7.13 - DUAL CONTROL APPLICATION
7.13.1 - General
The DUAL CONTROL is a system which automatically con-
trols implements in working position and at the end of the
field.
It also allows the rear linkage position to be carried over to
the front linkage position or to the depth wheel position of
a semi-mounted plough for example.
The information necessary for the correct operation of the
system is acquired by sensors, processed by the
"DATATRONIC 3" onboard computer and the electronic
linkage calculator which control the operation of an electro-
hydraulic spool (EHS) valve.
Using this application, the following can be controlled:
- a front and rear implement, with the FRONT DUAL
CONTROL (e.g.: a front roller and a combined rear
seeder (Fig. 154), a front and rear plough, etc.),
- a semi-mounted rear implement, with the REAR
DUAL CONTROL (e.g.: a semi-mounted plough (Fig.
155), a semi-mounted disc tiller, etc. These imple-
ments being hitched to the rear linkage),
- a trailed rear implement with the TRAILED IMPLE-
MENT CONTROL (T. I. C.) (e.g.: a disc tiller (Fig. 156),
a trailed Chisel, etc.). These implements must be
hitched either to the swinging drawbar, or to the lift
arms. This system allows the implement height to be
set according to the wheel slip and the draft applied to
the lift arms (if the implement is hitched to the lift
arms).
To start the DUAL CONTROL application (Fig. 157):
• rotate the encoder (1) to the DUAL CTRL application.
