`
`• Rotor drive speed
`selection
`
`When the rotor engagement sequence is complete, the rotor speed is
`selected with the rotor drive speed switch on the upper keypads (3 ).
`Rotor drive speed selection is dependent upon the material being
`milled.
`
`Rotor Disengagement
`
`A rotor disengagement command is initiated by pressing and
`releasing the rotor control switch. When this command is received,
`the transmission ECM (2) immediately de-energizes the rotor clutch
`solenoid (12). This action disengages the rotor clutch.
`
`When the rotor disengagement command is initiated, the belt
`tension solenoid ( 13) remains energized for 90 seconds or until the
`rotor stops, whichever occurs first. In this condition, tension is kept
`on the rotor drive system while the rotor comes to a halt.
`
`During the disengagement transition, the rotor drive status is set to
`"Disengaging". In this case, the rotor indicator on the upper
`keypads ( 3) flashes. Once the rotor stops, the rotor drive status is set
`to "Off", and the rotor indicator is extinguished.
`
`NOTE: If a rotor engagement command is received while the rotor
`drive system is disengaging, the rotor drive proceeds to follow the
`normal engagement sequence. To prevent a loss in belt tension while
`the rotor is spinning, the belt tension solenoid ( 14) remains
`energized during the re-engagement.
`
`Rotor Exposure During Reverse Travel
`
`An automatic rotor disengagement feature detects a condition where
`the rotor could come in contact with a surface while the machine is
`traveling in reverse. If this rotor exposure condition is detected, the
`rotor drive is disengaged.
`
`For this feature, the side plate sensors (9), (10), (11) and (12), and
`the moldboard position are monitored. The machine ECM (1)
`monitors the moldboard position sensor (6). The transmission ECM
`(2) monitors the side plate sensors.
`
`When the following parameters are simultaneously true for more
`than 0.5 second, the disengagement feature is activated:
`
`• The propulsion system is operating in reverse.
`
`• The rotor drive status is "On".
`
`• The moldboard is raised above the scratch point or the side plates
`are raised above the scratch point.

`
`QESV TBD DRAFT
`
`NOTE: The "scratch point" is determined to be the lowest point of
`the rotor.
`
`NOTE: A fault in moldboard position sensor or any of the side
`plate position sensors will also activate the disengagement feature.
`
`When an event is detected, a Level 2 warning is activated for 5
`seconds and is logged. The rotor drive status changes to
`"Disengaging" and the normal disengagement sequence is initiated.
`When the rotor disengagement feature is activated, the machine is
`allowed to continue to travel in reverse.
`
`Low Rotor Speed
`
`A low rotor speed feature protects the rotor drive system. This
`feature detects when the drive belt is slipping or when the rotor
`suddenly slows. If either rotor condition is detected, the rotor drive
`is disengaged.
`
`The transmission ECM (2) continuously monitors the rotor speed
`sensor (7) while the rotor drive status is "On". In this state, the low
`rotor speed disengagement feature is activated when either of the
`following parameters are true:
`
`• The calculated rotor speed (engine speed x 0.061) differs from
`measured rotor speed by more than 10 percent for over 1.5
`seconds.
`
`• The rotor decelerates more than 500 rpm/sec within any 40ms
`time frame.
`
`The differing rotor speed condition indicates rotor drive belt
`slippage. When this condition is detected while the rotor is on, a
`Level 2 warning is activated for 5 seconds and is logged. In this case,
`the rotor drive status changes to "Disengaging" and the normal
`disengagement sequence is initiated.
`
`The sudden deceleration condition indicates the rotor has impacted
`an object. When this condition is detected while the rotor is on, a
`Level 3 warning is activated for 5 seconds and is logged. The rotor
`drive status changes to "Disengaging" and the normal
`disengagement sequence is initiated.
`
`NOTE: When the low rotor speed feature is activated, the propel
`system is forced to the neutral state.
