Minimum material flow (weight/s) [minimumMaterialFlowRate]

The material flow is constantly being measured. The sign of the material flow is always positive
for the selected weighing application.
Example: You have selected the weighing application "Non-automatic weighing instrument –
Removal". In case of weight gain, the material flow gets a negative sign.
As soon as the determined material flow exceeds the limit, this violation is visible in the status
display. Only one positive limit can be specified. A default of "0" permanently deactivates the
status display.

completed and checked cycles.

Meaning
"Maximum corrective action" and "Controller deadband - upper/lower limit" are inter‐
preted as a percentage of the set point (DS 20).
"Maximum corrective action" and "Controller deadband - upper/lower limit" are inter‐
preted in the weight unit.
Meaning
No controller
Proportional controller without fine time controller
Proportional controller with fine time controller
Fine time controller without proportional controller
