RHL Electronic Control System

1 – RHL Control Panel; 2 – electronic unit; 3 –

RHL position control transducer

; 4 – external

pushbutton for the RHL drop control; 5 – external pushbutton for the RHL lifting control; 6 – left-hand draft

transducer; 7 – right-hand draft transducer; 8 – connecting bundles for controlling the electromagnet; 9 –

electric valve for drop; 10 – electric valve for lifting.

The electronic part of the system works

as follows. After starting the engine, the

supply voltage is applied to the elec-

tronic unit (2) of the system. The elec-

tronic unit scans the transducers and

system control elements and, after

analysis, issues the necessary com-

mands to the controller electromagnets.

The system is controlled from either

control panel (1), located in the tractor

cab or by means of the external control

pushbuttons (4, 5) located on the rear

wheel fenders.
