System Operation
Screed ECM (17) energizes vibratory solenoid (2) when the following conditions are met:
The vibratory status is set to ON.
The parameters for machine forward pave mode have all been met.
The vibratory system enable delay time has elapsed.When vibratory solenoid (2) is energized, the vibratory system is enabled.The vibratory system is disabled and vibratory solenoid (2) is de-energized when any of the following occur:
The vibratory status is set to OFF.
Any of the parameters for machine forward pave mode are not met.The proportional current signal for activating vibratory solenoid (2) is calibrated at zero rpm and at 3000 rpm. The open-loop control system uses linear interpolation to calculate the solenoid currents required between these calibrated speeds.Note: Maximum calibrated vibratory speed can only be achieved in high idle.The material clean-out/warm-up mode is activated from the tractor controls. When this mode is enabled, the vibratory system is activated at 200 rpm, regardless of the vibratory switch position. The interlocks for enabling the clean out/warm up mode are controlled from the machine ECM.Note: For more information on clean out/warm up mode, refer to the Auger and Conveyor System section of this document.Hydraulic Schematic (Vibratory System)
