The changeover plates read the required information for the operation of the empty-loaded changeover devices, i.e. brake weights for each position and the relevant changeover mass of the vehicle.
Automatic empty-loaded changeover devices sense a certain load threshold of the vehicle to automatically adjust the output signal when the mass of a vehicle reaches a defined value. This threshold is the changeover mass. Below this mass the vehicle’s brake system provides a reduced brake force. For the changeover mass or more the high brake force applies.
This document specifies the requirements for the design, testing and quality assurance of empty-loaded changeover devices.
