CUSTOM PRESSURE
This feature allows customer set required pressure independently on
HI/LO mode. The main reason for implementation is to reduce fuel
consumption as much as possible by setting the exact pressure value
required.
The machine is equipped with an additional pressure regulator and
solenoid valve.
Custom pressure activation controls outlet pressure and engine speed.
Settings (described for 7/124-10/110 unit):
Set Custom pressure value between HI/LO mode pressure, e.g 9 bar
and activate function.
Machine operates in HI mode, pressure drops from 10 to 9 bar and
engine speed remains the same.
Machine operates in LO mode, pressure drops to 7 bar (nominal
pressure) and engine speed rises to 2200 rpm.
Switch to HI mode, pressure rises to 9 bar and engine speed drops to
1950 rpm.
