1. A system for remotely operating a machine comprising:
- a remote control unit located remote from the machine, the remote control unit including a plurality of remote control input devices for generating a plurality of remote input signals, one of the plurality of remote control input devices being a propulsion input device for generating a propulsion signal;
a transmitter remote from the machine for transmitting the plurality of remote input signals;
a receiver at the machine for receiving a plurality of remote input signals; and
a controller configured to;
store an input signal absence threshold;
generate an operator generated propulsion command to propel the machine based upon the propulsion signal from the propulsion input device;
generate continued propulsion commands based upon the operator generated propulsion command to continue to propel the machine without receiving additional propulsion signals from the propulsion input device;
determine an interval since generating a previous remote input signal at the remote control unit; and
generate a change in operation command signal upon the interval since generating the previous remote input signal exceeding the input signal absence threshold.

Abstract
A system for remotely operating a machine includes a plurality of remote control input devices including a propulsion input device. A controller generates an operator generated propulsion command to propel the machine and generates continued propulsion commands to continue to propel the machine without additional propulsion signals from a propulsion input device. The controller determines an interval since the generation of a previous remote input signal at the remote control unit and generates a change in operation command signal if the interval since the generation of the previous remote input signal exceeds an input signal absence threshold.
