Abstract:
1. A method of calibrating a unique proportional solenoid of a unique member of a predesigned class of electrohydraulic control systems that is inclusive of at least one valve controlled by a proportional solenoid that provides an output response in response to an input current, said method comprising: identifying a characteristic equation of the proportional solenoid in the electrohydraulic control system, said characteristic equation including a plurality of coefficients; imbedding into a control unit remotely located from said unique member electrohydraulic control system the characteristic equation; coupling the unique member electrohydraulic control system to a test stand; applying a plurality of different currents to the unique solenoid of the unique member electrohydraulic control system; measuring the output response of the unique member electrohydraulic control system for each of the plurality of currents; identifying unique coefficients in the characteristic equation from the output response measurements; transmitting the unique coefficients in the characteristic equation from the output response measurements; and receiving and flashing the coefficients in a memory of the control unit.
