Gravimetric Batch Blenders w/Mitsubishi Control Chapter 8: Addendum 93
Feed Calibration Options Screen
This screen allows you to perform the feeder calibrations for each feeder (in weight per
second). This is useful when the feed calibration is giving you an error message (most
commonly caused by overfilling the hopper during the calibration). Select a feeder and then
follow instructions. An error is shown if the current feeder calibration feed time was too
short, the feed time was too long, or if the hopper weight exceeded 110% of the set batch
weight. In the case that the feeder exceeded 110% (maximum hopper weight) due to a high
rate hopper then the “Batch % for Feeder Cal” setting might be set too high. Consult the
manufacturer if this problem arises. The current feeder calibration values are also shown on
this page. It is not necessary to perform feeder calibrations. The blender will
automatically learn these values during the batch.
Mechanical Options Screen
This screen allows the user to change the number of hoppers, the predetermined gate cycle
time, and the mixer bump time for detecting high level.
The gate cycle time has been measured and set at the factory, but might need to be adjusted if
we change the mechanical design of the gate, solenoids, and air cylinders. This setting will
vary depending on whether you are using a gate or an auger.
