Bosch Rexorth Manifold RexrothFunctionThe press module type C is a hydraulic control for the installation in hydraulic presses according to DIN EN 693:20111) or plastic and rubber machines according to DIN EN 289:2014 and is – according to DIN EN ISO 13849-1 – regarded as “safety-related part of control systems”. The industrial area of application is extended to all machine types which require the safety requirements of the above-specified standards.The press module type C allows the user to design, construct, and/or modify their downstroke piston functions such as press plunger, sheet downholder and ejector according to the general safety requirements.In connection with a suitable electric control, category 4, PLe according to DIN EN ISO 13849-1 can be reached for the following safety measures: Safety measures for the hazard type Extract from standard Performance level (PL) Safety category Avoiding the unintended lowering under own weight DIN EN 693:2011 section 5.2.1, 21) e 4 Avoiding the unintended start-up from the rest position DIN EN 693:2011 section 5.4.1.3 a1) e 4 Shutdown of the dangerous closing movement DIN EN 693:2011 section 5.5.2 b)1) e 4 One-channel, slow velocity in case of command equipment with automatic reset DIN EN 693:2011 section 5.4.1.3 c)1) c 2) 11)In the future DIN EN ISO 16092-32)Higher PL upon requestThe EC type examination certificate HSM15009 has been granted. The tested type complies with the relevant provisions of Directive 2006/42/EC (Machinery).As amendment to DIN EN 693:2011 1) section 5.2.1, 2, unintended lowering under own weight during the retraction of the hydraulic upholding equipment item 140 is safely prevented.Any occurring error is immediately detected by the external safety PLC.Basic module 100A complete press module type C consists at least of the basic module item 100 and the directional valve item 110.The safety-related functions (cat. 1 or 4) are part of the basic design and do not influence the attachment of the additional extension modules item 200 2).The pump and tank connections are arranged laterally and at the bottom and allow for perfect installation into the press. All other actuator ports are arranged laterally 3). The measuring points are always available twice.
