Definitions:

• Set point: green line

• Operating window, green range: in

control

• Action window, orange range:

operator action required, pro-active

• Action window, red range: process not

in optimal condition, direct operator

action required, report and support.

• Operating window is always narrower

than the Safe Operating Window.
