Method of operating an electronically controlled throttle controller between two modes of operation, including a transition between modes, includes the steps of powering up an electronics package and determining if a short term power out, a long term power out and a loss of CPU control in either short term or long term has occurred. Determining a position of each of throttle, dynamic brake and reverser handles disposed in such throttle controller and a previous mode of operation of such throttle controller to determine current mode of operation. Adjusting an output signal to trainlines according to handles when it is determined that such throttle controller is operating in handle mode. Determining if an RMU command has been received by such throttle controller and positioning outputs of such throttle, dynamic brake and reverser handles to the home position when it is determined that a command has been received from such RMU. A predetermined delay is imposed when such outputs of such throttle, dynamic brake and reverser handles are in a home position after positioning of such throttle, dynamic brake and reverser handles into such home position by an operator of such locomotive and before exiting a handle mode and entering an RMU mode for operation of such throttle controller. Determining if an RMU command was received by such throttle controller after exiting such handle mode and, then, adjusting such output signals to such trainlines when it is determined that an RMU command was received by such throttle controller. |
