Model Notation

"E5@C" is used to indicate information that is the same for the E5CC, E5EC, and E5AC Digital Control-
lers. "E5EC/E5AC-PR@" or "Position-proportional Models" indicates the Digital Controllers with posi-
tion-proportional control. "Standard Models" indicates other Digital Controllers.
Meanings of Abbreviations
The following abbreviations are used in parameter names, figures, and other descriptions. These
abbreviations mean the following:
Symbol
PV Process value
SP Set point
SV Set value
AT Auto-tuning
ST Self-tuning
EU Engineering unit*
LBA Loop burnout alarm
HB Heater burnout
HS Heater short
RSP Remote SP
LSP Local SP
"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.
000 : Indicates items that can be used only with the E5@C-@-0@.
