Original instructions
4.1.2 BASKET
BASKET PROGRAMMEABLE LOGIC CONTROLLER (PLC): - Situated in the basket is the Basket
Control Station. Behind the basket control panel is the Basket PLC. The purpose of the Basket PLC is
to interpret signals received from the Basket Control Station and convert them to a digital signal, which
is then output to the Master PLC for processing.
BASKET DISPLAY UNIT: - Mounted in the Basket Control Station, this gauge receives signals from the
Master PLC to provide a warning indication to the operator for a range of functions. Refer to Section
4.3.2Error! Reference source not found. for further details.
LOAD SENSING CONSOLE (SiOPS
TM
): - This machine incorporates a load sensing basket console
that senses if the operator has been pushed or has fallen against the console. If the load applied to the
front of the console is greater than the pre-determined amount, the footswitch will be disabled to
increase operator safety and reduce the possibility of sustained involuntary operation of the basket
controls. For further information refer to Section 4.3.5.
4.1.3 CHASSIS
MOTION CONTROL VALVE: - This valve comprises several individual components all directly involved
in the hydraulic supply to the wheel drive motors.
In addition the Brake Release Valve (BRV) is also incorporated into this valve block. It is a solenoid
operated dump valve, which controls the brake function on the machine. This valve must be energised
to allow the machine to move. If no voltage is present, the wheel motors will not be able to develop
drive torque, whilst at the same time, the parking brakes will remain engaged. Only when a green
"Power Control" push-button is being used (or the Basket Foot-switch is depressed) in Drive mode will
the BRV operate. If the tilt alarm sensor detects an excessive inclination whilst the booms are raised it
is the BRV which is de-energised to isolate the machine.
4.1.4 POWER TRAY
BASIC PLC (Diesel): - Situated on the power tray, this unit activates engine functions by interpreting
signals received from the Control Stations and converting them to a digital signal for processing.
DIESEL ENGINE/ELECTRIC MOTOR: - A Kubota D722 engine driving a load sensing swash pump
This arrangement allows proportional speed control of all appropriate functions.
