Check LookAhead pressure regulation at speed change
1. Press button for pressure regulation on the Controller. Check
that fly-leg icon appears in upper left corner of the display.
2. Go to menu [4.6 speed simulation]. Key in e.g. 9 km/h and press
to use the value. Stay in this menu (i.e. do not press ESC to leave).
3. Start PTO at nominal RPM.
4. Press main ON/OFF to ON, to open all sections. Check that the
pressure regulation valve rotates and that pressure stabilises at 5
bar.
5. In menu [4.6 speed simulation]. Key in e.g. 6 km/h and press to
use value. Check that pressure regulation valve rotates and that
pressure stabilises at 2 bar.
6. When pressure regulation valve is stable (i.e. does not rotate/
adjust), then wait 30 seconds before proceeding.
7. Press main ON/OFF to OFF, to close all sections.
8. Go to menu [4.6 speed simulation]. Key in e.g. 9 km/h and press
to use the value. Check if pressure regulation valve rotates
counterclockwise (to reduce pressure) immediately after pressing . If pressure regulation valve rotates when all
sections are closed, then LookAhead is activated and works correctly.
9. Press main ON/OFF to ON, to open all sections. After a delay of approx. 3 sec the pressure regulation valve begins
rotating to adjust actual flow to set flow.
Open/close the Main On/off = No movement
Rotation counterclockwise (A) Rotation clockwise (B)
