`
`When the conveyordrive system is turned on, solenoids $1
`and S2 energize blocking the pilot oil path to tank. Since
`there is no longer flow through the pilot oil feed orifices,
`there is no longer a pressure drop acrosstheorifices.
`LC1/LC2 pilot oil pressure is now pump outlet pressure.
`
`With LC1/LC2 pilot pressure at pump outlet pressure, the
`valves close blocking the drive oil path to tank. Driveoil
`must now flow through the conveyor motors causing the
`motor output shafts to turn. System pressureswill be
`dependent on conveyor material loads and drive pressures
`can be checked at pressure taps D1 and D2.
`
`Should system pressure in either the first or second stage
`conveyordrive systems reach 190 bar/2,750 psi, relief
`valves R1/R2 will open. With R1 or R2 open, pilot oil once
`again has a return path to tank and an oil pressure drop
`occurs acrossthe pilot feed orifice(s). The pilot oil pressure
`drop allows LC1 or LC2 to open and dump excess drive
`oil/pressure to tank.
`
`Second stage conveyor speed control is accomplished by
`bleeding off a portion of the motordrive oil to tank. The
`conveyor speed control knob on the operator's control
`panel varies the voltage to solenoid VS. Solenoid VS then
`meters a given amount of motordrive oil to pilot operated
`metering valve CS. Drive pressure acts to close valve CS
`from the left, with spring force and metered oil from VS
`acting to open valve CS from the right. The net resultis oil
`is bled from the second stage conveyordrive in proportion
`to the voltage applied to solenoid VS.

`CONVEYOR SWING
`AND ELEVATION
`(SWING RIGHT AND LOWERING)
`
`
`
`Hydraulic power to swing, raise and lower the second stage
`conveyor comesfrom the auxiliary pump. There are two
`solenoid valves in the front hydraulic manifold which are
`controlled by the conveyor swing and raise/lower toggle
`switches.
`
`The schematic is shown with the conveyor swinging right.
`Pressureoil flows through the bottom swing valve envelope
`and an orifice before reaching the swing cylinder. At the
`cylinder pressure oil opens the top relief valve providing a
`tank return path for cap end oil. Pressure oil also unseats
`the bottom check and flows to the cylinder rod end,
`retracting the rod.
`
`The schematic is also shown with the conveyor lowering.
`Pressureoil flows through top envelope of the conveyor
`raise/lower valve to the cap end of the cylinder. Pressureoil
`also openstherelief valve providing a tank return path for
`oil in the cylinder rod end. The cylinder rod is extending.
`
`The relief valve and check valve combinations located at
`the cap ends of the cylinders act as lock valves to prevent
`cylinderdrift.

`Power for conveyor controls comesfrom circuit breaker 1.
`Power distribution to the various switchesis through 103-

`
`Either of the two conveyor on/off switches engages the
`conveyor drive by energizing the conveyorcontrol relay and
`conveyor on/off solenoids through C736-wh. The conveyor
`neutral relay will also be energized, opening the engine start
`circuit (see slide 30). Since the on/off switches are
`momentary switches, the control and neutral relays are
`"latched-on" by 961-br/958-yl once an on/off switch is
`released. The console conveyor-onL.E.D.'s will now be
`illuminated. Toggling an on/off switch to off breaks the
`latch and turns off the conveyordrive.
`
`C736-whalso energizes the second stage conveyor speed
`potentiometer. Turning the potentiometer knob on the
`operator's control panel varies the current to the speed
`control solenoid (C756-bu).
`
`The conveyor swing, raise and lower switches simply close
`the circuit between 103-yl and their appropriate solenoid.
`These switches are momentary switches. The optional
`groundlevel control switches are shown with dashed-line

`
`Pump outlet water flows through thefilters to the shutoff
`solenoid, and to the high pressure washdown pump. When
`the pump clutch is engaged, the shutoff solenoid will also
`be energized allowing water to flow to the control valves
`and spray nozzles. Flow rates to the various nozzle groups
`can be controlled with the water control valves.
`
`Since the high pressure washdown pump inlet is through the
`water spray pump, the spray system should be operating

`
`The CPC engages the water spray system by energizing the

`GRADE AND SLOPE CONTROL SYSTEM
`
`The PM-565 has both manual and automatic control of
`machine frame/rotor elevation. There is also the option to
`select automatic slope control. By controlling machine
`frame elevation and slope, both cutting depth andprofile of
`the cut are produced. Hydraulic cylinders in each machine
`support leg control rotor height and orientation to grade.
`
`Both front and rear machine support legs can be manually
`raised and lowered. The front legs can each beindividually
`raised and lowered with automatic grade and slope controls
`as well. While in automatic grade and slope control, the rear
`legs are stationary at a preset height while the two front
`legs automatically adjust to control cutting depth and
`profile. The rear leg cylinders are plumbedin parallel to each
`other; as oil needs to transfer from one cylinder to another
`to allow the machine to lean during slope control.
`
`The front leg elevation toggle switch (1) manually controls
`both front legs simultaneously, while automatic grade and
`slope operation controls each front leg individually.
`Automatic grade and slope control operation is activated
`with the toggle switch to the left of the manual switch (2).
`
`Rear leg elevation is controlled with a single manual toggle
`switch (3). At the start of a cut, the rear legs are lowered
`to a preset stop point with this switch. Then, the front legs
`adjust cutting depth. Should the cutting depth be greater
`than 229 mm/9Qinches, t he bypass switch (4) is used to
`allow the rear legs to lowerall the way downto the end of

`
`Rear leg elevation hydraulic control is through the rear
`hydraulic manifold. Flow from the auxiliary pump flows into
`manifold port P1 and unseats the check valve. Whenever
`there is normal auxiliary pump output, the DC motordriven
`accessory pump will not operate, and the accessory pump
`outlet check valve will be seated by auxiliary pressure.
`
`Slide 133 showsthe flow of oil to lower the rear legs. The
`rear legs raise/lower switch on the operator's control panel
`energizes the rear leg elevation control solenoid. Auxiliary
`pump outlet oil flows through an orifice and the upper
`envelope of the rear leg elevation valve to the leg cylinder
`rod ends. Pilot pressure oil unseats a lock valve check to
`provide a cylinder cap end tank return path. This tank return
`oil is also orificed through an orifice check to restrict the
`rate of cylinder retract, since machine weightis acting
`against the cylinder cap ends.
`
`Notice how the leg elevation cylinder rod ends and cap ends
`are plumbed together. With this arrangement, pressure in
`the cap ends of both cylinders will be equal as oil is free to
`transfer from one cylinder to another. Therefore the
`machineis free to lean from side to side with front leg
`cross-slope adjustment while keeping equal weight on each
`leg. However, if the machineis fully raised, it is possible for
`a rear leg tolift since there is no cylinder free-travel left in
`the fully extended rods.

`The schematic is also shown with the track park brakes
`released. Brake release pressure is dropped to 69

`
`There are twofront leg elevation solenoids in the front
`hydraulic manifold. These solenoids are proportional. Both
`solenoids are energized simultaneously by the manualfront
`leg elevation switch at a set, stepped-downvoltage. But,
`automatic grade and slope control energizes each solenoid
`individually with a PWM (pulse width modulated) signal. The
`duty cycle of the PWM signal controls the amount the
`solenoid valve opens, and consequently the flow rateofoil
`to the given leg cylinder.
`
`The schematic is shown with both front legs lowering.
`Auxiliary pumpoil is flowing through the bottom envelopes
`of the leg control solenoids to the rod ends of the elevation
`cylinders. This pressure oil opensrelief valves to provide a
`tank return path for oil in the cylinder cap ends. Since the
`leg control solenoids are proportional, the rate of cylinder
`retraction is controlled.
`
`The relief/check valve combinations act as lock valves when
`no voltage is applied to the leg elevation solenoids.

`
`Electrical power for manual elevation control system comes
`from circuit breaker 3. 106-wh provides B+ voltage to the
`elevation manual control switches and auto stopinfrared
`emitter and receiver. Circuit breaker 11, 167-or, provides
`B+ voltage to the auto grade and slope central controller
`and its on/off switch.
`
`The front legs manual elevation switch will override
`automatic control. Power to the switchis from 106-wh,
`through a resistor, to C751-or and to switch terminals 2
`and 5. Switch outputs activate both front leg solenoids
`simultaneously. The resistor in the circuit reduces DC
`amperage (and voltage) to the front leg elevation solenoids.
`
`Therear leg elevation control switch can energize the rear
`legs raise solenoid at any time during normal machine
`operation through C708-pu.
`
`However, rear legs loweris restricted by the auto stop
`infrared emitter/receiver and relay. The rear legs are free to
`lower anytime rear leg elevation is above the predetermined
`set point. The infrared receiver energizes the auto stop
`relay, providing a current path from the switch through the
`relay, and to the rear legs lower solenoid through C71 1-bu.
`When therear legs lower past the set point, the infrared
`receiver de-energizes the auto stoprelay, breaking the
`circuit from the switch to the solenoid. Use of the rear legs
`bypass switch will allow the legs to lower past the set point
`until they bottom out. This feature is used in deep cuts to
`level the machine.

`
`As we have already stated, automatic grade and slope
`controls the front legs only. Auto grade andslopeis
`activated with the on/off switch, applying B+ voltage to
`central controller terminal 5 through C749-gy.
`
`The central controller powers the grade sensors and slope
`sensor through C763-wh. Sensor and controller ground
`returns are through 205-bk to 200 bk.
`
`The extra ground wire from terminal E of the left grade
`sensoris a configuration wire. This extra wire in the left
`grade sensorwiring harnesstells the central controller this
`is the left grade sensor. Both grade sensors themselves are
`identical.
`
`Comm A & B are communication lines. Each sensor is a
`microprocessor, and the communicationlines transfer
`information between the sensors and central controller.
`
`The central controller receives the sensor information and
`processesit (compares the information received to
`programmed grade and slope values). The controller then
`adjusts the front leg elevations as required. PWM (pulse
`width modulated) signals are sent from the controller to the
`appropriate leg control solenoid. The controller varies the
`duty cycle to the solenoids depending on degree of
`correction needed. Increased duty cycle opens the
`proportional solenoid valves more, giving quicker leg
`response.
