Name Description
Modify index
Linearization points can be deleted or added.
The configured index defines which lineariza-
tion point gets deleted resp. after which linea-
rization point a new point gets added.
% / rpm
Calibration is done by entering the velocity
[%] and the rotations per minute [rpm] for each
linearization point.
Back pressure
Name Description
Points Number of points in the linearization table.
Actual pressure Displays the actual back pressure.
Start Index
Since only a maximum of 9 linearization points
can be displayed on the mask, this field serves
for navigation purposes. The input value al-
ways corresponds to the index of the element
displayed first. Example: Value 1: linearization
points 1 to 9 are displayed. Value 17: lineari-
zation points 17 to 25 are displayed, etc.
Modify index
Linearization points can be deleted or added.
The configured index defines which lineariza-
tion point gets deleted resp. after which linea-
rization point a new point gets added.
V / bar
Calibration is done by entering the pressure
[bar] and the voltage [V] for each linearization
point.
Set output voltage
Possibility to force the set-voltage for the ana-
log output for pump pressure. For each linea-
rization point, the forcing of the analog output
voltage can be activated by entering '1'.
The resulting pump pressure is shown in field
'Act. pressure' and can be entered for the cor-
responding linearization point.
Limits
Field Description
Max. voltage analog output
Maximum output voltage for pump velocity and
pump pressure during calibration.
Min. voltage back pressure output
Minimum output voltage for pump back pres-
sure during calibration.
Analog output dither settings
With this function a small sinus signal can be added to the analog output for
back pressure. Thus the actuated valve is minimally kept in motion in order to
react faster when set values for the analog outputs change.
