Incresing the pump drive speed cuses the DA control vlve to generte higher pilot pressure with resulting increse in the flow from the pump. Depending on the selected pump operting chrcteristics, incresing system pressure (e.g. mchine lod) cuses the pump to swivel ck towrds smller displcement. Diesel engine overlod protection (nti-stll) is chieved y the comintion of this pressure-relted pump de-stroking, nd the reduction of pilot pressure s the engine speed drops. Any dditionl power requirement, e.g. for hydrulic functions from ttchments, could cuse the engine speed to drop further. his would cuse further reduction in pilot pressure nd thus of pump displcement. Automtic power distriution nd full exploittion of the ville power re chieved in this wy, oth for the trvel drive nd for the implement hydrulics, with priority given to the implement hydrulics. he DA control vlve cn lso e used in pumps with EP, H nd HW control modules to protect the comustion engine ginst overlod. DA closed loop control is only suitle for certin types of drive systems nd requires review of the engine nd vehicle prmeters to ensure tht the pump is used correctly nd tht mchine opertion is sfe nd efficient.

For comintions of multiple units, the lekge must e drined t ech pump. If shred drin line is used for this purpose, mke certin tht the respective cse pressure is not exceeded. In the event of pressure differences t the drin ports of the units, the shred drin line must e chnged so tht the minimum permissile cse pressure of ll connected units is not exceeded in ny sitution. If this is not possile, seprte drin lines must e lid if necessry. o chieve fvorle noise vlues, decouple ll connecting lines using elstic elements nd void ove-reservoir instlltion. In ll operting conditions, the suction nd drin lines must flow into the reservoir elow the minimum fluid level. he permissile suction height h S results from the overll loss of pressure; it must not, however, e higher thn h S mx = 800 mm. he minimum suction pressure t port S must lso not fll elow 0.8 r solute during opertion (cold strt 0.5 r solute).

Before using the xil piston unit, plese red the corresponding instruction mnul completely nd thoroughly. If necessry, these cn e requested from Bosch exroth. Before finlizing your design, request inding instlltion drwing. he dt nd notes contined herein must e dhered to. Depending on the operting conditions of the xil piston unit (operting pressure, fluid temperture), the chrcteristic curve my shift. Not ll vrints of the product re pproved for use in sfety functions ccording to ISO Plese consult the responsile contct person t Bosch exroth if you require reliility prmeters (e.g. MF d ) for functionl sfety. Working ports: he ports nd fstening threds re designed for the specified mximum pressure. he mchine or system mnufcturer must ensure tht the connecting elements nd lines correspond to the specified ppliction conditions (pressure, flow, hydrulic fluid, temperture) with the necessry sfety fctors. he working ports nd function ports cn only e used to ccommodte hydrulic lines. During nd shortly fter opertion, there is risk of urns on the xil piston unit nd especilly on the solenoids. ke pproprite sfety mesures (e.g. y wering protective clothing). Moving prts in control nd regultion systems (e.g. vlve spools) my in certin circumstnces ecome stuck in n undefined position due to contmintion (e.g. contminted hydrulic fluid, rsion or residul dirt from components). As result, the hydrulic fluid flow or uild-up of torque of the xil piston unit will no longer respond correctly to the opertor s commnds. Even the use of different filter crtridges (externl or internl inlet filter) will not rule out fult ut merely minimize the risk. he mchine/system mnufcturer must test whether remedil mesures re needed on the mchine for the ppliction concerned in order to set the consumer eing driven to sfe position (e.g. sfe stop) nd if necessry to ensure it is properly implemented.
