CHAPTER 5 PARAMETERS
E5CK
5--10
AT Execute/Cancel
Conditions of Use
The controller must be in operation, con-
trol must be advanced PID control, and ST
must be set to OFF.
•
Selects the limit cycle of MV change width (40% or 100%) for execution. After AT
execution, the “PID” and the “LBA detection time” (LBA: Loop Break Alarm) param-
eters are set automatically.
•
During heating and cooling control, only 100%AT can be executed.
•
When this parameter is selected, the setting becomes [
].
•
To execute 40%AT, select [
], and to execute 100%AT, select [
]. During
execution of auto-tuning, the AT LED flashes. However, note that during heating and
cooling control, [
] is not displayed.
•
When AT execution ends, the parameter setting automatically returns to [
].

“LBA detection time” (level 2 mode)
Set point 0
Set point 1
Conditions of Use
The multi-SP function must be in
operation.
•
When event input is OFF, the “set point 0” parameter is used, and when ON, the “set
point 1” parameter is used.
•
When the “set point” parameter has been changed, the setting of whichever is
selected in event input, “set point 0” or “set point 1”, is linked and changed.
•
The decimal point position is dependent on the selected sensor during temperature
input and on the results of scaling during analog input.
