Right Console (1) Propel lever (2) Automatic speed control dial (3) Shift switch (4) Parking brake switch | |
Propel lever (1), automatic speed control dial (2), shift switch (3), and parking brake switch (4) are located on the right console.
Propel lever (1) controls the machine's speed and travel direction. A microprocessor is located at the base of the propel lever, inside the right operator's console. The microprocessor detects the position of the lever. The microprocessor sends an input signal to the machine ECM via the CAN lines. The ECM evaluates this signal and input signals from automatic speed control dial (2) and shift switch (3) in order to determine the chosen travel direction and speed.
For forward travel, propel lever (1) must be pushed toward the front of the machine. For reverse travel, the lever must be pulled toward the back of the machine. The travel speed increases the farther the lever is moved away from the center position. The center position of the lever represents the NEUTRAL position.
The microprocessor is calibrated for three positions of propel lever (1). The calibrated positions are the FULL FORWARD position, the FULL REVERSE position, and the NEUTRAL position. The propel lever signal is linear for the full travel of the propel lever.
Terminal "2" of the microprocessor receives power from the propel fuse. Terminal "1" of the microprocessor is grounded. Terminal "3" and terminal "4" of the microprocessor are the CAN lines that send input signals to the ECM.
Automatic speed control dial (2) controls the sensitivity of the propel lever by limiting the maximum speed at which the machine will travel when the propel lever is in the FULL FORWARD position or the FULL REVERSE position. This allows the operator to adjust the impact spacing when using the vibratory system. Maximum travel speed is proportional to the position of the automatic speed control dial. The farther the dial is rotated counterclockwise, the slower the maximum travel speed. The farther the dial is rotated clockwise, the faster the maximum travel speed. When the automatic speed control dial is in the MINIMUM SPEED position, the machine remains in neutral.
Terminal "8" of the microprocessor provides power to automatic speed control dial (2). Terminal "7" of the microprocessor provides the ground for the automatic speed control dial. Terminal "9" of the microprocessor measures the position of the automatic speed control dial. The microprocessor monitors the position of the automatic speed control dial and sends this information to the machine ECM via the CAN lines.
Shift switch (3) is a rocker switch with three positions. The front position of the switch is the ROADING position. The middle position of the switch is the HIGH SPEED position. The rear position of the switch is the LOW SPEED position.
Contact "4" of shift switch (3) is connected to terminal "13" of the microprocessor. Contact "3" of the switch is connected to terminal "14" of the microprocessor. When the shift switch is in the LOW SPEED position, the circuit at terminal "13" of the microprocessor is grounded and the circuit at terminal "14" is floating. When the shift switch is in the HIGH SPEED position, the circuits at terminal "13" and terminal "14" of the microprocessor are grounded. When the shift switch is in the ROADING position, the circuit at terminal "13" of the microprocessor is floating and the circuit at terminal "14" is grounded. The microprocessor monitors the position of the shift switch and sends this information to the machine ECM via the CAN lines.
The shift switch has an integral indicator. The indicator is illuminated when the master lighting circuit is energized.
Parking brake switch (4) is a push button switch with two positions. The parking brake switch is in the ON position when the switch is pushed in. The switch is in the OFF position when the switch is pulled out.
Contact "1" of parking brake switch (4) is grounded. Contact "3" of the switch is connected to terminal "15" of the microprocessor. Contact "2" of the switch is connected to terminal "16" of the microprocessor. When the parking brake switch is in the OFF position, terminal "15" of the microprocessor is grounded and terminal "16" is floating. When the parking brake switch is in the ON position, terminal "15" of the microprocessor is floating and terminal "16" is grounded. The microprocessor monitors the position of the brake switch and relays this information to the ECM through the CAN lines.

Operator Console (5) Fault indicator (6) Speedometer (7) Parking brake indicator (8) Neutral indicator | |
Fault indicator (5), speedometer (6), parking brake indicator (7), and neutral indicator (8) are located on the operator console.
Fault indicator (5) informs the operator of the machine's fault status. The machine ECM controls the fault indicator. When a level 1 fault is active, the fault indicator will illuminate. When a level 2 fault is active, the fault indicator will blink. When a level 3 fault is active, the fault indicator will blink and an audible alarm will sound. The fault indicator is active for one second after the engine start switch is moved to the ON position.
Speedometer (6) displays the machine ground speed in feet per minute (ft/min) and in kilometers per hour (km/h) during machine operation.
Parking brake indicator (7) will illuminate when the interlock solenoid is de-energized. The parking brake indicator will turn off when the interlock solenoid is energized.
Neutral indicator (8) is illuminated when the propel lever is in the NEUTRAL position. The machine ECM controls the neutral indicator at terminal "J2-20".
