0320
0320 REG. MODE
Regulation mode
normal
Possible settings: normal, inverse
Normal: Speed is increased with falling actual value signals. (e.g.: control at constant output pressure)
Inverse: Speed is reduced with falling actual value signal. (e.g.: control at constant suction pressure or at
constant level on the suction side)
0325
0325 FRQ. LIFT
Frequency limit for required lift value
30.0 Hz
Possible settings: 0.0 Hz – 70.0 Hz
Control according to a system curve (increase of the set pressure, depending on the ow rate/speed to
cover friction losses).
The setting determines the output-frequency where the set pressure starts to be increased. The right set-
ting should be equal to the frequency when the pump reaches the set pressure at zero ow (Can be deter-
mined by using the JOG MODE [0305]).
0330
0330 LIFT AMOUNT
Lift amount for required lift value
0.0 %
Possible settings: 0.0 – 200.0%
This value states how much the set value should be continually increased, till the maximum speed (maxi-
mum volume) is reached.
Application Example:
1) Enter the set pressure (see main menu
parameter REQ. VAL [02]).
2) Find out the frequency where set pres-
sure is reached at zero demand (use JOG
MODE [0305]) and set the value in param-
eter FREQU. LIFTING.
3) Set desired lift at maximum speed in % of
the set pressure in the parameter LIFT-
AMOUNT [0330].
A … set pressure
B … window
C … lift intensity in % of set pressure
