Pressure control
Pressure Control - Manual Mode
In manual mode the operator has control over the motors. The pressure is
equal to the setpoint and does not change.
Only pressure sensor A: 5 bar (500 kPa / 73 psi)
Pressure Control - Key-to-line
NOTE: The graph does not change to adapt to the entered values.
Min. pressure: Pressure setpoint when the external line speed signal lies
below the entered value Line speed for min. pressure.
0 bar (0 kPa / 0 psi)
Fig. 4-103
Max. pressure: Pressure setpoint when the external line speed signal
exceeds the entered value Line speed for max. pressure.
80 bar (8000 kPa / 1160 psi)
Line speed for min./max. pressure: Line speed signal value in %, below
or above which the pumps begin to generate the set min./max. pressure.
Max: 100 %
Min: 0 %
