Implosion Filter Cleaning. When this feature is enabled, the controller periodically pulls a
vacuum on the filter chamber and then releases it to dislodge accumulated dust and debris.
Grinder Empty. This feature allows a station to receive material from a grinder bin. The
level of material in the bin is monitored to assure there is enough material to convey.
Material Sharing. This feature allows multiple pumps (6 max.) to be connected to a
material source. The controller will let one pump at a time draw from the material source.
