Preface
The E5CN, E5CN-U, E5AN, E5EN, and E5GN are Digital Temperature Controllers. The E5CN and
E5CN-U are both compact temperature controllers, with the E5CN featuring screw terminal connec-
tions, and the E5CN-U featuring socket pin connections. The E5GN can be connected using screw ter-
minals or screwless clamp terminals. The main functions and characteristics of these Digital
Temperature Controllers are as follows:
• Any of the following types of input can be used: thermocouple, platinum
resistance thermometer, infrared sensor, analog voltage, or analog cur-
rent.
• Either standard or heating/cooling control can be performed.
• Both auto-tuning and self-tuning are supported.
• Event inputs can be used to switch set points (multi-SP function), switch
between RUN and STOP status, switch between automatic and manual
operation, start/reset the simple program function, and perform other
operations. (Event inputs are not applicable to the E5CN-U.)
• Heater burnout detection, heater short (HS) alarms, and heater overcur-
rent (OC) functions are supported. (Applicable to E5CN, E5AN, E5EN,
and E5GN models with heater burnout detection function.)
• Communications are supported. (Applicable to E5CN, E5AN, E5EN, and
E5GN models with communications.)
• User calibration of the sensor input is supported.
• The structure is waterproof (IP66). (Not applicable to the E5CN-U.)
• Conforms to UL, CSA, and IEC safety standards and EMC Directive.
• The PV display color can be switched to make process status easy to
understand at a glance.

1) It takes approximately two seconds for the outputs to turn ON from after the power supply is turned ON.
Due consideration must be given to this time when incorporating Temperature Controllers into a control
panel or similar device.
2) Make sure that the Temperature Controller has 30 minutes or more to warm up after turning ON the power
before starting actual control operations to ensure the correct temperature display.
3) When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Temperature Controller. If power is turned ON for the Temperature Controller
before turning ON power for the load, self-tuning will not be performed properly and optimum control will
not be achieved. When starting operation after the Temperature Controller has warmed up, turn OFF the
power and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the
Temperature Controller OFF and ON again, switching from STOP mode to RUN mode can also be used.)
4) Avoid using the Controller in places near a radio, television set, or wireless installing. The Controller may
cause radio disturbance for these devices.
The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with Lloyd's standards. When applying the
standards, the following installation and wiring requirements must be met in the application.
■Application Conditions
1) Installation Location
The E5CN, E5CN-H, E5AN, E5AN-H, E5EN, and E5EN-H comply with installation category ENV1 and
ENV2 of Lloyd's standards. Therefore, they must be installed in a location equipped with air condition-
ing. They must therefore be installed in a location equipped with air conditioning. They cannot be used
on the bridge or decks, or in a location subject to strong vibration.
2) Wiring Conditions
Install the recommended ferrite core and wrap the line around it three turns for the applicable lines
(e.g., power supply cable line and signal lines) of the models listed in the following table. (See illustra-
tions.) Install the ferrite cores as close to the terminal block of the E5@N as possible. (As a guideline,
the ferrite core should be within 10 cm of the terminal block.)

Conventions Used in This Manual
Model Notation
The E5CN-@@@, E5CN-@@@U, E5AN-@@@, E5EN-@@@, and E5GN-@@@ are given as the E5CN,
E5CN-U, E5AN, E5EN, and E5GN when they share functionality.
The following notation is used when specifying differences in functionality.
Note: (1) Excluding the E5GN.
(2) Excluding the E5CN.
(3) The E5AN and E5EN only.
Meanings of Abbreviations
The following abbreviations are used in parameter names, figures and in text explanations. These
abbreviations mean the following:
Note: (1) A heater short indicates that the heater remains ON even when the control output from the Tempera-
ture Controller is OFF because the SSR has failed or for any other reason.
(2) “EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C,
m, and g. The size of EU varies according to the input type.
For example, when the input temperature setting range is –200 to +1300°C, 1 EU is 1°C, and when
the input temperature setting range is –20.0 to +500.0°C, 1 EU is 0.1°C.
For analog inputs, the size of EU varies according to the decimal point position of the scaling setting,
and 1 EU becomes the minimum scaling unit.

Names of Parts Section 1-1
1-1-3 Using the Keys
This section describes the basic functions of the front panel keys.
PF (Function (Auto/
Manual)) Key
(E5AN/EN Only)
This is a function key. When it is pressed for at least 1 second, the function set
in the PF Setting parameter will operate.
Example: When A-M (auto/manual) is selected in the PF Setting parameter
(initial value: A-M), the key operates as an auto/manual switch, switching
between Auto Mode and Manual Mode. If the key is pressed for more than 1
second (regardless of key release timing), the mode will switch.
OKey Press this key to move between setting levels. The setting level is selected in
the following order: operation level: adjustment level, initial setting level, com-
munications setting level.
MKey Press this key to change parameters within a setting level.
The parameters can be reversed by holding down the key (moving one per
second in reverse order).
UKey Each press of this key increments the value displayed on the No. 2 display or
advances the setting. Holding the key down speeds up the incrementation.
DKey Each press of this key decrements values displayed on the No. 2 display or
reverses the setting. Holding the key down speeds up the incrementation.
O+ MKeys Press these keys to change to the protect level. For details on operations
involving holding these keys down simultaneously, refer to 1-3 Setting Level
Configuration and Key Operations.
O+ UKeys
O+ DKeys
To restrict set value changes (in order to prevent accidental or incorrect oper-
ations), these key operations require simultaneously pressing the Okey
along with Uor Dkey. This applies only to the parameter for the password to
move to protect level.
