Abstract
A counterweight removal protection system and a method of controlling removal of the counterweight to avoid damage to an imaging sensor system of a work vehicle, such as an excavator. The imaging sensor system includes an imaging sensor supported by the counterweight and configured to transmit an imaging sensor signal to a vehicle controller to determine the state of the imaging sensor signal. A user interface in the work vehicle includes a selectable touch button to enable removal of the counterweight depending on the state of the imaging sensor signal. An interlock device prevents lowering the counterweight based on the state of the imaging sensor signal. In one embodiment, the imaging sensor signal is a heartbeat signal.
