tracking takes place at S45 = 0 and S43 = 1 to the control variable x, the tracking does not apply for switchover
wi1/wi2 at S45 = 1 automatic mode starts with wi=x (xd=0), the active setpoint runs to the old set value via the
possibly set setpoint ramp tS

Switching between wi1 and wi2

With the Shift key (6) the digital x/w-display can be switched between the display levels I to
IV depending on the position of S81.
In display level II the active w can be displayed, in display level III the main control variable
x1. The inactive setpoint is displayed in the display level IV . The displayed active or inactive
setpoint can also be adjusted (see table 3-2).
The active setpoint- and actual value is displayed on the analog displays.
