Output diagram wihout group control
If the setting signal or the control deviation exceeds the switch-on point of group 2, group 1 is reduced
to
“
n-min at Group2
”
. From here on both groups run parallel at maximum power.
If group control is activated (A Function =
|
5A
|
) the gradient of the output curve is automatically
increased by factor 1.4 (gradient without group control = 1).
