16000 SERVICE/MAINTENANCE MANUAL INTRODUCTION
1
When front or rear rotating bed pins switch is placed in the
engage position and held, an input voltage is sent to Node-1
controller. Node-4 controller sends a 24 volt output to enable
rotating bed pins solenoid HS-40 (front selected) or HS-42
(rear) and shifts valve to the engage position. Node-3
controller sends a variable zero to 24 volt output to enable
accessory system proportional relief solenoid HS-68.
Hydraulic fluid pressure at approximately 3,000 psi (207 bar)
flows to rotating bed pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters piston end of selected
pin cylinders, extending cylinder rod to engage the rotating
bed pins. Hydraulic fluid from rod end of pin cylinders leaves
accessory system valve and returns to tank. When rotating
bed pins switch is released, valve returns to center position.
When rotating bed pins switch is placed in the disengage
position and held, an input voltage is sent to Node-1
controller. Node-6 controller sends a 24 volt output to enable
selected front or rear pins solenoid HS-41 (front) or HS-43
(rear) and shifts valve to the disengage position. Node-3
controller sends a variable zero to 24 volt output to enable
accessory system proportional relief solenoid HS-68.
Hydraulic fluid pressure at approximately 3,000 psi (207 bar)
flows to rotating bed pins accessory valve. Hydraulic fluid
leaves the accessory valve and enters rod end of pin
cylinders, retracting cylinder rods to disengage the rotating
bed pins. Hydraulic fluid from piston end of pin cylinders
leaves accessory system valve and returns to tank. When
rotating bed pins switch is released, solenoid HS-41 (front) or
HS-43 (rear) returns to center position. Node-3 controller
sends a variable zero to 24 volt output to disable accessory
system proportional relief solenoid HS-68.
Rigging Winch (Drum 0)
See Figure 1-35, Figure 1-40, and Figure 1-41 for following
procedure.
The rigging winch (Drum 0) is located in the boom butt.
During normal operation the rigging winch solenoid is motor
spooled where both cylinder ports and tank port of valve
spool section are connected in center position. When an
accessory valve spool shifts, supply flow to the other
accessory valves is limited. The accessory system pressure
sender monitors accessory system pressure.
Access rigging winch enable screen from desired system
drum Function Mode screen. When rigging winch screen is
enabled, the computer selects the handle to operate rigging
winch. The computer selected handle display light is 0.
When selected rigging winch control handle is moved
forward in pay out position, Node-4 controller sends a 24
volt output to enable rigging winch pay out solenoid HS-55
and shifts valve to the pay out position. Node-3 controller
sends a variable zero to 24 volt output to enable 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 accessory system pressure.
Control handle movement controls proportional relief valve
hydraulic flow to rigging winch accessory valve. Hydraulic
fluid leaves the accessory valve and enters pay out side of
winch motor to pay out wire rope. Return hydraulic fluid from
motor leaves accessory system valve and returns to tank.
When rigging control handle is moved to neutral, accessory
valve returns to center position. Node-3 controller sends a
zero volt output to disable accessory system proportional
relief solenoid HS-68.
When selected rigging winch control handle is move back to
haul in position, Node-4 controller sends a 24 volt output to
enable rigging winch pay out solenoid HS-54 and shifts valve
to the haul in position. Node-3 controller sends a variable
zero to 24 volt output to enable accessory system
proportional relief solenoid HS-68.
