Screed Operator Console
(1) Vibratory switch
(2) Vibratory speed setting
(3) Rotary multifunction dial
(4) Mode indicator
(5) Mode selector switchNote: The right screed operator console is shown in the illustration above. The left console and the right console are similar.When the compaction screen is active (shown), the display screen indicates the currently selected vibratory speed setting (2). Vibratory switch (1) is active on the screen when the engine is operating. When the switch is green, the operator can tap the icon to turn on the vibratory system. The vibratory system defaults to off when the engine is started.Note: The active tractor operator station display is similar and can also turn the vibratory system on and off.Mode selector switch (5) and rotary multifunction dial (3) are on each screed operator console. The mode selector switch is a momentary switch. The mode selector switch allows the operator to choose the control function of the rotary multifunction dial. Each press of the selector switch toggles between one of the four control functions, in the clockwise direction.The operator must select the vibratory mode with mode selector switch (5) to adjust the vibratory speed with rotary multifunction dial (3). Vibratory mode indicator (4) is illuminated when the vibratory mode is active.Note: When the vibratory mode is selected, the mode remains enabled for 10 seconds after the last input. When this delay time has expired, the system returns to the default material height mode.Rotary multifunction dial (3) operates a digital encoder. The encoder continuously rotates in either direction. The screed ECM monitors the input signal from the encoder through CAN lines. Counterclockwise rotation of the dial decreases the target vibratory speed to a minimum of 700 rpm. Clockwise rotation of the dial increases the target vibratory speed to a maximum of 3000 rpm. Target vibratory speed is maintained across a machine key cycle.
