Chapter 7: Operation
Table 7-1 Bulk Feed Tank page fields (cont'd.)
Field Description
Today (value1 / value2) (1) Actual feed weight pulled from the tank or tank group since midnight / (2)
Expected feed usage for today.
Yesterday Feed weight pulled from the tank or tank group yesterday.
Pressing right or left arrows at the bottom of the page give access to feed usage
history for up to seven days.
Bulk Feed Tank may be configured as a single unit or part of a Tank Group . The information in the right
pane is contextual to the selection made in the left pane whether it is:
• a single Bulk Feed Tank ,
• a Bulk Feed Tank within a group
• or a Tank Group .
NOTE: The system has an Auto Tare feature. If the tare calibration of a tank was done with feed in it and
the entered feed weight was lower than the actual weight, it is possible to get a negative weight.
In this case, the feed weight on screen will display zero (never a negative value) until the next
feed delivery. The measured tank weight at the beginning of this feed delivery will become the
new empty tank weight replacing the tare calibration value. The empty tank weight, feed weight
and total weight will be adjusted accordingly.
EXAMPLE: A successfully tare calibration on a tank gives the following results on screen:
• Empty tank : 2000 lbs
• Feed weight : 1000 lbs
• Total weight : 3000 lbs
User estimation of feed at calibration was inaccurate. After a feeding ongoing event, the total tank
weight dropped to 1500 lbs which represents -500 lbs of feed. On the controller, the readings will
be:
• Empty tank : 1500 lbs
• Feed weight : 0 lbs
• Total weight : 1500 lbs
A feed delivery of 10 000 lbs occurs. On the controller, the readings will be:
• Empty tank : 1500 lbs
• Feed weight : 10 000 lbs
• Total weight : 11 500 lb
The auto tare feature re calculates the empty tank weight each time the tank gets empty which
replaces the tare calibration value.
