This section highlights the status of the batch weighing system and the quality of the batch
processing.
Info:
This page provides information regarding the stability of the batch hopper itself.
Batch Data:
This page provides the feed results for each component hopper of the last
batch processed by the blender.
Dosing Rate:
This page shows the overall average amount of material fed per time for each
component hopper.
Info
This page provides basic diagnostic information regarding the batch hopper’s weighing sys-
tem.
•
Stable Weight:
If the batch hopper weight signal is varying out of expected tolerance
values, the weight is said to be unstable (Indicator = NO). This indicator verifies the
weighing signal is stable and within tolerances (Indicator = YES).
•
Hopper Weight:
The weight of material reported in the batch hopper.
•
Delta Grams:
The change in weight of material detected in the batch hopper, and
indicates variation (or vibration) that is occurring on the batch hopper.
•
Raw AD Output:
This value is a digital representation of the weight detected by the
batch hopper’s strain gauge sensor. This value includes the weight of the batch hopper
itself and any material present. This value will rise as the batch hopper gains weight,
and falls as the batch hopper loses weight. Excessive variability when the batch hopper
is at rest can produce an unstable weight signal. This number is typically in the range
of 2-3 million with the batch hopper empty. It is in the range of 4-6 million when the
batch hopper is full of material. This value should never be negative or larger than 8
million: if it is, the load cell is most likely defective or damaged.
•
Rate:
The amount of material per time cur-
rently being produced by the blender.
Displayed in pounds/hour or Kilograms/hour.
•
Gram Variance:
The maximum and mini-
mum amount of weight values currently seen
by the weighing system, and indicate the total
vibration range seen by the batch weigh hop-
per.
