IP54 when the E5
J is panel-
mounted (except for front panel of the E5CJ, which assures IP50). If greater wa-
tertightness is required, use the Y92A-

N, a dedicated watertight cover (sold
separately).

Advanced PID The E5
J incorporates an advanced PID function, which is also incorporated by
the Thermac X Temperature Controller. The advanced PID function prevents
temperature overshooting the moment the Temperature Controller starts oper-
ating, assures a short startup time, and performs ideal temperature control by
quickly responding to external disturbances.

Output Units The E53-R Relay Unit, E53-Q, E53-Q3, and E53-Q4 Voltage Output Units for
driving SSRs, and E53-C3, E53-C3D, E53-V34, and E53-V35 Linear Output
Unit can be connected to any E5
J Temperature Controller (except the E5CJ)
with ease according to the desired output configuration and application.

o Output Value Display The output value is displayed within a range of 0.0% to 100.0%.
cp Control Period Setting It is possible to set the control period within a range of 1 to 99 s. The control peri-
od is the period required by the E5
J to turn ON and OFF its relay output or volt-
age output. The ON period increases in proportion to the output value. If the con-
trol period is short, smooth control operation will be possible although a short
control period shortens the life of the relay if relay output is used. Therefore, the
control period should not be less than 20 s if relay output is used. The following
are output examples with an output value of 50.0 %.

4-1 Fuzzy Self-tuning Operation

The fuzzy self-tuning function has three features, step response tuning (SRT),
disturbance tuning (DT), and hunting tuning (HT).

4-1-1 Step Response Tuning (SRT)

SRT is used to obtain all PID constants using a step response method when the
Temperature Controller starts operations.
SRT is also used when the set point changes value exceeding a set range while
the Temperature Controller is operating. After SRT has been executed, no SRT
will be executed the next time the Temperature Controller starts operating, un-
less the set point has been changed.

Note Be sure to turn on the power supply to the load either before or simultaneously
with the start of Temperature Controller operation. When using the E5AJ-A2HB
or E5EJ-A2HB, you can change the RUN/STOP setting to RUN via event input
2 after supplying power to the load.
Dead time will be measured from the time the Temperature Controller starts
operating. If a load such as a heater is turned on after the Temperature Control-
ler is turned on, dead time longer than the actual value will be measured and
inappropriate PID constants will be obtained. If an extremely large amount of
dead time is measured, the control amount will be set to 0% for a short period of
time before being returned to 100%, and the constants will then be retuned.
Retuning is performed only for large amounts of dead time, so be sure to follow
the precaution given above when starting operation.

from advanced PID control to advanced PID control with fuzzy self-tuning.

applied when the deviation becomes smaller than this value.

PID Constant Refreshing If the step control amount is applied before the maximum temperature slope (R)
Conditions is obtained, SRT will not renew any PID constant. If the proportional band ob-
tained from the R and L values that were measured before the imposition had
been completed is larger than the present proportional band, the PID constants
will be renewed because the measured value is in the direction towards the suit-
able proportional band value, and the set point at that time will be the SRT-
executed set point.

4-1-2 Disturbance Tuning (DT)

DT is used to measure the control waveform and adjust the PID constants when
the measured temperature becomes unstable. When there are control charac-
teristic changes after the PID constants are refreshed with SRT or when the PID
constants are not suitable to the object to be controlled because SRT was not
executed, the PID constants will be adjusted with DT.

DT at the Time of Operation If there is overshooting at the time the Temperature Controller restarts operating
Start and Set Value Change after SRT has been executed, DT adjusts the PID constants so that the set point
response waveform will be as close as possible to the most ideal response wa-
veform after it is deemed that there has been a characteristics change in the con-
trol system.

Startup Conditions of DT DT is used to monitor the control waveform if there is external disturbance or
SRT does not work at the time the Temperature Controller starts operating or at
the time of set point change. If the measured waveform is not an ideal waveform,
DT will be ON. If either one of the following conditions is satisfied, the control
waveform will be monitored.

1, 2, 3... 1. SRT Startup conditions 3 and 4 on page 29 are satisfied but neither 1 nor 2 is
satisfied.
2. There has been an external disturbance exceeding the stable range after
the process value was in stable condition.

Note The stable range is set to 27°F with the E5
J-

4-1-3 Hunting Tuning (HT)

If there is hunting due to characteristics changes of the control system, HT is
used to measure the hunting waveform and adjust the PID constants to sup-
press the hunting.

values while SRT is not being executed.

Note If the periodic temperature changes of the application exceed the stable range
(set to 15.0°C at the factory) due to continuous external disturbance (i.e., the
temperature is affected by an external disturbance before stabilizing after a pre-
vious external disturbance (refer to figure A below)), the user should change the
stable range to a value greater than the temperature changing range, otherwise

30
Troubleshooting Section 4-2

HT may change the PID constants even though the PID constants are ideal for
the control system. Refer to 9-1 Engineering Level for details.

4-3 Terminology

4-3-1 Stable Value, Stable Range, and Stability Judgement Time

If the measured value continuously coincides with the set point, it can be said
that the measured value is stable. The measured value will not continuously
coincide perfectly with the set point if there is noise inference. It is, however, pos-
sible to make the measured value stay within a permissible range called the
stable range. Even if the temperature is within the stable range, the Temperature
Controller may respond to external disturbance or hunting. Therefore, it cannot
be said that the temperature is stable unless the temperature stays within the
stage range continuously for a certain time. This time is called stability judge-
ment time. Like PID constants, stability judgement time is adjusted with fuzzy
self-tuning according to the characteristics of the object to be controlled. Fuzzy

4-3-2 Hunting
If the PID constants are not suitable to the controlled device, the measured value
will fluctuate and will not coincide with the set point, this phenomenon is called
hunting. Hunting is also called cycling.

Set point

4-3-3 Characteristics and Characteristics Change

The angle of the maximum temperature slope (R) of the controlled device (i.e.,
whether the temperature rise of the device is fast or slow) and the dead time (L)
of the controlled device (i.e., how fast the change in the output of the Tempera-
ture Controller influences the temperature) vary with the characteristics of the
controlled device. The PID constants must be set according to the characteris-
tics of the controlled device. A characteristics change is the change of the char-
acteristics of the controlled device due to the change of its thermal capacity and
the change of the supply voltage. If there is a characteristics change, the PID
constants must be adjusted according to the new characteristics.

4-3-4 External Disturbance

External disturbance is an external factor that disturbs the temperature that has
been stable within the most ideal PID constants for the controlled device.

4-3-5 Interference
If devices, such as heaters, controlled by different temperature controllers are
physically close to one another, the heaters are mutually influenced and the tem-
perature of each heater are affected. This phenomenon is called interference. If
there is serious interference, it will be difficult for each temperature controller to
control the device, and special controlled methods taking this interference into
consideration will be required.

33
Terminology Section 4-3

4-3-6 Startup
Startup means that the Temperature Controller starts operating. The following
conditions are required to operate the Temperature Controller.
• The Temperature Controller must be turned ON.
• No sensor error has occurred.
• If a model with event input 2 is used, event input 2 must be set to RUN.
Event input 2 is set to RUN before shipping.
The Temperature Controller will not start operating until all the above conditions
are satisfied.

Heater Burnout Procedures Section 8-2

8-1 Heater Burnout Detection

To detect heater burnout, wire one of the lead wires for each heater through the
hole of the Current Transformer (CT). The CT generates an AC current accord-
ing to the current flow of the lead wire. The Thermac E5
J Temperature Control-
ler measures the AC current to check the current flowing to the heater. If any one
of the heaters burns out, the AC current value will decrease so that the E5
J
turns its heater burnout alarm ON, comparing the AC current value with the heat-
er burnout alarm value.

8-2 Heater Burnout Procedures

The E5
J starts heater burnout detection from the moment the E5
J is turned
on. If any one of the heaters is turned on after the E5
J is turned on, the heater
burnout alarm output will be ON because the E5
J judges that the heater is
burnt out. Therefore, all the heaters must be turned on simultaneously with the
E5
J or before the E5
J is turned on. This is essential for smooth temperature
control and fuzzy self-tuning.
The E5
J will continue temperature control even if the heater burnout alarm is
ON because the E5
J will continue temperature control using the heaters that
are not burnt out.
Heater burnout detection is possible when the control output is ON. No heater
burnout detection is, however, possible if the control output is ON for less than
190 ms.
The heater burnout alarm output will be held once the heater burnout is de-
tected. To reset the heater burnout alarm output, replace the burnout heater with
a good one and take one of the following steps.
1, 2, 3... 1. Set the heater burnout alarm value to 0.0 A.
2. Turn the E5
J off and on.
If the difference between the normal heater current value and heater burnout
current value is comparatively small, heater burnout detection will not be stable.
For stable detection, the difference must be 1.0 A minimum if the heater current
consumption is less than 10.0 A and 2.5 A minimum if the heater current con-
sumption is 10.0 A or more.
Heater burnout detection is not possible if the E5
J has current output, the
heater current is DC, or three-phase heaters are used.
Use the K2CU-F

A-
GS (with gate input terminals) for three-phase heater
burnout. Refer to the K2CU-F

A-
GS data sheet specifications for details.
If no heater burnout detection is executed or if no CT is used, set the heater burn-
out alarm value to 0.0 A. The heater burnout alarm value is factory-set to 0.0 A.

8-4 Heater Burnout Alarm Value

To obtain the proper heater burnout alarm value, check the normal heater cur-
rent value and heater burnout current value with the heater current value display
on display level 1 first and set the heater burnout alarm value to the mean value
of these two values. If more than one heater is used, check the burnout value of
the heater with the smallest current consumption value.

Normal heater + Heater burnout

Heater burnout current value current value
=
alarm value
2

If the difference between the normal heater current value and heater burnout
current value is comparatively small, heater burnout detection will not be stable.
For stable detection, the difference must be 1.0 A minimum if the heater current
consumption is less than 10.0 A and it must be 2.5 A minimum if the heater cur-
rent consumption is 10.0 A or more.

If normal current value  10.0 A

Then normal current value – heat burnout current value  1.0 A
If normal current value  10.0 A
Then normal current value – heater burnout current value  2.5 A

The heater burnout alarm value can be set within a range of 0.0 to 50.0 A. If the
alarm value is set to 0.0 A or 50.0 A, no heater burnout detection is possible. The
alarm output is always OFF if the alarm value is set to 0.0 A and always ON if the
alarm value is set to 50.0 A.

51
Heater Burnout Alarm Value Section 8-4

The normal heater current value should be 50.0 A max. The heater current value
can, however, display up to 55.0 A. If the current value exceeds 55.0 A, CT input
overflow will result and ffff will be displayed.

8-4-1 Setting Examples

Example 1 In this example, 1-kW, 2-kW, and 3-kW heaters at 200 VAC are connected in par-
allel.
1, 2, 3... 1. Turn the control output ON and check the normal heater current value from
the heater current value display.

output ON

Disconnect

Normal current – heater burnout current = 30.0 – 25.0 = 5 A ( 2.5 A)

3. Set the heater burnout alarm value to the mean value of the normal current
value and heater burnout current value.
Heater burnout alarm value = (30.0 + 25.0)  2 = 27.5 A

Example 2 In this example, 400-W, 1700-W, and 2000-W heaters at 200 VAC are con-
nected in parallel and the difference between the normal current value and heat-
er burnout current value is less than 2.5 A.
1, 2, 3... 1. Obtain the normal current value and heater burnout current value in ad-
vance as follows:
Normal current = (400 + 1700 + 2000)  200 = 20.5 A
Heater burnout current = 20.5 – 400  200 = 18.5 A
Normal current – heater burnout current = 20.5 – 18.5 = 2.0 A (Stable detec-
tion is not possible because the value is not 2.5 A or more.)
2. For stable hater burnout detection, in such a case, increase the number of
turns of the wire passing through the CT as if apparent current value in-

52

creases. The displayed heater current value increases in proportion to the

number of turns of the wire passing through the CT.

3. Obtain the heater burnout alarm value using the method in example 1.

current value

Apparent heater burnout current = (41.0 – 400  200) x 2 = 37.0 A
