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.
