IntroductionThe CMA200 is an advanced CAN-Enabledelectro-hydraulic sectional mobile valve withindependent metering that utilizes pressureand position sensors, on board electronics, andadvanced software control algorithms. Whereconventional mobile valves often compromiseon precision or response, the CMA delivers both.The CMA offers high performance with sub micronhysteresis, closed loop control over the spoolposition, and repeatable performance.CMA offers customers the next generation inadvanced mobile valves with unlimited possibilitiesto differentiate your machine capabilities.Key Benefits of this advanced mobile valve include: Precise control maintained for all load conditions Reduction in metering losses / energy management High valve responsiveness Flow Sharing – Pre and Post Comp Capabilities Flexibility in configuration / easily change parameters Command factory-calibrated flow or pressure from eitherwork port Easier communication with the valve Reduced load on the Vehicle CAN bus Advanced Diagnostics for improved reliability and productivity Hose Burst Detection Limp mode Diagnostics on the inlet, tank, load sense, work port pressures,spool position, consumed flow, and oil temperature. Platform can support future software development for futureproduct development. Reliable performance across a broad temperature rangeEATON CMA200 Technical Document E-VLMB-BB002-E1 September 20163

CMA200 Advanced Sectional Mobile ValvesPrinciples of OperationThe work section is comprisedof two independent spoolsthat act as a pair working tocontrol double acting services,or alternatively as single spoolscontrolling a single actingservice (2 single axis servicescan be controlled from any worksection).Demands to each work sectionare transmitted over a CAN Busand power is provided to eachwork section via a single daisychain cable arrangement. Eachwork section has a single pilotvalve comprised of on-boardelectronics, embedded sensors,and two independent 3 position4 way pilot spools driven by alow power embedded microcontroller.The independent pilot spoolscontrol the mainstage spools.Closed loop control of eachwork section is done locallyby leveraging the on-boardelectronics and sensors.Each mainstage spool has itsown position sensor enablingclosed loop position control ofthe mainstage spool.Figure 1: CMA system with Load-Sensing Inlet & a single work-sectionFigure 2: CMA system with Fixed Displacement Inlet & a single work-section6EATON CMA200 Technical Document E-VLMB-BB002-E1 September 2016Further, a pressure sensoris located in each work port,pressure line and tank line.With the up and downstreampressure information known atany time, flow delivered to theservice can be controlled bymoving the spools to create theappropriate orifice area for thedesired flow rate.

CMA Wiring Harness DetailsThere are multiple interconnection options for the CMA200 valvesystems.The following illustrates possible system configuration options.Configuration is dependent on application requirement and isconstrained by the following rules: Sectional construction with up to 8 sections per bank No more than two (2) valve system extenders (VSE) per system Maximum 15 sections per Valve System Module (VSM) If more than 15 work sections are required, this can byaccomplished by using additional CMA systems and theircorresponding VSM. Additional VSMs will appear as another Nodeon the User CAN Network. One VSM and CV required per system If distance between an extension valve bank and the VSM or VSEis less than 6 meters, they can be connected using a daisy chainextension cable. See options on page 12 If distance between valve banks is greater than 6 meters, theymust be connected using a VSE and external wiring harness. Maxdistance between a VSM and VSE is 30 meters. See page TotalInterconnect CAN(ICAN) Wiring Lengths If application specific Electromagnetic Compatibility testingindicates CAN cable shielding is needed, connect CAN shieldas shownUser Cables TerminationUser CAN, or UCAN, is the machine’s CAN network that communicates with the VSM.If the VSM is at the end of the UCAN network, a 120 ohm termination resistor built into the VSM can beused to terminate the UCAN with the installation of a wire jumper, as shown in the left figure below.If the VSM is in the middle of the bus, no UCAN termination is necessary. The UCAN lines to the VSMmust be a stub off of the main CAN harness, as shown in the right figure below.UCAN HIGH ASHIELDICAN LOW AICAN HIGH AUser CAN Device 11 BATTERY 9-32 VDC12 BATTERY 7 ICAN TERMINATEUser CAN NetworkUser CAN ConnectionUser CAN NetworkUser CAN Device 1CAN LCAN HCAN LCAN HUser CAN Device 210 ICAN HIGH B11 ICAN LOW B643UCAN TERMINATEUCAN LOW BUCAN LOW A5UCAN HIGH A298SHIELDICAN LOW AICAN HIGH AUser CAN Device 2Note: Symbol is used to represent twisted pair wires.
