In the Setting Display for the PID parameters, Displays can
be arbitrarily switched using the Up, Down, Left or Right arrow
key. Pressing the Left or Right arrow key changes the group.

Note1: In Cascade control, the LP2 lamp is lit while the Loop-2 parameter is displayed.
There are eight groups of PID parameters.
In Cascade control, both Loop 1 and Loop 2 have eight groups.
The PID parameters can be selected by using the following two methods:
(1)SegmentPIDnumberselection
(2)ZonePIDselection
(3) Local PID selection
► Selection by contact input: 12.1 Setting Contact Input Function
► Selection by each Zone: 8.4 Switching PID
