abbreviations mean the following:
Note: (1)
A heater short indicates that the heater remains ON even when the control output from the Temper-

(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.
