2 2/2 Bosch Rexroth AG Hydraulics 7 SL 0 260; 7 SLS ; SL 0 80 D RE 426/0. Structure Filter head with inlet and outlet as well as holder for one or two replacement cartridges. The filter element is firmly integrated into the tank of the replacement cartridge. 7 SLS: Patented version with integrated isolator valve in the filter head for a leakage-free replacement of the replacement cartridge. Replacement cartridge Replacement cartridge with filter element in pleated design with optimized pleat density and various filter media. The filter element is the most important component of the filter system in view of prolonged life and wear protection of the system. The required cleanliness of the operating medium, the initial pressure differential and the dirt holding capacity are the most important criteria for selection. For more information on the filter material please refer to our Filter Elements brochure. Accessories Maintenance indicators They serve the monitoring of the degree of contamination of the replacement cartridge and are available as optical and optical / electronic indicator, with one or two switching points. Bypass valve To protect the replacement cartridge during startup and exceedance of the pressure differential due to contamination. Characteristic curves Our software BRFilterSelect )makes it possible to optimise filter selection, see download area Quality and standardization The development, manufacture and assembly of Rexroth industrial filters and Rexroth filter elements is carried out within the framework of a certified quality management system in accordance with ISO 900:2000. The replacement cartridge filters for hydraulic applications according to RE 426 are pressure holding equipment according to article, section 2..4 of the pressure equipment directive 97/2/EC (PED). However, on the basis of the exception in article, section.6 of the PEG, hydraulic filters are exempt from the PED if they are not classified higher than category I (guideline /9). They do not receive a CE mark.

11 RE 426/0. 7 SL 0 260; 7 SLS ; SL 0 80 D Hydraulics Bosch Rexroth AG /2 Installation, commissioning and maintenance Filter installation Verify operating pressure with nameplate information. Screw the filter head (item ) to the fastening devices, considering flow direction (direction arrows) and servicing height of the replacement cartridge. Remove dust protection plugs from filter inlet and outlet, screw filter in pipeline without tension stress. Connection of the electronic maintenance indicator Establish the connection using a three-wire cable, observe the switching power on the nameplate of the maintenance indicator. Connection versions:. Normally open contact: (sw) + (bl) 2. Normally closed contact: (sw) + 2 (br). Changeover contact: (sw) + 2 (br) + (bl) Warning! Assemble and disassemble filter only when system is depressurized! Tank is under pressure! Do not replace the maintenance indicator while the filter is under pressure! Functional and safety warranty only applicable when using genuine Rexroth spare parts! Service filter only by trained personal! Commissioning Switch on system pump. Maintenance If the red indicator pin reaches out of the maintenance indicator and/or if the switching process in the electronic display is triggered, the maintenance indicator has reached the pressure value and the replacement cartridge has to be renewed. Exchange of the replacement cartridge Switch of the operating pump. Screw off the replacement cartridge and replace it with a new cartridge. When doing so, use the seal / seal ring of the new cartridge. Manually tighten the cartridges of pressure rating 7 bar (7 SL, / 7 SLS ). For assembling the cartridge of pressure rating bar ( SL...), an assembly line can be used. In this connection, do not overtighten the cartridge as there is the risk of damaging the sheet tank. Perform the commissioning as described above. Technical modifications reserved!
