Conventions Used in This Manual
“E5@C” is used to indicate information that is the same for the E5CC, E5CC-U, E5CC-B, E5EC,
E5EC-B, E5AC, E5DC, E5DC-B, and E5GC Digital Controllers. “E5@C-B” is used to indicate informa-
tion that is the same for the E5CC-B, E5EC-B, and E5DC-B Digital Controllers. “E5EC/E5AC-PR@” or
“Position-proportional Models” indicates the Digital Controllers with position-proportional control. “Stan-
dard Models” indicates other Digital Controllers.
The following abbreviations are used in parameter names, figures, and other descriptions. These
abbreviations mean the following:
* “EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C, m, and g.
The size of the EU depends on the input type. For example, when the input temperature setting range is −200
to 1,300°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 the EU depends on the decimal point position of the scaling setting, and 1 EU is
the minimum scaling unit.
