is reached; the weighing container is then emptied. Image 5-5 illustrates the
weighing procedure.
5.4.10 DR 4 – Type: filling (subtractive)/(Big-bag)
Automatic Gravimetric Filling Instrument – conforming to OIML R-61 - Automatic
Weighing Instrument (AWI) type. As an automatic weighing instrument of type
gravimetric filling, the scale doses single quantities from a weighing container in
continuous operation until the defined setpoint (fill weight of the big bag) is
reached. The net weight increases with decreasing load on the scale. The scale is
tared before each dosing. Filling the scale is not part of the automatic operation
cycle. Image 5-7 illustrates the weighing procedure.
5.4.11 DR 4 – Type: filling (subtractive) and emptying
Automatic Gravimetric Filling Instrument – conforming to OIML R-61 - Automatic
Weighing Instrument (AWI) type. The scale doses individual amounts from a scale
container in single or continuous operation according to a repetitive schema. The
net weight increases with decreasing load on the scale. The scale is tared before
each dosing. Filling the scale is not part of the automatic operation cycle.
Image 5-7 illustrates the weighing procedure.
5.5 Weighing Steps – Standard weighing procedure
Every weighing procedure can be split into various steps.
Although weighing procedures are different for different operating modes, the
individual steps can be standardised. These standardised steps enable the
evaluation of the scale status at any point in time.
The user can pause the processing of a step by blocking it. The block affects the
start of the step, i.e. SIWAREX FTA switches from step 2 to step for example, but
if step 3 is blocked, it waits at the beginning of step 3 until the block for step 3 is
deactivated.
A released block for a step cannot be used on that step again.
Activating the check stop with the "Check stop" instruction has another effect.
If a check-stop is activated before or during the processing of a step then
SIWAREX FTA completes the current step and switches to "stopped" status. The
"Continue" instruction starts the operation again from the current point.
