Description

Capacity

24.0

5000.0

When the gross weight is greater than the
programmed capacity value the
ERROROVERCAPACITY status bit is set.
This status bit is reset whenever the gross
weight is below programmed capacity
value.

Flow Rate
Time Base

25.0

4.0

Period of time over which changes in
weight are used to calculate the flow rate.
Unit of time is in seconds.

26.0

Reserved

Variation

27.0

*1

Sets the peak to peak variation in weight
values which will be processed

Capture

28.0

*2

Sets the peak to peak variation in
processed weight values that will be used
to calculate the weight value on the scale
after in flight material has settled.

Start Wait

29.0

2.0

Period of time, from the start of the fill
cycle, during which the flow rate is not
calculated. The smallest increment is 0.1
seconds.

Unit of time is in seconds.

Update Time

30.0

2.0

Period of time, after the target weight has
been reached before the measured weight
value is taken. The smallest increment is
0.1 seconds.

Unit of time is in seconds.

Stable

31.0

1.0

The maximum peak to peak percentage
difference in flow rate once the “stable
wait’ period is reached. Values outside of
this range reset the calculation.

If a stable flow rate is not measured the
flow rate portion of the auto-preact
algorithm is not updated.

P gain

32.0

0.05

Gain value used to scale the proportional
error term.

Setting this value to 0.0 disables the
proportional portion of the P+I filter.

Maximum value is 1.0

I gain

33.0

0.65

Gain value used to scale the integral error
term.

Setting this value to 0.0 disables the
integral portion of the P+I filter; and forces
the integral term to 0.0.

Maximum value is 1.0
