PID Operation Operating Instructions
3.4 Area Switching Automatic Operation
(LOC/AUT Mode)
In the previous section, only one area (AG01) is used for the target control.
This section describes how to set up to 8 areas as needed. It also describes
how to select the area number for operation.

Press .
The panel looks like the example at right:
PV: Area group symbol (AG 1)
SV: Target set value of the area
Symbol: Symbol for the target setting (SV)

Change the setting value of each item as desired.
(See page 48 for the items you can set for each area)
a. Change the value by pressing or .
b. Register the value by pressing .
c. Go to the next item by pressing .
d. Repeat steps a to c for all the items.
Note: Press only when you do not need to
alter the value in these steps.
* You can use Auto-tuning to set PID constants
instead of manual setting in the Auto-tuning PID
operation. Refer to "Procedure-2 Setting the PID
Constants with Auto-tuning" on page 40.

Press to move to Area No. 2.
Area Group 2 (AG 2) will appear as shown at right.
Set all items in the group as described in step
.

Repeat steps
1
to 3 above to set as many AREA groups as you want to use.
* Each AREA must have its optimal PID constants.
