5-8-18 Feeder Clean Out
(EZ Recipe Mode Only)
Any feeder in the OS/OA blending system can be emptied and refilled
with a different material. To do a feeder clean out, the operator has to
press the ‘clear’ key from the recipe screen (the first screen that
appears on power up).
Quick Feeder Clean Out
Fdr #1: S-open C-close / Arrows for Others
The dump valve opens as soon as the ‘clear’ 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
a run. Use the arrow keys to open/close feeder number 2, 3, 4, 5 & 6
and the
recipe menu. After entering a recipe, the operator will restart the
blending system, putting it back in normal operation.
Important!
Before starting OS/OA blending systems, each ingredient hopper
in the current recipe must contain material!
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 Time Delay” timer. (See Section
5-8-9). Once the dump delay timer has timed out, the controller will
activate the weigh hopper dump valve, initiating the weigh hopper dump
cycle.
