5.15 DR 22 Scale Parameter 1 (AWI)
The weighing parameters that change more often in the process are defined in DR
22. Normally, these parameters are changed for switching materials and are then
sent to the SIWAREX FTA again.
Procedure:
o Define all parameters according to the material properties
o Send DR 22 to the scale
o If required, check parameters using tests

5.15.1 DR 22 - Maximum Weighing Time
The weighing time is started with the start of a weighing procedure. After the
defined time has elapsed, a test is performed to determine whether the weighing
procedure will take longer. If yes then a technology error “Weighing time exceeded”
is generated. The weighing procedure is not influenced by the technology error
message.
