Abstract
A method for controlling a water supply system for use with a machine tool is disclosed. The water supply system includes a housing with an interface for supplying electrical energy, a water tank, a line, a pump device, a current-measuring device, a water-pressure-measuring device, and a control device. The method includes activating the pump device if the machine tool is connected to the interface and the motor current of the machine tool exceeds a predetermined threshold value, and deactivating the pump device if the machine tool is connected and the motor current undershoots a predetermined threshold value; or activating the pump device if the machine tool is not connected and the water pressure in the line undershoots a predetermined threshold value and deactivating the pump device if the machine tool is not connected and the water pressure exceeds a predetermined threshold value.
