a 2-percent setting, the vibratory system starts after the machine is traveling at 2 percent of maximum speed for the current propel mode. At a 100-percent setting, the vibratory system starts after the machine is traveling at 100 percent of maximum speed for the current propel mode. Auto vibratory increase switch (5) and auto vibratory decrease switch (6) allow the operator to change the vibratory engagement percentage in 2-percent steps.When the auto vibratory engagement percentage is zero, none of the indicators next to the auto vibratory switches are illuminated. When the auto vibratory engagement percentage is 100 percent, all of the indicators are illuminated. The first indicator illuminates when the auto vibratory engagement percentage is set to 2 percent. The second indicator illuminates when the auto vibratory engagement percentage is set to 18 percent. Each subsequent indicator represents a change in the vibratory engagement percentage of approximately 16 percent. Each time the operator actuates vibratory increase switch (5) or vibratory decrease switch (6), a pop-up window appears on the operator display for 3 seconds. The pop-up window shows the currently chosen percentage. Machine ECM number-one stores the last active percentage in memory 5 seconds after the last time a switch was actuated. This action allows the system to start up at the last chosen auto vibratory engagement percentage after the engine start switch has been cycled through the OFF position.Front drum select switch (7) and rear drum select switch (8) allow 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.The indicators next to front drum select switch (7) and rear drum select switch (8) indicate the currently selected vibratory drum mode. The indicators are configured as follows:
In front drum mode, only the middle indicator next to the front switch is illuminated.
In dual drum mode, the bottom indicator next to the front switch is illuminated, and the top indicator next to the rear switch is illuminated.
In rear drum mode, only the middle indicator next to the rear switch is illuminated.Machine ECM number-one operates front drum select switch (7) and rear drum select switch (8) similar to a toggle switch with three positions. When the system is in the front drum mode, a single actuation of the front drum switch keeps the system in the front drum mode. A single actuation of
