Model Notations
“E5CN, E5CN-U, E5AN, and E5EN” is used when the information being provided applies to all E5CN-
@@@, E5CN-@@@U, E5AN-@@@, or E5EN-@@@ Digital Temperature Controllers. The notation used
in the manual (e.g., for model designations in SECTION 5 Parameters) for information that is restricted
by the model is given in the following table.
Note Supported for 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.
