3.21 Electronic control system of front lift linkage
The front lift linkage (FLL) is controlled by electrohydraulic system, the electronic
part of which include control panel 4 (figure 3.21.1), electronic unit 5, position sensor 1,
push-button switches 2, connecting harnesses 3 and 8, that connect among yourselves all
system elements and transmit control signals to distributor electromagnets of uplifting 7
and lowering 6.
The system is controlled from control panel 4 (figure 3.21.1) similar to control of rear
lift linkage with one difference, that in FLL control system are no force sensors, therefore
there are no force and mixed control modes.
In FLL control system is installed position sensor 1 of rotating type. The adjustment
of FLL position sensor is described in subsection 3.16.5 ¨ Hydraulic systemof FLL control ¨.
The other components of FLL control system – control panel, electronic unit, push-
button switches are interchangeable with the corresponding components of RLL control
system.
The electric circuit diagram of FLL electronic control system is shown in figure
3.21.2. The list of electric circuit diagram components of FLL electronic control system
shown in figure 3.21.2 is given in the table 3.4.
The system is powered from protection and switching unit from connector X4 of
PASU (figure 2.19.2) through connector XS6 (figure 3.21.2) of FLL ECS harness.
Note – The rules of FLL control are discribed in subsection 2.15 “Front lift linkage
control”.
1 – position sensor; 2 – push-button switches; 3, 8 – connecting harnesses; 4 –
control panel; 5 – electronic unit; 7 – electromagnet of uplifting; 6 – electromagnet of low-
ering.
