`Auxiliary Hydraulic System
`
`
`
`The upper section of the control panel consists of the
`elevation control switches. The elevation system has
`four hydraulically adjustable legs, one on each corner
`ofthe machine. These legs control the height and
`angle of the machine. The leg heights are manually
`adjusted by the operator or automatically adjusted by
`the grade & slope system.
`
`Note: The conveyor swing unlock handle located
`under the left operator platform must be locked for
`the elevation system to operate.
`
`All-legs control switches (1) control the four legs of
`the machine simultaneously. The upper switch sends
`a RAISE command to the machine ECM. When this
`switch is pressed and held, the machine ascends.
`uniformly. The bottom switch sends a LOWER.
`command to the machine ECM. When this switch is
`pressed and held, the machine descends uniformly.
`When either switch is released, the machine is held
`at the given elevation.
`
`Left front leg switch (2) and right front leg switch (3)
`allow the front legs to be independently controlled.
`These rocker switches have three control positions:
`RAISE, HOLD, and LOWER. TheHOLD position is
`the spring-centered default position. The RAISED
`position is toward the front of the machine. The
`LOWER position is toward the rear of the machine.
`When either switch is moved toward the front of the
`machine, the corresponding front side of the machine
`is lifted. When either switch is moved toward the rear
`of the machine, the corresponding front side of the
`machine is lowered. When a switch is released from
`either position, the switch returns to the HOLD
`position.
`
`Rear leg control switches (4) control the two rear legs
`of the machine simultaneously. The upper switch
`sends.a RAISE command to the machine ECM.
`When this switch is pressed and held, the back of the
`machine ascends uniformly. The bottom switch
`sends a LOWER command to the machine ECM.
`When this switch is pressed and held, the back of the
`machine descends uniformly. When either switch is
`released, the back of the machine is held at the given
`elevation.
`
`The elevation system has a service height feature.
`When raising the machine, the legs automatically
`stop extending when the. cylinder position reaches
`658 mm (25.9 inch). This position is the “Pre-service”
`location and leaves 50 mm (2.0 inch) of leg travel
`remaining. This remaining travel distance is reserved
`for servicing of the machine, When all the machine
`legs are above the “Pre-service’” position, service
`height indicator (5) is illuminated.
`
`Note: The “Pre-Service” height location also allows.
`for a ride control feature. The ride control system
`uses the remaining leg travel to absorb surface
`irregularities during roading.

`
`
`
`Left side plate control switches (9) and right side
`plate control switches (10) control the position of the
`respective side plates of the cutter box. The upper
`switches send a RAISE command to the machine
`ECM. When either switch is pressed and held, the
`corresponding side plate is lifted. In this case, the
`given hold/raise indicator flashes. The bottom
`switches send a LOWER command to the machine
`ECM. When either switch is pressed and held, the
`corresponding side plate descends. In this case, the
`given float/lower indicator flashes.
`
`Note: During normal operation of the side plates, the
`front cylinder retracts first until 100 mm (3.9 inch)
`above the rear cylinder position. Once this difference
`is met, the rear cylinder retracts. If this difference is
`already present, the side plate retracts uniformly.
`
`Left side plate control switches (9) and right side
`plate control switches (10) also control theFLOAT and
`HOLD modes for the side plates. When any switch is
`released from a RAISE or LOWER command, the
`corresponding side plate is placed in FLOAT mode.
`In this case, the given float/lower indicator is
`illuminated. When either upper switch is pressed
`twice within 0.75 second (i.e. double-click), the
`corresponding side plate is placed in HOLD mode. In
`this case, the given hold/raise indicator is illuminated.
`To take a given side plate out of HOLD mode, either
`control switch is pressed and released once. Over a
`machine key cycle, the default mode is HOLD.
`
`Antislab control switches (11) control the position of
`the antislab assembly at the front of the cutter box.
`The upper switch sends a RAISE command to the
`machine ECM. When this switch is pressed and held,
`the antislab is lifted. In this case, the hold/raise
`indicator for the antislab flashes. The bottom switch
`sends a LOWER command to the machine ECM.
`When this switch is pressed and held, the antislab
`descends. In this case, the float/lower indicator for
`the antislab flashes.
`
`Antislab control switches (11) also control the FLOAT
`and HOLD modes for the antislab. When either
`switch is released from a RAISE or LOWER
`command, the antislab is placed in FLOAT mode. In
`this case, the float/lower indicator for the antislab is
`illuminated. When the upper switch is pressed twice
`within 0.75 second (i.e. double-click), the antislab is
`placed in HOLD mode. In this case, the hold/raise
`indicator for the antislab is illuminated. To take the
`antislab out of HOLD mode, either control switch is
`pressed and released once. Over a machine key
`cycle, the default mode is HOLD.
`
`To fully extend the legs to service height, a RAISE
`command must be held for 3 seconds. The front legs
`are raised to service height independently using left
`front leg switch (2) or right front leg switch (3). The
`rear legs are raised to service height together using
`upper rear leg control switch (4). All four legs are
`raised to service height together using upper all-legs
`control switch (1).
`
`Note: The 3-second timer starts when the leg
`reaches the “Pre-service” position or when the raise
`command is applied with the leg already at this
`position. Therefore, service height is achieved by
`either holding the initial raise command or releasing
`and reapplying the raise command. Once a leg is
`above the “Pre-service” position, the 3 second
`requirement is not needed to initiate a leg raise
`movement.
`
`Note: When upper all-legs control switch (1) is held,
`all four legs will eventually stop at the “Pre-service”
`position. In this case, the 3-second timer is initiated
`when the last leg reaches the “Pre-service” position.
`
`The central section of the control panel consists of
`the rotor chamber control switches. The rotor
`chamber system has four individual, hydraulically
`adjustable circuits. These circuits configure the
`antislab, left side plate, right side plate, and
`moldboard surrounding the chamber.
`
`Moldboard control switches (7) control the position of
`the moldboard at the rear of the cutter box. The
`upper switch sends AaRAISE command to the
`machine ECM. When this switch is pressed and held,
`the moldboard is lifted. The bottom switch sends a
`LOWER command to the machine ECM. When this
`switch is pressed and held, the moldboard descends.
`
`Moldboard control switches (7) also control the
`FLOAT and HOLD modes for the moldboard. When
`either switch is released from a RAISE or LOWER
`command, the moldboard is placed in FLOAT mode.
`When the upper switch is pressed twice within 0.75
`second (i.e. double-click), the moldboard is placed in
`HOLD mode. To take the moldboard out of HOLD
`mode, either control switch is pressed and released
`once. Over a machine key cycle, the default mode is
`HOLD.
`
`Note: Moldboard down-force is controlled through
`the operator displays. For down-force control, refer to
`Auxiliary Hydraulic System, “Operator Display”.
`
`Hold/raise indicators (6) are used for the moldboard
`control system as well as the remaining cutter
`chamber circuits. These indicators are illuminated
`when the given circuit is in HOLD mode. During an
`active RAISE command, the given indicator flashes
`once per second.
`
`Float/lower indicators (8) are used for the moldboard
`control system as well as the remaining cutter
`chamber circuits. These indicators are illuminated
`when the given circuit is in FLOAT mode. During an
`active LOWER command, the given indicator flashes
`once per second.

`placed in FLOAT mode. In this case, the lower
`indicator for the antislab is illuminated. When the
`upper switch is pressed twice within 0.75 second (i.e.
`double-click), the antislab is placed in HOLD mode.
`in this case, the upper indicator for the antislab is
`illuminated. To take the antislab out of HOLD mode,
`either control switch is pressed and released once.
`Over a machine key cycle, the default mode is
`HOLD.
`
`Side plate control switches (8) control the position of
`the respective cutter box side plate. The left keypad
`switches control the left side plate. The right keypad
`switches control the right side plate. The upper
`switch sends a RAISE command to the machine
`ECM. When this switch is pressed and held, the
`corresponding side plate is lifted. In this case, the
`raise indicator flashes. The bottom switch sends a
`LOWER command to the machine ECM. When this
`switch is pressed and held, the corresponding side
`zeke descends. In this case, the lower indicator
`ashes.
`
`Note: During normal operation of the side plates, the
`front cylinder retracts first until 100 mm above the
`rear cylinder position. Once this difference is met, the
`rear cylinder retracts. If this difference is already
`present, the side plate retracts uniformly.

`
`A lower control keypad is at the front-left and the
`front-right sides of the machine. These keypads
`control several auxiliary hydraulic system functions,
`and are mirror images of each other. A vandalism
`cover protects each keypad when the machine is not
`being operated. The front-left control keypad is
`shown in
`Illustration 6 .
`
`The keypads provide input signals to the machine
`ECM through the CAN. The keypad on the right side
`of the machine communicates through CAN “A” . The
`keypad on the left side of the machine communicates
`through CAN “B” . The push-button switches on the
`keypads are momentary-type, digital switches. An
`i
`laa LED indicator is located above each
`switch.
`
`Each keypad is equipped with conveyor swing left
`switch (1) and conveyor swing right switch (2). These
`switches operate the conveyor swing system similar
`to the conveyor joystick on the upper control panels.
`However, the commands from these switches are
`digital and operate the swing circuit at full speed.
`When either switch is pressed, the corresponding
`indicator illuminates.
`
`Each keypad is equipped with conveyor raise switch
`(4) and conveyor lower switch (5). These switches
`operate the conveyor height system in the same
`manner as the conveyor joystick on the upper control
`panels. The commands from these switches are
`digital and operate the height circuit at full speed.
`When either switch is pressed, the corresponding
`indicator illuminates.

`Auxiliary Hydraulic Systemi
`
`
`
`is used for
`Upper rotor service door control switch (1)
`raising the moldboard and opening the rotor service
`door. When this switch is pressed, a moldboard
`RAISE command is sent to the machine ECM. When
`the moldboard is fully raised to unlatch mechanical
`locks, an OPEN command is generated. This
`command opens the rotor service door.
`
`Upper rotor service door control switch (1) will not
`function until the following parameters are met:
`
`*
`
`*
`
`«
`
`The elevation legs must be in service height
`mode.
`
`The rotor drive system must be off.
`
`The propel lever must be in the NEUTRAL
`position.
`
`When the rotor service door is open, the service
`mode of the machine is ENABLED. In this case, the
`following systems are disabled:
`
`‧
`
`¢
`
`‧
`
`The steering system
`
`The propel system
`
`The side plate system
`
`Note: When service mode is ENABLED, side plate
`raise and lower commands are allowed from the
`lower rear keypads ONLY. When neither command is
`active, the side plate is placed in the HOLD mode.
`
`Lower rotor service door control switch (1) is used for
`closing the rotor service door and lowering the
`moldboard. When this switch is pressed, a CLOSE
`command is sent to the machine ECM. When the
`rotor service door is fully closed, a moldboard
`LOWER command is generated. This command
`lowers the moldboard to operating height.
`
`Side plate control switches (2) control the position of
`the respective cutter box side plate. These switches
`and the associated indicators operate the same as
`the side plate control switches on the lower-front
`keypads.
`
`All-legs control switches (3) control the elevation of
`the machine. These switches operate the same as
`the all-legs control switches on the upper-right and
`upper-left operator control panels.
`
`Rear'legs control switches (4) control the elevation of
`the back of the machine. These switches operate the
`same as the rear legs control switches on the upper-
`right and upper-left operator control panels.
`
`Left front leg switch (5) and right front leg switch (6)
`control the elevation of the front of the machine.
`These switches operate similar to the front leg control
`switches on the upper-right and upper-left operator
`control panels. However, these switches are digital,
`whereas the upper control panel switches are analog.

`
`Side plate control switches (8) also control the
`FLOAT and HOLD modes for the side plates. When
`either switch is released from a command, the
`corresponding side plate is placed in FLOAT mode.
`In this case, the lower switch indicator is illuminated.
`When the upper switch is pressed twice within 0.75
`second (i.e. double-click), the corresponding side
`plate.is placed in HOLD mode. In this case, the upper
`Switch indicator is illuminated, To take a given side
`plate out of HOLD mode, either control switch is
`pressed and released once. Over a machine key
`cycle, the default mode is HOLD.
