General info
Before the AutoHeight boom height control system will function properly, some information about the sprayer, tractor and
connected sensors is necessary.
Hydraulic hook-up
Tractors vary in design regarding the hydraulic system - either constant flow (open centre) systems or variable flow (closed
centre) systems. The open centre hydraulics block needs to be set for the system the tractor uses, whether open centre
hydraulics or closed centre variable system with load sensing will be used.
÷
NOTE! It is strongly recommended to use a tractor with a closed center or load sensing variable hydraulic system in
combination with the AutoHeight boom height control system, as an open centre system without load sensing may
heat the oil excessively.
÷
NOTE! Running AutoHeight at high sensitivity will increase heat build-up of the oil. Specially when AutoHeight
system is used with tractors that has an open centre system without load sensing, it may require lower sensitivity
settings to avoid overheating of hydraulic oil.
The valve (1) on the side of the block is factory set for open centre
hydraulics, but if closed centre hydraulics will be used (also in
combination with load sensing) then screw in the valve.
Certain tractor models are able to use Load Sensing without connecting
an external sensing line. But if optimal sensing control pressure cannot
be obtained, an external sensing line needs to be mounted (3). Please
consult your tractor dealer for correct setup and correct connection.
Before operating the hydraulics, the valve should be adjusted according
to the specific tractor model. If you are unsure of the type of hydraulic
system of your tractor, please consult your tractor dealer.
Schedule with combinations of settings for flow element and circuit
value:
*if tractor requires pressure relief, contact your tractor dealer for further advice.

WARNING! Always be sure to fully extract or retract the open/closed centre selection valve (1). Failure to do so may
cause damage to vital pump parts.
±
WARNING! It is of essential importance that connectors on the sensing line are kept totally clean. Failure to do so may
result in impurities entering the pump and thereby causing damage to vital pump parts.
Control panel
When the control panel is turned on for the first time, the AutoHeight panel guides the operator through the Automatic
System Setup (This is normally done by your HARDI dealer). This procedure is described in “Automatic System Setup” on
page 24. Normally the AutoHeight system will automatically configure and calibrate itself to the sprayer. If this process does
not produce the desired results, perform Manual System Setup described in “Manual System Setup” on page 28. From time
to time it may be necessary to ReTune the AutoHeight electronics to your sprayer's hydraulics. This procedure is described
in “Retune” on page 27.
