Abstract
An apparatus for applying viscous coating material to a surface through spraying devices such as spray guns in which an alarm is activated in the event one or more of the spray guns becomes clogged or otherwise malfunctions. The apparatus includes separate pumps for each of any number of fixtures which supply coating material such as molten wax to spray guns carried by the fixtures. Each fixture includes a valve, and a pressure switch which is operative to sense the fluid pressure within the fixture and activate an alarm at a predetermined level. A controller simultaneously opens at least one spray gun and closes the valve of each fixture to discharge coating material onto a surface. In the event a spray gun becomes clogged or otherwise malfunctions, the fluid pressure within the fixture increases and such increase is sensed by the pressure switch which activates the alarm when the pressure exceeds a predetermined level.
