There are four groups of PID parameters.
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
