28、loaded” and thereby requires the brake force to be adjusted accordingly to achieve the required brake performance. This European Standard also covers manually operated empty-loaded changeover devices and the associated changeover plates. This European Standard specifies the requirements for the desi
29、gn, dimensions, manufacture and testing of empty-loaded changeover devices. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、 and manufacture 4.1 General The design and manufacture of the empty-loaded changeover device shall take the requirements of this clause into account for all intended operating conditions. DIN EN 15624:2011-01EN 15624:2008+A1:2010 (E) 7 4.2 Functional requirements 4.2.1 General 4.2.1.1 The empty-loa
42、ded changeover device shall supply a signal indicating the variation in vehicle load (empty or loaded) to the braking control system; this shall be mechanical or pneumatic. The method of producing the pneumatic signal shall be a mechanically operated pneumatic device, hydraulic to pneumatic converte
43、r device or an elastomeric to pneumatic converter device. 4.2.1.2 The empty-loaded changeover device shall, in all cases, supply an output signal (Lsp), which is a function of the load. 4.2.1.3 The empty-loaded changeover device shall not alter any of the characteristics of the distributor and/or an
44、y associated relay device, when fitted to a vehicle, thereby not altering the characteristics of the brake system, other than to signal the load change and thereby cause the brake cylinder pressure to change between the two states. 4.2.1.4 The design of the empty-loaded changeover device shall eithe
45、r provide a positive output pressure (positive load signal pressure device) or exhaust the output pressure to nominally 0 bar (zero load signal pressure device) in the loaded state dependant on the applicable design requirements. 4.2.1.5 The air consumption of a pneumatic empty-loaded changeover dev
46、ice shall, during running of the vehicle, be minimal and shall not interfere with the normal braking performance of that vehicle. A test which can be used to confirm this is described in A.3.2. 4.2.2 Automatic empty-loaded changeover device 4.2.2.1 General 4.2.2.1.1 An automatic empty-loaded changeo
47、ver device shall change from the empty to loaded state or vice versa, when the vehicle mass exceeds or falls below the changeover mass by a deliberate load change. 4.2.2.1.2 When an automatic empty-loaded changeover device is fitted to a vehicle the changeover shall take place within 5 % of the defi
48、ned vehicle changeover mass. A test which can be used to confirm this is described in A.3.2.1. 4.2.2.1.3 An automatic empty-loaded changeover device may have a damping facility within its mechanism to prevent the effects of transient suspension movement from causing a change of the load signal. 4.2.
49、2.1.4 An automatic empty-loaded changeover device shall be designed to fit to a vehicle in a position to sense the load change of that vehicle, causing a change of state of the changeover device. This may be within the vehicle suspension system or linked to it, in order to sense the load change. 4.2.2.2 Changeover response Where the empty-loaded changeover device does not include integral damping th
