CHAPTER 1 INTRODUCTION
E5EK
1--6
Control outputs 1 and 2 are used depending on the differences in con -
trol method as follows.
Control Method
Model
Control Output 1/
Control Output 2
Standard control E5EK-AA2 AC100-240
E5EK-AA2 AC/DC24
Control output (heat) /
Alarm, etc.,
Heating and cooling

E5EK-AA2 AC100-240
E5EK-AA2 AC/DC24
Control output (heat) /
Control output (cool)
Position-proportional
control
E5EK-PRR2 AC100-240
E5EK-PRR2 AC/DC24
Open/Close
The E5EK supports the following six transfer outputs.
Set p oint
Set p oint during SP ramp
Process value
Heating side manipulated variab le
Cooling side manipulated variable
Valve opening
However, note that heating/cooling side manipulated variables can be
output only standard type controllers, and valve opening can be output
on position-proportional type controllers
These transfer outputs can be output after being scaled. Setting of an
upper limit value smaller than the lower limit value is allowed, so
reverse scaling can also be carried out.
