Operation of the weighing module
4.1 Commissioning
The commissioning of a weighing channel involves two steps:
Configuration of the scale
Scaling of the equipment
Configuration
The configuration procedure is described in detail in the section on Configuration
(WM_Config)
.
4.1.2. Scaling
Start by running a zero adjustment with
Zero
on the
WM_Weigh
Box. Place the
check weight on the scale and activate the
Full
input on the FBSox
WM_Config
.
This scaling must then be checked by removing the weight, running
Zero
and
weighing the check weight once again with
Weigh
. If the difference is too
great, the whole procedure must be repeated. The scaling value is then stored
automatically and reused at each startup.
4.2 Operation
The operation of the scale normally runs as follows:
Run
Zero
just before weighing, while the scale is still empty. Load the scale. There
are now several possibilities:
● Weigh and analyse continuously with
Weigh
● Wait for the status signal
Still
and read off the final weight with a one-off
Weigh
● During loading of the scale, read off and analyse the differential weight with
Dweigh
on a recurring basis.
Tare calibration can either be performed with
Zero
before each weighing, or it can
be executed automatically.
Automatic zero adjustment
Zero adjustment (tare) is run automatically where the
Autozero
parameter is
set to “1”. If the result from the scale over 20 acquisition cycles is less than the
value defined in
Empty
, the system will treat the scale as empty, and a new zero
adjustment will be carried out.
