`
`Output Signals
`
`The machine ECM 2 generates output signals 10 to control
`the
`moldboard position When moldboard commands are generated the
`following components receive direct output signals from the
`machine ECM
`
`Moldboard lift solenoid 9
`Moldboard pressure control solenoid 8
`Moldboard float solenoid 7
`Moldboard boost solenoid 6
`
`Operating Logic
`
`A moldboard command is initiated through the buttons located on
`the operator control station 1 When a moldboard command input
`is received the machine ECM 2 determines the proper output
`signal The moldboard commands are RAISE HOLD and LOWER
`When no command is generated the moldboard is in the FLOAT
`mode
`The moldboard cylinder is equipped with a position sensor 5 that
`monitors the position of the moldboard This information is
`transmitted to the machine ECM
`
`When the moldboard is fully raised the moldboard is within service
`range The service range of the moldboard extends down 0
`365
`mm 0 144 in from the top of the moldboard travel The
`moldboard can be mechanically locked in the service range
`
`The transition range of the moldboard is 366
`in
`
`375 mm 14 4
`
`148
`
`765 mm 148 30 1
`The working range for the moldboard is 376
`in from the top of the moldboard travel The working range is the
`normal operating range for the moldboard
`During a moldboard RAISE command the machine ECM 2
`energizes the moldboard lift solenoid 9 moldboard pressure
`control solenoid 8 moldboard float solenoid 7 and moldboard
`boost solenoid 6 In this case the moldboard is lifted until
`
`the
`command is released or the moldboard reaches the start of the
`transition range

`
`If
`
`the raise command is held for 3 seconds the moldboard will
`the raise command is
`continue to raise into the service range If
`released prior to the time limit the moldboard will switch to FLOAT
`mode
`
`When the moldboard is in the service range the Service Mode
`status is Enabled
`
`Moldboard service range
`
`When the Service Mode status is Enabled machine functions
`are effected as follows
`
`The machine ECM 2 disables the steering system and the
`machine elevation control system
`
`The transmission ECM disables the rotor system propulsion
`system antislab system side plate system and rear leg swing
`system The transmission ECM also engages the park brake and
`locks out control of the brake
`
`NOTE When the Service Mode status is Enabled left and
`right side plate RAISE and LOWER commands are accepted from
`the rear keypad only When side plate commands are inactive the
`plates are placed into the HOLD mode
`
`While the RAISE command is held the moldboard will continue to
`raise into the service range When the RAISE command is released
`the moldboard will switch to FLOAT mode HOLD mode is
`disabled in the service range
`
`NOTE The operator must use the mechanical
`moldboard in the service range
`
`lock to hold the
`
`NOTE If the moldboard remains in FLOAT mode in the service
`range it may lower back into the transition range When this
`happens the requirements to raise the moldboard past the transition
`range must be satisfied In this case the raise command must be held
`for 3 seconds before the moldboard will raise
`
`A moldboard DOWN PRESSURE command is initiated through the
`operator display 4 When this command input is received the
`machine ECM 2 changes the moldboard down pressure status to
`Ccon In this case the machine ECM reads the value of the down
`pressure percent status to determine the proper output signal This
`value is adjustable at any operator display
`
`During a moldboard DOWN PRESSURE command the machine
`ECM 2 energizes the moldboard pressure control solenoid 8 and
`the moldboard float solenoid 7 The signal current
`to the pressure
`control solenoid is proportional to the down pressure percent
`status value The scale is linear between the following values

`
`A down pressure percent value of zero generates a signal current
`of 25OmA
`
`A down pressure percent value of 100 generates a signal current
`of 10OOmA
`
`When the DOWN PRESSURE command is active the moldboard is
`lowered and hydraulic pressure is applied to match the signal The
`hydraulic pressure is limited between 0-2000 kPa 0-290 psi

`Based on operator input from the Joystick keypads and displays
`the machine ECM not shown transmits the side plate commands
`through the CAN lines 3 The transmission ECM 2 analyzes the

`The transmission ECM 2 analyzes information signals from input
`devices to determine side plate control The following devices

`
`The left front side plate sensor 9 and left rear side plate sensor

`
`determine the height and angle of the left side plate
`

`
`When a grade and slope system is installed the sensors are used to
`control
`rotor depth For grade purposes the sensors indicate the
`milling surface location relative to the machine leg elevation and
`rotor cut depth
`
`Side plate commands are initiated through the buttons located on
`
`plate also receives commands from buttons on the propulsion
`
`the operator control station 1 or rear keypad 6 The right side
`joystick 7
`When side plate command inputs are received the transmission
`ECM 2 determines the proper output signal The side plate
`commands are RAISE HOLD and LOWER When no command is
`generated the side plate is in the FLOAT mode
`
`NOTE The left and right side plate commands are managed by the
`transmission ECM in the same manner Therefore the following
`command descriptions are true for each side plate
`During a side plate RAISE command the transmission ECM 2
`energizes the corresponding side plate raise solenoid At the same
`time the ECM also energizes the front and rear float solenoids for
`the corresponding side plate In this case the side plate is lifted until
`the command is released or the fully retracted position is reached
`
`A HOLD command is generated when the RAISE command is
`released and initiated again within 075 second i e double-tap
`During a side plate HOLD command the ECMs do not generate a
`side plate output signal In this case no solenoid is energized and the
`lower until a new command is issued by the
`side plate cannot
`
`operator
`
`During a side plate LOWER command the transmission ECM 2
`energizes the corresponding side plate lower solenoids and float
`the command is
`solenoids In this case the side plate descends until
`released or the fully extended position is reached
`
`When a side plate LOWER command is generated the transmission
`ECM 2 energizes the side plate float solenoids first After a short
`delay of 01 seconds the ECM energizes the corresponding lower
`solenoid This delay allows the float valves to fully open prior to
`energizing the control spool This sequence of events prevents the
`buildup of pressure between the control spool and the cylinders
`
`The side plate FLOAT mode is the default mode when all
`the
`buttons on the keypads are released normally When FLOAT mode
`is active the transmission ECM 2 energizes the side plate float
`solenoids In this case the side plate follows the surface
