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).
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.

1, 2, 3... 1. To use Fahrenheit, set function selector 4 to ON, which is usually set to OFF.
2. Insert the internal mechanism into the case.
3. Turn on the E5J so that d-u will be displayed on the process value display.
Then press the Up Key so that fwill be displayed on the set value display.
4. Turn off the power in two seconds.
5. Draw the internal mechanism from the case and set function selector 4 to
OFF and turn on the E5J.

2-3-4 Standby Sequence
The alarm output is ON the moment the E5J is turned on because the process
value is within the alarm range. To prevent this, select a mode with a standby
sequence. If a mode with a await sequence is selected, the alarm output will not
be ON even if the process value is within the alarm range unless the process
value once goes out of the alarm range. The following diagram shows the opera-
tion of the E5J in lower limit alarm mode with a standby sequence.

It is possible to change the alarm hysteresis (set to 0.2°C before shipping) on the
engineering level.
2-3-5 Function Selector Settings
All the function selector pins are factory-set to OFF.

FUNCTION To set these pins to
ON, use a small flat-
blade screwdriver.
Refer to the following table for function switch setting.
Pin no. 1 2 3 4
Output Cooling operation (Normal) ON --- --- ---
operation Heating operation (Reverse) OFF
Control ON/OFF control --- ON See note
mode Advanced PID --- OFF ON
Advanced PID with fuzzy self-tuning --- OFF OFF
Level Engineering level --- --- --- ON
Normal operation --- --- --- OFF
Note The E5J will be in ON/OFF control mode regardless of the setting of pin 3 if pin
2 is set to ON.
Output Operation (Pin 1)
Heating Operation If pin 1 of the E5J is set to OFF, when the process temperature is lower than the
set point, the E5J will operate so that the heater output will increase.
Cooling Operation If pin 1 of the E5J is set to ON, when the process temperature is higher than the
set point, the E5J will operate so that the output of cooling water will increase.
Control Mode (Pins 2 and 3)
ON/OFF Control The ON/OFF control is also called two-position operation.
Advanced PID Set the E5J in this mode for P, PI, or PD control or if the most suitable PID
constants for the controlled device are already known.
Set the E5J in this mode so that Fuzzy self-tuning adjusts the PID constants to
the most suitable values according to the controlled device for ideal temperature
control. Refer to
Section 4 Fuzzy Self-tuning for details.
Level (Pin 4) Set pin 4 to ON if it is necessary to change any parameter on the engineering
level. Set this pin to OFF for normal operation.
