Abstract
A system and method for operating a cold planer includes a method for operating a cold planer. In a method, a signal indicative of an operating state is used to determine an operating condition, which is a basis for deciding which spray banks from a plurality of spray banks should be activated. Thereafter, a water flow required to operate the spray banks is estimated and a pump command signal is determined. The pump is operated and a water pressure in a main manifold is monitored such that the pump is controlled using a closed-loop control scheme that receives the water pressure as feedback to maintain a desired water pressure within the main manifold.
