5.4   Enter Switchpoint Overpressure  

Select  

 

in the display using „OK“. The overpressure range is from 0.8 mbar to 

25 mbar and can be adjusted in steps of 0.05 mbar by turning the Wheel Shuttle. If you press 
„OK“ while turning the Wheel Shuttle, the step size is 1 mbar. Save the selected value by 
pressing „OK“. Factory presetting is 15.0 mbar. 

The display now shows the saved value: 

 

 

Confirm  the  displayed  value  by 

pressing „OK“ again. 

Turn the Wheel Shuttle clockwise or counterclockwise to continue the parametrization. 
 
 
 
 
 
 
 
 

5.5   Enter min. Volume Flow 

Select   

 

in the display using „OK“. The minimum volume flow range is from 0.1 

to 99.9 litres/sec. and can be adjusted in steps of 0.1 liters/sec. by turning the Wheel Shuttle. 
If you press „OK“ while turning the Wheel Shuttle, the step size is 1 ltr/s. Save the selected 
value by pressing „OK“. Factory presetting is 0.3 ltr/s. 

Turn the Wheel Shuttle clockwise or counterclockwise to continue the parametrization.
