Setup Remote Control
Setup Remote Overview
NOTE:
The setup remote is covered in section 4 of the
Operator Manual.
for the following.
The setup remote control communicates with the CCM-10
control module using the controller area network bus (CAN
Bus). The crane control modules use the CAN Bus to
communicate with each other.
When the crane control system is on, the selector solenoid
valve (1) is energized, overriding the carbody manual control
manifold (5). It does this by sending a command to the CCM-
10 control module. The CCM-10 control module then sends
a signal to the CCMB11 control module to energize the
selector solenoid valve. The energized solenoid causes the
selector valve to shift position, stopping flow to the carbody
manual control manifold. It then routes the flow to the six-
section lower accessory valve assembly (2).
When a raise or lower command is initiated on the setup
remote transmitter, the transmitter sends the command to
the setup remote receiver. The setup remote receiver then
sends a signal to the CCM-10 control module, which then
sends a signal to the CCMB11 and IOSB22 control modules.
The CCMB11 and IOSB22 control modules then energize
the corresponding jack cylinder solenoids in the six-section
lower accessory valve assembly.
Control of the carbody jack cylinders is as follows:
•
IOSB22
-
Right rear cylinder
•
CCMB11
-
Right front cylinder
-
Left front cylinder
-
Left rear cylinder
Neutral Position Using Setup Remote
for the following.
When the crane control system is on, the selector solenoid
valve (1) is energized. The energized selector valve routes
hydraulic fluid to the six-section lower accessory valve
assembly (2).
When no signal is sent to any of the jack cylinder solenoids in
the six-section lower accessory valve assembly, all the valve
spools are held in the neutral position by the return springs.
Each jack cylinder is held in position by its corresponding
counterbalance valve, which closes and stops the flow to
and from the cylinder.
Extend Carbody Jacks Using Setup Remote
for the following.
NOTE:
The following describes the operation to extend
one carbody jack cylinder. The operation is the
same for all carbody jack cylinders.
With the crane control system on, the selector solenoid valve
(1) is energized, allowing hydraulic fluid to flow to the six-
section lower accessory valve assembly (2).
When a jack extend command is initiated on the setup
remote transmitter, the CCMB11 control module or IOSB22
control module (depending on the jack being controlled)
energizes the corresponding jack cylinder extend solenoid in
the six-section lower accessory valve assembly. The extend
solenoid valve routes pilot hydraulic fluid through an internal
shuttle valve, then to the corresponding valve spool. This
causes the valve spool to shift to a position that allows
hydraulic fluid from the accessory pump to flow to the
corresponding jack cylinder counterbalance valve (4).
Within the counterbalance valves, flow and control is as
follows:
•
At the rod side valve, the hydraulic fluid pressure from
the rod side of the cylinder and the accessory pump
pressure opens the counterbalance valve. As the
cylinder extends, the hydraulic fluid from the rod side of
the cylinder goes through the now open counterbalance
valve, then back to tank.
•
At the piston side valve, the hydraulic fluid from the
accessory pump flows through the counterbalance
bypass check valve (3), then into the piston side of the
cylinder.
