4.15.5.1 - Operating without Datatronic
• For versions without Datatronic, with the Joystick in
neutral position:
the floating position cannot be used, the hydraulic flow is
at its maximum.
• Joystick in any other position:
move the Joystick in the desired direction(s) and briefly
press button 3,
( Fig. 60 ) to record and set the flow.
If a stored flow rate must be changed or cancelled, operate
the Joystick then press the Memory key (3) for 5 seconds
to restore the maximum flow rate.
4.15.5.2 - Operating with Datatronic 2 (Fig. 52)
When starting the engine, the Joystick is not operational
and the red indicator light is lit.
When the Datatronic 2 has been installed, the correspond-
ing settings in the active window are locked (padlock icon
displayed on half screens Fig. 53).
1. Press button 4 (Fig. 51) to make the Joystick opera-
tional. The red indicator light goes out, the padlock dis-
appears from the half screens and values can be set
on the Datatronic.
2. Move and hold the Joystick in the desired direction to
obtain the desired flow, the flow stops as soon as the
joystick is released.
3. By moving the Joystick to its limit of travel beyond its
locked B1 / C1 floating position, and releasing immedi-
ately, the flow is automated, and when in OFF position
the “
∼
” icon is displayed on the lower screen.
NOTE: The speed and duration of the flow depend on
the parameters previously recorded in the Datatronic.
To cancel the values, press button 3 (Fig. 51) for
approximately 5 seconds (default value 100%).
