Electrical InstallationS90 EDCProduct overviewTheory of operationThe electric displacement control uses an electrohydraulic Pressure Control Pilot (PCP) valve to controlthe pilot pressure. The PCP converts an electrical input signal to a hydraulic input signal to operate a 4way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servopiston tilts the cradle swashplate, thus varying the pump’s displacement from full displacement in onedirection to full displacement in the opposite direction.The control has a mechanical feedback mechanism which moves the servo valve in relation to the inputsignal and the angular position of the swashplate. The electrical displacement control is designed so theangular rotation of the swashplate (pump displacement) is proportional to the electrical input signal. Dueto normal operating force changes, the swashplate tends to drift from the position preset by the machineoperator. Drift, sensed by feedback linkage system connecting the swashplate to the control valve, willactivate the valve and supply pressure to the servo piston, maintaining the swashplate in its presetposition.Pump displacement versus control currentDisplacement100 %"0"Current mA100 %2423Hydrostatic drive line powerWWarningUnintended vehicle or machine movement hazard. The loss of hydrostatic drive line power, in any modeof operation (forward, neutral, or reverse) may cause the system to lose hydrostatic braking capacity. Youmust provide a braking system, redundant to the hydrostatic transmission, sufficient to stop and hold thevehicle or machine in the event of hydrostatic drive power loss.611022666 Rev BB September 2015
