A coating material dispensing device control system comprising multiple coating material type control valves (74), each valve (74) having a coating material input port, a coating material output port and a control port for controlling the passage of the type of coating material controlled by that particular coating material type control valve (74) from its input port to its output port, means (62, 64) for generating control signals for controlling the multiple coating material type control valves (74), means (66) for multiplexing the control signals, means (70) for demultiplexing the multiplexed control signals, means for coupling the means (62, 64) for generating the control signals to the multiplexing means (66), means (58, 52, 60) for coupling the multiplexing means (66) to the demultiplexing means (70), and means (72) for coupling the demultiplexing means (70) to the multiple coating material type control valves (74). <IMAGE> |
