Cat ® Command for Dozing, Gen 3.5 Remote Control Operator Console with RFID for D8T Track Type Tractor Caterpillar

Show/hide table

If communication between the remote control machine and the operator console is lost, the machine will continue to execute the last valid command for 2.1 seconds. After a period of 2.1 seconds, the remote control machine will transition to an immediate stop state. The maximum expected travel distance, on level ground with no load, would be 4.2 m (14 ft) in forward and 5.5 m (18 ft) in reverse. Distances are based on a D10T, in second gear forward or in reverse. Personal injury or death may occur if the machine travels into a hazard zone or towards personnel after losing communication. Maintain a safe distance from the machine. Maintain clear line-of-sight with the machine. Understanding the distances stated above, avoid situations that would place the machine in close proximity to the hazard zone, for example, pushing material over a high wall, or operating near infrastructure.

Note: When operating the machine from in front, functionality of the console controls does not change, but the operator perspective of the machine controls will be opposite.

Power Train Control

1. Now that the machine is running, place the machine into high idle using the Engine High/Low Idle button (22).

2. Disengage the Parking Brake switch (12).

   Note: If the machine is equipped with an access ladder, the ladder must be raised prior to disengaging the park brake or raising the blade.

3. Set the desired engine high idle using the High-Idle Engine Speed Select dial (5).

4. Toggle the Implement Lockout switch (10) to the unlock position.

   Note: Ensure that the implements are raised and or stowed prior to moving the machine. Refer to the "Implements" section of this chapter.

5. Place the machine in first gear forward or first gear reverse by moving the Steering/Direction control (13) in the desired direction.

6. To shift gears, rotate the Gear Shift Up / Down knob (14) to the right to upshift. Rotate the Gear Shift Up / Down knob (14) to the left to downshift.

7. To return to neutral, return the Steering/Direction control (13) to the centered position. The Transmission will automatically shift into neutral.

Note: For machines equipped with Terrain, wait approximately 10 minutes to allow the Terrain display to power up prior to operating the machine in remote mode.

Note: Second gear is the highest gear state allowed in remote control operations.

When in remote control mode, the machine will always start in first gear. If the tractor is in second gear forward and the Gear Shift Up / Down knob (14) is used to put the tractor in neutral, then reverse, the tractor will be in first gear reverse. The exception to this action is when the Bidirectional Auto Shift feature is engaged.

The machine has an Auto Kickdown feature. Auto Kickdown will activate whenever a significant decrease in engine speed is detected. When activated the machine will downshift to first gear whether in forward or reverse.

Speed Increments

When the transmission is shifted up or down by using the gear shift up/down knob (14) the transmission will be altered by the value set in this setting. The available gear increments are 0.1 and 0.5, this allows greater control over the machine transmission.

This can be set by accessing the settings second page, then speed increments, then by selecting the desired increment.

Bidirectional/Enhanced Autoshift (EAS) Feature

Illustration 4	g06396916
(A) Reverse is 0.5 gears higher than forward whenever shifting into reverse. Forward is 0.5 gears lower than reverse when shifting into forward (B) 1.0F - 2.5R (C) 2.0F -2.5R (D) Will return to the last gear used for that direction

Enhanced Autoshift (EAS) - EAS is a fuel savings and convenience feature. This feature will act like an automatic transmission. The operator can set a desired track speed, and the machine will automatically adjust the gear and engine speed to get to the desired speed in the most efficient way. The machine will adjust to changing machine load, caused by machine angle, blade load, or ripper drag, and always seeks to keep the same track speed. EAS is independent in the FORWARD and REVERSE directions. When in “Auto" mode, the operator will adjust the desired track speed by using the upshift/downshift controls.

On the console the Auto Shift settings can be found on the second page of the settings menu. Within the Auto Shift menu the currently selected option will have a check beside it. The only options for this setting are on or off.

Bidirectional Autoshift - Bidirectional autoshift allows the operator to preset the FORWARD and the REVERSE gear for directional changes and shifts out of NEUTRAL. If the operator uses the gearshift knob while in NEUTRAL, this action will override the bidirectional settings when going into F / R.

Note: When the bidirectional speed mode is activated and the direction control is in the NEUTRAL position, the digital display window shows "N" only.

Whenever a directional shift or shifting from neutral occurs, the powertrain shifts to the selected gear for that direction by the active mode. If the machine is operating in the 3.0 forward speed with the autoshift mode at 1.0F - 2.5R and a directional shift is requested, the machine will shift directly from 3.0 forward speed to 2.5 reverse speed. If another directional shift is requested, the machine will shift from 2.5 reverse to 1.0 forward. Bidirectional autoshift can be found in the RC console in the settings menu, on the second page.

Once the bidirectional menu is selected Illustration 4 will be displayed. The currently selected option will have a check beside it.

• The open square (white outline with black center) will take into account the current gear and direction. When shifting into reverse it will increase the current gear by 0.5. When shifting into forward it will decrease the current gear by 0.5.

• The 2 setting will shift between 1.0 forward and 2.5 reverse.

• The 3 setting will shift between 2.0 forward and 2.5 reverse

• The closed square (solid white) will return to the last gear used for that direction.

Illustration 5	g06398656

Note: If the machine is run in manual or using an RC station the bidirectional settings has more options see Illustration each setting can be selected.

• The open circle (black outline with white center) will take into account the current gear and direction. When shifting into reverse it will increase the current gear by 0.5. When shifting into forward it will decrease the current gear by 0.5. (identical to Console)

• The 2 setting will shift between 1.0 forward and 2.5 reverse. (identical to Console)

• The 3 setting will shift between 2.0 forward and 2.5 reverse. (Identical to Console)

• The 4 setting will shift between 2.0 forward and 1.6 Reverse. (This is not supported with console)

• The closed circle (solid black) will return to the last gear used for that direction. (Identical to Console)

• The person icon allows the user to program in the gears to be switched between. (This is not supported with console)

1. Set the machine to remote control (RC) mode.

   Note: Refer to the machine "OMM" for more details on the operation of "EAS".

2. On the console access the Bi-Directional settings as follows:

   1. On the console press the button at the bottom right of the display.

   2. Select "Settings".

   3. Navigate to the second page.

   4. Select "Bi-Dir Shift".

   5. Select one of the available options from Illustration 4.

3. On the Remote Control Console, press the button beside the back icon (lower left). Then press the button next to auto shift. Select the desired option.

   Note: When the Bidirectional feature is OFF, use the Gear Shift Up / Down knob (14) to choose the machine transmission gear setting.

When the Bidirectional feature is toggled to the ON position, the setting selected on the Information Display will be displayed on the Console LCD screen.

Note: If no setting is made on the Information Display, Bidirectional/Enhanced Auto Shift default setting is 1F-2.5R.

AutoHold

If the machine is left in neutral for 2 seconds, the service brake will be applied proportionally to bring the machine to a controlled stop. After the machine is stopped, the parking brake will be automatically engaged.

Note: The parking brake status will not be shown by the parking brake status indicator because "AutoHold" is enabled. The parking brake will automatically be disengaged when the machine is placed in forward or reverse.

Engine Speed

Illustration 7	g06246639
(5) High-idle engine speed select dial

The remote control system always starts the machine in low idle.

• Use the Engine High/Low Idle button on the left side of the Operator Console to change between high idle and low idle.

• Use the High-Idle Engine Speed dial (5) to adjust to a steady engine speed when the tractor is in high idle.

• Engine Deceleration lever (1) is a proportional control. Engine Deceleration lever is used to slow the engine speed temporarily from the value that is set by using the High-Idle Engine Speed dial (5).

• The Service Brake lever (2) is a proportional control that is used to slow the tractor speed temporarily.

Note: The Engine Deceleration lever (1) and the Service Brake lever (2) provide the same function in either direction.

Note: The tractor is locked out of third gear during all remote operation. Also, there is a real-time lockout of second gear. When the estimated slopes are greater than the maximum slope that the machine can negotiate in second gear without over speeding the engine, the brakes will automatically be applied to reduce the risk of an engine over speed. The brakes will be automatically applied when the machine is in neutral and on a steep slope.
