Electric Over Hydraulic Controls
The boom and fill pump functions are controlled by
electric over hydraulics solenoids. These solenoids
are energised by functions on the joystick/console in
the cabin and switches on the EZ control station.
The boom functions are controlled by the solenoid
block mounted at the top of the boom centre
section. There is a gauge mounted at the left end of
the block for diagnosis. When a hydraulic function is
used, the hydraulic pressure will increase during that
function.
The boom rest and fill pump are controlled by the
valve block mounted on the cross member of the
chassis under the cabin.
The solenoid valve blocks have various functions.
The directional valve controls oil flow to the desired
circuit. Each particular circuit can be identified by the
tag on the wires attached to the solenoids.
The double operated check valve blocks oil flow
through the solenoid when the solenoid is not
energised. This prevents that function leaking down,
for example if the right hand side of the boom
was tilted up the double operated check valve will
stop oil leaking through when the solenoid is de-
energised and lower the boom, preventing it moving
when the operator is not directing it.
The flow control allows the amount of oil flow to
the hydraulic circuit to be varied thus adjusting the
speed of that circuit. By turning the flow control
adjustment in, clockwise, the flow is reduced thus
reducing the speed at which that hydraulic function
will operate. By turning the flow control out, counter
clockwise, the flow is increased thus increasing the
speed of that hydraulic function.
