Abstract:
A system for providing preventative maintenance of switchable components includes a load-moving system including one or more switchable components. The system also includes a microcontroller configured to operate the one or more switchable components of the load-moving system, to determine a number of switching events of the one or more switchable components and to perform a preventative maintenance action based on determining that the number of switching events is greater than a threshold number of switching events.
