General InformationLow Level Proximity SwitchesThe adjustable low level proximity switches aredesigned to stop the metering pump when the materialin either pail runs low. The proximity switches are to preventthe machine from pumping air into the materiallines. When the ram is lowered and the fault cleared, thepump can be restarted.Platen - Colorant Tank (Optional)The platen is recommended for materials that are notpourable or self leveling. There is a small plastic platenshipped with each colorant tank. If the colorant is inpaste form, the platen is placed on top of the colorantand should be removed BEFORE filling the tank. If thecolorant that is being used flows easily the platen shouldnot be used because it will sink and block the tank outlet.SolventsThese are rarely used with modern 1:1 silicones.
