Operating level
While in operation, the controller is in the operating level. Key information on the control
process is displayed in this level. The default reading shows the controlled variable X, error
Xd, the currently valid set point W, W2 or WE, the active limit relay as well as information
on the three-step output, if applicable (see Fig.9-1).
Other variables, such as the error Xd in %, can be displayed instead of the currently valid set
point. In this case, press the selector key until the required variable is displayed. The follow-
ing variables can be selected: internal set point W, manipulated variable Y, error Xd% and,
depending on the conguration in the SETP menu, the internal set point W, W2 and the ex-
ternal set point WE.
