ACCESSORY SYSTEM COMPONENTS
Accessory Systems
Accessory system components include the rotating bed
jacking cylinders, adapter frame pins, boom hinge pins, mast
pins, mast raising cylinders, cab tilt, and rigging winch.
The accessory pumps are the hydraulic pressure source to
operate accessory system components. The accessory
system proportional relief valve is controlled by node-5
controller. The accessory system and the high pressure
accessory system pressure are monitored by separate
pressure senders. During normal operation the relief valve is
set at approximately 150 psi (10 bar). Excess supply flow
from fixed displacement accessory pump is dumped through
valve to tank. When a component of either accessory system
is enabled, an input signal is sent to node-1 controller. Node-
5 controller sends a variable 0 to 24 volt signal to accessory
system proportional relief valve solenoid to increase the
relief valve setting up to 3,000 psi (207 bar), except for mast
raising cylinders where the pressure is 4,000 psi (276 bar).
The accessory systems pressure increases to operate
selected component.
Power is available to hand-held radio remote control when
Setup Remote mode is selected, engine is running, and
power button is pressed.
