ABSTRACT:
Apparatus for training an operator in use of electrohydraulics that includes an electric-motor/hydraulic-pump with an integrated fluid sump mounted on a portable support. An electrohydraulic valve on the support is preconnected to the pump, and has at least one solenoid valve responsive to valve control signals for controlling the valve to supply fluid from the pump. A hydraulic cylinder is carried on the support and preconnected to the valve for generating mechanical motion as a function of fluid supplied by the valve from the pump. An electronic controller is mounted on the support. A plurality of electrical connectors are mounted on an operator panel on the support and individually preconnected behind the operator panel to the valve controller, to the solenoid of the electrohydraulic valve and to a mechanism on the panel for generating an operator command signal. The electrical connectors are selectively interconnectable by the operator using suitable removable cables for configuring the controller, command generator and valve in a desired electronic control configuration.
