When the selected rigging winch control handle is moved
back to the haul in position, the Node-4 controller sends a
24 volt output to enable the rigging winch pay out solenoid
HS-54 and shifts the valve to the haul in position. The Node-
3 controller sends a variable 0 to 24 volt output to enable the
accessory system proportional relief solenoid HS-68.
When an accessory valve spool shifts, supply flow to the
other accessory valves is limited. The accessory system
pressure sender monitors the accessory system pressure.
Control handle movement controls the proportional relief
valve hydraulic flow to the rigging winch accessory valve.
Hydraulic fluid leaves the accessory valve and enters the
haul in side of the winch motor to haul in the wire rope.
Return hydraulic fluid from the motor leaves the accessory
system valve and returns to the tank. When the rigging
control handle is moved to neutral, the accessory valve
returns to the center position. The Node-3 controller sends a
zero volt output to disable the accessory system proportional
relief solenoid HS-68.
Cab Tilt
See Figure 1-39, and Figure 1-40.
The cab tilt cylinder is attached to the cab frame. During
normal operation the cab tilt solenoid is motor spooled
where both cylinder ports and the tank port of the valve spool
section are connected in the center position. When an
accessory valve spool shifts, supply flow to the other
accessory valves is limited. The accessory system pressure
sender monitors the accessory system pressure. The cab tilt
switch is on the right side console in operator cab.
When the top of cab tilt switch (raise front of cab) is pushed
and held, an input voltage is sent to the Node-1 controller.
The Node-3 controller sends a 24 volt output to enable the
cab tilt up solenoid HS-56 and shifts the valve to the up
position. The Node-3 controller sends a variable 0 to 24 volt
output voltage to enable the accessory system proportional
relief solenoid HS-68.
Hydraulic fluid pressure at approximately 204 bar (2,959 psi)
flows to the cab tilt accessory valve. Hydraulic fluid exits the
valve and enters the free-flow check valve before entering
the piston end of the cylinder, extending the cylinder rod to
raise the cab front.
Hydraulic fluid from the rod end of cylinder enters the free-
flow check valve before entering the accessory valve and
returns to the tank. When the cab tilt switch is released, the
valve returns to the center position. The Node-3 controller
sends a variable 0 to 24 volt output to disable the accessory
system proportional relief solenoid HS-68.
When the bottom of cab tilt switch (lower front of cab) is
pushed and held, an input voltage is sent to the Node-1
controller. The Node-3 controller sends a 24 volt output to
enable solenoid HS-57 and shifts the valve to the lower
position. The Node-3 controller sends a variable 0 to 24 volt
output to enable accessory system proportional relief
solenoid HS-68.
Hydraulic fluid pressure at approximately 204 bar (2,959 psi)
flows to the cab tilt accessory valve. Hydraulic fluid exits the
valve and enters the free-flow check valve before entering
the rod end of the cylinder, retracting the cylinder rod to lower
the cab front.
Hydraulic fluid from the piston end of cylinder enters the free-
flow check valve before entering the accessory system valve
and returns to the tank. When the cab tilt switch is released,
the valve returns to the center position. The Node-3
controller sends a variable 0 to 24 volt output to disable the
accessory system proportional relief solenoid HS-68.
Crawler Pin Cylinders
See Figure 1-41.
The crawler pin cylinder operation is controlled with the
hydraulic valve handles on the front of the carbody and
programming. Operation of both sets of pin cylinders is
similar. The following description of operation is for the left
side set of crawler pin cylinders.
When a crawler pin handle is moved down to engage the
crawler pins into the crawler track frame, the valve shifts to
allow system pressure to the pin cylinders. The lower
accessory enable pressure transducer senses a pressure
drop and sends an input signal to the Node-1 controller. The
Node-3 controller sends a variable 0 to 24 volt signal to the
accessory system proportional relief solenoid HS-68 to
increase the relief valve setting to approximately 207 bar
(3,002 psi). The system pressure increases to operate the
