-- Actual value and setpoint display
A red and a green analog display with 1.7% resolution and a red and a green 4
display are arranged on the front panel. The green displays are assigned to the setpoint, the
red displays to the actual value. In addition there is a 3-digit yellow digital display for the
y-display. The corresponding adjustment keys and status-LED's are assigned in color and
position to the displays.
The two analog displays always indicate the active actual value. The difference between the
two displays is the control difference xd or the control error xw = --xd. The digital actual value
display also indicates the current actual value except in the ratio controllers (ratio controller:
actual ratio). The digital setpoint display indicates the setpoint before the setpoint ramp
except in ratio controllers (ratio controller: nominal ratio before the setpoint ramp).
Depending on the controller type the displays, the Internal/External-key (2) and the
Δw-adjustment keys (6) are switched by the Shift key (12) controller I/controller II.
