OperationThe main function of the Spectrum COD System is to store and provide powder forthe application process.

Each Powder Feed Hopper contains a different color powder, which is identified inthe overall system, as a color position. The desired color is selected and triggeredby higher−level system controls or by the operator using the Color−on−Demandcontroller.

The control of the load cells is realized by an external control. Each SpectrumCOD System has a junction box to which the power supply for the load cells mustbe connected.

Hopper Change Procedure

a. Disconnect the hopper fluidisation air supply by releasing the pneumatic quick−disconnect fitting (self sealing),located at the bottom of the hopper.

b. Lift the blue access cover. Disconnect the powder hose quick−connectors from the hopper lid mounts andplace in the purge position located on the back wall of the powder feed station. The quick−connectors are asimple push in fitting.
