ABSTRACT:
Apparatus for training an operator in theory and practice of electrohydraulic control systems in accordance with a presently preferred embodiment of the invention comprises a plurality of electrohydraulic devices for performing hydraulic operations as differing functions of associated electronic control signals. A plurality of differing electronic controllers are each adapted to generate electronic control signals to operate at least one of the electrohydraulic devices. The electronic controllers bear indicia identifying the controller and associating each controller with corresponding electrohydraulic devices on the training unit. Each controller has a plurality of available input, output and control connections, which may be selectively interconnected with each other and with the electrohydraulic devices by suitable cables for configuring the controller and associated device in a multiplicity of differing operating modes. The electrohydraulic devices are connectable by quick-disconnect hoses to a fluid power source carried by the trainer, and are associated with indicia for generating a visually observable indication of operation at the devices, so that an operator can observe effects of differing electronic control configurations on the devices.
