Selection of the operating state

With this pump, you can choose between the following operating states:
1. Four characteristic curves with fixed rotation speeds
2. Four characteristic curves with regulation in the proportional-pressure process
The pump is adjusted ex-works to the highest constant stage.
After a reset (Page 31), the pump also starts at this stage.
As a result of continuous pressing of the key, the characteristic curve is changed. The four
constant stages are run through first of all. The LED's light up permanently with these stages.
For stage I one LED lights up, for stage II 2 LED's light up, for stage III 3 LED's light up and for
stage IV 4 LED's light up. Then the stages follow with proportional control. With these stages,
only the LED near the corresponding adjusted symbol step.
