Electronic part of rear lift linkage control include the following components:
- RLL control unit 1 (figure 3.19.1);
- remote buttons 5 of RLL control;
- electronic control unit 2;
- force sensors 10 and 11 of rear lift linkage;
- RLL position sensor 7;
- electromagnetic valves of lowering 8 and uplift 9;
- connecting harness with electrical connectors 4 and 6;
- safety device of RLL ECS 3, situated in PASU.
Electronic part of rear lift linkage control operates in following order. After engine
start supply voltage goes to electronic control unit 2 of RLL ECS. Electronic control unit
inquire sensors, system controls and after analysis gives necessary commands to elec-
tromagnets of the regulator. The system is controlled either with a help of control unit 1
situated in the cabin or with a help of remote control buttons 5, situated on fenders of rear
wheels.
According to position sensor the electronic control system identify the position of
RLL relative to the tractor and at position control ensure keeping of mounting implement in
the defined position relative to the tractor.
According to force sensors the RLL control electronic system determine the force
applied during operation to lift linkage in horizontal axial direction from coupled implement.
At draft control the tillage depth is kept in proportion to created resistance force of imple-
ment. Therefore at tillage e.g. in the mode of draft control, RLL ECS receiving signals from
force sensors shallow up the implement of the tight soil and put the implement deeper in
soft soil.
At combined control the RLL control electronic system take into account the signals
from position and force sensors in proportion to the mode of control set by selector handle
2 (figure 2.14.1).
Note – The rules of RLL control are described in subsection 2.14 “Rear lift linkage
control”. The electric circuit diagram of real lift linkage control is given in subsection 7.2.
“Possible failures in the electronic control system of RLL and FLL guidelines for trouble-
shooting”.
