1. An emergency override system for a machine, comprising:
- an input device configured to generate a stop signal;
a receiver configured to receive the stop signal;
a controller in communication with the receiver and connectable to a first signal pin and a second signal pin;
the first signal pin configured to indicate a first travel direction of the machine;
the second signal pin configured to indicate a second travel direction of the machine; and
the controller being configured to stop a travel of the machine by applying a threshold voltage to the first signal pin and the second signal pin, when the receiver has received the stop signal.

Abstract
An emergency override system for a machine is disclosed. The emergency override system may have an input device configured to generate a stop signal. The emergency override system may also have a receiver configured to receive the stop signal. The emergency override system may further have a controller in communication with the receiver and connectable to a signal pin, which is configured to indicate a travel direction of the machine. The controller may be configured to stop a travel of the machine by applying a threshold voltage to the signal pin, when the receiver has received the stop signal.

18. A mobile machine comprising:
-
a first signal pin configured to indicate a first travel direction of the machine; a second signal pin configured to indicate a second travel direction of the machine; a platform; a plurality of wheels configured to support the platform; a traction motor coupled to the plurality of wheels and configured to; propel the machine in the first travel direction, when a threshold voltage is applied to the first signal pin; and propel the machine in the second travel direction, when the threshold voltage is applied to the second signal pin; a generator configured to supply power to the traction motor; an override device, including a receiver configured to receive a stop signal; and a controller in communication with the receiver and configured to apply the threshold voltage to the first signal pin and the second signal pin, when the receiver has received the stop signal; and a motor controller configured to direct the generator to stop supplying the power to the traction motor, when the controller has applied the threshold voltage to the first signal pin and the second signal pin. - View Dependent Claims (19)
