1 Press control lock PS Type pproved ccording to DIN EN 693 Description The press control locks PS in the nominl sizes 06 nd 0 re modulr control locks with EC type pprovl for use in hydrulic presses ccording to the DIN EN 693 sfety regultions. The hydrulic control system conforms to performnce level PL e ccording to DIN EN ISO y using other sfety-relted control system prts, the performnce level PL e cn lso e chieved for the entire mchine. Due to its modulr design, the hydrulic control system cn e dpted to the functionl requirements of the press. A complete hydrulic control system is mde up t lest of the sic module nd counterlnce module. The sic module includes the pump s pressure djustment, the direction control for the press, nd the option of decompressing the piston side of the press cylinder. It lso includes protection ginst un desirle pressure uild-up on the piston side of the press cylinder required in DIN EN 693. The counterlnce module hs direct-cting pressure relief vlve for limiting ginst pressure intensifiction on the ring side of the press cylinder nd monitored directionl vlve. Together with the monitored direction vlve in the sic module, the ltter performs the redundnt nd monitored retining of the press rm. The functionl scope of the press control locks cn e optionlly extended s follows: Proportionl system pressure djustment Sfe set-up speed with pump (only possile in connection with liner position mesurement system) Set-up y grvity Fst dvnce y grvity or with regenertive circuit Counterlnce vi electronic or mechnicl lod holding vlve Accumultor module Additionl functions vi ML longitudinl stcking system Aville models sic module (compulsory equipment) ML function module (option for dditionl functions) Accumultor module (option) Counterlnce module (compulsory equipment) Sndwich pltes (optionl) Your enefits EC type pproved hydrulic control system ccording to DIN EN 693 Modulr nd compct design, functions cn e extended Simple nd roust control system set-up Miniml spce, piping nd mintennce required Cn e expnded to crete complete system The press control locks re optimlly djusted to suit the ppliction nd cn e used regrdless of the trnsmission drive Since the control locks re comined with the vrile-speed KineSys drive systems, dditionl functionlities cn e integrted nd therefore the complexity of the vlve control system cn e reduced Technicl dt Generl dt Nominl sizes Size 06 Size 0 Design Modulr design Weight nd dimensions See pges nd Connections (hydrulic) See pges nd Amient temperture rnge Min. - 0 C to mx C Instlltion position Any, preferly in horizontl position Hydrulic specifictions Nominl sizes Size 06 Size 0 Mximum operting pressure* 350 r 30 r Mximum flow rte in P chnnel 60 l/min 00 l/min Mximum flow rte in T chnnel 80 l/min 0 l/min Operting fluid Hydrulic oil ccording to DIN 554, Prts nd Medi operting temperture rnge Min. - 0 C to mx C Operting fluid viscosity rnge Min. 0 cst to mx. 380 cst Clenliness clss ccording to ISO 4406 Clss 9 / 7 / 4 or clener Electricl specifictions Nominl sizes Size 06 Size 0 Type of voltge Direct current Nominl voltge 4 V Voltge tolernce ± 0 % Protection clss IP 65 ccording to DIN (when instlled correctly) Electricl connection of solenoid vlves Plug ccording to EN (DIN 43650) (not included in the scope of delivery) Electricl connection for switch position monitoring Electricl connection for sensors Mx plug, 4-pin, coding A (not included in the scope of delivery) * Note: When using the counterlnce module S5, mximum = 80 r is permitted.
