The dump valve opens as soon as the “Press to Open Feeder” key is pressed. This easy feeder
clean out option also serves as a means for emptying a batch that is held in the weigh hopper
if the “Press to Open Weigh Hopper” key is pressed when the blender is stopped. To
open/close feeder numbers 2, 3, 4, 5 & 6 press the number next to “Press to Open Feeder” to
select the feeder you desire to empty and the “Press to Close Feeder” key to close the dump
valve. Touch the “Done” key to return to the recipe menu. After entering a recipe, the
operator will restart the blending system, putting it back in normal operation.
Once the operator initiates the run mode of operation, the blending system controller will
begin monitoring the mixer high-level switch. Nothing will happen until the mixer high-level
switch is uncovered. This tells the controller that the mixing chamber is capable of holding
another batch of material.
Once the mixer high-level switch is uncovered, and the weigh hopper has dumped, the system
will meter the ingredients from the supply hoppers, through the metering units, into the weigh
hopper. Each component will be metered individually to allow accurate weighing of the
material.
Each component is metered in the order specified by the “Metering Order” setup. See the
Installation & Setup chapter for further details.
Once the final ingredient specified in the recipe has been metered into the weigh hopper, the
controller will take a final weight reading of the weigh hopper. This will start the “Dump
