Right Console (1) Display (2) Vibratory control switch (3) Propel lever | |
Vibratory control switch (2) is the top switch on the left side of propel lever (3). The vibratory control switch is a push-button switch. The switch contacts are momentary. The vibratory control switch serves as the master switch for the vibratory system.
Propel lever (3) communicates with the machine ECM through the CAN. Each time the operator presses vibratory control switch (2), an input signal is sent to the machine ECM. The machine ECM toggles the status of the vibratory system between off and on with each input signal. When the engine start switch is first moved to the ON position, the status of the vibratory system defaults to off.
The machine ECM analyzes the position of propel lever (3) to determine when to start the vibratory system. The machine ECM also uses the direction input from the propel lever in the control logic of the vibratory system.

Right Console (4) Drum select switch (5) Drum select indicators (6) Vibratory frequency indicators (7) Vibratory frequency switch | |
The keypad is located on the right console. The keypad contains drum select switch (4) and vibratory frequency switch (7).
Each of the above switches provides an input signal to the machine ECM through the CAN. The machine ECM uses the input from these switches to determine the desired operating conditions for the vibratory system.
Drum select switch (4) allows the front and rear vibratory motors to be independently or simultaneously operated. This feature creates the following vibratory drum modes: front drum, dual drum, and rear drum.
Indicators (5) on drum select switch (4) indicate the currently selected vibratory drum mode. The indicators are configured as follows:
- Front drum mode - The indicator on the left side of the drum select switch is illuminated.
- Dual drum mode - Both indicators on the drum select switch are illuminated.
- Rear drum mode - The indicator on the right side of the drum select switch is illuminated.
The machine ECM monitors drum select switch (4) to determine the desired drum vibration mode. The drum select switch allows the operator to cycle the system through the available drum modes.
Each time the operator changes the vibratory drum mode, a pop-up window appears on the display for two seconds. The pop-up window shows the currently chosen mode. The machine ECM stores the currently chosen mode in memory after five seconds have elapsed since the last actuation of a switch. This action allows the system to start up in the last chosen vibratory drum mode after the engine start switch has been cycled through the OFF position.
Vibratory frequency switch (7) allows the operator to select the vibratory frequency mode. With each depression of this switch, the machine ECM toggles the frequency mode. When the vibratory frequency mode is set to low frequency and high amplitude, actuation of the switch changes the mode to high frequency and low amplitude. When the vibratory frequency mode is set to high frequency and low amplitude, actuation of the switch changes the mode to low frequency and high amplitude.
Indicators (6) on vibratory frequency switch (7) indicate the currently selected vibratory frequency mode. The indicator on the left side of the switch is illuminated when the system is in the low frequency and high amplitude mode. The indicator on the right side of the switch is illuminated when the system is in the high frequency and low amplitude mode.
Each time the operator changes the vibratory frequency mode, a pop-up window appears on the display for two seconds. The pop-up window shows the currently chosen mode. The machine ECM stores the currently chosen mode in memory after five seconds have elapsed since the last actuation of the switch. This action allows the system to start up in the last chosen vibratory frequency mode after the engine start switch has been cycled through the OFF position.

Home screen (8) on the operator display shows vibratory speed (9) in vibrations per minute and impact spacing (14) in impacts per foot. Machines equipped with Cat Compact with Compaction Meter Value (CMV), show the CMV value on the display in place of outside temperature (13).
Note: A green drum icon in the upper banner of the display indicates that the vibratory system is in the automatic mode or operating in manual. This icon (not shown in the above illustration) is located to the right of the parking brake icon.
In the manual mode, the machine ECM starts the vibratory system immediately after the operator moves the propel lever out of neutral. The machine ECM disables the vibratory system when the propel lever is returned to the NEUTRAL position. To enable the vibratory system again, the operator must actuate the vibratory control switch on the propel lever.
In the automatic mode, the machine ECM maps vibratory system engagement to the position of the propel lever. This feature allows the operator to choose the machine speed at which the vibratory system will engage.
The vibratory mode can be changed between manual and automatic on the "Main Menu" screen (10) or on the "Machine" screen (12) of the operator display. The "Main Menu" screen can be reached when menu icon (15) is touched. This screen contains auto vibe switch (17).
The "Machine" screen can be reached through the following actions:
- Touch menu icon (15) on home screen (8).
- Choose the "Settings" option (16) on main menu screen (10).
- Choose the "Machine" option (18) on the "Settings" screen (11).
The"Vibe Auto Mode" option (19) on the "Machine" screen (12) contains auto vibe switch (20). When either auto vibe switch is touched, the switch icon slides from side to side. The system is in the manual mode when the icon is on the left side of the box, and the right side is gray. The system is in the automatic mode when the icon is on the right side of the box and the left side is green.
The automatic vibratory engagement parameters can be configured when the "Vibe Auto Mode" option (19) is selected on the "Machine" screen (12). Low, medium, or high settings are available. When the low setting is chosen, the vibratory system engages when the propel lever reaches 40-percent of maximum. The vibratory system disengages when the propel lever is less than 36 percent. When medium is chosen, the vibratory system engages when the propel lever reaches 45 percent and disengages when the propel lever reaches 41 percent. When high is chosen, the vibratory system engages when the propel lever reaches 55 percent and disengages when the propel lever reaches 51 percent.
The machine ECM stores the last active setting in memory 5 seconds after the last time the setting was adjusted. This action allows the system to start up at the last chosen auto vibratory engagement setting after the engine start switch has been cycled through the OFF position.
