0325<br />
0325 FRQ. LIFT<br />
30.0 Hz<br />
Possible settings: 0.0 Hz – 70.0 Hz<br />
Frequency limit for required lift value<br />
Control according to a system curve (increase of the set pressure, depending on the flow rate/speed to<br />
cover friction losses).<br />
The setting determines the output-frequency where the set pressure starts to be increased. The right<br />
setting should be equal to the frequency when the pump reaches the set pressure at zero flow (Can be<br />
determined by using the JOG MODE [0305]).<br />
0330<br />
0330 LIFT AMOUNT<br />
0.0 %<br />
Possible settings: 0.0 – 200.0%<br />
Lift amount for required lift value<br />
This value states how much the set value should be continually increased, till the maximum speed (maximum<br />
volume) is reached.<br />
Application Example:<br />
1) Enter the set pressure (see main menu<br />
parameter REQ. VAL [02]).<br />
2) Find out the frequency where set pressure<br />
is reached at zero demand (use<br />
JOG MODE [0305]) and set the value in<br />
parameter FREQU. LIFTING.<br />
3) Set desired lift at maximum speed in % of<br />
the set pressure in the parameter LIFT-<br />
AMOUNT [0330].<br />
A … set pressure<br />
B … window<br />
C … lift intensity in % of set pressure<br />
