Basic InformationH1 Axial Piston Pumps, Single and TandemOperationPressure Limiter ValvesPressure limiter valves provide system pressure protection by compensating the pump swashplateposition when the set pressure of the valve is reached. A pressure limiter is a non-dissipative (nonheat generating) pressure regulating system.Each side of the transmission loop has a dedicated pressure limiter valve that is set independently. Apump configured with pressure limiter must have pressure limiters on both sides of the systempressure loop. The pump order code allows for different pressure settings to be used at each systemport.The pressure limiter setting is the differential pressure between the high and low loops. When thepressure limiter setting is reached, the valve ports oil to the low-pressure side of the servo piston. Thechange in servo differential pressure rapidly reduces pump displacement. Fluid flow from the valvecontinues until the resulting drop in pump displacement causes system pressure to fall below thepressure limiter setting.An active pressure limiter destrokes a pump to near neutral when the load is in a stalled condition.The pump swashplate moves in either direction necessary to regulate the system pressure, includinginto stroke (overrunning) or over-center (winch payout).The pressure limiter is optional for H1 single pumps and not available for tandem pumps.High Pressure ReliefValve (HPRV)and Charge CheckAll H1 pumps are equipped with a combination high pressure relief and charge check valve. Thehigh-pressure relief function is a dissipative (with heat generation) pressure control valve for thepurpose of limiting excessive system pressures. The charge check function acts to replenish thelow-pressure side of the working loop with charge oil. Each side of the transmission loop has adedicated HPRV valve that is non-adjustable with a factory set pressure. When system pressureexceeds the factory setting of the valve, oil is passed from the high pressure system loop, into thecharge gallery, and into the low pressure system loop via the charge check.The pump order code allows for different pressure settings to be used at each system port. When aHPRV valve is used in conjunction with a pressure limiter, the HPRV valve is always factory set abovethe setting of the pressure limiter. The system pressure order code for pumps with only HPRV is areflection of the HPRV setting.The system pressure order code for pumps configured with pressure limiter and HPRV is a reflectionof the pressure limiter setting.HPRV s are factory set at a low flow condition. Any application or operating condition which leads toelevated HPRV flow will cause a pressure rise with flow above a valve setting. Consult factory forapplication review. Excessive operation of the HPRV will generate heat in the closed loop and maycause damage to the internal components of the pump.611062168 Rev EA Oct 2013
Basic InformationH1 Axial Piston Pumps, Single and TandemOperationThe single pump HPRV valve also provides a loop bypass function when each of the two HPRV hexplugs are mechanically backed out 3 full turns. Engaging the bypass function mechanically connectsboth A & B sides of the working loop to the common charge gallery. The bypass function allows amachine or load to be moved without rotating the pump shaft or prime move.Bypass function not available for tandem pumps.C CautionExcessive speeds and extended load/vehicle movement must be avoided. The load or vehicle shouldbe moved not more than 20 % of maximum speed and for a duration not exceeding 3 minutes.Damage to drive motor(s) is possible. When the bypass function is no longer needed care should betaken to reseat the HPRV hex plugs to the normal operating position.System schematic, single pumpM14M6 12R1R2Bypass FunctionC2C1M3 L2MAAF00B F00AHigh pressure relief valve,charge check valveand bypass functionPressure limitervalveM4CWBM5SMBL4P003 418ESystem schematic, tandem pumpM14C1M14C1C2MBX7M3C2MCL3F00BF00BF00AM5High pressure relief valve,charge check valveM4CWPTOM5M4MA A11062168 Rev EA Oct 2013F00ABE C D MDP003 207E7
Basic InformationH1 Axial Piston Pumps, Single and TandemOperationCharge Pressure Relief Valve(CPRV)The charge pressure relief valve maintains charge pressure at a designated level above case pressure.The charge pressure relief valve is a direct acting poppet valve which opens and discharges fluid tothe pump case when pressure exceeds a designated level. This level is nominally set with the pumprunning at 1800 rpm. For external charge flow the CPRV is set according to below table. In forward orreverse, charge pressure will be slightly lower than when in neutral position. The charge pressurerelief valve setting is specified on the model code of the pump.Typical charge pressure increase from 1.2 - 1.5 bar per 10 l/min [17.4 - 21.8 psiper 2.64 US gal/min].Charge pressure relief valve setting for external charge supplyFlowSingle 045/053Tandem 045/053Single 060/068/069/078/089/100/115/130/147/165Single 210/25015 l/min30 l/min22.7 l/min40.0 l/min3.9 [US gal/min]7.9 [US gal/min]6.0 [US gal/min]10.6 [US gal/min]T000 157ESystem schematic, single pumpM14M6 12R2R1C2C1M3 L2MAAF00B F00ACharge pressurerelief valveM4CWBM5SL4MBP003 418ESystem schematic, tandem pumpM14C1M14Charge pressurerelief valveC2MBX7M3C1C2MCL3F00BF00BF00AM5CWPTOMA A11062168 Rev EA Oct 2013M4M5M48F00ABE C D MDP003 207E
Basic InformationH1 Axial Piston Pumps, Single and TandemOperationElectrical DisplacementControl (EDC)EDC PrincipleAn EDC is a displacement (flow) control. Pump swashplate position is proportional to the input commandand therefore vehicle or load speed (excluding influence of efficiency), is dependent only on the primemover speed or motor displacement.The Electrical Displacement Control (EDC) consists of a pair of proportional solenoids on each side of athree-position, four-way porting spool. The proportional solenoid applies a force input to the spool, whichports hydraulic pressure to either side of a double acting servo piston. Differential pressure across theservo piston rotates the swashplate, changing the pump‘s displacement from full displacement in onedirection to full displacement in the opposite direction. Under some circumstances, such as contamination,the control spool could stick and cause the pump to stay at some displacement.EDC-Schematic diagramM14C1C2F00BF00AFeedback fromSwash plateTPP003 478EP003 191A serviceable 125 µm screen is located in the supply line immediately before the control porting spool.EDC OperationH1 EDC’s are current driven controls requiring a Pulse Width Modulated (PWM) signal. Pulse widthmodulation allows more precise control of current to the solenoids. The PWM signal causes the solenoidpin to push against the porting spool, which pressurizes one end of the servo piston, while draining theother. Pressure differential across the servo piston moves the swashplate.A swashplate feedback link, opposing control links, and a linear spring provide swashplate position forcefeedback to the solenoid. The control system reaches equilibrium when the position of the swashplatespring feedback force exactly balances the input command solenoid force from the operator. As hydraulicpressures in the operating loop change with load, the control assembly and servo/swashplate system workconstantly to maintain the commanded position of the swashplate.The EDC incorporates a positive neutral deadband as a result of the control spool porting, preloads fromthe servo piston assembly, and the linear control spring. Once the neutral threshold current is reached, theswashplate is positioned directly proportional to the control current. To minimize the effect of the controlneutral deadband, we recommend the transmission controller or operator input device incorporate a jumpup current to offset a portion of the neutral deadband.The neutral position of the control spool does provide a positive preload pressure to each end of the servopiston assembly.When the control input signal is either lost or removed, or if there is a loss of charge pressure, the springloaded servo piston will automatically return the pump to the neutral position.11062168 Rev EA Oct 20139

Basic InformationH1 Axial Piston Pumps, Single and TandemOperationForward-Neutral-Reverse(FNR) Electric ControlThe 3-Position (F-N-R) control uses an electricinput signal to switch the pump to a full strokeposition.Under some circumstances, such ascontamination, the control spool could stick andcause the pump to stay at some displacement.3-Position electric control, hydraulic schematicM14C1C2F00BF00ATPP003 189A serviceable 125 µm screen is located in thesupply line immediately before the controlporting spool.Non Feedback ProportionalElectric Control (NFPE)P003 193The Non Feedback Proportional Electric (NFPE) control is an electrical automotive control in which anelectrical input signal activates one of two proportional solenoids that port charge pressure to eitherside of the pump servo cylinder.

Basic InformationH1 Axial Piston Pumps, Single and TandemOperationThe Fan Drive Control (FDC) is a non-feedback control in which an electrical input signal activates theproportional solenoid that ports charge pressure to either side of the pump servo cylinder. The singleproportional solenoid is used to control pump displacement in the forward or reverse direction. Thecontrol spool is spring biased to produce maximum forward pump displacement in the absence of anelectrrical input signal. Based on the spring bias spool default forward flow for a CW rotation pump isout of Port B while default forward flow for a CCW rotation pump is out of Port A.The pump displacement is proportional to thesolenoid signal current, but it also depends uponpump input speed and system pressure. Thischaracterisistic also provides a power limitingfunction by reducing the pump swashplate angleas system pressure increases. The pump should beconfigured with 0.8 mm control orifices to provideslowest respponse and maximize system stability.Additionally pressure limiter (PL) valves are used tolimit maximum fan trim speed in both forward andreverse directions.Under some circumstances, such as contamination,the control spool could stick and cause the pumpto stay at some displacement.P301 441FDC-Schematic diagramM14C1C2TF00BF00APP301 442Pump displacement vs. control currentForward100%H1 FDC control p030ar0b prbaDisplacementFan Drive Control (FDC)OptionsF1 (12 V) / F2 (24 V)aNbMax Current p 0rba100%0Reversea Forward Thresholdb Reverse ThresholdN Neutral Override CurrentSignal Current (mA(DCAvg))P301 44311062168 Rev EA Oct 201313
Basic InformationH1 Axial Piston Pumps, Single and TandemOperationManual Over Ride (MOR)All controls are available with a Manual Over Ride (MOR) either standard or as an option fortemporary actuation of the control to aid in diagnostics.Forward-Neutral-Reverse (FNR) and Non Feedback Proportional Electric (NFPE) controls are alwayssupplied with MOR functionality.Unintended MOR operation will cause the pump to go into stroke. The vehicle or device must alwaysbe in a safe condition (i.e. vehicle lifted off the ground) when using the MOR function. The MORplunger has a 4 mm diameter and must be manually depressed to be engaged. Depressing theplunger mechanically moves the control spool which allows the pump to go on stroke. The MORshould be engaged anticipating a full stroke response from the pump. WarningAn o-ring seal is used to seal the MOR plunger where initial actuation of the function will require aforce of 45 N to engage the plunger. Additional actuations typically require less force to engage theMOR plunger. Proportional control of the pump using the MOR should not be expected.Refer to the control flow table in the size specific technical information for the relationship ofsolenoid to direction of flow.P003 204MOR-Schematic diagram (EDC shown)M14C1C2F00BF00AFeedback fromSwash plate1411062168 Rev EA Oct 2013TPP003 205E
